The invention relates to the technical field of automobile power, in particular to a four-gear electric drive axle assembly and a vehicle. The four-gear electric drive axle assembly comprises a motor, a first shaft set, a second shaft set, a third shaft set and a differential mechanism, a first gear shifting mechanism can be selectively connected with a planet carrier or a sun gear so that the first gear shifting mechanism can have two gear states, and a second gear shifting mechanism can be selectively in transmission connection with any one of two driving gears so that the gear shifting mechanism can have two gear states. The first gear shifting mechanism and the second gear shifting mechanism are mutually matched to enable the second gear shifting mechanism to be in two gear states, so that the four-gear electric drive axle assembly has four gears, and compared with a parallel shaft gear train or a planetary gear train for achieving the four gears, the four-gear electric drive axle assembly is small in longitudinal space occupation, high in transmission efficiency and capable of achieving the four gears. And the structure is more compact.

    本发明涉及汽车动力技术领域,尤其涉及一种四档电驱桥总成及车辆。四档电驱桥总成包括电机、第一轴组、第二轴组、第三轴组和差速器,由于第一换挡机构能够选择性的与行星架或太阳轮连接,以使第一换挡机构具有两种档位状态,而第二换挡机构能够选择性地与两个主动齿轮中的任一个传动连接,以用于使第二换挡机构可处于两种档位状态,这样,第一换挡机构与第二换挡机构二者相互配合,可以使四档电驱桥总成具有四档位,相较于实现四档的平行轴轮系或者行星轮系,本申请提供的四档电驱桥总成纵向空间占用少,传动效率高,结构更为紧凑。
