The drive shaft transmits the power of the car to the tires, but during the use of the car, the drive shaft will hear abnormal sounds. What causes the abnormal sound of the driving shaft?

1. Due to long-term high-speed operation, the transmission shaft is bent, and abnormal sound is emitted when transmitting power. The intermediate support bearing of the drive shaft wears away too much, the axial and radial clearance increases, and the sound is produced during rotation.

2. If grease is not added in time, the oil seal of the cross shaft is damaged and oil leaks. This allows the cross shaft needle roller bearings to operate under the condition of chronic lack of lubricating oil. To form loose and unusual sounds.

3, the transmission shaft is inaccurate parts size and wear and deformation during use will lead to the transmission shaft along the length of the direction of uneven distribution, resulting in unbalanced transmission. The unbalanced shaft will generate additional bending moments during operation.

4, if the intermediate shaft rubber aging or support fixed screws loose, the transmission shaft in the running process will produce abnormal noise, if not strengthened in time, the transmission shaft will fall off.
