轮内电动机驱动装置
摘要：
本发明提供一种无需扩大搭载车辆的轮圈直径并且能够不受到动力线产生对的噪音的影响地取出信号线的轮内电动机驱动装置。在轮内电动机驱动装置(10)中，电动机部的电动机旋转轴从轮毂轴承部的轴线(O)沿车辆前后方向偏置地配置。轮内电动机驱动装置(10)包括壳体(70)，所述壳体(70)具有设置在与动力线的端子盒(90)不同的部分并向外部取出连接于电动机部的信号线的信号线取出口(83)，从轴线方向上观察，电动机旋转轴的轴心(M)和轮毂轴承部的轴心(O)之间的距离L与信号线取出口(83)和轮毂轴承部的轴心(O)之间的距离R之间的关系为R＜L/2。
摘要（英）：

The invention provides an in-wheel motor drive device which has no need to increase the wheel diameter of a mounting vehicle, and can take out a signal line so as not to receive the influence of noisegenerated from a power line as much as possible. In an in-wheel motor drive device 10, a motor rotational shaft of a motor part is arranged in an offset manner in the vehicle cross direction from anaxial line O of a wheel hub bearing part. The in-wheel motor drive device 10 includes a casing 70 which is arranged at a different position from a terminal box 90 of a power line, and has a signal line take-out port 83 for taking out a signal line connected to the motor part to the outside. The relation between a distance L between a shaft center M of the motor rotational shaft and a shaft centerO of the wheel hub bearing part and a distance R between the signal line take-out port 83 and the shaft center O of the wheel hub bearing part is R
