The structure and function of the universal joint are somewhat like the joints on the limbs of the human body, which allow the angles between the parts to be connected to vary within a certain range. In order to satisfy the angle change caused by the fluctuation of the power transmission, the steering and the fluctuation of the running of the automobile, the drive axle of the front drive automobile is connected with a cardan joint between the half shaft and the wheel shaft. But due to the axial size, angle requirements and relatively large, single gimbal can make the output shaft and the shaft shaft into the instantaneous angular velocity equal to cause vibration, damage aggravated components, and have a lot of noise, so it is widely used in every kind of the constant velocity universal joint. On the front drive automobile, each half shaft is provided with two constant velocity universal joints, and the universal joint adjacent to the variable speed drive axle is a half shaft inner universal joint, and the axle shaft is a cardan joint of the half shaft. 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 installed position, will make the transmission output shaft and the drive axle main reducer between the transmission input shaft angle and distance change, Cardan drive cars in the form so the double universal joint, drive shaft at each end is there is a universal joint, its role is to make equal angles of both ends of the transmission shaft, so as to ensure the output shaft and the input shaft of the instantaneous angular velocity is always equal.
