The drive axle generally consists of the main reducer, differential, wheel drive device, and drive axle housing. Its function is to bend the power transmitted by the universal transmission device over a 90 ° angle, change the direction of force transmission, and reduce the speed and increase the torque by the main reducer. After that, it is distributed to the left and right half shafts and drive wheels through the differential.
Function
The drive axle is located at the end of the power transmission system, and its basic function is to: ① transmit the engine torque transmitted by the universal transmission device to the driving wheels through the main reducer, differential, half shaft, etc., to achieve deceleration and increase torque; ② Changing the direction of torque transmission through the bevel gear pair of the main reducer; ③ By using the differential, the differential between the two wheels ensures that the inner and outer wheels turn at different speeds; ④ Load bearing and force transmission are achieved through the axle housing and wheels.
Drive axles can be divided into two categories: non disconnecting and disconnecting.
According to the structural form, the drive axle can be divided into central single-stage reduction drive axle, central two-stage reduction drive axle, central single-stage, and wheel side reduction drive axle.
