The invention discloses a three-gear variable-speed hub motor power assembly with large torque, which is characterized by comprising a motor, a left planetary gear train, a right planetary gear train, a first brake, a second brake, a third brake and a hub, the first brake and the second brake are fixedly connected to the inner wall of a case, the third brake is fixedly connected to a motor shaft, and the hub is fixedly connected to the motor shaft. The three brakes are matched with one another to achieve the gear switching function. According to the invention, three forward gears, a neutral gear and a parking gear can be met, wherein the three forward gears comprise a large-torque gear; meanwhile, the transmission structure has the advantages of being compact in structure, simple in gear shifting mode, high in transmission efficiency, low in assembly precision requirement and the like, provides a new scheme reference for an existing transmission structure of a hub motor of a load-carrying electric vehicle, and has good use value and application prospects.

    本发明公开了一种含大扭矩的三档变速轮毂电机动力总成,其特征包括电动机、左侧行星轮系、右侧行星轮系、第一制动器、第二制动器、第三制动器和轮毂,第一制动器、第二制动器固联于机箱内壁,第三制动器固联于电机轴上,所述三个制动器通过相互配合实现挡位切换功能。本发明可满足三个前进档,一个空挡和一个驻车档,其中三个前进档中包含一个大扭矩挡位;同时具有涉及结构紧凑、换挡方式简单、传动效率高和装配精度要求低等特点,对现有的载重电动车轮毂电机的传动结构提供了一种新的方案参考,具有较好的使用价值和应用前景。
