The function is to fold the power from the universal transmission device into a 90° Angle, change the direction of force transmission, and reduce the speed by the main reducer, increase the torque, and then distribute it to the left and right half axles and driving wheels through the differential.
The drive axle is at the end of the powertrain, and its basic functions are as follows: (1) the engine torque from the universal transmission device is transmitted to the driving wheels through the main reduction tire, the differential, the half axle, etc., to achieve a decrease in speed and increase in torque; (2) through the main reducer bevel gear pair to change the direction of torque transmission; (3) Realize the difference of wheels on both sides through the differential to ensure that the inner and outer wheels are steering at different speeds.
