Drive shaft encyclopedia

The drive shaft (Driveshaft) is a round object fitting which can be moved or rotated by connecting or assembling various fittings. It is usually made of light alloy steel pipe with good torsion resistance. For a car with a front-engine rear-wheel drive, the transmission is transferred to the shaft of the main reducer.

Structure composition

The drive shaft is composed of a shaft tube, a telescopic sleeve and a universal joint. The various parts link up with each other, cooperate, and play a great role together. Telescopic sleeve-automatically adjusts the distance between the transmission and the drive axle.

Universal joint is to ensure the change of the angle between the output shaft of transmission and the transmission shaft of drive axle, and to realize the equal angular speed transmission of two axes. The drive shaft is a rotating body with high speed and little support, so its dynamic balance is very important. General transmission shaft before the factory to carry out dynamic balance test, and must be adjusted through the balancing machine.

classify

Automobile drive shaft according to different classification, can be divided into open and closed. The open drive shaft is widely used because of its easy installation, repair and maintenance.

According to whether the universal joint has obvious elasticity in the torsional direction, it can be divided into rigid universal joint drive shaft and flexible universal joint drive shaft. In view of the characteristics of the universal joint, the cross shaft rigid universal joint drive shaft is most widely used in the automobile transmission system.

In general, the function of automobile drive shaft is to transfer power between two axles with different axes and even between two axles with changing relative position in the process of operation.
