Background

The automobile axle (also called as axle) is connected with the frame (or the bearing type automobile body) through the suspension, and wheels are arranged at the two ends of the automobile axle. The axle is used for bearing the load of the automobile and maintaining the normal running of the automobile on the road. According to different driving modes, the axle is also divided into a steering axle, a driving axle, a steering driving axle and a supporting axle. Wherein the steering axle and the support axle belong to the driven axle. Most automobiles employ front rear drive (FR), so the front axle acts as a steering axle and the rear axle acts as a drive axle; whereas a front-drive (FF) car has the front axle as the steering drive axle and the rear axle as the support axle.

The automobile axle needs to be maintained sometimes, and can be disassembled and assembled only by placing the automobile axle well, and if the automobile axle is directly placed on the ground, an operator can only bend down to operate the automobile axle, which is inconvenient and laborious; in addition, the direct placement of the vehicle axle on the ground can cause the vehicle axle to easily shake and cause a certain part of the vehicle axle to be scratched due to impact.
