Patent ID: 7766777

Claim:
Rotational speed superposition device comprising: an input shaft ( 1 ) and an output shaft ( 2 ) disposed in the longitudinal direction with respect to one another, a carrier system ( 11 a , 11 b ) fixed to the vehicle body, in which the input shaft ( 1 ) and the output shaft ( 2 ) are rotatably positioned such that they are at least partially bearing supported, an auxiliary drive ( 6 , 7 ) with a stator ( 7 ) disposed on the carrier system ( 11 a , 11 b ) and with a rotatably supported rotor ( 6 ) disposed axially parallel with respect to the input shaft ( 1 ), characterized in that the input shaft ( 1 ) is connected torsion-tight with a first toothed disk ( 3 ) and that the output shaft ( 2 ) is connected torsion-tight with a second toothed disk ( 4 ), and that on the rotor ( 6 ) at least one further toothed wheel ( 5 ) is disposed spaced apart from the rotational axis of the rotor ( 6 ) and rotatable about the input shaft ( 1 ) pivotable about its own axis, the toothing ( 18 ) of the further toothed wheel ( 5 ) engaging the two toothings ( 16 , 17 ) of the first and of the second toothed disk ( 3 , 4 ).
