Is urv a load-bearing body?
Introduction of load-bearing body
The load-bearing car body has no frame, so the car body serves as the installation foundation of the engine and chassis assembly, and at the same time, the car body also serves as the frame to bear all the loads. Structure for mounting chassis components (engine, suspension, etc.). ) directly placed on the car body is mainly composed of thin plates. In order to reduce the stress on the chassis parts and ensure the rigidity of the car body, some vehicles will be equipped with sub-frames.
One end of the chassis is mounted on the subframe, which is also mounted on the vehicle body. In the foundation load-bearing type, the part below the waist line of the side wall of the car body (including the bottom structure of the side wall skeleton from the bottom beam to the floor) is designed as the main load-bearing part of the car body, and the top cover is considered as the non-load-bearing part, which can reduce the cross section of the window column.
The longitudinal and transverse members at the bottom of this structure can generally be made of thin-walled steel and thin plates, which are generally used for long-distance or tourist buses.
