The invention provides an axial double-motor double-clutch double-speed-ratio electric vehicle power assembly and an electric vehicle, which comprises a main shell, a composite motor and a double-clutch transmission. The composite motor comprises a first motor and a second motor which are sequentially arranged in the main shell in the axial direction, and the first motor comprises a first rotor, a first stator and a first motor shaft; the first stator is arranged at one end in the main shell, the first rotor is rotatably arranged in the first stator, the first motor shaft is sleeved with the first rotor, and the first end of the first motor shaft penetrates through the main shell; the second motor comprises a second rotor, a second stator and a second motor shaft. By adopting the configuration of combining the axial composite motor and the double-speed-ratio transmission, the double-motor power can be reasonably distributed to meet different working conditions and speed requirements per hour, the device is suitable for longitudinal installation, the structure is compact, multiple functions are achieved, multi-motor power driving can be achieved through the configuration of a front power assembly and a rear power assembly, and the endurance mileage is increased; and the configuration cost and the operation cost of the whole vehicle are reduced.

    本发明提供一种轴向双电机双离合双速比电动车动力总成及电动汽车,包括主壳体、复合电机和双离合变速器,复合电机包括依次沿轴向设置于主壳体内部的第一电机和第二电机,第一电机包括第一转子、第一定子和第一电机轴,第一定子设置于主壳体内部的一端,第一转子可转动地设置于第一定子内,第一电机轴套设于第一转子内,第一电机轴的第一端贯穿主壳体;第二电机包括第二转子、第二定子和第二电机轴。通过采用轴向复合电机与双速比传动结合的配置,可以合理地分配双电机动力以应对不同工况及时速要求,适用于纵置安装,结构紧凑功能多,可以前后两副动力总成配置实现多电机动力驱动,增加续航里程,降低整车的配置成本和运行成本。
