万向节是指利用球型等装置来实现不同方向的轴动力输出,位于传动轴的末端,起到连接传动轴和驱动桥、半轴等机件。万向节的结构和作用有点像人体四肢上的关节,它允许被连接的零件之间的夹角在一定范围内变化。
The universal joint refers to the use of the ball type device to realize the axis power output in different directions, at the end of the transmission shaft, and the connecting drive shaft, the driving axle and the half shaft. The structure and function of the universal joint are somewhat like the joints on the limbs of the human body, which allow the angle between the parts to be connected to change within a certain range.
前置后驱的汽车,必须将变速器的动力通过传动轴与驱动桥进行连接,那万向节能起到什么作用呢?主要是为了满足动力传递、适应转向和汽车运行时所产生的上下跳动所造成的角度变化。
The front drive rear drive vehicle must connect the transmission power through the drive shaft and the drive axle. What role does the universal energy saving play? The main purpose is to meet the angle changes caused by power transmission, adaptation to steering and running up and down.
按万向节在扭转方向上是否有明显的弹性可分为刚性万向节和挠性万向节。刚性万向节又可分为不等速万向节(常用的为十字轴式)、准等速万向节(如双联式万向节)和等速万向节(如球笼式万向节)三种。
According to whether the cardan joint has obvious elasticity in torsion direction, it can be divided into rigid universal joint and flexible universal joint. The rigid universal joint can be divided into three kinds: unequal speed universal joint (commonly used for cross shaft), quasi constant speed universal joint (such as double joint universal joint) and constant speed universal joint (such as ball cage universal joint).
