F81.35114.6111 Wheel reducer assy is a part of Shaanxi Automobile Heavy Truck Hande HDM300 drive axle system, which is mainly used to improve the driving force of the heavy truck and meet or modify the matching of the force of the entire transmission system. The reducer assembly is made up of a sun gear, a planetary gear, a ring gear and a planetary wheel carrier, and its working principle is to reduce the force of the front parts by reducing speed and increasing torque, and improve the ground clearance of the drive axle.

Structure

The wheel reducer is mainly composed of sun gear, planetary gear, ring gear and planetary wheel carrier. The sun gear is connected to the half shaft, the planetary wheel carrier is connected to the wheel, and the ring gear is connected to the axle housing. This structure allows power to be transmitted from the engine through the clutch, transmission and transfer case to the final reducer, and then to the wheel reducer and wheels, and finally drive the car

Application

Wheel reducers are widely used in trucks, large buses, off-road vehicles and other large industrial and mining vehicles. By increasing the gear transmission device for reducing speed and increasing torque, the driving force of the car can be improved, the force of the front parts can be reduced, and the load of the transmission, transmission shaft, final reducer, differential, half shaft and other components can be reduced and the size will be reduced.
