What is the working principle of the car winch?

For automotive electric winches, its power source is automotive batteries. The power of the car battery is used to drive the motor. Then the motor can drive the drum to rotate, the drum continues to drive the drive shaft, and the drive shaft drives the planetary gear mechanism to generate strong torque. Then, this powerful torque will be transmitted to the drum and then continue to drive the winch. There is a clutch between the motor and the reducer that can be manually controlled. The brake unit is inside the drum, and when the winch of the car winch is tightened, the drum is automatically locked.

For a typical winch motor, its power is limited, typically only 3 to 4 kW. Therefore, laymen are very skeptical about how such a small power can drag a car? In fact, the mystery lies in the reducer. This gadget can transform this smaller power into a powerful power. Most of the winches use planetary gears as the speed reducer, and the deceleration and twisting effect is very significant, and the gear has more contact points, uniform force, and the service life will be greatly extended.
