The invention relates to a double-motor electric drive axle assembly which comprises an axle housing, a gearbox housing assembly and a fixing piece. The axle housing is provided with a through installation channel, the installation channel is perpendicular to the axial direction of the axle housing, and the two end faces of the installation channel are provided with a first end face and a second end face which are arranged in parallel. The gearbox shell assembly comprises a first shell part, a second shell part and an end cover. The first shell part and the second shell part are oppositely arranged, abut against each other and are arranged in the mounting channel in a penetrating manner after being connected; the side, facing the first end face, of the first shell part is provided with a first sealing face, the first sealing face abuts against and is matched with the first end face, the second shell part is provided with a second sealing face in the same direction as the second end face, the second sealing face and the second end face are coplanar, and the end cover covers the second sealing face and the second end face and is fixedly connected through a fixing piece. Compared with the prior art, the shell strength, the sealing performance and the size precision can be considered at the same time, and the problem that double sealing faces cannot guarantee the positioning precision at the same time is solved.

    本发明涉及一种双电机电驱桥总成,包括桥壳、变速箱壳体总成及固定件;桥壳设有贯通的安装通道,安装通道垂直于桥壳的轴向,安装通道的两端面设有第一端面及第二端面,二者平行设置;变速箱壳体总成包括第一壳体部、第二壳体部及端盖;第一壳体部与第二壳体部相对设置并抵接固定,二者连接后穿设于安装通道中;第一壳体部朝向第一端面的一侧设有第一密封面,第一密封面与第一端面相抵接匹配,第二壳体部设有与第二端面同向的第二密封面,第二密封面与第二端面相共面,端盖覆盖于第二密封面与第二端面,并通过固定件连接固定。与现有技术相比,本发明可同时兼顾壳体强度、密封性能和尺寸精度,解决了双密封面无法同时保证定位精度的问题。
