The invention provides a dual-motor power assembly and an electric vehicle, a shell of the dual-motor power assembly comprises a middle partition plate, the middle partition plate divides the shell into two containing cavities, each containing cavity is used for containing a motor and a speed reducer, the middle partition plate is used for fixing a conductive piece and two bearings, and the middle partition plate comprises two bearing grooves and a through hole. The through hole penetrates through the groove bottoms of the two bearing grooves in the axial direction of the double-motor power assembly, the conductive part penetrates through the through hole in the axial direction of the double-motor power assembly, the two conductive ends of the conductive part are arranged on the two sides of the middle partition plate, and each conductive end is used for being electrically connected with one motor shaft. The through hole is formed in the middle partition plate, the conductive part penetrates through the through hole, and the two conductive ends are electrically connected with the motor shafts in the two containing cavities, so that current of the bearings and the motor shafts is conducted to the middle partition plate, bearing shell connection is achieved, bearing electrocorrosion is reduced, grounding of the two motors is achieved through one conductive part penetrating through the through hole, the number of parts is small, and cost is low. Assembly is simple, and installation is fast.
本申请提供一种双电机动力总成及电动车,双电机动力总成的壳体包括一个中隔板,中隔板将壳体分隔成两个容纳腔,每个容纳腔用于容纳电机及减速器,中隔板用于固定一个导电件和两个轴承,中隔板包括两个轴承槽和一个通孔。通孔沿双电机动力总成轴向贯穿两个轴承槽的槽底,沿双电机动力总成轴向,导电件穿过通孔,导电件的两个导电端排列于中隔板的两侧,每个导电端用于电连接一个电机轴。通过在中隔板开设通孔,使导电件贯穿通孔布置,使得两个导电端与两个容纳腔内的电机轴电连接,从而将轴承、电机轴的电流传导至中隔板,实现轴承接壳,减少轴承电腐蚀,通过一个导电件穿过通孔实现两个电机的接地,零件少,装配简单、安装快速。
