A decoupling clutch for a hybrid module of a motor vehicle is disclosed. The decoupling clutch includes an intermediate shaft which is drivable by a crankshaft. A clutch disk is connected non-rotatingly to the intermediate shaft. A counter-pressure plate is connected to a transmission input shaft. The counter-pressure plate is connected non-rotatingly to the clutch disk at least when the decoupling clutch is in the engaged position. A first roller bearing radially supports the intermediate shaft. A carrier element radially supports a rotor of an electric motor. The first roller bearing is nested radially between a supporting section of the carrier element and an external circumferential surface of the intermediate shaft.

A torque transmission device for the drive train of a passenger car. The drive train includes two engines, wherein one of said engines is an electromechanical energy converter. The torque transmission device is inserted into a rotor recess, which is arranged in a rotor assembly of the electromechanical energy converter.

Torque transmission device

A hybrid drivetrain and method for controlling a friction clutch of a hybrid drivetrain of a motor vehicle having a combustion engine which is coupled by means of a freewheel to a transmission input shaft of a transmission to transmit the engine torque, and having an electric machine which starts the combustion engine and/or propels the motor vehicle, which friction clutch transmits to the combustion engine a summed torque formed of a starting torque for starting the combustion engine by means of the electric machine and a drag torque which acts on the combustion engine when the drivetrain is in drag mode. To be able to operate the friction clutch reliably and to avoid over-dimensioning of the friction clutch as a result of high summed torques, a torque present at the friction clutch is limited to a predefined transmission torque which can be transmitted via the friction clutch.

A hybrid module for a drive train of a vehicle having an internal combustion engine and a transmission. The hybrid module operates between the internal combustion engine and the transmission and has an electric drive, a clutch, and a freewheel, and the clutch and the freewheel are provided parallel to each other in order to transmit torque from the internal combustion engine toward the transmission, the freewheel transmits torque coming from the internal combustion engine to the transmission and opens for torque directed in the opposite direction, and a portion of the torque produced by the internal combustion transmitted by the freewheel can be set by setting a torque that can be transmitted by the clutch so that the vehicle can be driven by the internal combustion engine or the electric drive or both at the same time.

A wrap-around braking device for a planetary gear train, having at least one wrap-around element, with first and second cam devices, and is designed to wrap around at least one ring gear of the planetary gear train for braking engagement. A shift fork, which can be moved in the axial direction of the shift fork and which has first and second actuating elements that act oppositely in the axial direction and which is mounted in a rotationally fixed manner in a housing that has at least first and second stops in the axial direction. For braking engagement on the ring gear, which rotates in a first rotational direction, the shift fork can be moved in a first axial direction such that the first actuating element interacts with the first cam device, while the second stop opposite the first actuating element in the axial direction interacts with the second cam device.

A torque transmission unit which has a first centrifugal mass that can be non-rotatably associated with an internal combustion engine and a second centrifugal mass that is connected downstream of the first mass and can be associated with a transmission. The second centrifugal mass has a rotor of an electric machine for transmitting a torque that can be electrically generated to the second centrifugal mass and a centrifugal force pendulum for reducing torsional vibrations.

The crankshaft of a piston engine is assembled with a vibration damper into a discrete module prior to mounting of such module in axial and/or radial bearings of the housing of the engine. The damper has an input element which rotates with the camshaft and a mass which is angularly movable relative to the input element against the resistance of coil springs. The input element can be provided with a sleeve which surrounds a snout at one axial end of the crankshaft. Alternatively, the damper can be installed in or on or can constitute a cheek of the crankshaft. The coil springs can operate in parallel with a friction generating device which also opposes rotation of the input element and the mass of the damper relative to each other.

A clutch disc wherein two annular washer-like friction linings flank a two-part resilient cushion which moves the friction linings apart during disengagement of a friction clutch wherein the clutch disc is installed between an engine-driven flywheel and an axially movable pressure plate, and which stores energy during engagement of the clutch. A blocking or movement limiting device, which defines a fulcrum for the friction linings, is provided between the parts of the cushion and/or on the friction linings to prevent an axial movement of the friction linings toward each other beyond a selected minimum distance and to thus compensate for deformation of the flywheel and/or pressure plate as a result of heating attributable to slippage of the pressure plate and flywheel relative to the adjacent friction linings during engagement and disengagement of the clutch.
