A car is a moving object. In the rear drive car, the engine, clutch and transmission are mounted on the frame as a whole, while the drive axle is connected to the frame by means of an elastic suspension. There is a distance between the two axles, which need to be connected. The car running road surface bouncing, load change or two assembly position difference, will make the transmission output shaft and the drive axle main reducer between the transmission input shaft angle and distance change, so use a device to change the strain "to solve the problem, so there is the joint of this thing.
At present, the rear drive automobile is the most widely used type of universal universal joint, consisting of such parts as universal joint, fork and cross axle. The cross shaft assembly connected in universal joint fork shaft, cross shaft is arranged on the needle bearing, when the access shaft universal joint fork, a relative rotation can be between the cross shaft and universal joint fork, the change will produce a multi angle.
A single universal joint can not make the output shaft equal to the instantaneous angular speed of the shaft into the shaft. It is easy to cause vibration, aggravate the damage of the parts and make a lot of noise. Therefore, a universal joint transmission form drive vehicles are double gimbal, the drive shaft is at each end of a universal joint, is to make equal angles of both ends of the transmission shaft, ensure the output shaft and the shaft shaft into the instantaneous angular velocity is always equal.
