Car Frame (Chassis)

The basic structure of the vehicle is the frame and it provides a good anchor point for the suspension system. There are two types of frames; integral frames, or ‘unibody’, and conventional frames. The rectangular, usually steel frame, supported on springs and attached to the axles, that holds the body and motor of an automotive vehicle. A conventional frame is basically a ‘one-piece’ frame; or two ‘one-piece’ frames fastened together. These frames are extremely rigid to keep all the parts of the car in perfect alignment, which are attached to it. It is constructed of heavy steel and welded or cold riveted together. Cold riveting keeps the rivets from shrinking after they cool off.
