Drive shaft is a rotating body with high speed and little support, so its dynamic balance is very important. The general drive shaft before leaving the factory must be into the action balance test, and the balance machine has been adjusted.

For front-engine and rear-wheel drive cars, it is the shaft that transfers the transmission's rotation to the main reducer. It can be several sections, which can be connected by universal joints.

The drive shaft is composed of shaft tube, telescopic sleeve and universal joint.

The telescopic sleeve can automatically adjust the change of distance between the transmission and the drive axle.

Universal joint is to ensure the change of the Angle between the two axes of the transmission output shaft and the input shaft of the drive axle, and realize the equiangular speed transmission of the two shafts.
