The present invention relates to a lubrication system for an in-wheel motor power train. The system includes: a housing having one side coupled to a motor, supporting a wheel on an outer circumference surface and having an internal space therein; an input gear and an output gear installed in the housing; two medium gears integrated as a first gear geared to the input gear and a second gear geared to the output gear while having a pitch circle diameter different from the first gear form a concentric axis; a pump gear geared to the input gear; a bearing plate supporting the input gear, the output gear and the medium gears on one side of the housing to be rotatable; a cover plate formed to constitute a part of a lubrication pump operated by the pump gear; and a first oil supply part formed by a mid-plate and the cover plate so as to promote the lubrication of one side of the medium gears and the output gear. Therefore, the system is capable of ultimately securing the stable durability for an in-wheel motor power train.

    본 발명은 일측에 모터가 결합되고 외주면에서 휠을 지지하며 내부에 공간을 구비한 하우징과; 상기 하우징 내에 설치된 입력기어 및 출력기어와; 상기 입력기어에 치합되는 제1기어와, 상기 제1기어와 다른 피치원지름을 가지고 상기 출력기어에 치합되는 제2기어가 동심축을 이루어 일체로 형성된 2개의 매개기어와; 상기 입력기어에 치합된 펌프기어와; 상기 하우징의 일측에서 상기 입력기어, 출력기어 및 매개기어를 회전 가능하게 지지하는 베어링플레이트와; 상기 펌프기어에 의해 구동되는 윤활펌프의 일부를 구성하도록 형성된 커버플레이트와; 상기 출력기어 및 매개기어의 일측 윤활을 도모하도록, 상기 커버플레이트와 미드플레이트에 의해 형성된 제1오일공급부를 포함하여 구성된다.
