Constant velocity universal joint

     A constant velocity universal joint is a device that connects two shafts with varying angles or positions between them, and  transmits power at the same angular velocity. It can overcome the problem of non-uniformity in ordinary cross axis universal joints. The widely used constant velocity universal joints mainly include ball fork universal joints and ball cage universal joints.

     The function of a constant velocity universal joint is to connect two shafts with varying angles or positions between them, and to transmit power at the same angular velocity. It can overcome the problem of non-uniformity in ordinary cross axis universal joints and is particularly suitable for the use of steering drive axles.

     At present, the widely used constant velocity universal joints mainly include ball fork universal joints and ball cage universal joints. According to the different shapes of steel ball raceways, ball fork universal joints can be divided into two types: arc raceway type and straight groove raceway type; According to whether the axial direction of the universal joint can move, cage type universal joints are divided into fixed cage type universal joints (RF joints) and telescopic cage type universal joints (VL joints).
