- 4. Definition; • 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. Dig of Automobile chassis Frame Front cross member X-Member Side Member
- 5. 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 Chassis Frame of Jeep
- 6. Types of Automobile chassis frames There 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
- 7. 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

- 9. Material Details Material 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)
- 10. Design Details Load 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. Acting Loads Frame
