The invention discloses an electrically-driven wheel integrating a planetary reducer and a high-torque-density hub motor, and aims to solve the problem that how to integrate a hub motor, a transmission system and a brake system into a wheel. The electrically-driven wheel is characterized in that a driving end cover (36) is an embedded structure end cover recessed towards the direction of a motor rotor bracket, a hollow bush (24) is fixedly connected to the outer side of the center hole of the driving end cover (36), a main bearing inner ring (25) is connected to the outer side surface of the hollow bush in a sleeved mode, a wheel rim (38) is connected to a main bearing outer ring (26), a rotary transition sleeve (30) is arranged in the cavity of the hollow bush (24), one end of the inner ring of the rotary transition sleeve is connected with the driving end shaft extension (31) of a wheel hub motor rotating shaft (7), the other end of the inner ring of the rotary transition sleeve is connected with a sun gear shaft (32) of a planetary reducer, a sun gear (33) is meshed with a planet gear (34), and the planet gear is meshed with the wheel rim (38).

    本发明公开了一种行星减速器与高转矩密度轮毂电机集成一体的电驱动车轮,解决了如何将轮毂电机、传动系统和刹车系统集成于车轮一体的问题;驱动端端盖(36)为向电机转子支架方向凹陷的嵌入式结构端盖,在驱动端端盖(36)的中心孔外侧固定连接有空心套筒(24),在空心套筒的外侧面上套接有主轴承内圈(25),在主轴承外圈(26)上连接有轮辋(38),在空心套筒(24)腔内设置有旋转过渡套(30),旋转过渡套的内圈的一端与轮毂电机转轴(7)的驱动端轴伸(31)连接,在旋转过渡套的内圈的另一端上连接有行星减速器的太阳轮轮轴(32),在太阳轮(33)上啮合有行星轮(34),行星轮与轮辋(38)啮合。
