TYPES OF CHASSIS FRAMES:
There are three types of frames
1. Conventional frame
2. Integral frame
3. Semi-integral frame
1. Conventional frame:
It has two long side members and 5 to 6 cross members joined together with the help of rivets and bolts. The frame sections are used generally.
a. Channel Section – Good resistance to bending
b. Tabular Section – Good resistance to Torsion
c. Box Section – Good resistance to both bending and Torsion
2. Integral Frame:
This frame is used now a days in most of the cars. 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. Due to elimination of long frame it is cheaper and due to less weight most economical also. Only disadvantage is repairing is difficult.
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. This type of frame is
used in some of the European and American cars.
