Abstract
A drive module (5, 6) for a variable torque distribution in the driveline of a motor vehicle. The drive module (5, 6) has a first shaft (19) rotatably supported relative to a stationary housing (18); a second shaft (22) which is drivingly connected to the first shaft (19); and a transmission stage (25) arranged in the torque flow between the first and second shafts (19, 22). The transmission stage (25) has at least one planetary gear (27) and a rotating carrier element (32). A coupling (37) serves to couple the carrier element (32) relative to the housing (18). When coupled, torque transmission occurs from one of the first or second shaft (19, 22), to the other one of the two shafts. The housing (18), the first shaft (19), the second shaft (22), the transmission stage (25) and the coupling (37) form part of a unit adapted to attach to a drive (3).
