OEM China Chery T21 - High Quality universal drive shaft types of drive shaft – Qingzhi

The drive shaft (DriveShaft) connects or assembles various accessories, and the accessories of round objects that can be moved or rotated are generally made of light alloy steel pipes with good torsion resistance. For a front-engine rear-wheel drive car, it is the shaft that transmits the rotation of the transmission to the final reducer. It can be connected by universal joints in several sections. 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.

The transmission shaft is a rotating body with high speed and less support, so its dynamic balance is very important. Generally, the transmission shaft shall be subject to action balance test before leaving the factory and adjusted on the balancing machine. For front engine rear wheel drive vehicles, the rotation of the transmission is transmitted to the shaft of the main reducer. It can be several joints, and the joints can be connected by universal joints.
The transmission shaft is an important component in the automobile transmission system to transmit power. Its function is to transmit the power of the engine to the wheels together with the gearbox and drive axle to generate driving force for the automobile.
The transmission shaft is composed of shaft tube, telescopic sleeve and universal joint. The telescopic sleeve can automatically adjust the change of the distance between the transmission and the drive axle. The universal joint ensures the change of the included 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.
On the vehicle with front rear wheel drive (or all wheel drive) of the engine, due to the deformation of the suspension during the movement of the vehicle, there is often relative movement between the input shaft of the drive shaft main reducer and the output shaft of the transmission (or transfer case). In addition, in order to effectively avoid some mechanisms or devices (unable to realize linear transmission), a device must be provided to realize the normal transmission of power, So universal joint drive appeared. The universal joint drive must have the following characteristics: A. ensure that the relative position of the connected two shafts can reliably transmit power when it changes within the expected range; b. Ensure that the connected two shafts can run evenly. The additional load, vibration and noise caused by the included angle of the universal joint shall be within the allowable range; c. High transmission efficiency, long service life, simple structure, convenient manufacture and easy maintenance.
