About Drive shaft

The drive shaft is an important part of the transmission of power in the automobile driveline. Its function is to transmit the power of the engine to the wheels together with the gearbox and drive axle, so that the automobile generates driving force.

The drive shaft is composed of a shaft tube, a telescopic sleeve and a universal joint. The telescopic sleeve can automatically adjust the distance between the transmission and the drive axle. The universal joint guarantees the change of the angle between the output shaft of the transmission and the input shaft of the drive axle, and realizes the constant angular speed transmission of the two shafts. It is a rotating body with high speed and less support, so its dynamic balance is very important. Generally, the drive shaft must undergo a dynamic balance test before leaving the factory and be adjusted on a balance machine. For a front-engine rear-wheel drive car, the rotation of the transmission is transmitted to the shaft of the final reducer. It can be several sections, and the sections can be connected by universal joints.
