Abstract:
A torque transfer device comprising:a first clutch device actuated by a first hydraulic slave cylinder/piston device with a first slave piston; a second clutch device actuated by a second hydraulic slave cylinder/piston device with a second slave piston; a hydraulic master cylinder/piston device with a master piston, and with an output port branching into a first conduit leading to the first hydraulic slave cylinder/piston device and a second conduit leading to the second hydraulic slave cylinder/piston device; an electrical motor arranged to drive the hydraulic master cylinder/piston device; a first valve device arranged in the first conduit to control a hydraulic pressure supplied to the first hydraulic slave cylinder/piston device; and a second valve device arranged in the second conduit to control a hydraulic pressure supplied to the second hydraulic slave cylinder/piston device; wherein the first valve device and the second valve device are controlled electromagnetically, independent of each other, so that actuation of the first clutch device by the first hydraulic slave cylinder/piston device and actuation of the second clutch device by the second hydraulic slave cylinder/piston device are controlled independently of each other.
