The invention discloses a vehicle three-gear variable-speed hub driving system, which belongs to the technical field of vehicle electric driving and comprises a hub motor, a first planet row, a second planet row, a third planet row, a clutch and two brakes. The first planet row, the second planet row and the third planet row are coaxially arranged in sequence; the first planet carrier serves as the input end of the driving system and is coaxially connected with a rotor of the hub motor. The second sun gear is coaxially connected with one output piece of the first planet row, the third sun gear is coaxially connected with the second sun gear, and the third gear ring is coaxially connected with the second planet carrier; the third planet carrier is the output end of the driving system; the clutch is connected between the output piece of the first planet row and the second planet carrier; and the two brakes are respectively used for braking the second gear ring and the third gear ring. Through the integrated design of the brake and the planetary transmission, the neutral gear and braking functions are achieved while the low gear, the middle gear and the high gear are achieved, so that the hub driving system is high in structural integration degree and stable in gear shifting.

    本发明公开了一种车辆三档变速轮毂驱动系统,属于车辆电驱动技术领域,包括轮毂电机、第一行星排、第二行星排、第三行星排、离合器及两个制动器;第一行星排、第二行星排及第三行星排依次同轴排布;第一行星架作为驱动系统的输入端,与轮毂电机的转子同轴连接;第二太阳轮与第一行星排的一个输出件同轴连接,第三太阳轮与第二太阳轮同轴连接,第三齿圈与第二行星架同轴连接;第三行星架为驱动系统的输出端;离合器连接在第一行星排的输出件和第二行星架之间;两个制动器分别用于制动第二齿圈和第三齿圈。本发明通过制动器与行星变速器一体化设计,实现低、中、高三种档位的同时,具备空档和制动功能,使得轮毂驱动系统的结构集成度高、换档平稳。
