The invention provides a power assembly, a dual-motor power assembly and an electric vehicle. A shell of the power assembly comprises a motor groove, a speed reducer groove and an electric control groove, the motor groove accommodates a stator and a rotor of a motor, the speed reducer groove accommodates a gear set and a transmission piece of a speed reducer, and the electric control groove accommodates an electrical assembly of a controller. The electrical assembly outputs a three-phase current to the winding of the stator through the transmission member. The motor is in transmission connection with wheels through reducers. The motor groove and the electric control groove are arranged on the same side of the speed reducer groove in the axial direction of the motor. One communicating hole of the shell is used for communicating the speed reducer groove with the electric control groove, and the shell is placed into the other communicating hole to communicate the speed reducer groove with the motor groove. The transmission piece comprises two cylinder penetrating pieces and a copper bar, and one cylinder penetrating piece is used for penetrating one communicating hole and electrically connecting one end of the copper bar with the electrical assembly. And the other cylinder penetrating piece is used for penetrating through the other communicating hole and electrically connecting the other end of the copper bar and the winding of the stator. Miniaturization of a power assembly is facilitated, and the space of an electric vehicle is saved.

    本申请提供了一种动力总成、双电机动力总成及电动车辆。动力总成的壳体包括电机槽、减速器槽和电控槽,电机槽容纳电机的定子和转子,减速器槽容纳减速器的齿轮组和传输件,电控槽容纳控制器的电气组件。电气组件通过传输件向定子的绕组输出三相电流。电机通过减速器传动连接车轮。沿电机轴向电机槽和电控槽排列于减速器槽的同一侧。壳体的一个连通孔用于连通减速器槽和电控槽,壳体放入另一个连通孔用于连通减速器槽和电机槽。传输件包括两个穿缸件和铜排,一个穿缸件用于穿过一个连通孔和用于电连接铜排的一端和电气组件。另一个穿缸件用于穿过另一个连通孔和用于电连接铜排的另一端和定子的绕组。有利于动力总成的小型化,节省电动车辆的空间。
