It is generally composed of two longitudinal beams and several cross beams, and is supported on the wheels through the suspension device, the front axle and the rear axle. The frame must have sufficient strength and rigidity to withstand the load of the car and the impact from the wheels. The function of the frame is to support and connect the various assemblies of the car, keep the assemblies in a relatively correct position, and withstand various loads inside and outside the car.
