On rear wheel drive vehicles with front engine, the universal joint drive shaft is installed between the output shaft of the transmission and the input shaft of the main reducer of the drive axle; The front engine front wheel drive vehicles omit the transmission shaft. Xuchang Shenbang machinery tells you that the universal joint is installed between the front axle half shaft and the wheel, which is responsible for driving and steering.

According to the different loads of the shaft, the transmission shaft can be divided into: the rotating shaft, the spindle and the transmission shaft.

Transmission shaft parts are one of the important parts of mechanical transmission on diesel locomotive. The function of the transmission shaft of Dongfeng 4 locomotive is to transmit the output power of the diesel engine to the hydrostatic gearbox, drive the two hydrostatic pumps to work and pump out the high-pressure hydrostatic oil. At the same time, according to the requirements of oil and water temperature, drive and adjust the hydrostatic motor to work and cool the high and low-temperature cooling water.

Transmission shaft accessories are an important part of transmission equipment. Although its role is not as big as that of main accessories, it is also essential in work.

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.
