Internal structure of drive axle
Drive axle assembly is one of the most important spare parts of transmission system, its main function is
reduce rotation speed from gear box and increase torque, and make wheels at both sides having speed
difference. Besides, it also plays the role of bearing and transmitting. Drive axle assembly of loader is mainly
composed of shell, main drive (including differential mechanism), semiaxis, hub reduction gear, brake caliper
assembly and other parts. Of which, the parts having reduction and differential function is main driver and
hub reduction gear; power transmission between main drive and hub reduction gear is realized through
semiaxis, multiple spline at both sides of semiaxis and axle shaft gear of differential mechanism and sun
gear of hub reduction gear mesh with each other to realize power connection between main drive and hub
reduction gear.
