Baotou beiben accessory transmission shaft imbalance, while driving there will be a period of sound, the speed is faster, the greater the noise. Serious, can make the body trembling, cab vibration, hand steering wheel has numbness feeling. Because the body shaking, will result in the vehicle the parts of the loose, cause of the accident. Cab vibration, serious cause solder joints cracking.
The cause of vehicle buffeting is:
(1) drive shaft bending;
(2) the flange of the drive shaft and the position of the shaft pipe are skewed when welding;
(3) loosening of intermediate support fixed bolt;
(4) bearing deflection of intermediate bearing;
(5) Baotou beiben heavy duty truck accessories damaged joint, installation of substandard requirements;
(6) the original balance block falls off on the transmission shaft.
Transmission shaft imbalance, endangering safe driving. If the transmission shaft imbalance failure, the following methods can be used to determine:
The front wheel with wooden pad plugged, jack up the car to the side of the middle and rear drive axle; the engine, hang high gear, check the drive shaft vibration situation. Pay attention to the speed of view decline, if the vibration significantly increased, indicating the transmission shaft bending or flange skew.
Transmission shaft bending is bent tube, mostly due to overload caused by the car. Coaler due to overload, hanging, shaft bending, fracture failure occurs. If some cars plus trailers pulled more than and 60 tons of coal, transmission shaft due to overloading, excessive damage hanging. Although the middle support of the transmission shaft is strengthened, the strength of the flange fork is strengthened, but the fault of breakage is still occurred.
The replacement of Baotou beiben accessories shaft parts, after straightening, should balance checking, unbalance should conform to standard requirements. Technical condition of cardan shaft and hanger should also do a detailed inspection, such as the installation of substandard requirements, cross shaft and roller damage caused Songkuang, vibration, will make the shaft out of balance.
