YT260-320 Axle

The drive axle is a mechanism located at the end of the drive train that changes the speed and torque from the transmission and transmits them to the drive wheels. The drive axle is generally composed of the main reducer, differential, wheel drive device and drive axle shell, etc., and the steering drive axle also has a constant velocity universal joint. In addition, the drive axle must also withstand vertical, longitudinal and lateral forces, as well as braking torque and reaction forces acting between the road surface and the frame or body.
The drive axle is at the end of the power transmission system, and its basic functions are:

(1) transmitting the engine torque from the universal transmission device to the drive wheel through the main reducer, differential, half shaft, etc., to reduce speed and increase torque;

(2) Change the transmission direction of torque through the bevel gear pair of the main reducer;

(3) The differential realizes the differential of the wheels on both sides to ensure that the inner and outer wheels steer at different speeds;

(4) The bearing and torque transmission functions are realized through the bridge shell and wheels.
