The invention discloses a shell of a semi-coaxial electric drive axle assembly. The left shell end wall of the shell is provided with a lower wall part corresponding to a lower cavity and an upper wall part corresponding to an upper cavity. The lower wall part protrudes rightwards relative to the upper wall part, so that a blocking wall is formed on the boundary line of the lower wall part and the upper wall part. Or, the lower wall part is flush with the upper wall part or protrudes leftwards relative to the upper wall part, a baffle is arranged on the boundary line of the upper wall part and the lower wall part, and a partition plate is arranged on the right side of the lower wall part and seals the cavity opening of the lower cavity. The volume of the lower cavity of the left shell is very small or even zero, so that the lubricating performance of the electric drive axle assembly can be improved, the semi-annular wall, used for supporting the left bearing of the differential mechanism, of the left shell can be supported by the lower wall part protruding rightwards or the partition plate, the strength is high, and the oil stirring loss of the left shell is small.

    本发明公开了一种半同轴式电驱桥总成的壳体,该壳体的左壳端壁具有对应下腔的下壁部和对应上腔的上壁部。下壁部相对上壁部向右凸起,使下壁部在与上壁部的交界线上形成挡壁。或者,下壁部与上壁部平齐或相对上壁部向左凸起,在上壁部与下壁部交界线上设置挡板,在下壁部的右侧设置隔板,隔板封闭下腔的腔口。该左壳的下腔容积很小甚至为零,这样能够提升电驱桥总成的润滑性能,而且,该左壳的用于支撑差速器左轴承的半环形壁能够被向右凸起的下壁部或者隔板支撑,因而强度较高,而且,该左壳的搅油损失小。
