본 발명은 전기자동차의 액슬장치에 관한 것으로서 보다 상세하게는 구동모터와 감속기를 하나의 유닛으로 패키징하여 전체적인 사이즈를 최소화시킨 전기자동차의 액슬장치에 관한 것이다.본 발명의 전기자동차의 액슬장치(100)는 구동모터(110)와, 상기 구동모터와 결합되어 상기 구동모터의 회전속도를 2차에 걸쳐 감소시키는 감속기(120)와, 상기 감속기에 결합되어 상기 구동모터와 감속기를 일체로 지지하는 액슬빔(130)과, 상기 감속기에 결합된 액슬샤프트(140)와, 상기 액슬샤프트를 통해 상기 감속기로부터 감속된 동력을 전달받아 휠을 회전시키는 휠허브(150)를 포함한다.

    The present invention relates to an axle device for an electric vehicle and, more particularly, to an axle device for an electric vehicle, which minimizes the overall size by packaging a drive motor and a reducer as one unit. According to the present invention, the axle device (100) for an electric vehicle comprises: a driving motor (110); a reducer (120) coupled to the driving motor to reduce the rotational speed of the driving motor over a second time; an axle beam (130) coupled to the reducer to integrally support the driving motor and the reducer; an axle shaft (140) coupled to the reducer; and a wheel hub (150) which rotates the wheel by receiving the decelerated power from the reducer through the axle shaft.
