Abstract
A torque-distribution device includes a rotor carrier couplable to an input shaft, a clutch device having a disc pack, and an actuation device for actuating the clutch device. The actuation device includes a primary piston, and a secondary piston. The primary piston delimits a primary pressure chamber and is movable against the disc pack when pressure is applied to the primary pressure chamber. The secondary piston delimits a secondary pressure chamber and is movable to move the primary piston against the disc pack when pressure is applied to the secondary pressure chamber. Pressure medium arranged in the primary pressure chamber is supplied by a first feed line and pressure medium arranged in the secondary pressure chamber is supplied by a second feed line, independent of the first feed line, such that pressure can be applied to the primary piston and to the secondary piston independently.
