The invention discloses an automobile and a double-motor electric drive assembly thereof. The double-motor electric drive assembly comprises a first drive mechanism and a second drive mechanism which are located on the same drive axle. The first driving mechanism comprises a first motor, a first parallel shaft gear mechanism and a first half shaft which are connected in sequence; the second driving mechanism comprises a second motor, a second parallel shaft gear mechanism and a second half shaft which are connected in sequence; the first driving mechanism and the second driving mechanism are different in structure so as to avoid overlapping of resonance frequencies of the first driving mechanism and the second driving mechanism. The double-motor electric drive assembly is low in noise during operation.

    一种汽车及其双电机电驱总成,该双电机电驱总包括:位于同一个驱动桥上的第一驱动机构和第二驱动机构;所述第一驱动机构包括依次连接的第一电机、第一平行轴齿轮机构和第一半轴;所述第二驱动机构包括依次连接的第二电机、第二平行轴齿轮机构和第二半轴;其中,所述第一驱动机构和所述第二驱动机构的结构不同以避免第一驱动机构和第二驱动机构的共振频率重叠。该双电机电驱总成运行时噪音小。
