Body classification
Non-load-bearing bodyA car with a non-load-bearing bodyhas a rigid frame, which is also called chassis side rail frame. In the non-load-bearing car body, the engine, a part of the transmission system, the car body and other assembly parts are fixed on the car frame with suspension devices, and the car frame is connected with wheels through front and rear suspension devices. Non-load-bearing car body is large in size, heavy in weight and high in height. It is generally used in trucks, buses and off-road vehicles, and also used in some advanced cars because of its good stability and safety.
Second, the load-bearing body does not have a rigid frame, but only strengthens the front, side wall, rear and floor. Assemble the engine, front and rear suspensions, part of the transmission system and other assembly parts on the car body at the position required by the design, and transfer the car body load to the wheels through the suspension device. In addition to the inherent load-bearing function, the load-bearing car body directly bears various load forces. The safety and stability of the load-bearing car body have been greatly improved. It has the advantages of light weight, low height and easy assembly. Most cars use this body structure.
