Do you understand the dynamic balance of the transmission shaft?

Do you know the drive shaft? The transmission shaft is a rotating body with high speed and few bearings, so its dynamic balance is very important. Generally, the transmission shaft must be tested on a dynamic balancing machine before leaving the factory, and adjusted on the balancing machine. For a car with a front-engine rear-wheel drive, it is the shaft that transmits the rotation of the transmission to the final drive. It can be several sections, and the sections can be connected by universal joints.

The transmission shaft is composed of a shaft tube, a telescopic sleeve and a universal joint. The telescopic sleeve can automatically adjust the change of the distance between the transmission and the drive axle. The universal joint is to ensure the change of the angle between the output shaft of the transmission and the input shaft of the drive axle, and to realize the transmission of the two shafts at equal angular speeds.

If the drive shaft is broken, more people may not have noticed the harm to the car drive shaft. but! It is important to know that the transmission shaft is an indispensable part of the transmission of power in the automobile transmission system! When the transmission shaft is damaged, the car will make a creaking noise; and the rear of the car may vibrate violently when the car is driving at a relatively high speed; in severe cases, the car cannot be started and cannot move even when the accelerator is stepped on. If it is really badly damaged, it is necessary to replace the drive shaft in the auto repair shop for a few thousand dollars.
