等速万向节是把两个轴线不重合的轴连接起来，并使两轴以相同的角速度传递运动的机构。是轿车传动系统中的重要部件，其作用是将发动机的动力从变速器（差速器）传递到汽车的驱动轮，满足轿车传动轴外端转角的要求；将发动机的动力平稳、可靠的传递给车轮；补偿轿车内端悬架的跳动。驱动轿车高速行驶。 

The constant velocity universal joint is a mechanism that connects two axes which do not coincide, and transfers two axes at the same angular speed. It is an important part of the car transmission system. Its function is to transfer the engine power from the transmission (differential) to the driving wheel of the car, to meet the requirement of the outer end of the car's drive shaft, to transfer the engine's power to the wheel smoothly and reliably, and to compensate the runout of the inner end of the car. Drive a car at a high speed.  

用于轿车的等速万向节类型很多，其中应用最多的是球笼式等速万向节和三槽式等速万向节、斜滚道式等速万向节，它主要内球笼、外球笼、半轴组成。由于等速万向节传递繁重的驱动力矩，随受负荷重，传动精度高，需求量很大，又是安全件，因此其主要零件均采用精锻件加工而成

There are many types of constant speed universal joints used in cars, of which the most used are the ball cage type constant speed universal joint and the three slot constant speed universal joint, the inclined roll channel type constant speed universal joint, which mainly consists of the ball cage, the outer ball cage and the half shaft. Because the heavy driving torque of the constant speed universal joint is heavy, the transmission precision is high, the demand is great, and it is the safety part, so the main parts are made of fine forgings.
