Universal Drive Shaft | Solutions to the Common Failure

Views:15     Author:Cardan Shaft Manufacturer     Publish Time: 2020-10-15      Origin:Sitong Cardan Shaft Co.,Ltd

The common problem of universal drive shaft is the vibration and noise during driving. If the car is shaking and vibrating after inspection, check whether the universal joint forks at both ends of the drive shaft are installed on the same plane. Check whether the drive shaft has any traces of collision with ground obstacles, whether the shaft tube is bent, whether the balance sheet has fallen off, and if so, it should be corrected, repaired or replaced.

The phenomenon of drive shaft noise: In the condition of good technical condition of universal joints and expansion joints, the drive shaft makes periodic noises during driving. The faster the speed, the louder the noise, the more serious the car body shakes, and the numbness of the hand holding the steering wheel.


Reason analysis: 
① The drive shaft is bent or the shaft tube is sunken. 
②The drive shaft tube and the universal joint fork are not aligned or the drive shaft is not dynamically balanced. 
③The balance plate on the drive shaft is missing. 
④The expansion joint is not installed according to the mark, which will cause the transmission shaft to lose its balance and possibly cause the forks at both ends of the transmission shaft to not be on the same plane. 
⑤The fixing bolts of the middle support hanger or the connecting bolts of the universal joint flange plate are loose, which makes the position of the transmission shaft deviated. 
⑥The tightening method of the rubber clamping type intermediate support is improper, causing the front end of the intermediate transmission shaft to deviate from the original axis.


The phenomenon of universal joints and expansion joints: when the car starts or when the speed changes suddenly, the transmission device makes a noise. When the car slows down, the transmission device makes a "quack, quack" noise.


Reason analysis: 
①The universal joint bearing is loose due to wear or impact. 
②The expansion joint spline of the drive shaft is loose due to wear or impact. 
③The connecting bolts of the universal joint flange plate are loose.
