The invention discloses an inverted three-wheeled electric vehicle rear wheel driving device which comprises a wheel shaft, a needle bearing, a deep groove ball bearing, an end cover, a rotor, a stator winding, a second deep groove ball bearing, a gear B, a gear C, a spline hollow shaft, a rotary induction magnetic ring and a brake disc. A stator winding is arranged outside the rotor, the stator is fixed to the motor shell, the outer side of the rotor is connected with an end cover through a deep groove ball bearing and a third framework oil seal, a gear A is machined at the tail end of the motor hollow shaft and meshed with a gear C through a gear B, the gear C is connected with a hub through a spline hollow shaft, and the hub is matched with a brake pad. And a rotary induction magnetic ring is also arranged on the axle on the outer side of the brake pad. The device is reasonable in structural design, stable in operation, low in working noise and small in impact load; the transmission system has no obvious structure deformation during operation, and the device works stably and is suitable for long-term operation; a high transmission ratio can be achieved, and the mechanical efficiency is high. The chassis occupies small space, and the vehicle body layout is convenient.

    本发明公开了一种倒三轮电动车后轮驱动装置,包括轮轴、滚针轴承、深沟球轴承、端盖、转子、定子绕组、第二深沟球轴承、B齿轮、C齿轮、花键空心轴、旋转感应磁圈和刹碟片,轮轴上通过滚针轴承设置有电机空心轴,电机空心轴外套接有转子,转子的外部设置有定子绕组,定子与电机外壳固定,转子的外侧通过深沟球轴承、第三骨架油封与端盖连接,电机空心轴的末端加工有A齿轮,A齿轮通过B齿轮与C齿轮相啮合,C齿轮通过花键空心轴与轮毂相连,轮毂与刹车片配合,刹车片外侧的轮轴上还设置有旋转感应磁圈。本发明结构设计合理,运转平稳,工作噪声低,冲击载荷小;传动系统运转时结构无明显变形,装置工作稳定,适合长期运行;可以达到较高传动比,机械效率高。底盘空间占用小,方便车体布局。
