An in-wheel drive system and a motor vehicle. The in-wheel drive system comprises a hub (2), a drive motor (3), a rotor carrier (4) fixed to a rotor (32) on a radial inner side of the rotor (32) of the drive motor (3), and planetary gear reducers (5, 6). The planetary gear reducers (5, 6) comprise sun gear shafts (51, 61) fixed to the rotor carrier (4) on a radial outer side of the hub (2), planetary gears (52, 62) engaged with the sun gear shafts (51, 61) on radial outer sides of the sun gear shafts (51, 61), a gear ring (50) engaged with the planetary gears (52, 62) on radial outer sides of the planetary gears (52, 62), and planetary gear carriers (53, 63) supporting the planetary gears (52, 62) and fixed to the hub (2).
一种轮内驱动系统和机动车,轮内驱动系统包括轮毂(2)、驱动电机(3)、在驱动电机(3)的转子(32)的径向内侧与转子(32)固定的转子支架(4)和行星齿轮减速器(5、6);行星齿轮减速器(5、6)包括在轮毂(2)的径向外侧固定于转子支架(4)的太阳轮轴(51、61)、在太阳轮轴(51、61)的径向外侧与太阳轮轴(51、61)啮合的行星齿轮(52、62)、在行星齿轮(52、62)的径向外侧与行星齿轮(52、62)啮合的齿圈(50)和支撑行星齿轮(52、62)并固定于轮毂(2)的行星齿轮架(53、63)。
