The vehicle running load and impact load are mainly borne by the frame, and the deformation of the car body is relatively small. But this kind of non load bearing body is bulky, of high quality, high center of gravity and poor stability at high speed. The semi load type body is characterized in that the body is rigidly connected with the frame by screws, riveting or welding. In this case, in addition to the above-mentioned load, the car body is also helpful to reinforce the frame and share part of the load of the frame.
