Abstract
A dual clutch device having an input side, a first output side, and a second output side, which are arranged rotatably about an axis of rotation, and having a first, radially outer friction clutch for producing frictional engagement between the input side and the first output side and a second, radially inner friction clutch for producing frictional engagement between the input side and the second output side. Each friction clutch has a first friction element, which engages in the input side in a torque-transmitting manner, a second friction element, which engages in the associated output side in a torque-transmitting manner, a control element for providing an axially pressing force on the friction elements, and a leaf spring element, which is spirally wound around the axis of rotation and which is arranged axially between the control element and the friction elements.
