    • A motor-driven wheel driving apparatus has a wheel bearing, a planetary reduction gear, a driving section with an electric motor to drive the planetary reduction gear, and a rotation member. The wheel bearing includes a wheel hub, an inner ring, an outer member and double row rolling elements arranged between the inner and outer raceway surfaces. The planetary reduction gear includes an input element, a stationary element, a plurality of planetary, and an output element to rotatably support the planetary elements relative to a connecting shaft. The driving section forming the electric motor has a stator housing, a stator portion contained within the stator housing, and a rotor portion secured on the rotation member arranged opposite to the stator portion via a predetermined air gap. The connecting shaft is removably and torque-transmittably connected to the wheel hub. The connecting shaft is adapted to drive the wheel by transmitting the rotation of the electric motor to the wheel hub via the planetary reduction gear.
    • 电动轮驱动装置具有车轮轴承,行星减速齿轮,具有用于驱动行星减速齿轮的电动机的驱动部和旋转部件。 车轮轴承包括轮毂,内圈,外部构件和布置在内侧和外侧轨道表面之间的双列滚动元件。 行星减速齿轮包括输入元件,固定元件,多个行星齿轮和输出元件,以相对于连接轴可旋转地支撑行星元件。 形成电动机的驱动部分具有定子壳体,容纳在定子壳体内的定子部分,以及固定在与定子部分相对的旋转部件上的转子部分。 连接轴是可拆卸的,扭矩可传递地连接到轮毂。 连接轴适于通过行星减速齿轮将电动机的旋转传递到轮毂来驱动车轮。
