    • A vehicular electric drive system comprises: an electric motor operatively connected to drive wheels so that the drive wheels are driven by said electric motor; a hydraulically operated clutch configured to place a power transmitting path between said electric motor and said drive wheels in a selected one of a power transmitting state and a power cutoff state; a gear mechanism disposed between said hydraulically operated clutch and said drive wheels, to reduce a speed of a rotary motion of said electric motor; a first chamber accommodating said electric motor and said hydraulically operated clutch; a second chamber accommodating said gear mechanism; a partition wall disposed so as to isolate said first chamber and said second chamber from each other; a connecting hole formed on said partition wall through which said hydraulically operated clutch and said gear mechanism are operatively connected to each other; an oil seal fitted in said connecting hole, to restrict flows of an oil through said connecting hole; an oil pump provided to deliver the oil required within said first chamber; and another independent oil supply mechanism which does not use said oil pump and which is provided to supply the oil to said second chamber.
    • 一种车辆电驱动系统,包括:电动机,其可操作地连接到驱动轮,使得所述驱动轮由所述电动机驱动; 一种液压操作的离合器,其被配置为在所述电动机和所述驱动轮之间的动力传递路径中以选定的动力传递状态和动力切断状态中的一个放置; 设置在所述液压操作的离合器和所述驱动轮之间的齿轮机构,以减小所述电动机的旋转运动的速度; 容纳所述电动机和所述液压操作离合器的第一室; 容纳所述齿轮机构的第二腔室; 分隔壁,其被设置成将所述第一室和所述第二室彼此隔离; 形成在所述分隔壁上的连接孔,所述液压操作离合器和所述齿轮机构通过所述连接孔彼此可操作地连接; 安装在所述连接孔中的油封,以限制油通过所述连接孔的流动; 设置用于输送所述第一室内所需的油的油泵; 以及不使用所述油泵并且被提供以将油供应到所述第二室的另一独立供油机构。
