Patent ID: 8517883

Claim:
A transmission module for a variable distribution of torque in the driveline of a motor vehicle, comprising: a driveshaft ( 3 ) which, relative to a housing ( 8 ), is rotatingly drivable around a first axis of rotation (A), a hollow shaft ( 4 ) which is arranged coaxially relative to the driveshaft ( 3 ) and which is rotatingly drivable relative thereto, a transmission stage ( 5 ) having a first sun gear ( 32 ) which can be drivingly connected to the hollow shaft ( 4 ), a second sun gear ( 34 ) which is arranged so as to coaxially adjoin the first sun gear ( 32 ) and which is connected to the driveshaft ( 3 ) in a rotationally fixed way, and a hollow gear ( 33 ) which, in the housing ( 8 ), is rotatably supported on a second axis of rotation (B) extending parallel to the first axis of rotation (A), wherein said hollow gear ( 33 ) comprises a first internal toothing which meshingly engages the first sun gear ( 32 ) and wherein said hollow gear ( 33 ) comprises a second internal toothing which meshingly engages the second sun gear ( 34 ), wherein the first and the second sun gear ( 32 , 34 ) comprise different numbers of teeth; a friction coupling ( 6 ) having a first coupling part ( 26 ) which is connected to the first sun gear ( 32 ) in a rotationally fixed way and having a second coupling part ( 27 ) which is rotatable relative to the first coupling part ( 26 ) and which is connected to the hollow shaft ( 4 ) in a rotationally fixed way, wherein, by actuating the friction coupling ( 6 ), the first sun gear ( 32 ) is drivingly connected to the hollow shaft ( 4 ).
