Cast steel car axle housing body end structure

The utility model discloses a cast steel car axle housing body end structure, it includes that it personally experiences sth. Part of the body and establish the end flange at axle housing body both ends to cast fashioned axle housing by cast steel, the diaxon of end flange is the perpendicular to the terminal surface, the end flange is equipped with a plurality of strengthening ribs along circumferencial direction evenly distributed between the axial terminal surface in the middle part of the axle housing body and the axle housing body. The utility model discloses an above technical scheme, the diaxon of end flange is the perpendicular to the terminal surface, processing end flange bolt hole in -process, can not produce disconnected screw tap and drill bit, directly improves this process production efficiency, avoids the abrupt change of cross -section simultaneously to reduce the production of thermal center. Simultaneously the strengthening rib sets up the intensity that can improve end flange and axle housing body coupling department.
