  • Patent number: 10059186
    Abstract: 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.

  • Publication number: 20180091010
    Abstract: An electric motor for a hybrid drive of a vehicle comprises a rotor and a stator. The stator surrounds the rotor and the rotor is fastened to a rotor carrier. A rotor laminated core of the rotor is connected to the rotor carrier by a tongue-and-groove connection and a transverse interference fit. To form the transverse interference fit, the rotor laminated core may have, for bracing on the rotor carrier, a smaller radius than the rotor carrier.

  • Publication number: 20170050506
    Abstract: The invention relates to a torque transmission device that is to be arranged in a drive train of a hybrid vehicle having an internal combustion engine, a transmission and an electric machine, the electric machine being arranged in the torque transmission device. The torque transmission device includes a disconnect clutch with clutch actuation, for decoupling the internal combustion engine from the transmission, and a primary torsional vibration damper on the crankshaft side. The invention has a secondary torsional vibration damper arranged on the transmission side, radially and axially inside the rotor and directly on the transmission-side output flange of the torque transmission device. This allows the installation space for the crankshaft-side primary torsional vibration damper to be increased, such that the damper can be optimally designed.

  • Patent number: 9108637
    Abstract: 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.
