Automotive axles are an important part of automotive transmission systems

With the rapid development of China's automobile industry, the demand for automobile axles is increasing. How to improve the output and quality of automobile axles, reduce the production cost of axles, realize economic production of semi-axles, and meet the needs of the market has become Important issues that need to be addressed urgently. Therefore, it is of great practical significance to explore the method and technology of automobile semi-axis precision forming. The car axle is an important force transmission component of the car. It not only transmits the torque from the car engine, but also the vertical force acting on the wheel, the lateral force and the longitudinal force formed by the traction and braking forces. Therefore, the car axle is an important part of the automotive transmission system.
