Abstract:
1. A drive assembly for variable torque distribution in a driveline of a motor vehicle, comprising: a differential with a differential carrier and two output shafts which are drivingly connected to the differential carrier via a differential gear set and which, relative to one another, have a compensating effect; at least one transmission stage with a first sun gear drivingly connected to the differential carrier, a second sun gear which is arranged to coaxially adjoin the first sun gear and which is drivingly connected to one of the two output shafts, and at least one parallel planetary gear whose teeth engage teeth of the first sun gear and the second sun gear and which is rotatably held in a carrier element rotating around an axis of rotation (B), wherein the carrier element can be coupled to a stationary housing; wherein the first sun gear and the second sun gear, relative to one another, comprise profile-displaced teeth with different numbers of teeth and are arranged at the same axial distance (C) from the at least one planetary gear; wherein the planetary gear comprises two toothed portions whose teeth correspond to one another.
