The invention discloses an electric drive axle housing assembly. In the electric drive axle housing assembly, an axle housing cover comprises a cavity, a first protrusion and a second protrusion which extend out of the cavity are sequentially arranged in the cavity in the first direction, and a first side wall face on the first protrusion and a second side wall face on the second protrusion are oppositely arranged in the first direction. And a mounting cavity for accommodating the output gear is defined by the wall surface between the first bulge and the second bulge in the cavity. The oil suction part comprises an oil channel located in the first protrusion and an oil pump, an oil suction opening of the oil channel is formed in the first bottom wall face of the first protrusion, an oil outlet of the oil channel is communicated with the oil pump, the oil suction opening is independent of the installation cavity, and the oil suction opening is communicated with the installation cavity. According to the electric drive axle housing assembly, on the basis that the liquid level needed by lubrication is guaranteed, the oil adding amount of the middle cavity is reduced, lubricating oil is saved, the space in the middle cavity is fully utilized, the compactness of the structure is improved, the stirred lubricating oil is prevented from directly entering the oil suction opening, and normal operation of an oil pump is guaranteed.

    本申请公开了一种电驱桥壳总成。电驱桥壳总成中,桥壳盖包括腔体,腔体内沿第一方向依次设有向腔体外延伸的第一凸起和第二凸起,第一凸起上的第一侧壁面和第二凸起上的第二侧壁面沿第一方向相对设置,与腔体内位于第一凸起和第二凸起之间的壁面共同限定出用于容纳输出齿轮的安装腔。吸油部包括位于第一凸起内的油道和油泵,油道的吸油口设于第一凸起的第一底壁面,油道的出油口与油泵相连通,吸油口独立于安装腔,吸油口与安装腔相连通。本申请提供的电驱桥壳总成,在保证润滑所需的液位基础上,减少了中部腔体的加油量,节约了润滑油,并充分利用中部腔体内部的空间,增加了结构的紧凑性,避免搅动后的润滑油直接进入吸油口,保证油泵正常运行。
