The invention discloses a shell assembly, an electric driving system and a vehicle, and solves the technical problems that an existing electric driving system externally provided with a motor controller is large in size and not beneficial to whole vehicle carrying. The shell assembly comprises two shell units, namely a shell main body and an upper shell, the shell main body is provided with a motor cavity for accommodating the motor and a circulating groove for circulating cooling liquid, the upper shell is arranged on the shell main body, and a control cavity for accommodating the control assembly is defined by the upper shell and the shell main body. The circulation groove of the shell body is of an open structure, the groove opening of the circulation groove faces the control cavity, the control assembly can be in direct contact with cooling liquid in the cooling flow channel, and effective cooling is achieved. The housing assembly provided by the invention deeply integrates the housing of the motor and the control assembly thereof, and integrates the controller cooling assembly and the housing in the housing assembly, thereby reducing the size of the assembly, facilitating the carrying, reducing the number of controller cooling parts, and reducing the cost.

    本申请公开了一种壳体总成、电驱动系统和车辆,解决现有外装电机控制器的电驱动系统体积大,不利于整车搭载的技术问题。壳体总成包括壳体主体和上壳体两个壳体单元,其中壳体主体设有用于容纳电机的电机腔和供冷却液流通的流通槽,上壳体设置于壳体主体上,上壳体与壳体主体合围成用于容纳控制组件的控制腔。壳体主体的流通槽为开放式结构,流通槽的槽口朝向控制腔,控制组件能够直接与冷却流道中的冷却液直接接触,有效冷却。本申请提供的壳体总成深度集成了电机及其控制组件的壳体,并且将控制器冷却组件及外壳集成在壳体总成中,减小总成体积利于搭载,同时减少控制器冷却部件,降低成本。
