Definition of universal joint bearing

所谓万向节轴承，指的是利用球型连接实现不同轴的动力传送的机械结构，是汽车上轴承一个很重要的部件。而前置发动机前轮驱动的车辆省略了传动轴，万向节安装在既负责驱动又负责转向的前桥半轴与车轮之间。在前置发动机后轮驱动的车辆上，万向节传动装置安装在变速器输出轴与驱动桥主减速器输入轴之间。万向节与传动轴组合，称为万向节传动装置。

The so-called universal joint bearing refers to the mechanical structure that realizes the power transmission of different axes by ball connection, and it is a very important part of automobile upper bearing. The front wheel drive motor vehicle omits the transmission shaft, and the universal joint is installed between the front axle and the axle of the front axle which is responsible for driving and steering. On the rear wheel drive vehicle of the front engine, the universal joint transmission device is installed between the transmission output shaft and the input shaft of the drive axle main reducer. The combination of universal joint and transmission shaft is called universal joint transmission device.

为方便理解，以最常用的十字万向节为例，通过一段精彩的动画展示，清楚说明万向节的工作原理  ↓↓

To facilitatewww.yanglaoyuany.com.cnwww.yanglaoyuana.cn www.jianchajingmujuu.cn www.gangmoju.net.cn www.dianlancao.net.cn www.uxingcaomoju.com.cn understanding, take the most commonly used cross universal joint as an example, through a wonderful animation display, clearly explain the working principle of the universal joint.

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 structure and function of the universal joint are similar to the joints on the human limbs. It allows the angle between the connected parts to change within a certain range.

万向节有两大分类，根据在扭转方向上是否有明显弹性分为刚性万向节和挠万向节

There are two classifications of universal joints. According to whether there is obvious elasticity in the direction of torsion, they can be divided into rigid universal joints and flexible universal joints.

The classification of the bearing of the universal joint

准等速万向节和等速万向推力球轴承节

Quasi constant speed universal joint and constant speed universal thrust ball bearing section.

常见的准等速万向节有双联式和三销轴式两种，它们的工作原理与双十字轴式万向节实现等速传动的原理是一样的。双联式万向节实际上是一套将传动轴长度减缩至最小的双十轴承字轴式万向节等速传动装置，双联叉相当于传动轴及两端处在同一平面上的万向节叉。在当输出轴与输型号查询入轴的交角较小时，能使两轴角速度接近相等，处在圆弧上的两轴轴线交点离上述中垂线很近，使得α调心滚子轴承1与α2的差很小，所以称双联式万向节为准等速万向节。

The common quasi constant speed universal joints have double and three pin axis two, and their working principle is the same as the principle of the double cross shaft universal joint for equal speed transmission. The double joint universal joint is actually a set of double - bearing type - shaft type universal joint drive unit, which reduces the length of the drive shaft to the minimum. The double fork is equivalent to the drive shaft and the universal joint at both ends in the same plane. When the intersection angle between the output axis and the input model is smaller, the angular velocity of the two axis angle is equal to the same, and the intersection point of the two axis axis on the arc is very close to the above vertical line, making the difference between the 1 and the alpha 2 of the alpha adjustable roller bearing very small, so the double joint universal joint is called the quasi constant universal joint.
