The invention provides a cooling structure of an in-wheel motor. The cooling structure of the in-wheel motor is arranged in a wheel of a vehicle wheel. The cooling structure of the in-wheel motor comprises: a rotating motor configured to rotate a hub to which a wheel is fixed; a knuckle that rotatably supports the hub and has a plurality of flow paths in the interior thereof through which a refrigerant for cooling the rotating electric machine flows; and a pump configured so as to circulate a refrigerant between the pump and the rotating electrical machine via a plurality of flow paths provided inside the knuckle.
本发明提供一种轮内电机的冷却结构,其是设置于车轮的轮内的轮内电机的冷却结构。所述轮内电机的冷却结构由:旋转电机,构成为使固定有轮的轮毂旋转;转向节,将轮毂以能够旋转的方式支承,并且在内部设有供冷却旋转电机的制冷剂流动的多个流路;及泵,构成为经由设置于转向节的内部的多个流路在与旋转电机之间使制冷剂循环,而构成。
