It consists of parts: transmission shaft, star sleeve, cage, steel ball, bell shell, grease and etc.

    CV joint is also known as the "constant velocity universal joint", which is an important part of the car's transmission system. The function is to transfer the power of the engine from the transmission to the driving wheel, to make car drive at high speed. Generally, it divides into inner CV joint and outer CV joint. Inner CV joint effectively connects gearbox and differential mechanism, outer CV joint is mainly connected to the wheel parts. Whether its power output or vehicles in turn, outer CV joint is at work.

    In order to ensure sufficient lubrication of CV joint, high temperature resistant lubricating greases that the main components is molybdenum disulfide is used.
