2 so that the left and right driving the axial relative position of the wheel is fixed

3 driving the car, to withstand a variety of driving wheels came opposite force, force and torque, and passed through the suspension to the frame

The drive axle housing can be divided into the overall segmented two categories.

The integral bridge shell is the axle housing and the main reducer housing are manufactured separately, the two are connected together by bolts. The advantages of the structure is in check the main gear box and differential position or disassembly without the drive axle removed from the car, and thus more convenient maintenance, generally for various types of vehicles.

Segmented axle housing axle housing and the main gear box shell cast one, and is generally divided into two sections by bolts fused.
