Off-road vehicle transmission and transfer between the front drive steering axle and half shaft, all need this joint to do "joint". The gimbal structure and function a bit like the joints on human limbs, it allows the Angle between the connected parts to change. However, it is different from the movement form of the limb joint, which only allows the included Angle to change within a certain range.

Universal joint has cross shaft type rigid universal joint, quasi-constant velocity universal joint (double shaft type and three pin shaft type), constant velocity universal joint (ball fork type and ball cage type), disturbing universal joint. One of the most widely used rear drive vehicles is the cross shaft universal joint.

A single universal joint cannot make the instantaneous angular velocity of the output shaft equal to that of the shaft into the shaft, which is easy to cause vibration, aggravate the damage of the parts, and generate a lot of noise. Therefore, after the drive car's universal joint drive form all USES the double universal joint, is the drive shaft both ends have a universal joint, its function is to make the drive shaft at both ends of the Angle is equal, ensure that the output shaft and the shaft into the shaft instantaneous angular velocity is always equal.

In order to meet the power transfer, steering and car running when the up and down jump caused by the Angle change, the front drive car drive axle, half shaft and wheel shaft are also commonly connected by universal joint. Due to the limitation of axial dimension and the large deflection Angle required, ordinary universal joints are not up to the standard. In the general front drive car, each half shaft with two constant speed universal joint, near the variable drive axle universal joint is half shaft inside universal joint, near the axle is half shaft outside universal joint. In all kinds of constant speed universal joint, common is the ball cage type universal joint, it USES six steel ball transmission force, driving shaft and driven shaft in any case of the intersection of the ball is located in the intersection of the two parks, that is, on the bisector of the Angle of the two axes, so as to ensure that the main and driven shaft equiangular speed transmission.
