The invention provides a dual-motor power assembly with an integrated shell and an electric vehicle, the dual-motor power assembly comprises two middle shells and a middle partition plate, and a containing cavity of each middle shell is used for containing a speed reducer and a motor. The middle partition plate comprises two partition plate installation faces, the two partition plate installation faces are opposite, and each partition plate installation face is used for being fixedly connected with one middle shell. Each partition plate installation face comprises two partition plate oil holes, and the directions of the partition plate oil holes of the two partition plate installation faces are opposite. The two partition plate oil holes in each partition plate installation face communicate with each other through one inner oil channel of the middle partition plate, and the two partition plate oil holes in each partition plate installation face communicate with one heat exchanger and one containing cavity through the two inner oil channels of one middle shell correspondingly. According to the dual-motor power assembly, the two independent oil channels are formed in the middle partition plate to independently supply oil to the containing cavities of the two middle shells, the situation that cooling oil is not evenly distributed in the dual-motor power assembly is relieved, and therefore the working efficiency of the dual-motor power assembly is improved.

    本申请提供一种具有集成壳体的双电机动力总成及电动车,双电机动力总成包括两个中间壳体和中隔板,每个中间壳体的容纳腔用于容纳减速器和电机。中隔板包括两个隔板安装面,两个隔板安装面相背,每个隔板安装面用于固定连接一个中间壳体。每个隔板安装面包括两个隔板油孔,两个隔板安装面的隔板油孔的朝向相背。每个隔板安装面的两个隔板油孔通过中隔板的一个内部油道连通,每个隔板安装面的两个隔板油孔分别通过一个中间壳体的两个内部油道连通一个换热器和容纳腔。本申请通过在中隔板形成两个独立的油道以对两个中间壳体的容纳腔进行独立供油,缓解冷却油在双电机动力总成中分布不均的情况,从而提升双电机动力总成的工作效率。
