The present invention relates to an installation structure for a differential gear and a reducer of an electric vehicle, and more specifically, to an installation structure for a differential gear and a reducer for transmitting a driving force generated by a motor connected to a battery to an output shaft in a powertrain for an electric vehicle in which a reducer housing and a motor housing are formed in the same shape and an outer housing is formed by coupling the same housings. A position, a configuration, and a support form of a gear cover and a middle cover installed in the same housing regardless left and right sides are provided. Since the housing has no directionality due to the above configuration, it can be used without any distinction between the left and right sides so that the burden caused by inventory products can be reduced when manufacturing products. A reducer portion is installed in a reducer housing and a motor is installed in a motor housing so that both housings can be finally assembled. Because both sides of the housing are the same, the manufacturing process is reduced and the assembling process is simplified, which is a useful to reduce the time and costs when manufacturing the products.

    본 발명은 전기자동차의 차동기어 및 감속기의 설치구조에 관한 것으로, 더욱 자세하게는 감속기 하우징과 구동 모터 하우징이 동일한 형태로 구성되어 있으며, 동일한 하우징의 결합으로 외부 하우징이 구성되는 전기자동차용 파워트레인에 있어서, 배터리가 연결된 구동 모터에 의해 발생한 구동력을 출력축으로 전달하기 위한 차동기어와 감속기의 설치구조를 나타내며, 좌측, 우측 구분 없이 동일한 하우징 내부에 설치하기 위한 기어 커버와 미들 커버의 위치와 구성 및 지지형태를 나타내고 있으며, 상기와 같은 구성으로 인하여 하우징에 방향성이 없기 때문에 좌측, 우측 구분 없이 사용이 가능하고 이는 제품을 생산할 때 재고에 의한 부담이 줄어드는 장점이 있으며, 감속기 하우징에 감속부가 설치되고 구동 모터 하우징에 구동 모터가 설치되어 양측 하우징을 최종 조립만 하면 되는 형태이고, 하우징이 양쪽이 같기 때문에, 생산 공정이 줄어들고 조립이 간소화 되어 제품을 생산하기 위한 시간과 원가를 줄일 수 있는 유익한 발명이라 할 수 있다.
