  • Patent number: 11046166
    Abstract: A hybrid module has an intermediate element via which a counter plate, or at least one of the counter plates, of a coupling device is fixedly connected to a rotor element. At least one pressure plate and/or intermediate plate of the coupling device is here connected rotationally fixedly but axially displaceably to the rotor element via the at least one intermediate element. The result is a compact plate connection which is advantageous in particular for multiplate clutches. The intermediate element may be arranged radially outside the plates (pressure plate(s), counter plate(s) and any intermediate plates) of the coupling device.

  • Patent number: 10913343
    Abstract: A hybrid module for coupling an internal combustion engine in a motor vehicle includes an axis of rotation, an electric machine, a space, and a clutch. The electric machine has a rotor arranged on the axis of rotation. The space is surrounded by the rotor. The clutch is for transmitting a torque from a drive assembly. The clutch is arranged in the space surrounded by the rotor and includes a rotational part fixed to the rotor and arranged on the axis of rotation. The rotational part extends further radially from the axis of rotation than the rotor such that a heat introduced into the rotational part from the rotor or the clutch can be discharged.

  • Patent number: 8180309
    Abstract: A lock-in amplifier with an additional phase-sensitive detector is provided. A measurement signal is mixed in a multiplicative fashion with a reference signal, which is phase-shifted by 90 degrees, for a modulation frequency. In order to reliably filter out interference signal portions in a widest possible dynamic range and, at the same time, minimize unavoidable influence on the useful signal portion, a control device is connected downstream of the additional phase-sensitive detector. The control device determines a control variable corresponding to the strength of the interference signal from the measurement signal mixed with the reference signal phase shifted by 90 degrees and uses the control variable to change the integration duration of the integrator proportionally to the control variable, a corresponding cut-off frequency of an equivalent low pass being coordinated automatically.

  • Patent number: 7766142
    Abstract: A torque transmission device for the application in the drive train of a vehicle, between a driven shaft of a drive unit and a transmission, with at least two transmission input shafts. The torque transmission device includes at least two friction clutches which respectively feature a clutch disc, which can be coupled respectively with one of the transmission input shafts, and an intermediate pressure plate disposed between the friction lining of the twin clutch discs. The friction lining of both clutch discs may be clamped respectively between the intermediate pressure plate and one pressure plate, in which the respective pressure plates are disposed on the side of the friction lining that faces away relative to the intermediate pressure plate, still the two pressure plates with the intermediate pressure plate are at least rotationally coupled and are axially displaceable by actuation elements relative to the latter, in which at least the two friction clutches form a preassembled clutch assembly.

  • Publication number: 20090014270
    Abstract: A clutch unit including at least one friction clutch having a pressure plate and an opposed pressure plate between which the friction linings of a clutch disk are clampable. A lever system pivotable in an axial direction is provided on an opposite side of the opposed pressure plate and can be actuated to engage the clutch. The lever system is tiltable about an annular-shaped bearing that is supported by the opposed pressure plate. The lever system is also connected radially outwardly to the opposed pressure plate via a spring. The bearing is supported on an adjusting ring of an adjusting device to compensate at least for the wear that occurs on the friction linings of the clutch plate, which is rotatable relative to the pressure plate.

  • Publication number: 20080308379
    Abstract: A clutch unit having at least one friction clutch including a pressure disk joined to a housing in a rotationally fixed but axially displaceable manner. A lever system that can pivot axially is arranged between the housing and the pressure disk and can be impinged upon by an actuation device to engage the clutch. An adjusting device that at least partially compensates wear and tear of the friction lining of the clutch engages between the lever system and the housing. The lever system is axially supported on the housing by a rotatable adjusting ring and can be impinged upon in an axial manner in the direction of the adjusting ring by spring elements to produce an axial supporting force that is opposite to the clutch closing pressure applied to the lever system. A force-path characteristic is produced that reduces at least in the working area, wherein the spring elements are deformed for the at least partial wear and tear compensation.

  • Patent number: 7066313
    Abstract: A friction clutch wherein a rotary housing supports a tiltable diaphragm spring and confines a pressure plate that is axially movably but non-rotatably mounted therein for movement toward and away from friction linings on a clutch disc between the pressure plate and a prime-mover-driven counterpressure plate. The diaphragm spring is arranged to urge the pressure plate in a direction to engage the clutch and is maintained in stressed condition within the housing, even when not installed in the power train of a motor vehicle. The diaphragm spring is installed so that it is operatively associated with the pressure plate in an elastically stressed condition. The pressure plate includes an annular portion that supports the diaphragm spring, and further supports a biasing arrangement that is radially offset relative to the supporting portion and that serves to maintain the diaphragm spring on the pressure plate in the resiliently stressed condition.

  • Patent number: 6601682
    Abstract: A power train between the output shaft of the engine and the input shaft of the transmission in the power train of a motor vehicle has a composite flywheel receiving torque from the output shaft and transmits torque to the input shaft by way of a clutch disc in response to engagement of a friction clutch which is arranged to transmit torque between the clutch disc and the flywheel. The clutch disc has an input section adapted to receive torque from the flywheel and an output section adjacent the mass of a dynamic damper. Transmission of torque between the mass and the clutch disc takes place by way of the coil springs of an oscillation damper and a slip clutch in series with the oscillation damper.

  • Patent number: 6405846
    Abstract: A friction clutch wherein a pressure plate is axially movably but non-rotatably coupled to a cover and is biased by a diaphragm spring to urge the friction linings of a clutch disc against a flywheel which is driven by the engine of a motor vehicle. The diaphragm spring is tiltable relative to a seat which is carried by the cover, and a second spring is provided to bias a portion of the seat against the diaphragm spring. The latter can be moved axially of the flywheel to compensate for wear upon the friction linings, particularly when the flywheel is idle or is driven at a relatively low speed.
