[0005] 本发明的轮毂和内齿圈是分体式的， 轮毂和内齿圈不需要采用同一种材料制成 ， 可使内齿圈采用钢制、 轮毂采用铝制， 从而降低本发明的轮毂的重量。 其中 ， 驱动电机的电机轴转动带动行星减速机构的太阳轮转动， 从而使与太阳轮啮 合的行星轮转动， 由于行星轮是与内齿圈啮合的， 行星轮转动可带动内齿圈转 动， 从而实现轮毂的转动。 由于刹车制动是作用在电机轴上的， 本发明的刹车 机构能以更小的力制动电机轴， 可选用施力较小的刹车机构， 以减少生产成本 ； 或在不更换刹车机构的情况下， 可更好地对电机轴进行刹车制动， 刹车更为 稳定， 可提高刹车强度。 其中， 驱动电机设置在轮毂内， 可使本发明的结构更 为紧凑。

[0009] 固定部凹槽的设置便于内齿圈的固定部与轮毂的定位和固定， 第一弧面可对固 定后的内齿圈进行周向上的位置保持。 其中， 固定部凹槽和固定部可形成有相 互对应的工艺孔， 内齿圈的固定部可通过螺钉等紧固件与凸台相固定； 内齿圈 的固定部的厚度可小于内齿圈的厚度， 以减少铸造用材。
[0010] 作为优选， 所述内齿圈外缘上形成有至少三个向外延伸的固定部， 所述固定部 呈环形均匀间隔设置， 所述凸台包括第一凸台和第二凸台， 所述第一凸台至少 为三个， 所述固定部凹槽设置在第一凸台上， 固定部与所述第一凸台一一对应 ， 所述内齿圈的固定部通过紧固件与所述第一凸台固定， 所述第一凸台的内壁 和第二凸台的内壁均形成有所述第一弧面。 固定部的数量和第一凸台的数量相 同， 固定部的数量大于或等于三个， 较只有两个固定部更为稳定； 可直接设置 三个固定部， 既降低内齿圈的铸造成本， 又可保证内齿圈与轮毂固定的稳定性 ， 又可降低重量， 同吋还可以减少装配用吋。 当轮毂和内齿圈较大吋， 可设置 多个第二凸台， 可在减少第一凸台体积和数量的情况下， 以保证内齿圈周向上 的限位固定。
