[0002] The main function of a truck frame is to support and connect the various assemblies of the vehicle, keep the assemblies in a relatively correct position, and bear various loads inside and outside the vehicle. The general structural form of a truck frame is a frame structure that spans the front and rear axles of the vehicle, commonly known as a beam. The traditional truck frame is mainly composed of two longitudinal beams and several cross beams. The longitudinal beams run from the front to the rear and are supported on the wheels through the suspension device, front axle, and rear axle.
[0003] The traditional frame occupies the main layout space due to its own width and height. In actual vehicle layout, the side hanging method is often used to hang various parts on both sides of the longitudinal beam, and the utilization rate of the middle space is low. There is a drive shaft in the middle of the fuel vehicle, and this part of the space is relatively utilized. However, the vehicle parts of new energy trucks have subversive changes compared to traditional fuel vehicles. The traditional frame structure cannot arrange large-volume parts, such as battery packs; at the same time, the middle space cannot be fully utilized. This means that the whole vehicle must meet the layout requirements by increasing the wheelbase and using the space behind the cab, which brings a series of problems such as increased vehicle length, higher center of gravity, increased deadweight, increased turning radius, and compressed cargo box length.
