What is the cause of the rupture of the cage of the half shaft ball cage

The rupture of the half-shaft cage cage is most likely caused by the slight deformation of the half-shaft. The half-shaft ruptures due to shaking at high speed. If you want to completely solve it, you can only replace the entire half-shaft assembly.

The ball cage, also called "constant velocity universal joint", is an important component in the car transmission system. Its function is to transfer the power of the engine from the transmission to the two front wheels to drive the car to drive at high speed. There are many types of constant velocity universal joints used in cars. Among them, the most widely used are ball cage type constant velocity universal joints and tripod type constant velocity universal joints. They mainly include sliding sleeves, three-way shafts, drive shafts, and star shapes. It is composed of main parts of sleeve, cage and bell shell.

Constant velocity universal joint is a device that connects two shafts that have an angle between the shafts or changes in mutual position, and enables the two shafts to transmit power at the same angular velocity. It can overcome the inequality of ordinary cross shaft universal joints. Speed ​​issue. Currently, the widely used constant velocity universal joints mainly include ball and fork type universal joints and ball cage type universal joints.

In the steering drive axle, the front wheel is both the driving wheel and the steering wheel. The deflection angle during steering is large, and the maximum can reach more than 40°. At this time, the conventional universal joint with a small deflection angle cannot be used. Ordinary universal joints will have great fluctuations in speed and torque when the deflection angle is large. It is difficult for the power of the car engine to be transmitted to the wheels smoothly and reliably, and it will also cause vibration, shock and noise of the car. Therefore, a constant velocity universal joint with large deflection angle, stable power transmission, and uniform angular velocity must be used to meet the requirements.
