This section describes the operation of pump, motor, gearbox and controller to drive the transit mixer drum in an electrical closed loop control system. It is a useful reference for readers, which are not familiar with the functioning of transit mixer drive systems.

The variable displacement pump TMP is designed to convert a mechanical input power into hydraulic power. The input shaft, driven by the engine PTO, turns the pump cylinder block, which contains a ring of pistons. The pistons run against a tilted plate, called swash plate. This causes the pistons to compress the hydraulic fl uid, which imparts the input energy into hydraulic fl uid. The high-pressure fl uid is then ported out to provide the hydraulic pressure and fl ow to the fi xed displacement motor TMM.The swash plate angle can be varied by the actuating piston via the electrical propor-tional control valves depending on the current value, which is generated by the TME controller.

CHARGE PUMP The charge pump is necessary to compensate internal leakages and supply cool fl uid to the system, to maintain positive pressure in the main system loop, as well as pressure to operate the control system. Charge pressure must be at its specifi ed pressure under all conditions of acceleration and deceleration of the drum to prevent damage to the transmission.The charge pump is a fi xed-displacement, gerotor type pump integral in the variable displacement pump and driven by the main shaft.A charge pressure relief valve limits charge pressure.

CHARGE RELIEF VALVE

MULTI-FUNCTION VALVE The multi-function valve incorporate the system check valve and also the high-pressure relief valve function. The system check valves allow pressurized fl ow from the charge pump to enter the low-pressure side of the loop whenever system pressure dips below a certain level. Two system check valves are used to direct the charge fl ow into the low-pressure side of the closed circuit system.The high-pressure relief valves are designed as direct operating poppet valve, which are a fi xed setting for differential pressure of 420 bar [6090 psi]. If the pressure reachs the setting value the valve will be open immediately by cross-porting the system fl ow to the low-pressure side of the closed circuit system.

The charge pressure relief valve on the charge pump serves to maintain charge pressure at a designated level. A direct-acting poppet valve relieves charge pressure whenever it surpasses a certain level which is nominally set at zero fl ow, means in neutral position. The setting level is specifi ed on the model code.

TRANSITMIXER MOTOR – TMM

The fi xed displacement motor TMM is designed to convert an input of hydraulic power into a mechanical torque and speed output power. The high-pressure hydraulic fl uid enters through the input port. The fl uid pressure builds behind the piston causing them to move down the swash plate. As the pistons returns up the swash plate again, the fl uid is allowed to exit through the exit port. The spinning pistons are housed in a cylinder bloc, which is connected to the output shaft.The mechanical output is used to turn the gearbox TMG.

LOOP FLUSHING DEVICE The integrated loop-fl ushing device in the motor is used to fl ush out a certain oil fl ow from the closed circuit system for cooling.The orifi ce loop fl ushing valve defi nes a fi xed fl ow value from the closed circuit system on the low-pressure side only when there is a pressure differential in the main loop. The spring centered loop fl ushing shuttle spool, controlled through the high-pressure side, provides a circuit between the low-pressure side of the closed loop and the orifi ce loop-fl ushing valve. At the time of fi rst operation a rapid air separation from the closed circuit is also achieved by the fl ushing device and in addition, it is ensured that unavoidable “installa-tion dirt“ is fl ushed out at the same time and can be picked up by the suction fi ltering

TRANSITMIXER GEARBOX – TMG

The two-stage planetary gearbox has to turn and to carry one side of the drum of transit mixer. It is assembled to the mixer frame of base supports, which also carry the torque force of the drive. It also provides the option to carry a water tank which is located in the upper part of the housing. The dynamic swivel angle of the output/drum fl ange will be compensating for the defl ection of the truck frame mainly under off-road conditions.The optional water pump drive is on the left or right drum fl ange side, if you see from drum fl ange side.

SPEED SENSOR All the available gearboxes TMG‘ s are prepared to offer the required speed sensor option. At the factory an oil-tight cover closes the receiving bore for the speed sensor. The location of the speed sensor at TMG‘ s with water pump drive is dependent on the confi guration - left or right water pump side - of the gearbox. On the right side, the speed sensor will be at the top of the motor, on the left side it is under the motor.

TRANSIT MIXERELECTRONIC – TME

The controller constitutes a ready-to-install, operating unit, in dashboard design. The controller is available as a remote and cab mounted controller to supply the electrical pump control. The cab unit is an additional slave device and can be operated only in con-junction with the remote master unit.Using the rotary switch on the operating unit, the direction and speed rotation of the drum are selected and, corresponding to the position of the rotary switch, a current value is supplied to the electrical pump control. The pump output fl ow, which is estab-lished, determines the reference motor speed at the input of the gearbox.The speed sensor in the gearbox measures the actual speed as feedback for the control-ler. The desired and actual values are compared and the pump fl ow is controlled until both values equal. This is in operation at any selected drum speed. With the yellow touch switch on the remote controller, it is possible to stop and start the drum speed independent of the rotary switch position. In this case, the LED indicates changes from lighted to fl ashes.The yellow touch switch on the cabin controller permits a change over to the remote controller and vice versa. In this mode the cabin LED is off and all operatings are trans-fered to the remote controller. The fl ashing LED indicates “stand by” mode. When moving to the other control station the rotary switch position must be set to neutral. Touching the yellow switch with fl ashing LED will change to full light, which means the controller is switched on.

TRANSIT MIXER DRIVE SYSTEM – TM

In accordance with the rotary switch position on the TME controller unit (13), a current set point is generated and provides to the electrical proportional valve (6) of the TMP main pump (2) with a PWM signal. The necessary control oil supply is provided by the feed circuit of the charge pump (3) and is delivered to the actuating cylinder (7) via the electrical proportional valve (6). Depending on the current value, a proportional actuat-ing pressure is established on the actuating cylinder (7) and therefore a stroke, which adjusts the swash plate angle and defi nes the fl ow delivery of the main pump (2).

Depending on the speed of the pump and displacement, the pump fl ow determines the output speed of the TMM motor (9) as well as the input speed to the TMG gearbox (10). The selected drum speed of the controller keeps the drum speed constant. Independent of the engine speed or charging state.In order to meet the demand for a constant drum speed the actual value is measured via the speed sensor (14) in the TMG gearbox (10) and provided as an input signal to the TME controller unit (13). The electronic device compares the actual value with the pre-selected set point of the drum speed and controls the current to the electrical propor-tional valves (6) which sets the swashplate of the pump to the appropriate fl ow to keep the drum speed constant.The system presented completely meets the demand for a constant drum speed in accordance with the pre-selection on the rotary switch of the TME controller unit.The integrated charge pump (3) supplies the closed circuit via two multi-function valves (5) - feed and high-pressure protection - using cooled (14) and fi ltered (12) oil. The integrated fl ushing device (11) in the TMM motor, comprising an alternating slide and permanently set nozzle fl ushing valve, ensures a defi ned exchange of oil in the closed circuit. The oil led via the cooler (15) is feed in again via the charge pump (3) by means of a suction fi ltering system (12) connected upstream.At the time of fi rst commissioning rapid air separation from the working circuit is also achieved by the fl ushing device (11) and, in addition, it is ensured that unavoidable “installation dirt” is fl ushed out at the same time and can be picked up by the suction fi ltering system (12).

Installation Instructions

GENERAL

MOUNTING THE MOTOR

MOUNTING THESPEED SENSOR

MOUNTING THE PUMP

Prior to the system installation please inspects the units for damage occuring during shipping and handling. Remove plugs and covers just before you start to assemble fi ttings and hoses. Make sure that all the other system components (reservoir, fi ttings, hoses, heat exchanger) are cleaned.

Remove the plastic protective cover on the motor side of the gearbox drive in a sealing of the motor with an O-ring.Case has to be taken that there is no axial load on the pinion with the motor mounting into the gearbox.Fasteners for the motor: 4 bolts M12, grade 8.8, tighten to a torque of 80 Nm [708 lbf•in]Hardened washers (acc. to DIN 6916) are necessary under the bolt heads.

Remove the screw holding the sealed sensor cover plate. Remove the cover plate. Assemble the new O-ring on speed sensor and position into place.

If the pump is driven from the rear of the engine via a joint shaft, case has to be taken that the pump and engine power take off is correctly aligned. This means the joint shaft is exactly in confi guration ‚Z‘ or ‚W‘. A misalignment will reduce the life of both the pump bearings and joint shaft.The pump support must have a solid structure to prevent any unnecessary noise.

Fasteners for the pump: 4 bolts M12, grade 8.8, tighten to a torque of 80 Nm [708 lbf•in].Hardened washers (acc. to DIN 6916) are necessary under the bolt heads (and the nuts if through bolts are used).

New self-sealing screw must be use to fi x the

speed sensor. Tightening torque: 8 ± 2 Nm

[71 ± 18 lbf•in]

MOUNTING THEWATER TANK

Gearbox mounting must be on a solid, distortion free, and fl at support face.Min. tensile strength of material: 400 N/mm² [57 200 psi]Mounting surface roughness average peak-to-valley height: Ra = 3,2 µm in acc. to DIN 4768, part1 Allowable fl atness over the whole mounting area is 0.15 mm [0.006 in].Fasten the gear box foot with 3 bolts M20 (on each side); min. grade10.9; tightening torque 540 Nm [4780 lbf•in] Hardened washers are necessary under the bolt heads (and the nuts if through bolts are used).Mounting plate stops are required to absorb the axial load of the drum when the truck decelerates, so that the bolt force is relieved. Stops should be welded in front of the foot, shown here for a rear discharge truck. Front discharge trucks must have the welded stops on the opposite side.

A water tank with max. 1500 l [396 US gal] volume can be attached to the upper part of the housing.Fasten the water tank with 2 bolts M20 on each side; min. grade 8.8; tightening torque 540 Nm [4780 lbf•in]Hardened washers are necessary under the bolt heads and the nuts:

MOUNTINGCONTROLLER TME

Machine wiring, see guidelines below:

• The wiring must be done according to the connection diagram.• All wires must be protected from mechanical abuse. Wires can be run in fl exible metal

or plastic conduits.• Use 85 °C [185 °F] wire with abrasive resistant insulation. 105 °C [221°F] wire should be

considered near hot surfaces• The minimum wire gage should be 1 mm² [0.002 in2]• Separate high current wires - >0,3 A - such as solenoids, lights, alternator or fuel

pumps from control wires.• Run wires along the inside of, or close to, metal machine frame surface, where possible.

This simulates a shield, which will help minimize the effects of EMI/RFI radiation.• Do not run the wires near sharp metal corners. Consider running the wire through a

grommet when rounding corners.• Avoid running wires near moving or vibrating components.• An experienced person should carry out the installation of CB-radios and mobile

phones. Special attention should be paid to the routing of the wires and the position of the antenna. In any case, the wiring should be separated from other wiring. TME controllers from Sauer-Danfoss are insensitive to electromagnetic fi elds up to a level of 100V/m. Should there be a problem, the radiation interference is probably too high. Possible reasons could be the antenna position, refl ection or interference through the wiring.

• The electronics should be mounted in a way that the wiring is facing down.• Unused cavities in connectors must be fi lled with cavity plugs.

Recommended tools for assembling wires to pins are available and help insure that the connections are mounted in the correct way.See below

• Crimp Tool for Power Timer - AMP/16-pin: Id. No. 509 575• Die Set for 509 575: Id. No. 509 576

If you push in the pin into a wrong connector position you can remove the mechanical locked pin with the following tool:

• Contact Extraction Tool for Power timer: Id. No. 517 024

The tools below are also available to assemble wire-pins for the proportional valve con-nectors: • Crimp Tool for Micro Timer - AMP/2-pin: Id. No. 515 895• Die Set for 515 895: Id. No. 515 896• Contact Extraction Tool for Micro Timer: Id. No. 517 023

Start-Up Procedure

GENERAL

GEARBOX

HYDROSTATICS

Before start-up fi ll with EP-Gear lubricant SAE 90, API-Classifi cation GL 5, FZG power stage > 12 acc. DIN 51 354 (see table gear box „Specifi c Data“).Fill the lubricant up to the mark of the oil dipstick and check oil level regularly.

Before start-up fi ll the system in following way with oil acc. to Sauer-Danfoss literature520L0463.

• After installing the transmission and corresponding pipeline connections, remove the plug from the gage pressure port M3 of the variable displacement pump. Fit a gage with a measuring range up to 60 bar [1000 psi] at this port.

• Disconnect the charge pump inlet line from the charge pump inlet connection pipe.• Fill the pump and motor housing by pouring fi ltered oil into the upper case drain

port.• Fill the reservoir with recommended hydraulic fl uid. As soon as oil emerges from the

end of the disconnected charge pump inlet line tighten the pipe connection and continue to fi ll the reservoir.

• Remove both connectors on the proportional valves of the variable displacement pump.

• Allow the engine to turn app. 15 seconds by using the starter.• Then start the engine and allow the pump to turn at idle speed [app. 650-700 min-1 (rpm)].After initial fl uctuations in pressure the charge pressure should be settle downto 19±1 bar [275±14.5 psi].• Check the oil level in the sight glass. Refi ll, if necessary.• Raise the speed to normal operating speed. The gage should now indicate the pres-

sure setting of the charge pressure relief valve.• If charge pressure is not maintained at the proper setting, stop the engine and fi nd

the fault in accordance with the troubleshooting guide.• Stop the engine and fi t the connectors to the proportional valves of the variable dis-

placement pump. • Restart the engine, check the pump should remain in the neutral position (no drum

rotation). With engine at normal operating speed, app. 1500-1600 min-1 (rpm), select the lowest

position of on the TME rotary switch for the drum rotation direction for charge and discharge.

• If the drum turns in the wrong direction, stop the engine. Remove the connectors for the proportional valves on the variable displacement pump. Switch and connect again.

• Restart the engine and check the rotation direction of the drum once more. If okay, turn the drum slowly in both directions for 5 minutes.

• Check all joints and connections for leaks.• Check CSD-function with the pre-selected “Transport Mode“ on the controller while

varying the engine output speed. Under these circumstances, the drum speed should

be constant at 2 min-1 (rpm).• Check the functions for TME controllers at a engine speed approximately

1500-1600 min-1 (rpm) (direction/speed/stop-start on the remote/switch over from the cabin to remote).

• Warm up the system and check again for leaks.• Stop the engine. Remove the gage from the connection port M3. Replace the plug

and tighten with the proper torque.• Check oil level in the sight glass of the reservoir and fi ll to the proper level, if neces-

sary.

Maintenance

GEARBOX TMG

HYDROSTATICTMP AND TMM

First oil change should be after 100 hours, then after every 1000 hours, but at least once a year. Use only recommended gear lubricants; see Sauer-Danfoss literature 520L463 (Hydrau-lic Fluids and Lubricants, Technical Information).

The level of the oil should be checked daily. In case of loss of oil, the leak should be recti-fi ed and refi ll oil, if necessary.

Periodically clean the gear housing and inspect for loosened screws and bolts.

Gearboxes Series TMG 51.2, 61.2 and 71.2 are designed and manufactured for safe opera-tion and the highest level of technology. However, there are certain dangers inherent if they are improperly operated or if they are used for other purposes than they were intended, for example, by unskilled personnel. This may result in• dangers for life and limb• dangers for machines and other company assests• adverse effects on the effi ciency of the operation Any person involved in the start up, maintenance, and inspection of the gearbox TMG or the hydrostatic transmission, must read and understand the appropriate Service Manual.

Sauer-Danfoss offers training programs.

The fi lter must be also changed if the inlet vacuum pressure is less than 0.7 bar absolute [-9 in. Hg] with oil operating temperatures higher than 50 °C [122 °F].A continuous inlet pressure of less than 0.5 bar absolute [-15 in. Hg] is not permissible.The fi lter may require changing, or the oil temperature is to low, or the viscosity of the oil is too high (too thick oil).

The oil should be changed after maximum 100 hours of operation. The second oil change should be after 500 hours. Thereafter, every 1000 hours or at least once a year.It is not permissible to mix oils of different brands.Change oil fi lters when changing the oil.

Carry out a leak test on transmission (inlet line, fi lter, pipe- and hose lines, valves, pump and motor) giving due consideration to service life, environmental protection and reduc-tion of oil consumption. Check the reservoir for proper oil level via the sight glass and refi ll, if necessary.

SAFETY

When cleaning with a high pressure water jet do not

direct the jet onto the fl ange shaft seal, because

this may lift the seal lip and force contamination

underneath the seal lip, resulting in premature

wear and damage of the lip seal.

Tighten up any leaking joints and other connec-tions while system is not

under pressure.Replace defective seals.

37


DKMH.PS.800.B1.02 • 520L0482 • Rev A • 05/2004

Maintenance

Check hydraulic hoses periodical and change when there is any damage or ageing (see manufacturers instruction). Replacement hoses should be in accordance to specifi ca-tions. When reassembling do not exchange connection ports of pipes and hoses.When exchanging system pressure ports, the direction of drum rotation will be changed.

Make certain that the oil fi lter for ventilation of the oil reservoir is regularly cleaned, since the input pressure may be affected if it is dirty. The cooler surface should be kept free from contamination.Cotton rags or lint cleaning cloths must not be used for cleaning. Use lint-free materials only.When changing the oil, be sure the area around the cap is free from foreign objects. The level of the oil should be checked daily using the gage glass. In case of loss oil, the leak must be rectifi ed and refi lled, if necessary.

HYDROSTATICTMP AND TMM(continued)

Without this safety pre-cautions there could be danger for body and life

e. g. danger for machines and property.

Use only recommended fl uids acc. Sauer-Danfoss

literature 520L0463.It is not permissible to mix

oil of different brands.
