The invention discloses a multi-gear variable-speed hub motor power assembly with an overspeed stage, which mainly comprises a fixed shaft, a hub, a motor stator, a motor rotor, a first planetary gear train, a second planetary gear train and three clutches, a motor rotor is connected to the rear portion of the fixing shaft through two identical bearings, the motor rotor is fixedly connected with a planet carrier of the first planetary gear train and an input sun gear of the second planetary gear train, the first clutch is fixedly connected with the fixing shaft, and the second clutch is fixedly connected with the fixing shaft. And the third clutch is fixedly connected with the second planetary system planet carrier and is in floating connection with the fixed shaft. Different gears are realized by changing the sequential engagement of the three clutches, so that the motor has three different transmission ratios, has the advantages of compact structure, simple implementation method and the like, has an overspeed function on a flat road, can improve the use efficiency of the motor, and has certain practical value.
