No chance for rust and stone impact. Optimum corrosion protection for all BPW components.
Running gear from BPW offers robust technology for a long vehicle life. An important quality feature of our products is
cataphoretic dip-coating with zinc-phosphating (KTLZn). This is a special surface fi nish that provides 5 times more effective
corrosion protection than conventional painting processes. Thin layer corrosion protection processes such as Dacromet®
and Geomet®, as well as chromated surface protection systems, can withstand even the hardest stone impacts.
BPW · THE QUALITY FACTOR / Surface treatment
13
Cataphoretic dip-coating with zinc-phosphating (KTLZn) provides a deep shield and meets the most exacting require-
ments for corrosion protection. For example, KTLZn-coated BPW components can withstand a 504-hour salt-spray
mist test without any problems. BPW is also the fi rst choice when it comes to thin-fi lm corrosion protection proc-
esses: As well as using the familiar, tried-and-tested Dacromet® coating containing chrome VI, BPW is already adopt-
ing the EU end-of-life vehicle directive 2000/53/EC (which is at present only mandatory for vehicles up to 3.5 tonne
gross weight rating) and is in some cases using chrome VI-free coating systems (e.g. Geomet®) instead of the previ-
ous systems containing chrome VI. These systems can be disposed of in an environmentally friendly way, and are
not harmful to health. The result is convincing in all respects: Corrosion, cleaning chemicals and even stone impacts
don’t stand a chance. And the components are ready to be installed without requiring further painting.
How it works Dacromet® and Geomet®: An inorganic, silvery coating is applied to the vehicle components
using an immersion process involving an aqueous suspension of zinc and aluminium fl akes.
The coating is allowed to dry and then baked on at about 300 °C.
KTLZn: The vehicle components are given a painstaking 10-zone pre-treatment (including
zinc-phosphating), after which they are immersed in the cataphoretic dip-coating tank. A di-
rect electric current is applied in order to coat the components with a water-soluble epoxy
resin varnish. This coating is then baked on at 185 °C. Result: The best possible corrosion
protection, even without a topcoat of paint.
Wide-area corrosion protection, even on inaccessible points such as in cavities(5 times better than conventional primers and topcoat paints)
Minimum rust creepage, e.g. after surface damage by stone or chipping strikes
High chemical resistance, e.g. when high-pressure cleaners are used with detergent additives
Longer service life of the entire BPW chassis
Outstanding look: Surfaces without drips orruns and with an even coat thickness
No further topcoat required.Where there are individual requirements for a particular lustre and colour, these finishescan be painted over using inexpensive top-coat systems without pre-treatment
Hard surface: Less transport and installation damage
Easier maintenance and repair procedures
Fewer downtimes
High resistance to heat
Environmentally friendly coating process:No liberation of polluting substances
BPW surface treatment – Features and benefits !
The computer-controlled BPW cataphoretic dip-coating and zinc-phosphating plant represents the cutting edge in the application of corrosion protection in car production and sets the global stand-ard for coating quality in trailer chassis and suspension systems.

We build on the sturdy square profile so that everything runs smoothly when you are driving.
BPW axle beams have been square for years. And for good reason. Despite their low inherent weight, they offer
extreme stability and the greatest possible reliability. It is a BPW design principle that has proven itself millions of
times over. Together with our brakes and suspension systems, the square axle beam offers a sturdy basis for a long
vehicle service life.

The square BPW axle beam consists of two high-quali-
ty, specially rolled axle half-tubes (U-sections) which are
welded together inside and out. The special feature of the
BPW standard axle tube with a 120 mm axle cross section
is its profile shape. Having more material at the corner radii
and less material in the upper and lower areas means
this shape guarantees the longest possible service life. As
a result, the axle cross sections are reinforced at the points
where the load is applied and are optimally shaped to cope
with the load. BPW axle tubes are available with various axle
cross sections and wall thickness values depending on the
axle load and the application conditions. BPW axle stubs are
forged, quenched and tempered. They have two stepped
bearing seats. The female thread on the axle stub end is used
for accommodating the axle bolt (in ECO Plus 2).
The axle stubs and the axle tube are flash butt-welded to-
gether to produce one piece – the BPW axle beam. In this
welding process, the axle tube and the ends of the axle stubs

are heated up to welding temperature by an electric current
applied to their joining faces, whilst at the same time being
forced together. This produces an absolutely homogeneous
connection without any disruptive notches. In contrast to
conventional welding processes, no filler metals are needed.
At the same time, the axle beam is given its camber and toe-
in. Following this, the BPW axle beams are assembled with
the corresponding weld-on components for drum and disc
brakes.
The most important technical data for the axle is the load,
the brake version, the track (SP), the spring centre (FM)
and the air cylinder centres (GM). The spring centre, for
example, is the centre distance between the two spring pads
and usually corresponds with the main chassis beams of the
trailer frame.

Relief for tyres and the driver. For BPW, it’s purely a question of adjustment.
The camber and toe-in of each BPW axle beam are set at the factory. These are minor values, but they have a
big effect on driving. That is because having the right camber and toe-in adds up to greater road safety and ef-
ficiency.
Positive camber – Unladen vehicleCamber is defined as the angle ( ) between the wheel centre plane and a line drawn perpendicular to the plane of the carriageway. The camber is positive if the top of the wheel is angled outwards when the axle is unladen.
Positive camber – Laden vehicleThe bending load on the axle beam when the vehicle is laden causes the wheel to straighten. This means the tyre rolls with optimum road contact when the vehicle is laden (the most critical condition in terms of wear). This avoids uneven, premature tyre wear.
Toe-inToe is the angle ( ) between the longitudinal axis of the vehicle and the wheel centre plane. Toe-in means the front part of the wheel is turned inwards towards the longitudinal axis of the vehicle – i.e. the distance between the front of the tyres (A) is less than the distance at the rear (B). During driving, the rolling resistance of the tyres causes the angle ( ) to be forced back to zero, thereby ensuring stable straight-ahead driving. Without toe-in, the wheels would attempt to run outwards.

Saving costs in an instant. With the mainte-nance friendly ECO principle.
The patented ECO principle from BPW not only offers excellent durability but its internal parts are also easy to
service. For example, the entire wheel can be pulled off after the axle bolt/nut has been unscrewed according to
the efficient Formula 1 principle. The stepped bearing assembly makes hub removal easy without the need for
an additional hub pulling device.
Less time off the road, lower maintenance costs and more straightforward installation because there are fewer procedures required in the normal brake service
Easier to remove throughout the entire life-cycle thanks to the stepped bearing
Use of DIN ISO roller bearings which are available worldwide
No pulling devices required
BPW ECO principle – Features and benefits!
Function: Dismantling couldn’t be
simpler thanks to the patented BPW
ECO principle (European patent 0 407
719 B1). In next to no time, the wheel
(along with the ECO Unit and brake
drum/disc) is pulled off with the axle
bolt according to the Formula 1 princi-
ple. The stepped bearing means there
is no need for pulling devices. The
roller bearings remain in the hub where
they are well protected against dirt and
moisture. Installation is also quick and
easy: Box spanners are all that are re-
quired for the hub cap and axle bolt/
nut. In drum-braked BPW axles, the
wheel can remain fitted on the hub
during removal and installation.

The effective bearing technology of the ECO Unit has been a contributing factor in the success of more than
12 million sold BPW axles. After all, its engaged design guarantees that the highest possible mileages and
serviceability can be achieved. The ECO Unit has undergone consistent further development. Result: The new-
est version, ECO Plus 2. It is impressive with its numerous innovative details that make the chassis even more
convenient for maintenance and repair. In addition to this, it significantly contributes to the reduction in weight of
up to 25 kg over the complete ECO Plus 2 axle system.

the reduced weight but also, for example, the use of glo-
bally available DIN-ISO tapered roller bearings as well as
rapid removal/installation using the central axle bolt, similar
to Formula 1. Innovative design features such as the grease
cartridge, the practical bayonet lock for the hub cap and the
axle bolt with integrated torque limitation underline BPW’s
power of innovation.
Function: The ECO Unit has the ECOSeal wheel bearing seal
with dust and dirt sealing lips in front as well as a pre-
stressed main sealing lip . An integrated grease cartridge
between the two tapered roller bearings provides for reliable
lubrication and effective seals off the grease cavity. The axle
bolt is equipped with integrated torque limiting. A standard
46 mm socket is all that is needed for installation. The hub
cap has a bayonet lock so it is easy to attach and release.
All components together form a closed system and stop dirt
getting in. Nevertheless, the ECO Unit can be dismantled if
the need arises.

BPW offers wheel hubs for wheels with and without offset, for drum or disc brakes, for single or twin tyres. Nor-
mally, wheels with 0 mm (ET 0) or 120 mm (ET 120) offset values are used on trailers and semitrailers. BPW axles
for wheels with zero offset can be equipped with either drum or disc brakes. Wheels with 120 offset can only be
fitted with disc brakes. Disc brakes with zero offset do not wear as much as those with 120 offset.
We accomplish wheels from zero to one hundred and twenty. Depending on what offset you require.
Function: A wheel is made up of a wheel nave , rim and
the tyre. The offset is the distance from the middle of the rim
to the wheel mounting face . If the wheel mounting face
and the middle of the rim are in alignment, this is considered
to be a zero offset. The brake is at the edge of the rim in the
air flow. The air flow acts directly on the disc brake, providing
optimum cooling. This means the pad wear is reduced to a
minimum. The positioning between the brake disc and bear-
ing provide for low bearing temperatures. In conjunction with
the zero offset, the temperature of BPW disc brakes has been
reduced to a value comparable with that of drum brakes. The
wheel load line matches the middle of the rim and the wheel
mounting face, therefore wheel forces are transmitted into
the bearing directly. This structure means that running gear
systems with zero offset are lighter. Running gear systems
with 120 offset are characterised by larger track widths and
spring centres than with zero offset. Also, only one spare
wheel is required for the towing vehicle and the trailer, de-
pending on the version.

right axle system that is a decisive factor in allowing a trailer to drive perfectly. Therefore, you should know all the
important details about wheels, wheel attachments and tyres.
Commercial vehicle tyres have got to meet specific require-
ments. They have to offer an adequate load index and trans-
mit the drive, braking and lateral forces in every situation. The
decisive factors for determining the minimum tyre size are
the axle load (which is derived from the gross vehicle weight)
as well as the permitted maximum speed. According to Eu-
ropean regulation ECE-R 54 (applies to commercial vehicle
tyres), tyres with a maximum speed of 80 km/h (50 mph) or
more must carry a code in addition to the tyre size informa-
tion. This code consists of the load indices for single and twin
tyres (80 to 200) as well as the speed symbol.
The following markings appear on the wheel:
Manufacturer (trademark)
Rim size
Type and/or version name
Date of manufacture
Type code (general certification, ABE)
or (parts) certificate marking

Function: A wheel and tyre consist of a disc wheel – or
wheel spider (in TRILEX wheels) with rim – and a tyre. The
following distinguishing features apply on the basis of the
cross section through the rim:
15° drop centre rims (rim diameters 17.5 inch, 19.5 inch
and 22.5 inch for tubeless tyres)
Taper bead seat rims (rim diameter 20 inch or more)
In the rim designation 11.75 x 22.5, the first number refers to
the rim width and the second to the rim diameter in inches.
The separating character is an „x“ for a one-piece rim (e.g.
drop centre rim) or a „-“ for a multiple piece rim (e.g. taper
bead seat rim).
The wheel nave (or wheel disc) connects the rim to the
wheel hub . It must absorb the vertical, lateral and longitu-
dinal forces which arise and transmit them to the wheel hub
via the wheel studs (wheel bolts). Wheels are centred on their
hubs using stud or hub centring.
In stud centring, the wheel nave (with countersunk stud
holes) is centred using wheel studs with spring washers .
In hub centring, the wheel nave is centred using a centring
flange on the wheel hub (e.g. alloy wheels). The prescribed
BPW tightening torques for wheel attachment are listed in the
valid BPW maintenance regulations and must be observed.
BPW axles are suitable for wheels with either stud or hub
centring. BPW axles are supplied with either collar studs or
spiral studs, depending on the axle type and axle load. Spi-
ral studs are easy to maintain and connect the brake drum/
disc to the hub using a press-fit. As a result, there is no
need for internal nuts. The hub bore is not damaged even
after many removal/installation operations (in contrast to the
situation with splined studs) and the clamping forces for the
wheel studs remain constant. A collar stud also permits re-
peated removal and installation, although it is secured using
an internal nut.

BPW rigid axles are the strong backbone for your trailer. They are rugged, have an extremely high load capacity
and are pleasingly light. After all, with ECO Plus 2, our designers have succeeded in reducing the inherent weight
of each axle by up to 25 kg. For you this means, we clear the way for greater efficiency.
The BPW rigid axle can take even ultra-heavy duty transports in its stride. Whilst being a true lightweight at the same time.

Axles / Rigid axle
Function: The axle stub of the axle beam holds the wheel
bearings and therefore the hub to which the wheel is
mounted by means of the wheel studs . The brake disc –
for axles with disc brakes – or the brake drum is connected to
the hub . The brake anchor plate is welded onto the axle
beam and provides the connection to the brake. The brake
calliper is bolted on disc brake axles. On axles with drum
brakes, it holds the brake shoes. The axle connection joints
the axle to the suspension. The wheels, axle and suspension
form the running gear and are mounted on the chassis of the
trailer or the semitrailer.
The most important feature of a rigid axle is the rigid con-
nection between both ends of the axle through a single-part
axle beam: If the position or angle of one wheel changes, e.g.
spring compression on one side, the other wheels will also be
forced upwards. This also applies to changes in the camber
and toe-in.
The axle transfers the static, dynamic and vertical wheel
loads acting on the wheels, longitudinal forces acting in the
direction of travel (e.g. caused by braking) as well as trans-
verse forces which occur during cornering, for example.

BPW LL self-steering axle with 3-D trailing arms
36
The LL self-steering axle is the economic miracle of all the BPW axles. It shows off its strengths particularly
when tight manoeuvring is required in delivery and distribution haulage. Thanks to its greater manoeuvrability on
corners and when making turns, you benefit from more straightforward vehicle handling, less tyre wear and lower
fuel consumption – over a mileage of 1 million kilometres that adds up to the impressive amounts of up to 10,000
litres of fuel and more than 40 tyres per vehicle. Just work that out for your entire fleet!
Take control of costs, too.With the LL self-steering axle from BPW.
Function: LL stands for load-dependent steering stabilisa-
tion and it describes the unique functional principle of the
BPW self-steering axle. Conventional steering axle designs
require steering stabilisers powered from an external source
– this is not the case with the BPW self-steering axle. The
axle beam and axle stub are connected to undulating thrust
washers via steering pivots. When driving straight ahead
(zero position), the undulations in the thrust washers keep
the wheels on track. The weight of the vehicle presses the
undulating contours of the upper and lower thrust washers
together. The wheels remain stable in the correct straight-
ahead position. When the semitrailer follows the tractor unit
into a curve, the wheel castor ensures the wheels turn in ac-
cordance with the curve radius (the thrust washers slide over
one another). The frictional resistance changes according to
the load on the axle. As a result, a steering angle (of 8° to
27°, depending on the vehicle type) is established according
to the load, and solely by mechanical control. The drag link
connecting the wheels uses a steering lock to prevent the
wheels from steering when the vehicle reverses. The steering
axle means that the unit corners better and follows the same
track as the tractor unit almost identically. The lateral tyre
forces arising are optimally distributed between all the axles,
for example in a 3-axle vehicle. As every axle experiences
significantly lower lateral tyre forces, evidently the mileage of
the front axle increases by up to 50 % - whereas the rear axle
mileage even increases by up to 70 %.

Special transports are not to be taken lightly. Unless you are driving with positive steering axles from BPW.
Due to their length and the large number of axles, high-volume and high-load transporters in particular need a
much larger cornering radius than conventional semitrailer units. A steering system which acts individually on
all wheels – positive steering – is used to enable them to cope with normal roads all the same. Indeed, positive
steering systems are a legal requirement in certain vehicle configurations.

Hydraulic controlTri axle positive steering from the fifth wheel with rigid axles on turntables.
Function: Positive steering can be achieved in a trailer using
a rigid axle mounted to a turntable or with axle stubs
connected together through an axle beam .
Both systems are activated from the trailer fifth wheel.
Axle stub steering differs from the structure of a self-steering
axle in two main ways:
1. The steering pivot and wheel centre are in line with the
axle centreline
2. No locking function is required for reversing
In the positive steering principle, the required steering angle
is imposed on the wheels directly by mechanical or hydraulic
means. This is necessary, if one or more trailer axles have
to be steered individually in order to achieve the required
cornering ability. Positive steering also satisfies the require-
ments for reverse steering. This is a typical situation for food
distribution haulage where vehicles frequently have to be
manoeuvred backwards into very narrow spaces. The steer-
ing angle is based on the varying articulation angle between
the tractor unit and the semitrailer, and is specified by the
design of the overall steering system.

With swinging axles, heavy-duty vehicles can master any critical road surface and heavy ground. This is because
the highly flexible swinging bearings compensate ground uneveness and ensure optimum ground contact all the
time providing greater safety for the driver and the payload. What is more, with swinging axles from the market
leader BPW you benefit from reliable, easily maintained technology with optimised use of space and the advan-
tages of high-volume production.
Top of the class when it comes to difficult ground. BPW swinging axles for heavy-duty vehicles.
Tandem swinging axle

41
Function: A single swinging axle consists of a short axle
beam and two hubs with brakes. Unbraked versions are also
available. The axle beam has a housing for accommodat-
ing the pivot bearings.The swinging axle can therefore be
mounted on a link that is manufactured individually by the
vehicle manufacturer, thereby allowing the axle to pivot. De-
pending on the vehicle configuration, the axle is connected
to the vehicle frame by a turntable bearing or a turret bearing
provided by the manufacturer. In tandem swinging axles, two
swinging axles are connected using an equaliser beam which
is mounted in the centre. Two (tandem) swinging axles are
arranged next to one another in the vehicle.
Tandem swinging axles can cope with all irregularities in the carriage-way by pivoting in both the longitudinally and lateral axis of the vehicle.
Single swinging axles are predominantly used in heavy-duty vehicles with several rows of axles. The lateral pivoting movement of the swing-ing bearings ideally complements hydraulic chassis and suspension systems.
A hydraulic axle load compensating feature ensures that axle loads re-main constant in linked circuits and, depending on the vehicle concept, also offers the possibility of adjusting the level and inclination of the loading platform. As a result, safe operation is assured even under dif-ficult road conditions and when negotiating steep loading ramps. Long vertical travel is possible in this case as well as large pivoting move-ments.

Not everyone wants the standard solution. So it is good to know that made-to-measure special axles are available from BPW.
Wherever a normal axle system doesn’t meet the requirements – such as for box trailers as well as cable and
car transporters – it is necessary to provide the customer with an individual solution. No problem, because BPW
offers the right chassis and suspension products for almost every type of special vehicle. On request, we can
develop a tailor-made solution that takes account of your own special requirements.
Axle stub with ECO Drum
Function: The structure of an axle stub
is basically the same as that in a rigid
axle. However, the axle beam does
not extend from side to side. It ends
shortly after the brake (according to
the customer’s request). The axle stub
suspension which attaches the axle
stub to the chassis is designed indivi-
dually by the vehicle manufacturer.

Function: The force of the brake cyl-
inder acts via the slack adjuster
and causes the brake camshaft to
rotate. The S-cam forces the brake
shoes apart, pressing them against
the inside of the brake drum . When
the brake is released, the brake cam-
shaft rotates the S-cam back to
its neutral position. The brake shoes
are returned to their initial position by

Function: Brake linings and brake drums are wear parts. As
the thickness of the material is reduced, the brake cylinder
stroke increases, meaning that the brake camshaft has to
rotate further. In this case, the function of the ECO Master
slack adjuster provides an automatic adjustment. As a re-
sult, the brake cylinder stroke is always kept within the same,
optimum effective area. The adjustment stroke is designed
so there will always be a sufficient air gap even at higher le-
vels of elasticity and given thermal expansion of the adjacent
components (e.g. the brake drum).
Delivery variants: Brake levers with different shapes and
crank values are available depending on the particular instal-
lation conditions.

Putting the brakes on service costs. The BPW disc brake with tangential bolted connection.
The BPW disc brake not only offers excellent braking properties, but also low service costs. You benefit from shorter
installation and service times thanks to the tangential bolted connection. If you also consider additional advantages
such as the low weight, improved durability and higher volume of abradable material, it becomes clear why the
BPW disc brake is currently setting the standard for brakes in towed vehicles.
Function: When the brake pedal is pressed, the push rod
of the brake cylinder presses against the lever of the
disc brake. The roller mounted eccentrically in the brake
transfers the force onto the bridge . The application force
acts on the inner brake pad via the threaded tubes and
the punches . The brake pad is pushed against the
brake disc when this happens. The reaction force which
now arises on the brake calliper is transferred to the op-
posite brake pad by means of the sliding seat, so that the
opposite pad is also pressed against the brake disc with
the same force. When the brake pressure is reduced, the
spring force returns the bridge , the threaded tubes and
lever to the starting position.

- Fewer bolted connection points
- Easily accessible bolted connection points

Electronic safety systems for your brakes. It comes down to the right brake compatibility.
Over the past few years, disc brakes and electronically controlled brake systems have become established in com-
mercial vehicle technology. Here, systems such as ABS and EBS are leading to new possible combinations and
interfaces between the towing vehicle and the trailer. Having the right brake compatibility is decisive when it comes
to achieving the best braking results. The experts at BPW will be happy to advise you and recommend the optimum
solution for your applications.
In practice, the following issues are apparent:
Drum or disc brakes are used both on the tractor unit and on
the trailer. Disc brakes perform their braking function even at
very high temperatures (low fading) and respond with dispro-
portionate wear when they are overloaded (a situation which
is not apparent to the driver).
Trailers can be operated with dedicated tractor units or they
can be used with many different tractor units.
Tractor units with or without EBS are used. Tractor units
with EBS have coupling force control and are responsible
for brake force distribution in accordance with the ECE-R 13
brake directive. The electronically controlled brake system
senses the braking characteristics of the trailer and automat-
ically adapts the tractor unit’s braking effort. Thus, in theory,
each component of the tractor/trailer combination provides
a braking effort in proportion to its own mass. The result-
ing dynamic properties of the tractor/trailer unit cannot be
reproduced on the roller test rig because only one axle can
be tested in this case.
Adapter valves are used in some cases in trail-
ers and semitrailers with disc brake axles, or
are included in the homologation of the trailer.
These valves deliberately hold the service brakes back in
the low pressure range, in order to compensate for the bet-
ter response of the disc brake. Modern tractor vehicles with
EBS detect this restraint in the trailer’s braking characteris-
tics. This procedure is misinterpreted as poor braking effort
and the braking pressure in the trailer is increased across
the entire pressure range. This means the trailer tends to be
over-braked. An adjustment valve is required in all markets
where there is potential for a mismatch between tractor and
trailer and the trailer is predominantly towed by tractor vehi-
cles without EBS control.
Just these few points should indicate how important it
is to match tractor with trailer. It is not something that
can be disregarded in order to save cost. Rather it must
become part of everyday workshop practice. If compat-
ibility is neglected, damage may occur as a direct result
of inadequate brake equalisation and not as result of de-
fective components.

Strengths of disc brakes: - Very good brake force modulation - Low fading- High braking comfort
(rapid response times) - Low weight
Strengths of drum brakes: - Mature, robust technology - Low susceptibility to dirt because of
enclosed design - Low heat transfer to the adjacent
components (e.g. bearings, tyres) - Rapid brake service thanks to
BPW’s patented ECO principle - Good integration into the vehicle (space)
Disc brakes for zero offset wheels have a lighter system weight than 120 offset wheels, and do not wear so much since the temperature during braking is lower.
Wider track and spring centres are possible with 120 offset – only one spare wheel is needed for the towing vehicle and trailer, depending on the version
Brake matching between the tractor unit and the trailer is essential to ensure optimum performance and a longer brake service life
In general, disc brakes offer excellent braking performance. If trailers and semi-trailers are towed by tractor vehicles which
- do not have a secondary braking system (retarder, Intarder, engine brake, etc.) and/or
- are equipped with a trailer parking brake valve (anti-jackknife brake)
then the brake pad wear can be expected to be disproportionately greater than on a comparable drum brake!

The power plant for your brake system. Brake cylinders from BPW.
In a brake system, it is of the utmost importance to achieve an optimum interplay between the individual compo-
nents. The brake cylinders have a decisive role to play in this, because they have to provide a perfectly modulated
force transfer within the brake system. BPW develops and produces its own brake cylinders for drum and disc
brakes – further proof of our extensive expertise when it comes to brakes. As a system supplier, our product range
includes diaphragm and spring-type cylinders.
Function of the service brake: As soon as the com-
pressed air acts on the diaphragm , the force generated
(area x pressure) acts on the flange and the push rod .
The force is transferred to the wheel brake in accordance
with the brake pressure applied. When the brake cylinder is
vented, the compression spring moves the flange with
the push rod and the diaphragm back to their starting
positions.
Function of the parking brake: When the pressure level in
the brake system (reservoir tank) drops close to zero, the
parking brake is activated in vehicles with spring-type brake
systems. The spring-type actuator applies the wheel brake
by means of the cylinder push rod and the integrated high-
performance spring , thereby preventing the vehicle from
rolling away. When the release pressure is reached, the high-
performance spring in the spring-type actuator is com-
pressed by the diaphragm and the flange. The pressure
acting on the cylinder push rod drops until the brake is
released. The parking brake is now inactive and there is noth-
ing more to prevent the vehicle from being driven.
59
Refer to the BPW brake cylinder booklet (BPW-BZ-…) for more technical data. They can be supplied fully fitted to BPW axles as initial equipment.If the lever length is > 150 mm, make sure that only long-stroke diaphragm cylinders are used. Always use long-stroke cylinders with automatic slack adjusters.
Delivery variants of BPW brake cylinders
Diaphragm cylindersThey act as a service brake and are characte-rised by their compact external dimensions and low weight.
Diaphragm-diagram (M-M) cylindersThey act both as a service brake as well as an auxiliary and parking brake. They are lighter than the diaphragm-piston cylinder.
Diaphragm-piston (M-K) cylindersThey have the same function as a diaphragm-diaphragm cylinder. Their greater spring-type accumulator force means they are suited above all for vehicles with higher axle loads and limited installation space.

The BPW Brake Monitor is a brake pad/lining wear indicator that informs you about the current status of the brake
pads/linings at any time. This means you can refer to the BPW Brake Monitor in good time to read off when the
brake pads/linings need to be changed. This provides reliable protection against catastrophic brake failure and re-
presents a good example of how we are comprehensively progressing with brake technology development, thereby
securing decisive benefits for our customers.
BPW Brake Monitor. Early warning system for disc brake pads and drum brake linings.
Function: With the BPW Brake Monitor retrofit kit for disc
and drum brakes, you can check your vehicle on the display
module at any time to see if the wear limit has been reached.
The “SERVICE” indicator changes to red as soon as any of
the brake pads/linings is down to only the minimum thick-
ness. In applications with disc brakes, the yellow “WARN-
ING” LED flashes first as soon as only one of the brake pads/
linings has worn down by approx. 80%. The red “SERVICE”
indicator remains visible even if you have parked the vehi-
cle and there is no electrical power supply to the trailer. This
means you can still tell if the wear limit has been reached on
at least one brake pad/lining. In this case, you should change
the brake pads/linings as soon as possible.
Wear sensorReliable technology that detects when the brake pads/linings have reached their wear limit.
Brake MonitorThe data measured by the wear sensor is transmitted to the Brake Monitor which provides a warning in good time that the next service is due.

Axle involvement
No roads are absolutely smooth. To make up for this, we build absolutely perfect running gear.
A running gear system is only ever as good as its suspension. BPW air suspension systems are individually de-
signed to cope with where and for what they’re going to be used, and what load they’re going to carry. Only in this
way it is possible to ensure the optimum driving safety at the same time as reducing the stress on the driver, the
cargo and the body. This reduces wear on the tyres and cuts down the stress on the vehicle body and the cargo –
as well as reducing your expenses. Another advantage: The modular construction means that it’s easy to exchange
individual components in the event of a repair.
Function: The principle components of a BPW suspension
system are air suspension hanger brackets , shock absorb-
ers , trailing arms , air bags and the axle involvement .
The trailing arms are firmly jointed to the axle via the axle
connection and are mounted so they can rotate in the air
suspension hanger brackets which are fixed to the frame.
This unit comprising an axle and trailing arms is braced on the
vehicle frame via the air bags . The air bags perform the
suspension function. The pressure in the air bags required for
supporting the body is set automatically depending on the
state of load. This automatic pressure adaptation guarantees
a consistently high level of driving comfort and low body vi-
brations in all load conditions. The shock absorbers guar-
antee optimum damping of the body vibrations, and there-
fore constant roadholding by the wheels and little tyre wear.
This can be reduced even further when driving unladen, by
using an axle lift .

Air suspension has come to the fore in the transport
business. In comparison to leaf suspension, it offers:
High level of driving comfort in all load conditions
Long suspension travel
Increased road safety (e.g. by high rolling stiffness)
Lower weight
Optimum use of the permitted vehicle height
Manually controllable raising and lowering of the super-
structure
Greater precision in brake control via load-dependent bag

Static and dynamic axle load equalisation
Load-dependent damping (PDC) as an option
The possibility of using an axle lift
The U-shaped connection comprising the axle and fl exible trailing arms noticeably reduces unwanted rolling movements and reduces the load on the vehicle frame. This principle of connecting the axle and trailing arms together acts as a stabiliser to cut down rolling movements. In this way, air-sprung suspension systems from BPW achieve safe driving properties as well as a high level of driving comfort.
The trailing arm connects the axle to the vehicle frame via the air suspen-sion hanger brackets and the air bag. BPW trailing arms (single or twin leaf springs) are highly fl exible spring steel elements. They are hot-rolledfrom one piece, after which they are shot-peened and cataphoretic dip-coating and zinc-phosphating.Trailing arms absorb a great deal of torsional forces applied to the axle beam. Various trailing arm versions permit individual equalisation – for example for axle load, track, spring centre, centre of gravity height and driving comfort. In every situation, their stiffness and fl exibility are exactly matched to the vehicle and its application. This reduces the stress on the body and ensures that the vehicle achieves a long service life. The catch plate offers the necessary safety reserves if the worst should come to the worst. Long-life steel-rubber-steel bushes (up to 4 times the service life of rubber-steel bushes) offer maintenance-free mounting of the trailing arm. The axle is exactly controlled, while tyre wear and operating costs are both reduced.

Air suspension hanger brackets transfer all control, braking and accel-eration forces from the axle to the vehicle frame. Short, adjustable BPW air suspension hanger brackets with integrated shock absorber mounts make installation easier, reduce weight and cut the torsional load on the vehicle’s frame. The vehicle manufacturer benefits from straightforward cross-bracing options at the interface between the frame and the hanger bracket. Rapid unit alignment is possible using BPW hanger brackets with integrated track setting. Production tolerances on the vehicle can be equal-ised or wheelbases corrected without the need to unfasten the U-bolts (axle tracking).
BPW air suspension hanger brackets are available in steel as well as in high-grade steel and aluminium on request.
What is more, with the bolted Airlight II air suspension hanger bracket, BPW is offering manufacturers the opportunity of coating vehicle frames without air suspension hanger brackets, and not connecting them to the complete axle unit until the final assembly stage. Cold joining technology allows the bolt-on hanger bracket to be mounted on standard frames, including aluminium frames, with bottom boom width as little as 120 mm – no changes are necessary on the frame.
66
Lack of driving comfort increases the strain on the driver, the vehicle and the cargo. BPW finds the solution to this in the air.
The shock absorber reduces vibration in the vehicle body and ensures greater driving comfort and road safety. That’s because the wheels stay in contact with the road and dynamic wheel load fluctuations are reduced.BPW uses various types of shock absorber to guarantee the best possible damping in each case. High-volume BPW shock absorbers are adapted to the vehicle, the overall height and the range of applications. The rub-ber bushes of BPW shock absorbers can be replaced. This is much less expensive than buying a new shock absorber.
The axle is connected to the trailing arm using the axle connection com-prising: spring plates, spring pads, segments and U-bolts. Clamped, pos-itive-locking axle connections ensure an even force transfer into the axle appropriate to the degree of load. This is only possible with square axle beams which therefore offer a long service life. The connection parts are attached at the reinforced radii of the axle beam (no welded connection). BPW uses U-bellows because of their spring characteristics. They roll over the rolling piston during compression.

The air bag ensures outstanding suspension of the body and makes it possible to adjust the vehicle height using the „lifting“ and „lowering“ functions.
BPW air bags are firmly rolled into the mounting plate at the top while they are bonded onto the clamping plate at the bottom by vul-canisation, which means they are guaranteed to be air-tight. The rolling piston is made from glass-fibre reinforced plastic with a steel support to give reduced weight and resistance to corrosion. The integrated bump stop protects against damage when the bags are vented. BPW offers air bags for any application (total spring travel up to 450 mm).

Function of air suspension installation:
The ride height is controlled automatically by a height con-
troller referred to as the air suspension valve . If a cargo
load is applied to the vehicle or its suspension is compressed
with the result that the actual ride height (distance between
the axle midpoint and the bottom edge of the vehicle frame)
becomes less than the set ride height, then compressed air
from the reservoir is transferred into the air bags until
the required ride height is once again reached. On the other
hand, air is vented from the air bags if the cargo load is re-
moved from the vehicle or its suspension rebounds with the
result that the actual ride height is greater than the set ride
height. This venting continues until the required ride height is
once again reached. As a result, the air suspension system
sets the ride height to a standard level irrespective of load-
ing condition of the vehicle. This level can be set as required
within a certain range. The body height can be infinitely varied
using a lifting and lowering device when loading and unload-
ing the vehicle at a loading ramp. A rotary disc valve is used
for this purpose. It is manually operated and either causes air
to be pumped into the air bags or vented from them in order
to adapt the air suspension to the loading ramp height. A
lifting and lowering device is also the precondition for trans-
porting interchangeable tank bodies. These can be picked
up or dropped off without additional equipment thanks to the
air suspension. The air suspension can be activated both us-
ing conventional mechanical valves and an electronic control
system.To achieve optimum function and the greatest possi-
ble road safety, particularly in critical situations, we expressly
recommend using dual-circuit air suspension installations
with a transverse throttle.

Airlight II air suspension.The highlight for BPW running gear.
Airlight II air suspension sets the standards in running gear technology. With its modular structure, short installation
times and adjustable air suspension hanger brackets as standard, Airlight II shows just how ingenious and eco-
nomical it is. Fully installed with a clamped axle connection, it is maintenance-free in on-road applications. The M 24
spring bolt is a new feature that replaces the M 30 spring bolt, thereby offering extra safety because it increases the
size of the contact surfaces at the same time. Furthermore, with the bolt-on Airlight II air suspension hanger bracket,
BPW is offering more flexibility in production because it can be connected subsequently to the vehicle frame with
the axle unit using cold-joining technology.

Function: In conventional air suspen-
sion, the axle load is directed into the
vehicle frame partly through the air bag
and partly through the hanger bracket,
depending on the lever arm lengths. In
the BPW Airlight Direct air suspension
system, however, the air bag is located
directly over the axle. This means it
can cushion the entire axle load. This
adds up to comfortable suspension
combined with low vehicle floor accel-
eration values.

Axle lifts from BPW. The device for a long tyre life.
As an option, multi-axle vehicles can be equipped with an axle lift to reduce the wear on the tyres when driving
unladen or with a light cargo. BPW offers axle lifts for positioning in the middle or at the sides. All BPW axle lifts are
compatible with the Auto-Drop system. It automatically lifts up to two axles on a tri-axle suspension (when unladen)
and lowers them again (when laden).
BPW axle lifts – Features and benefits!Reduced tyre wear
Low inherent weight
Moving-off aid for increased traction on the driven axle
Compatible with Auto-Drop system (automa-tic lifting and lowering)
Double-sided axle lift:
– Robust design with proven brake cylinders
– Installation without welding work (also for retrofitting)
Metal surfaces with cataphoretic dip-coating and zinc-phosphating (KTLZn)

Cataphoretic dip-coating and zinc-phosphating (KTLZn) (page 13)
Locating the axle lift at the side is recommended for lifting the
first axle and in vehicles with limited ground clearance, high
axle loads or long suspension travel. The double-sided lift
(for air-sprung axles up to 12 tonnes) does not need any space
in front of the air suspension hanger brackets or in the middle
of the vehicle. It can be fitted at any time to any axle posi-
tion offering the convincing benefits of low weight and good
ground clearance. Both the central axle lift device using a
lifting bag and the BPW central lift with bellows fitted in the
middle of the vehicle can lift one or more suspension axles and
are integrated within the space of the axle unit. Their compact
design means they are preferred for use in vehicles with limited
ground clearance and small tyres (e.g. pallet box trailers with
single tyres).

BPW PDC shock absorber.Intelligent damping that automatically detects the loading condition.
The best damping, better road safety, lower maintenance costs: The BPW PDC shock absorber (PDC = Pneumatic
Damping Control) improves driving properties and driving comfort because it adjusts continuously to the particular
loading condition. An intelligent solution that can be OEM-fitted or retrofitted to BPW air suspension systems.
Function: The disadvantage with conventional shock ab-
sorbers is that their characteristics can only be optimally
adapted to one loading condition (usually fully laden). The
PDC shock absorber detects the actual loading condi-
tion via the air suspension and adapts itself smoothly.
This improves driving safety at the same time as reduc-
ing the strain on the chassis and the vehicle, in par-
ticular when the trailer is empty or only partly laden.
The PDC shock absorber is almost essential in high-value
vehicles and when carrying sensitive cargoes. Vehicle main-
tenance costs are reduced. The cargo and the carriageway
are also subjected to fewer shock loads. The PDC shock ab-
sorber is connected to the BPW air suspension system and
does not require any electronic control systems.
The channel crossmember: Vehicle manufacturers all over the world quickly appreciate the assembly benefits of this component. Whether it’s the hanger brackets, the shock absorber attachments or the cross-braces, everything is integrated to save space. Even steering axles can be connected to it without additional preparation. The channel crossmember is available in two versions – with an open, narrow hanger bracket for welding or with a cover plate for bolting/riveting onto the vehicle frame. The channel crossmember can even make additional crossmember un-necessary, depending on the frame design.
3-D trailing arms: The ingenious „three-dimensional trailing arm“ (3-D) enables vehicle manufacturers to assamble air-sprung tri-axle suspen-sion systems with an LL self-steering axle onto the same frame as a rigid unit without any problems – there’s no need to have a special offset frame. It goes without saying that the 3-D trailing arm offers the same functions and quality features as BPW trailing arms for rigid axles.
BPW channel crossmember – Features and benefits!Optimum support for the force application into the vehicle frame
Reducing the stress on the frame construc-tion (lower stress)
Possibility of adapting to installation and service units (brake, air suspension)
Simple installation on the vehicle frame, optimised for production
Increased payload by lightweight construc-tion (e.g. perforated C-section)

No creases when you are on the move.With the Combi airbag from BPW.
In road/rail/ship combined transport, trailers with vented air suspension systems are lifted by gantry cranes or ma-
noeuvred by marshalling tractors. Conventional air suspension systems are at risk of damage to their air bags. The
patented Combi airbag from BPW (European patent 0 554 573 B1) provides an effective safeguard against folding
and creasing of the air bag and thereby guarantees a long service life.
Function: The air bag of a Combi airbag is divided into two
parts: The air bag is bolted onto the vehicle frame with the
rolling piston while the centring cone is connected to the
trailing arm. When the trailer is lifted, the axle and the cone
move downwards. The movement is restricted by the shock
absorbers. However, the airbag remains in its rest position.
When the trailer is lowered to the ground, the airbag and cen-
tring cone once more come together. The bag can neither
fold nor crease. A long service life is thus assured.

BPW VB suspension units. Indestructible leaf suspension units for trailers and semitrailers.
Whether on- or off-road local or long-distance – you can rely 100% on BPW leaf suspension systems. They are
extremely robust and can master even the most exacting challenges. Their simple design means they are also easy
to repair when the infrastructure is poor. At the same time, axle loads of 9 t and more pose no problems for our VB
units.
Function: BPW VB suspension units are equipped with
parabolic or multi-leaf springs . Depending on the ver-
sion, parabolic springs have two or three parabolic rolled
spring layers. The efficient use of material enables them to
combine low weight with a low height. Multi-leaf springs
(trapezoidal springs) contain a stack of spring layers with a
constant cross section and graded lengths to give a trapezoi-
dal shape. They are characterised by their robustness and
good default driving properties as well as the ease of replac-
ing individual spring layers. The ends of the leaf springs are
mounted on sliding bearings using spring slides both in
the connecting pieces and in the equalising beams . This
allows the spring pack to increase in length without obstruc-
tion when the suspension deflects. Axle control is handled
by separate torque arms which can be adjusted on one
side to enable the tracking to be set easily. In the case of
multi-axle suspension units, the middle connecting pieces
have pivoting equalising beams . The spring ends slide-
mounted in the equalising beams together achieve static axle
equalisation (even distribution of axle load when stationary
and on the move). The design means that no dynamic axle
load equalisation is provided (uneven axle load distribution
when braking). BPW leaf suspension systems are designed
to offer „self-damping“ and do not need any additional shock
absorbers.

BPW W suspension units. Built for tough applications in extreme climatic zones.
The robust and long-lasting multiple leaf spring suspension systems in BPW units master even the harshest conditions.
On roads, tracks or construction sites, in the icy Arctic or the tropical jungle – W suspension units have been de-
signed for tandem axles and provide for reliable goods transport even under the most difficult conditions.
Function: Whenever you need the ruggedness to cope with
high axle loads under difficult operating conditions, choose
leaf-sprung tandem axle units with an intermediate pivoting
trunnion axle for holding the frame support brackets. The
spring packs are extremely sturdy and comprise several
spring steel layers. They are mounted in swinging bearings
on the trunnion axle using bronze bushes. The rigid axles
are clamped onto the spring ends and are controlled by
the offset main spring layers . An even distribution of ten-
sion across the length of the spring is achieved thanks to the
use of spring layers with different lengths. This produces a
trapezoidal shape in the side view, which explains why the
arrangement is also referred to as a trapezoidal spring. Two
low supports between the springs are used for attachment
below the vehicle, or a tall central block provides for direct
mounting on the vehicle frame.

The culmination of more than a century of expertise in running gear. Engineering services from BPW.
BPW helps you to get your vehicle on the road in the best possible condition. With numerous engineering services
that put your individual trailer requirement profile into the focus of attention. Whether FEM or brake measurements,
whether driving tests or test facility trials and tilting stability calculations – our specialists advise you in detail and
develop the solution that best meets your needs.
FEM calculations
BPW possesses many years of experience in performing
stress measurements during driving trials. We perform com-
puter analysis (also on the vehicle frame or frame compo-
nents) and propose any necessary optimisation measures.
In this way, you cut calculation time as well as shortening
testing and development cycles.
Application consulting
BPW assists you in standardising vehicle frames and helps
you to select axles and axle units which are appropriate for a
particular market or application. With BPW, your ideas are in
the best hands. That’s because BPW offers you a wide range
of ingenious solutions for technical applications. Whether
you have detailed questions or want to develop complete ve-
hicles: We are happy to offer you advice. If necessary, BPW
can also test vehicles in operation so as to come up with
the correct solution for you based on the measured data. In
this case, BPW refers to existing standards and uses its own
experience, or else develops a special catalogue for you con-
taining the necessary measures.
Driving tests
In driving tests, BPW analyses the load on frame compo-
nents: deformation or stress on connecting pieces, gus-
set plates and crossmembers is recorded using strain
gauges and evaluated with the vehicle manufacturer.
This means frame and chassis components can be optimally
designed prior to the start of volume production.
99
Test facility trials
In BPW test facility trials, components are subjected to pul-
sating or alternating forces. Various test programmes can be
used for this, such as driving along a test route. As a result,
operational strength and component flexibility can be tested
under realistic conditions. This reduces the development
time of components and modules.
Modular test rig
Using the 12-channel modular test rig, BPW can simulate all
vertical, transverse and longitudinal forces as well as brak-
ing, steering and pitching torques that can act on the running
gear during operation. As a result, off-road tracks can be
simulated in real time and test track drives can be reduced.
Also, the inspections are rendered more reproducible.
Brake calculations
BPW prepares EC/ECE brake calculations on the basis of
BPW brake cylinders as well as components and designs
from other manufacturers. In this way, design tolerances can
be exploited sensibly in terms of technology and efficiency.
The best possible brake suite and the most effective braking
for your vehicle are assured.
Turning circle and tilting stability calculations
BPW offers you the service of EC-licensed turning circle cal-
culations. This calculation is accepted for the vehicle regis-
tration and therefore replaces the practical demonstration in
almost all cases. Also, the planned vehicle will comply with
statutory provisions right from the start. Since July 2003, the
rollover resistance of hazchem vehicles will have to be dem-
onstrated as part of the registration process. An acceleration
at right angles of 0.4 g is demanded. This has to be con-
firmed mathematically or using the tilting test. BPW offers
you a mathematical check of compliance with this require-
ment. It is performed in accordance with ECE regulation no.
111, appendix 4. As a result, the costly tilting test can be
avoided.

We offer you more than just in time. Individual BPW logistics concepts.
Greater availability, less fuss, more efficiency. At the end of the day, this is what the ingenious BPW logistics con-
cept offers you. With a personal contact and solutions that are tailor-made to your individual requirements. This is
all based on the BPW logistics centre that supply you with components not only at the right time but also ready to
install straight away. At the same time, you can reduce your warehouse capacities.
101
Service and Distribution / Logistics concepts
Global spare parts provision
BPW stocks about 7500 different spare parts in its logistics
centre. Our customers can order parts on a 24/7 basis. In
Germany, orders for goods weighing up to max. 120 kg re-
ceived from Monday to Thursday up to 6:00 p.m. and Friday
up to 5:00 p.m. will be delivered to the customer by 8:00 a.m.
on the next morning. In emergencies, orders can be made
ready for collection at night and on weekends. As a result,
even customers who carry little stock are able to respond
rapidly.
Delivery performance
Intelligent logistics combined with ground-breaking ware-
house technology, powerful IT systems and a lean produc-
tion process make BPW a highly reliable logistics partner with
short response times. And you will meet the requirements for
goods streams with critical timing.
„All inclusive“ logistical care
From order acceptance through to delivery, you will be dealt
with by one contact. He or she will take down your require-
ments and process the order in a friendly and cooperative
manner. For you, this means quick decision-making and
clearly defined responsibilities.
Intelligent packaging solutions
The transport racks developed by the BPW Logistics Centre
for air suspension modules permit them to be transported
without damage to our customers’ production sites and
reduce the handling times there. Our specially developed
packaging for overseas deliveries complies with the strictest
import regulations (e.g. Australia and China). Empty contain-
ers can be stacked compactly and so returned inexpensively
for reuse, or else they can be disposed of in an environmen-
tally friendly manner.
Customer-specific logistical support
In cooperation with the customer, we develop logistical con-
cepts with the objective or reducing stock, cutting response
times and therefore saving costs. The principal objective is
to reach the best solution for both parties. In this respect, we
have already prepared logistical concepts on the basis of the
Kanban system and have implemented just-in-time deliver-
ies. As well as an outstanding technical product, BPW there-
fore offers you hybrid solutions which are also demonstrated
by our high-performance, innovative logistics.
Prefabrication
Thanks to the BPW Logistics Centre, it is possible to prefab-
ricate and dispatch deliveries to customers; this means cus-
tomers will receive modules comprising more than the BPW
product range (e.g. vehicle lighting, tyres or steel wheels).
And you will receive all your orders ready for production, from
a single source.

Every BPW axle has a type plate. It is affixed on the centre of the axle beam, facing to the rear of the vehicle. The
information on the type plate enables you to order replacements for wearing parts at any time or – after an accident,
for instance – the entire axle.
The BPW type plate.Your axle‘s identity document.
The BPW type name (see axle type) is composed of a letter
group and a number group. The letter group identifies the
type of axle and suspension version as well as defining the
hub version. The number group specifies the axle load on
the ground in kilograms and the number of wheel studs per
wheel hub (for disc wheel connection).
The expanded test report line (second line) not only contains
the standard test report but also any special test reports for
other test loads. Up to 3 test reports are possible depend-
ing on the wheel brake. The barcode used has the standard
format code 39 and can be read using any barcode scanner
normally encountered in the industry. The left barcode con-
tains the date of manufacture and number of the axle (e.g.
064940189), the right barcode contains the corresponding
BPW code number (e.g. 27.48.613.136). The brake test report
specified on the type plate can be downloaded from the BPW
website at www.bpw.de (Download Centre - Test Reports). All
BPW components and assemblies have a 10-digit “speaking”
code number.

With BPW, everything is in the right place.This means things that belong together fit together.
In drum braked axles from BPW, the air cylinder brackets are welded onto the axle beam. They are used for ac-
commodating diaphragm and spring-type cylinders. The offset hole pattern of the BPW air cylinder bracket permits
optimum positioning of the brake cylinder for any lever length. In addition, the air cylinder brackets have marks for
additional hole patterns when using small brake cylinders with narrower stud spacings. Dirt, water and snow can
escape through a gap between the air cylinder bracket and axle beam.

Withstand any pressure.With air bags from BPW.
BPW air bags are firmly rolled into the top air bag mounting plate and are clinched onto the clamping plate at the
bottom by vulcanisation. The top air bag cover is either bolted directly onto the frame or a plate or bracket is welded
onto the vehicle frame to attach the bag, depending on the bag version. The air bag mounting plate is bolted onto
it using two M12 securing nuts. The air bag piston at the bottom is bolted onto the trailing arm using two M16
securing bolts.

With bracketIn the air bag with an offset, the bracket
welded onto the top plate is welded
onto the frame and bolted onto the bag
mounting plate. The 60 mm tall bracket
can also be supplied in aluminium. The
maximum lateral offset between the top
and bottom attachment must not ex-
ceed 10 mm. The top and bottom bag
attachments must not be installed with
any rotational misalignment.
General informationTorsional forces are created in air
bags with an offset. These forc-
es must be absorbed by gus-
set plates welded onto the frame.
When the structure and the bag offset
are being defined, it is necessary to
ensure that the air bag has sufficient
clearance.

BPW supplies the air installation kit and the corresponding installation diagram for the particular application. The
installation diagrams show the valves in what is referred to as the ISO view. The letters and numbers of the valves
printed inside boxes on the installation diagrams are identical to the markings on the valves themselves. That makes
installation very straightforward. BPW‘s warranty will be invalidated if installation is performed incorrectly by third
parties.
BPW makes it easy for you.Air suspension installation exactly according to plan.
Example for air suspension installation: Tri-axle suspension, without lifting and lowering, with axle lift device and LL self-steering axle.

The air suspension valve is the heart of the air suspension
installation. It controls the air bag pressure according to the
vehicle load and therefore keeps the ride height constant.
It is attached in the vehicle frame and connected to the axle
by means of the linkage device – in the centre of the middle
axle in tri-axle suspension systems or of the rear axle in tan-
dem axle suspension systems. In special cases (e.g. axle lift
device), the air suspension valve can also be connected to
the front or rear axle.
Stroke limitingcatch straps
Air suspension valve
The valve lever is horizontal in the driving position. It is moved down-wards for a functional check. The air now flows out into the atmosphere via the vent flap. However, the valve shaft must be turned through 180° if air gets into the bellows. The valve lever must be installed the other way round for this. The ride height must be set on level ground by moving the articulated rod in the rubber joints and adjusting on the lock nuts.
Rapid ventingIn vehicles whose payloads are unloaded rapidly, e.g. tippers, container vehicles, steel strip vehicles, etc., stroke limiting is required in the form of catch straps or rapid venting of the air bags.
1. Stroke limiting is performed using an air suspension valve with inte-grated shut-off or by a separate shut-off valve. The shut-off valve is bolted onto the vehicle frame and is connected to the axle by means of a return spring hooked onto the draw pin. Once the maximum stroke height has been reached, the air supply to the air bags is blocked there-by limiting the stroke.
2. Stroke limiting can also be performed using catch straps. When install-ing, make sure the catch strap does not chafe on the axle beam.
Crane, rail or ship transportIn vehicles for crane, rail or ship transport, BPW recommends air bags with a split piston – the Combi Airbag II system. No stroke limiting is re-quired when the combination air bag is used, providing stroke limiting is not expressly stipulated in the technical documents.
Depending on the version, the limiting function is in the shock absorb-ers in axles with a lifting and lowering device without stroke limiting by shut-off valves or catch straps. The shock absorbers are equipped with a traction stop, however they are not designed for stop forces from approx. 8.5 bar air bag force.

To light axles and reduce costs.With BPW axle light devices.
Axle light devices spare tyres in unloaded or low loaded condition and additionally save fuel and therefore cash,
thanks to the low rolling resistance along the road. At tandem axle suspensions one axle an be lifted , at tri-axle
suspension maximal two axles can be lifted.
With steering axle
A „rigid axle/steering axle“ ratio of 1:1 is permitted in vehicles
with series LL self-steering axles. As a result, one rigid axle
can also be lifted in tri-axle suspension systems. It is ad-
vantageous to lift the first suspension axles since this gives
greater ground clearance (body lean) and a longer wheel-
base – thereby achieving a more stable driving behaviour.
The statutory regulations of the German „BO-Kraftkreis“ –
defining a turning corridor within which the vehicle must stay
when driving in a circle – this must be adhered to!
Control
Lifting axles are controlled either electro-pneumatically (elec-
tric switch), with manual pneumatic control (hand-operated
valve) or automatically (compact valve). The overload protec-
tion demanded in the legislation is taken into account in the
BPW installation kit.
141
The stroke of the lifting axle corresponds to the upward travel
of the axle. The clearance under the tyre is reduced when the
other tyres move upwards. In air suspension systems with
an axle lift device, the ride height must be set to a minimum
upward travel of approx. 100 mm. A working cylinder can
be installed on the air suspension valve if it is not possible
to set the ride height for the minimum upward travel. When
the lifting device is operated, air is admitted into the working
cylinder and the ride height is automatically increased by ap-
prox. 40 mm. Note the overall height of the vehicle!

Two-sided lift
The double-sided axle lift is equally suited to air-sprung axles
(up to 12 t) with disc and drum brakes. It is mounted below
both air suspension hanger brackets on each module and
is therefore located within the suspension clearance. This
means it does not collide with the vehicle equipment such
as pallet boxes.
Lateral arrangement
The lateral arrangement is suitable for lifting the first suspen-
sion axle when the axle weights are relatively high or in the
case of long-travel suspension units. The lift arm is mounted
on the front air suspension hanger bracket below the trailing
arm. The lift bag is located centrally on the lift arm (V =
0 mm) and is attached below the longitudinal member of the
vehicle. No additional crossmembers are required. The top
lift bag cover can also be offset ±20 mm to the side.
Rubber bump stop
143
Central liftCentral arrangement
The central lift represents another variant for lifting the middle
(rear) axle unit or if there is little space available. It is attached
in the centre of the axle to a crossmember in the frame and
is bolted onto the axle. The lift bag forces must be absorbed
by crossmembers of sufficient size.
The lifting device can be arranged in the centre of the axle for
lifting the middle (rear) suspension axle or if space is limited.
This axle lift device is attached to the frame using an addi-
tional bracket in the middle of the vehicle. Refer to the techni-
cal documents to see the installation position of the bracket.
The lift bag forces must be absorbed by a crossmember.
