Liugong 862H Planetary gear 41A0738，with 27 teeth, together with the sun gear shaft 41A0739 41A0887, internal ring gear, wheel rim planetary carrier, etc., constitutes the wheel rim reducer assembly to achieve secondary deceleration on the wheel rim and increase torque.
The working principle of the wheel reducer is based on the tooth ratio principle of the gear. ‌It is designed with different number of gears and gear sizes, ‌ making the speed of the input shaft and the speed of the output shaft different, ‌ thus realizing the adjustment of the car's driving speed and steering control. ‌This device is widely used in trucks, ‌large buses, ‌off-road vehicles and some other large industrial and mining vehicles, ‌to ensure that the transmission, ‌drive shaft and ‌main reducer are maintained under the same overall transmission ratio. , ‌ differential, ‌ half shaft and other components, the load is reduced, the ‌ size becomes smaller, and the drive axle obtains a larger ground clearance and other advantages. ‌The wheel reducer is closely related to the speedometer and differential. ‌The power is transmitted to the two driving wheels through the differential, ‌plays a role in the movement of the wheels,‌provides guarantee for the driving of the car. ‌In addition,‌operating the wheel reducer‌can move the maximum output point of the engine torque to the speed point where the vehicle is working,‌thereby avoiding the situation of the vehicle speed being too slow or too fast,‌improving the stability and passing performance of the vehicle. sex
