The invention discloses a hub motor and discloses an electric bicycle with the hub motor, and the hub motor comprises a center shaft, a housing, a motor and a speed reducing mechanism. The motor is arranged in the shell and comprises a rotor and a stator, the stator is fixedly connected with the middle shaft, and the rotor is rotationally connected with the middle shaft through a third bearing; the speed reducing mechanism comprises a sun gear, a duplex planetary gear, an inner gear ring and a planet carrier, the sun gear is fixedly connected with the rotor, the duplex planetary gear is rotationally connected to the planet carrier and comprises a first planetary gear and a second planetary gear, the first planetary gear is meshed with the sun gear, and the second planetary gear is meshed with the inner gear ring; the diameter of the first planetary gear is larger than that of the second planetary gear, and the inner gear ring is fixedly connected with the shell. By adopting the duplex planetary gear speed reduction mechanism, secondary speed reduction can be realized, and the use requirements of high speed ratio and large load can be met under the condition that the overall size of the original hub is not increased.

    本发明公开了一种轮毂电机,并公开了具有轮毂电机的电动自行车,其中轮毂电机包括:中轴、外壳、电机和减速机构;电机设于外壳内,电机包括转子和定子,定子与中轴固定连接,转子通过第三轴承与中轴转动连接;减速机构包括太阳轮、双联行星齿轮、内齿圈和行星架,太阳轮与转子固定连接,双联行星齿轮转动连接于行星架,双联行星齿轮包括第一行星齿轮和第二行星齿轮,第一行星齿轮与太阳轮啮合,第二行星齿轮和内齿圈啮合,第一行星齿轮的直径大于第二行星齿轮的直径,内齿圈与外壳固定连接。通过采用具有双联行星齿轮减速机构,可实现二级减速,可在不增大原有轮毂整体体积的条件下可满足高速比大负载的使用要求。
