摘要： The disclosure describes a clutch assembly that includes a first clutch element coupled to an input shaft and including a first clutch element friction surface; a second clutch element coupled to an output shaft, and a brake clutch coupled to a stationary component. The second clutch element includes a first friction surface configured to engage the first clutch element friction surface and a second friction surface opposite the first friction surface. The second clutch element is configured to move relative to the first clutch element to engage and disengage the first friction surface and the first clutch element friction surface. The brake clutch includes a brake clutch friction surface configured to engage the second friction surface of the second clutch element when the first clutch element and the second clutch element are disengaged.

摘要： A motor vehicle drive apparatus includes a device configured to connect an internal combustion engine to an electromechanical energy converter, and first and second drive trains. The second drivetrain is arranged parallel to the first drivetrain in relation to torque transmission between the electromechanical energy converter and the internal combustion engine. The first drivetrain has a one-way clutch which is set up in such a manner that torque is transmittable via the first drivetrain from the electromechanical energy converter to the internal combustion engine during starting of the internal combustion engine. The second drivetrain has a speed-sensitive clutch which in a first state is open until a first speed threshold is reached, so that in the first state no torque is transmittable with the second drivetrain from the internal combustion engine to the electromechanical energy converter. The speed-sensitive clutch is closed from the crossing of this first speed threshold.

摘要： A hybrid-vehicle system includes an internal combustion engine configured to deliver a first rotational torque to a crankshaft. The first rotational torque is a maximum torque deliverable by the internal combustion engine. The hybrid-vehicle system also includes a transmission selectively rotatably coupled to the crankshaft, and an assembly including an electric machine rotatably coupled to the transmission and configured to deliver a second rotational torque directly to the transmission. The assembly also includes a one-way clutch configured to rotationally couple the crankshaft and the transmission. The assembly further includes a friction clutch moveable between an engaged state where the crankshaft and the transmission are rotationally coupled, and a disengaged state where the crankshaft and the transmission are rotationally decoupled. In the engaged state, the friction clutch is limited to delivering 85% or less of the first rotational torque to the transmission.

摘要： A power transmission device for a vehicle includes a first power transmission path that is provided between an engine and a driving wheel, a second power transmission path that is provided in parallel with the first power transmission path, and an electronic control unit. The electronic control unit changes over a secondary clutch to a one-way mode while releasing a first clutch, when a request is made to change over a power transmission path between the engine and the driving wheel from the first power transmission path to the second power transmission path at a time of a predetermined state. The electronic control unit is configured to engage a second clutch when the secondary clutch is changed over to the one-way mode.

摘要： A friction clutch for releasable transmission of a torque between a first drive unit and a second drive unit includes a rotational axis, a friction package for transmitting the torque in a pressed state, a first actuating element, and a second actuating element. The friction package has at least one friction plate and at least one friction disk. The first actuating element is arranged on a first side of the friction package for pressing the friction package in a first axial actuating direction to achieve the pressed state, and the second actuating element is arranged on a second side of the friction package, opposite the first side, for pressing the friction package in a second axial actuating direction, opposite the first axial actuating direction, to achieve the pressed state.
