The invention relates to the technical field of vehicles, and provides a transmission assembly, a multi-gear integrated electric drive axle assembly and a vehicle. The transmission assembly comprises a first-stage transmission shaft, a second-stage transmission shaft and a third-stage transmission shaft which are arranged in parallel; the first-stage transmission shaft is suitable for being coaxially connected with an output shaft of a motor. The secondary transmission shaft is in transmission connection with the primary transmission shaft through a transmission mechanism; a gear shifting mechanism is arranged between the second-stage transmission shaft and the third-stage transmission shaft and comprises at least two gears capable of being switched, and the second-stage transmission shaft and the third-stage transmission shaft are combined at different transmission ratios under different gears. The third-stage transmission shaft and the first-stage transmission shaft are coaxially arranged and are used for providing power output; in this way, the third-stage transmission shaft and the first-stage transmission shaft are coaxially arranged, the radial space occupation of each stage of transmission shaft can be reduced, the gravity center of the electric drive axle is closer to the center of the axle, the gravity center suspension distance is greatly shortened, and the stability and reliability of the whole structure are improved.

    本发明涉及车辆的技术领域,提供一种变速器总成、多挡集成电驱桥总成及车辆,变速器总成包括:平行布置的一级传动轴、二级传动轴和三级传动轴;一级传动轴适用于同轴连接电机的输出轴;二级传动轴与一级传动轴通过传动机构传动连接;二级传动轴与三级传动轴之间设置有换挡机构,换挡机构包括能够切换的至少两个挡位,不同挡位下二级传动轴和三级传动轴以不同的传动比结合;三级传动轴与一级传动轴同轴设置,用于提供动力输出;如此设置,三级传动轴与一级传动轴同轴设置,能够减小各级传动轴的径向空间占用,使得电驱桥的重心更靠近桥中心,极大的缩小了重心悬置距离,提高了整体结构的稳定性和可靠性。
