The invention relates to a non-closed split type rigid drive axle housing assembly which comprises a first drive axle housing, a first speed reducer housing, a second speed reducer housing, a second drive axle housing and a sealing sleeve assembly. The first drive axle housing, the first speed reducer housing, the second speed reducer housing and the second drive axle housing are in plane fit; the outer sides of the first drive axle housing and the first speed reducer housing and the outer sides of the second drive axle housing and the second speed reducer housing are in non-closed connection, and the inner sides of the first drive axle housing and the first speed reducer housing and the second drive axle housing and the second speed reducer housing are connected through the sealing sleeve assemblies. Internal static sealing of the drive axle housing is realized; the connecting structure is simple, few in machining part and easy to machine, and the die and machining cost is effectively reduced; the connecting mode of the axle housing assembly optimizes the stress of the speed reducer housing and reduces the strength requirement of the speed reducer housing; according to the axle housing assembly structure, the space under the spring is saved, the arrangement of the whole vehicle is facilitated, and light weight is realized.

    本发明涉及一种非封闭分体式刚性驱动桥桥壳总成,第一驱动桥桥壳、第一减速器壳、第二减速器壳、第二驱动桥桥壳、密封套总成;所述第一驱动桥桥壳、第一减速器壳、第二减速器壳与第二驱动桥桥壳之间为平面贴合;所述第一驱动桥桥壳与第一减速器壳、第二驱动桥桥壳与第二减速器壳之间外侧为非封闭连接,内侧采用所述密封套总成连接所述第一驱动桥桥壳与所述第一减速器壳、所述第二驱动桥桥壳与所述第二减速器壳,实现驱动桥壳内部静密封;本发明连接结构简单,加工部位少且易加工,有效降低模具及加工成本;所述桥壳总成连接方式优化了减速器壳体受力,降低减速器壳体强度要求;所述桥壳总成结构利于节省簧下空间,方便整车布置,实现轻量化。
