Abstract
A torque distribution device includes a rotor support, an internal disc carrier, a clutch device including a disc pack and an actuation device for actuating the clutch device. The actuation device includes a stationary holding element, a spring element, and primary and secondary pistons axially displaceably mounted on the holding element. The primary piston delimits a primary pressure chamber and is arranged to be moved in a first axial direction against the disc pack the primary pressure chamber is pressurized. The secondary piston delimits a secondary pressure chamber and is movable counter to a restoring force of the spring element in a direction opposite the first axial direction the secondary pressure chamber is pressurized. The spring element is coupled to the primary piston to move the primary piston in the direction opposite the first axial direction when the secondary pressure chamber is depressurized.
