The embodiment of the invention provides a dual-motor power assembly and an electric vehicle, a main shell of the dual-motor power assembly comprises a middle shell, two speed reducers are arranged on the two sides of the middle shell in the axial direction of the dual-motor power assembly, and the middle shell comprises two side faces and a peripheral face. The two side faces respectively comprise two speed reducer containing grooves, and groove openings of the two speed reducer containing grooves are opposite in the axial direction of the dual-motor power assembly. The peripheral surface comprises the accommodating groove, and the concave direction of the accommodating groove faces the gap between the two speed reducers, so that the intermediate shell can fully utilize the gap between the two speed reducers to form the accommodating groove, and the space in the accommodating groove is used for accommodating part of electrical components, so that the space for arranging the electrical components outside the total shell can be saved; the overall size of the dual-motor power assembly can be reduced, and therefore the layout of the dual-motor power assembly in a whole vehicle can be optimized.
本申请实施例提供一种双电机动力总成及电动车,双电机动力总成的总壳体包括一个中间壳体,沿双电机动力总成的轴向两个减速器排列于中间壳体的两侧,中间壳体包括两个侧面和一个外周面。其中,两个侧面分别包括两个减速器容纳槽,两个减速器容纳槽的槽口沿双电机动力总成的轴向相背。外周面包括容纳槽,容纳槽的凹陷方向朝向两个减速器之间的间隙,使得中间壳体可以充分利用两个减速器之间的间隙形成容纳槽,容纳槽内的空间用来容纳部分电气部件,从而可以节省总壳体外部布置电气部件的空间,有利于缩小双电机动力总成的整体体积,从而有利于优化双电机动力总成在整车内的布局。
