A drive train unit for a hybrid vehicle includes an input shaft arranged for rotationally fixed attachment to an output of a transmission, an output shaft, an electric machine with a rotor, a clutch, and an actuating unit operatively connected to the clutch. The actuating unit has an actuator and an actuating bearing, displaceable by the actuator. The clutch may be a separating clutch operatively inserted between the rotor and the input shaft, or a friction clutch operatively inserted between the input shaft and the output shaft. The clutch may be a self-intensifying clutch with a leaf spring adjusted at a set angle relative to a reference plane oriented perpendicular to an axis of rotation such that, in a driving direction of a first clutch component, a first friction element is applied to a second friction element with an additional axial force.

Drive train unit for a hybrid vehicle, transmission unit and drive train

A device for actuating a friction clutch with automatic adjustment. An actuating movement for engaging and disengaging the clutch is transmitted to a pressing component. The adjusting device includes a sensing component that is biased in the direction of an adjusting movement and compensates for sensing play that occurs as a result of wear when the clutch is engaged, and that compensates for play that occurs when the clutch is disengaged after compensation of the sensing play in the movement transmission between the actuating component and the transmission component. When the clutch is engaged and wear is present, the sensing component moves out of contact against a spring component which, when the clutch is engaged and wear is present, comes into contact against a stop before the fully engaged state of the clutch is reached.
