Common edge reducer assembly main reason is the lack of serious wear and tear of lubricating oil, lubricating oil metamorphism and deformation of drive axle. The gear wear is the most important. Gear wear is mainly caused by the above reasons, the following detailed reasons:

1, while reducing lubricating assembly is self-contained, should always check and add, the wheel side reducer each side filling amount is 2L, if the wheel side reducer is short of oil, oil is not enough, resulting in gear lubrication is insufficient, because the car did not stop running, causing serious wear planetary ring gear and planetary gear surface. The oil is not enough, the planet gear shaft and planetary gear inner hole wear, bearing damage, resulting in planetary gear inside the gear tooth surface will produce wear.

2, due to various reasons caused the drive axle bending deformation, destroy the edge reducer assembly of the gear tooth gap, caused by the wear of gears. Edge reducer assembly at work, half shaft to rotate round the sun, in not differential, differential planetary gear rotates around the sun and planet gear wheel and rotate together. Because the drive axle bending deformation, destruction of the sun gear and planet gear tooth clearance normal, leading to the sun wheel, a planetary gear, planetary gear ring gear surface abrasion. Because the driving bridge deformation, a sun wheel position change and planetary gear is not normal, the gap change caused by a planet gear shaft and bearing damage.

3, while reducing the processing quality of assembly and installation quality problems caused by the gear tooth surface abrasion. In order to ensure the normal operation of the wheel reducer, every time a maintenance check edge reducer assembly oil surface, less timely supplement. Each driving 12000KM two maintenance should be cleaning the gear chamber and oil, wheel rim seal (190*220*5) damaged should be replaced promptly, prevent the wheel side reducer oil starvation damage. Oil also can not gado gado, will cause the temperature is high, make the oil deterioration and damage to the normal position in gear, as well. In assembling the wheel accelerator must be careful, in accordance with the provisions of assembly, prevent the gap change.
