The unevenness of the drive shaft of a car will present a periodic sound during driving. The faster the driving speed, the louder the noise.When it is heavy, it can make the body tremble, the cab will vibrate, and the steering wheel will feel numb.Because the body trembles, various parts of the vehicle will become loose and cause chaos.Vibration in the cab will cause cracks in the solder joints.So what are the reasons for vehicle vibration?

　　Because of overloading and overhanging of coal-carrying vehicles, there are many problems with tortuous and broken drive shafts.If some trucks and trailers are used to transport more than 60 tons of coal, the drive shaft will be seriously damaged due to overloading and overhanging.Although the drive shaft support is strengthened, and the strength of the flange fork is strengthened, it still shows the problem of fracture and destruction.

　　After replacing the transmission shaft components, after straightening, the balance introspection should be stopped, and the uneven balance should meet the requirements of the standard.The technical status of the universal joint fork and the drive shaft hanger should also be reviewed in detail. For example, due to different requirements of the device, the cross shaft and the roller are damaged and cause looseness and vibration, which will also make the drive shaft fall out of balance.
