Mounting of a differential housing of a differential gear in an axle gear unit housing of a motor vehicle

摘要

In a bearing arrangement of a differential casing of a differential transmission in an axle transmission light metal casing of a motor vehicle, a bearing intermediate sleeve is inserted in a bearing eye of the axle transmission casing so that it cannot move. An axle journal of the differential casing is supported by a conical roller bearing on the bearing intermediate sleeve and one shaft end of a driven shaft of the differential gear is supported by a shaft bearing in the bearing intermediate sleeve. In order to achieve a compact and light structure despite high bearing forces, provision is made for the axle transmission casing to consist of aluminum and to be formed integrally with the bearing eye. The bearing intermediate sleeve also consists of aluminum and a rolling contact bearing is used for the associated shaft bearing.
