The invention discloses an automobile and a single-axle double-motor electric drive assembly thereof. The single-axle double-motor electric drive assembly comprises a first drive mechanism and a second drive mechanism, the first driving mechanism comprises a first motor, a first planetary gear mechanism and a first half shaft which are in transmission connection in sequence; the second driving mechanism comprises a second motor, a second planetary gear mechanism and a second half shaft which are in transmission connection in sequence; wherein the first planetary gear mechanism and/or the second planetary gear mechanism are/is a multi-stage NGW planetary gear reducer. The first planetary gear mechanism and the second planetary gear mechanism in the single-axle double-motor electric drive assembly are multi-stage NGW planetary gear reducers, and compared with an NW planetary gear reducer adopted in an existing double-motor electric drive assembly technology, the axial size of the single-axle double-motor electric drive assembly is smaller, the occupied axial space is smaller, and the service life of the single-axle double-motor electric drive assembly is prolonged. And the problem that tooth alignment is difficult to assemble does not exist.
一种汽车及其单桥双电机电驱总成,该单桥双电机电驱总成包括: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传动连接的第一电机、第一行星齿轮机构和第一半轴;所述第二驱动机构包括依次传动连接的第二电机、第二行星齿轮机构和第二半轴;其中,所述第一行星齿轮机构和/或所述第二行星齿轮机构为多级NGW行星齿轮减速器。本申请中的单桥双电机电驱总成中的第一行星齿轮机构和第二行星齿轮机构为多级NGW行星齿轮减速器,相较于现有的双电机电驱总成技术中所采用的NW行星齿轮减速器,其轴向尺寸更小,需要占用的轴向空间更少,且不存在装配对齿困难的问题。
