Abstract: An electrified drive train for a motor vehicle, having a heat generator, includes at least one electrical drive machine, and a heat dissipation circuit which has at least one first heat exchanger and one second heat exchanger for dissipating heat from a cooling circuit which is routed through the heat generator. During operation, a fluid used in the heat dissipation circuit flows through the first heat exchanger and, parallel thereto, through the second heat exchanger.

Abstract: An electrified drive train for a motor vehicle has a heat generator, which includes at least one electric drive machine; and a cooling circuit, which is led through the electric drive machine and has a heat exchanger for removing heat from the cooling circuit. With respect to the direction of flow of the fluid used in the cooling circuit, the heat exchanger is arranged in the cooling circuit downstream of the heat generator to be cooled.

Abstract: A hybridised powertrain unit (1) for a motor vehicle is provided, with a first part-unit (3) having an electrical machine (2) and with a second part-unit (6) having an internal combustion engine (4) and a powershift transmission (5) connected downstream of the internal combustion engine (4), wherein the two part-units (3, 6) are coupled on the output side to an output drive (10) via a joint planetary gearbox (7), the ring gear (8) of which is connected to a transmission output (9) of the powershift transmission (5). A method for operating this powertrain unit (1) is also provided.

Abstract: 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.

Abstract: A clutch unit which has a friction clutch, that includes a pressure plate, which is rotationally fixed to the housing, yet displaceable to a limited extent in the axial direction. The housing can be connected to a counter-pressure disk, and lever elements which are positioned in an annular arrangement and which are disposed between the housing and the pressure plate. The elements are supported on a rolling support carried by the housing and to which pressure can be applied at the radially inner lever tips thereof in order to close the friction clutch.

Abstract: 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.
