Wheel Reducer

The wheel-side reducer is mainly composed of sun gear, planetary gear, ring gear and planetary gear carrier. Generally, the active part of the sun gear is connected with the half shaft, the passive part of the planetary carrier is connected with the wheel, and the ring gear is connected with the axle housing. The wheel reducer is to improve the driving force of the car to meet or modify the force matching of the entire transmission system. The wheel-side reducer currently used is to meet the needs of the entire transmission system, and an additional set of gear transmission devices that reduce speed and increase torque. The power is transmitted from the Engine to the final drive of the front and rear axles via the clutch, transmission and transfer, and then from the output of the final drive to the wheel reducer and wheels to drive the car. In this process, the working principle of the wheel reducer is to transfer the speed and torque transmitted by the main reducer to the wheels after reducing the speed and increasing the torsion, so that the wheels can produce greater resistance under the reaction of ground adhesion. Driving force. Thereby reducing the stress on the front parts of the wheel reducer.
