Generally speaking, the drive axle

Generally speaking, the drive axle housing is mainly divided into non-disconnected axle housing and disconnected axle housing. The drive axle housing mainly protects the main reducer, differential, half shaft and other components from interference from external factors. At the same time, the axle housing is also the main part of the driving system, which can also bear the weight of the vehicle body and is an indispensable part of the drive axle [19].The structural forms of axle housing can be roughly divided into two types: integral type and sectional type. Because this design is a heavy-duty truck, the main problems to be considered are load and stiffness requirements. In the whole design process of axle housing, low cost, simple structure and convenient manufacture should be required, and how to disassemble, adjust, repair and maintain the main reducer should be considered. The main factors to be considered when choosing the structural form of axle housing are: automobile type, service requirements, manufacturing conditions, material supply, etc.In this design, the integral cast axle housing is finally selected. Because it has many advantages in many aspects: it has strong plasticity, can be made into complex and ideal shape, can change the wall thickness at will, will be idealized in stress distribution, and has high strength and stiffness, and reliable and stable working performance
