ABSTRACT:
A drive assembly (1) includes a differential (3) with a differential carrier (7) and two output shafts (19) connected to the differential carrier (7) via a differential gear set (10). The assembly includes at least one transmission stage (25) with a first sun gear (26) connected to the differential carrier (7), and a second sun gear (28) connected to one of the two output shafts (19), and at least one parallel planetary gear (27) which engages the sun gears (26, 28) and which is rotatably held in a carrier element (32) which can be coupled to a stationary housing (18). The two sun gears have profile-displaced teeth with different numbers of teeth and are arranged at the same axial distance (C) from the at least one planetary gear (27). The planetary gear (27) has two toothed portions (29, 30) with corresponding teeth.
