The invention discloses a vehicle drive axle assembly, and belongs to the technical field of vehicles. The vehicle drive axle assembly comprises a speed reducer shell, a bearing seat, a driving bevel gear, a first bearing and a second bearing, wherein the bearing seat is positioned in the speed reducer shell and is fixedly connected with the speed reducer shell, the driving bevel gear comprises a first bevel gear, a first shaft journal and a second shaft journal, the first shaft journal is connected to one side of the first bevel gear, the second shaft journal is connected to the other side of the first bevel gear, the first bearing is arranged on the first shaft journal in a sleeving mode and installed in the speed reducer shell, the inner surface of the first bearing is attached to the first shaft journal, the outer surface of the first bearing is attached to the speed reducer shell, the second bearing is arranged on the second shaft journal in a sleeving mode and installed in the bearing seat, and the inner surface of the second bearing is attached to the second shaft journal. According to the vehicle drive axle assembly, the space occupied by the assembled driving bevel gear, the first bearing and the second bearing in the axial direction of the first shaft journal is reduced, the compactness of the vehicle drive axle is facilitated, and then the vehicle axial arrangement space occupied by the vehicle drive axle assembly is reduced.

    本发明公开了一种车辆驱动桥总成,其属于车辆技术领域,包括减速器壳;轴承座,位于减速器壳内,并与减速器壳固定连接;主动锥齿轮,包括第一锥齿轮、第一轴径及第二轴径,第一轴径连接于第一锥齿轮的一侧,第二轴径连接于第一锥齿轮的另一侧;第一轴承,套设于第一轴径并安装在减速器壳内,且第一轴承的内表面与第一轴径贴合,第一轴承的外表面与减速器壳贴合;第二轴承,套设于第二轴径并安装于轴承座中,且第二轴承的内表面与第二轴径贴合。本发明提供的车辆驱动桥总成减小了装配后的主动锥齿轮、第一轴承及第二轴承在第一轴径轴向上占据的空间,有利于车辆驱动桥的紧凑性,进而减小了车辆驱动桥总成占据的车辆轴向布置空间。
