IntroductionDefinition;• Frame is a under carriage or
structure that supports the engine and cab(body)of the automobile.
• It is made up of long two members called side members riveted together with the help of number of cross members.

Functions of chassis Frame
• To carry load of the passengers or goods carried in the body.
• To support the load of the body, engine, gear box etc.,
• To withstand the forces caused due to the sudden braking or acceleration
• To withstand the stresses caused due to the bad road condition.
• To withstand centrifugal force while cornering

Types of Automobile chassis framesThere are three types of frames:1.Conventional frame: It has two long side members and 5 to
6 cross members joined together with the help of rivets and bolts.
Frame Sections used in this type of frame;
a. Channel Section - Good resistance to bending
b. Tabular Section - Good resistance to Torsion
c. Box Section - Good resistance to both bending and Torsion
Uses: In Buses ,Trucks , Vans etc Cont……….
Conventional Frame
2.Integral type of frame• There is no frame and all the
assembly units are attached to the body
• All the functions of the frame carried out by the body itself.
Uses; In all Modern Cars,
3.Semi-Integral Frame• In some vehicles half frame is
fixed in the front end on which engine gear box and front suspension is mounted.
• It has the advantage when the vehicle is met with accident the front frame can be taken easily to replace the damaged chassis frame.
Uses; Tractors , Fiat Cars

Manufacturing of chassis frame
Detail Procedure Material Details Design Details Manufacturing
process Inspection
Material DetailsMaterial selection of frame depends on: Type of Vehicle(Heavy , Light) Chassis Design (Engine Components location) Manufacturing Company
Recommended Materials: Cast Iron (for Heavy Vehicles) HSS ,Steel (Medium , Foreign Vehicles) Aluminum Alloys (Light Vehicles)
Design DetailsLoad Analysis:Various loads acting on the frame are;
Short duration Load - While crossing a broken patch.
Momentary duration Load - While taking a curve.
Impact Loads - Due to the collision of the vehicle.
Inertia Load - While applying brakes.
Static Loads - Loads due to chassis parts.
Over Loads - Beyond Design capacity.

Manufacturing Process
o Drawing Projection o Cutting o Bendingo Welding o Finishing & Inspection
1. Drawing Projection
• Drawing is acquired from design department• Marking is done according to design • Allowances will be provided• Further process will be carried out
Equipments Used Design SoftwareOther tools used in Design Department
2.Cutting
• It is process after drawing projection• Cutting process is done according to marking • Side members of frame are got by cutting the long
beam sections from a raw metal
Equipments Used General cutting MachinesSpecialized cutting MachinesCNC Cutting MachinesLAZER Cutting Machines
3.Bending
• Bending process is carried out after cutting process• Bending is done according to the angle specified.• In frame, bending is done while fitment of cross
members.
