The invention relates to the field of heavy truck electric drive axles, in particular to a heavy truck electric drive axle housing and transmission system.The heavy truck electric drive axle housing comprises an axle housing body, the axle housing body comprises an axle package and axle tubes arranged on the two sides of the axle package, half shafts are installed in the axle tubes, the axle tubes are communicated with an inner cavity of the axle package, and the axle tubes are arranged in the axle package. One port, close to the axle package, of the axle tube is a lubricating oil port; lubricating oil throttling plates are arranged at the positions, corresponding to the lubricating oil ports in the left side and the right side, of an inner cavity of the axle package respectively, and the lubricating oil throttling plates block the middles of the lubricating oil ports to divide the lubricating oil ports into upper end oil ports and lower end oil ports. When a vehicle inclines, the flowing speed of lubricating oil can be automatically adjusted, it is guaranteed that a bearing in the speed reducer can be fully lubricated even under the extreme condition, and faults caused by poor lubrication are avoided.

    本发明涉及重卡电驱桥领域,具体而言,涉及一种重卡电驱桥桥壳及传动系统,包括桥壳本体,所述桥壳本体包括桥包及设置于所述桥包两侧的轴管,所述轴管内安装半轴,所述轴管与所述桥包的内腔连通,且所述轴管上靠近于所述桥包的一端口为润滑油口;所述桥包的内腔且对应于左右两侧的所述润滑油口处分别设置有润滑油节流板,所述润滑油节流板封堵于所述润滑油口的中部而将所述润滑油口分割为上端油口和下端油口。当车辆倾斜时,能够自动调节润滑油的流动速度,确保即使在极端情况下,减速器内的轴承也能获得充足润滑,避免因润滑不良而导致的故障。
