Abstract:
1. A drive assembly for use in the axle drive of a motor vehicle between an axle differential and a sideshaft, comprising: an intermediate shaft supported so as to be rotatable around an axis of rotation (A), said intermedial shaft having a first end connected to an output gear of the axle differential in a rotationally fixed way and a second end connected at least indirectly to the sideshaft in a rotationally fixed way; a controllable coupling unit arranged coaxially relative to said intermediate shaft and comprising a coupling cage with outer plates and a coupling hub with inner plates, said coupling cage connected in a rotationally fixed way to a differential carrier of the axle differential, said coupling cage rotatably supported around said axis of rotation (A) relative to a bearing support, said coupling hub connected in a rotationally fixed way to said intermediate shaft, wherein said outer plates and said inner plates are arranged so as to axially alternate and jointly form a plate package; and wherein said coupling cage extends in the axial direction from said differential carrier to said bearing support; wherein at its end facing the axle differential, said coupling cage sealed by means of a first rotary seal relative to a housing of the axle differential and, at its end facing said bearing support, said coupling cage is sealed by means of a second rotary seal relative to said bearing support, wherein said coupling cage forms a closed housing.
