The invention discloses a shell assembly, an electric drive assembly and a vehicle, the shell assembly is used for the electric drive assembly, the electric drive assembly comprises a power part and a speed change part which are arranged in the shell assembly, and the shell assembly comprises a separation part, a first shell, a second shell, a flow guide part and a heat exchange part. The separation part is provided with a first through hole and a second through hole. The first shell and one side of the separation part jointly define a driving cavity suitable for containing a power component. And the second shell and the other side of the separation part jointly define a speed change cavity. One end of the flow guide part is communicated with the first through hole, and the other end of the flow guide part is communicated with the variable-speed cavity; the heat exchange part is suitable for circulation of a second heat exchange medium and exchanges heat with the flow guide part. The first heat exchange medium in the speed change cavity is suitable for entering the flow guide part and entering the driving cavity through the first through hole, and the first heat exchange medium in the driving cavity is suitable for being guided into the speed change cavity through the second through hole. Due to the fact that the first heat exchange medium is not guided out of the shell assembly, the risk of leakage of the first heat exchange medium is reduced.
本发明公开了一种壳体组件、电驱动总成及车辆,壳体组件用于电驱动总成,电驱动总成包括设于壳体组件内的动力部件以及变速部件,壳体组件包括分隔部、第一壳体、第二壳体、导流部以及换热部。分隔部设有第一通孔以及第二通孔。第一壳体与分隔部的一侧共同限定出适于容纳动力部件的驱动腔。第二壳体与分隔部的另一侧共同限定出变速腔。导流部设于变速腔,且一端连通第一通孔、另一端连通变速腔。换热部适于流通第二换热介质,换热部与导流部进行热交换。其中,变速腔内的第一换热介质适于进入导流部内并由第一通孔进入驱动腔,驱动腔内的第一换热介质适于由第二通孔导入变速腔。由于第一换热介质不导出壳体组件,降低了第一换热介质泄露的风险。
