电动轮毂及驱动轮
摘要：
本发明涉及一种电动轮毂和一种使用该电动轮毂的驱动轮。电动轮毂包括轮毂和内齿圈，内齿圈与轮毂为分体结构，内齿圈与轮毂被相互同轴固定在一起并同步转动，轮毂具有中空的内腔，轮毂的内腔设置有驱动电机，驱动电机包括机壳和电机轴，机壳外壁与轮毂内腔的内壁之间具有间隙，电机轴一端通过行星减速机构与所述内齿圈配合，所述电机轴的另一端设置有电磁刹车机构。本发明具有可降低驱动轮重量、降低生产成本的优点，本发明可避免轮胎相对轮毂打滑，驱动轮的刹车性能更好，本发明的安全性能较高，本发明结构紧凑，可使使用了本发明驱动轮的轮椅车或代步车体积更小、重量更低。
摘要（英）：

An electric wheel hub, comprising a wheel hub (1) and an inner ring gear (2). The inner ring gear and the wheel hub are fixed coaxially and rotate synchronously. A drive motor is provided within an inner cavity of the wheel hub. A motor shaft of the drive motor has one end fitting to the inner ring gear via a planetary reduction mechanism, and the other end provided with an electromagnetic braking mechanism. The wheel hub of the present invention has advantages of reducing the weight of a drive wheel, lowering manufacturing costs, etc. Also disclosed is a drive wheel.
