The drive axle is composed of multiple components, including the final drive, differential, wheel transmission and drive axle housing. The main function of the drive axle is to bend the power from the universal transmission by 90 degrees and change the direction of force transmission. At the same time, it reduces the speed of the final drive, increases the torque, and distributes the torque to the left and right through the differential. Half shaft and drive wheel.

As the end of the power transmission system, the drive axle plays an important role. It can transmit the engine torque from the universal transmission to the driving wheels through the main reducer, differential, half shaft, etc., thereby reducing the speed and increasing the torque. In addition, it can also change the direction of torque transmission through the bevel gear pair of the main reducer. More importantly, the drive axle uses a differential mechanism to realize the differential action of the two wheels to ensure that the inner and outer wheels rotate at different speeds.

In short, the role of the drive axle is to transmit the power generated by the engine to the driving wheels of the vehicle to realize the driving of the vehicle. Through the cooperative work of multiple components, the torque of the engine can be fully utilized and the power transmission process of the vehicle is more stable.
