The driving shaft of the car is a rotating body with high speed and little support, which is very important for the dynamic balance of the car. Therefore, the driving shaft of the car should be tested before the car leaves the factory, and it should be adjusted on the dynamic balance machine. For the front engine rear wheel drive vehicle, the car's transmission shaft is a very important component, the transmission shaft is composed of axle tube, telescopic sleeve and universal joint, can automatically adjust the distance between the transmission and the drive axle. The universal joint is a key part of the automobile transmission shaft, which is installed between the transmission output shaft and the drive axle main reducer input shaft. The relative positions of the two axes are guaranteed to transfer power within the expected range.

When the car's driving shaft suspension is broken, the car may appear serious abnormal sound, leading to the car pedal can not drive the phenomenon of moving. The drive shaft of the car is broken is generally the drive shaft deformation, or girder deformation caused by the need for timely maintenance.
