According to the present invention, an axle apparatus with an integrated drive motor comprises: an in-wheel motor which is mounted on an inner side of a wheel, and has a power transfer shaft on which an input gear is mounted; a reduction gear geared with the input gear to decelerate power transferred from the in-wheel motor; a housing having a gear space chamber to position the input gear of the in-wheel motor and the reduction gear, and an oil collection chamber isolated from the gear space chamber, wherein oil is circulated to the gear space chamber, and the power transfer shaft of the in-wheel motor is connected thereto to circulate oil; and an oil guide positioned and separated from the reduction gear in the gear space chamber of the housing, and guides oil scattered when the reduction gear rotates to allow the oil to flow to the oil collection chamber. The oil scattered by the reduction gear flows to the oil collection chamber and then is supplied to the in-wheel motor by the power transfer shaft.

    본 발명에서는 휠 내측에 장착되고, 인풋기어가 결합되는 동력전달축이 구비된 인휠모터; 상기 인풋기어와 치합되어 인휠모터로부터 전달되는 동력을 감속시키는 감속기어; 상기 인휠모터의 인풋기어와 감속기어가 위치되도록 기어 공간실이 형성되며, 기어 공간실과 격리되되 기어 공간실과 오일이 순환되고, 인휠모터의 동력전달축이 상호 오일이 순환되도록 연결되는 오일포집실이 형성된 하우징; 및 상기 하우징의 기어 공간실에서 감속기어와 이격되어 위치되고, 감속기어의 회전시 비산되는 오일을 가이드하여 오일포집실로 유동되도록 하는 오일가이드;를 포함함으로써 감속기어에서 비산된 오일이 오일포집실로 유동된 후 동력전달축을 통해 인휠모터에 공급되는 것을 특징으로 하는 구동모터 일체형 액슬 장치가 소개된다.
