A pendulum rocker damper with a rotation axis includes an input side with first and second input-side counter tracks, an output side with first and second output-side counter tracks, a stored energy source, and rocker elements disposed at opposite axial ends of the stored energy source. Each of the rocker elements has three axially offset partial tracks forming an input-side roller track and an output-side roller track. A first input-side rolling element is clamped between the first input-side counter track and a first input-side roller track and a second input-side rolling element is clamped between the second input-side counter track and a second input-side roller track. A first output-side rolling element is clamped between the first output-side counter track and a second output-side roller track and a second output-side rolling element is clamped between the second output-side counter track and a second output-side roller track.

A drive system () having a unipolar machine () and a fuel cell () for supplying the unipolar machine () with electrical energy. The fuel cell () can be arranged in a ring shape around a rotor shaft () of a rotor () of the unipolar machine ().

Drive system, and motor vehicle

A method for determines the drive train sensitivity of a drive train of a motor vehicle. A vehicle body is placed in longitudinal oscillations in the direction of travel and a parameter for the drive train sensitivity is determined as a function of the determined longitudinal accelerations of the vehicle body and the resultant angular accelerations of a transmission input shaft of a transmission of the motor vehicle.

Method for determining the drive train sensitivity of a drive train of a motor vehicle

A dual clutch having a first clutch which has a first pressure plate that is movable axially relative to a first counterplate for coupling a first clutch disk that is connected to a first output shaft, a second clutch, which has a second pressure plate that is axially movable relative to a second counterplate for coupling a second clutch disk that is connected to a second output shaft, a torsional vibration damper situated in the direction of flux force between the input shaft and the first counterplate wherein the torsional vibration damper includes a dual mass flywheel with a bow spring running in the circumferential direction to transmit torque, where the flux of force is introducible radially on the outside from the input shaft to the first counterplate into the dual mass flywheel, and is dispersible radially on the inside to the bow spring.

Dual clutch

A drivetrain having an active torsional vibration damping and a method for carrying out the active torsional vibration damping, having an internal combustion engine being affected by torsional vibrations and having a crankshaft, a torsional vibration damper that is operatively connected to the crankshaft and has at least one operating point of low vibration isolation of the torsional vibrations and has a primary inertial mass associated with the crankshaft and an inertial mass associated with a gear input shaft of a gearbox, the inertial mass being rotatable relatively and limitedly with respect to the primary inertial mass against the action of a spring device. The drivetrain also includes an electric motor having a rotating mass operatively connected to the gearbox input shaft, and a control unit, the spring device being formed by linear springs, the rotating mass of the electric motor being designed as a secondary inertial mass.

Hybrid drivetrain having active torsional vibration damping, and method for carrying out the active torsional damping

A drive train, which has an internal combustion engine with a crankshaft and a parallel shift transmission with two part drive trains, which each have one transmission input shaft. One shaft is formed as a hollow shaft around the other shaft, and a dual clutch, which is received rotatably on the hollow shaft, is connected to the crankshaft and has two friction clutches and two clutch plates each assigned to one clutch and are each connected to one transmission input shaft. Each clutch plate has a torsional vibration damper with a working range which is smaller than a maximum torque of the engine. A build-up of a combined vibration which has an axial vibration of the dual clutch and a rotational vibration of the drive train during an overlap shift operation is prevented by the design of the torsional vibration dampers for a smaller torque.

Method and device for controlling the slip of a vehicle clutch

In a method for setting the clutch torque of a clutch, especially a clutch disposed in a drive train of a motor vehicle, the clutch is adjusted using a clutch actuator. This clutch actuator has at least two actuator parts that may be positioned relative to each other at raster values of a position raster. A position setpoint corresponding to a clutch torque and disposed between the raster values of the position raster is calculated, and the actuator parts are positioned relative to each other at a raster value of the position raster that is adjacent to the position setpoint. In addition to the first position raster value, a second position raster value is calculated in such a manner that the position setpoint is disposed between the first position raster value and the second position raster value. The actuator parts are alternately positioned at the first position raster value and the second position raster value in such a manner that the average clutch torque more precisely matches the clutch torque setpoint than the clutch torques of the first and second position raster values.

Method for setting a clutch torque

An automatic friction clutch, contained in the drive train of a motor vehicle is controlled such that a preset clutch torque can be transmitted. The preset clutch torque is composed of a pilot clutch torque M and a clutch torque Msr, which is dependent on slip.

The invention relates to a torque transmission device, especially for a drive train comprising an internal combustion engine and a twin-clutch transmission having two transmission input shafts and one transmission output shaft, each transmission input shaft being connectable to an internal combustion engine via a clutch of the torque transmission device.

Torque transmitting unit and drive train for it

A powershift transmission is proposed using two transmission paths, a friction clutch being assigned to each transmission path and the transmission paths being coupleable to an output shaft for torque transmission. The transmission has a device that detects the clutch torque transmitted by the friction clutch of the active transmission path, which is coupled to the output shaft, and, when the clutch torque falls below threshold value, initiates a disengagement of the active gear ratio.
