Solution | The differential housing Solution

The function of the differential is to meet the requirement of different speeds of the wheels on both sides of the car during turning. The differential housing is an important protective structure of the differential, therefore, its material and structure must be able to withstand the impact and vibration from the vehicle's heavy load and complex road conditions. The differential housing blank is a casting, commonly made of ductile iron or steel. The main processing techniques include rough and finishing turning of the bearing collar, outer surface and end face, machining of the inner cavity and half-shaft gear surface, and machining of the axle hole and other holes.
