Patent number: 7066313Abstract: 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.Type: GrantFiled: April 10, 2004Date of Patent: June 27, 2006Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Karl-Ludwig Kimmig, Philippe Mih, Mathieu Jordan

Patent number: 6601682Abstract: 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.Type: GrantFiled: April 18, 2001Date of Patent: August 5, 2003Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Stefan Lehmann, Karl-Ludwig Kimmig, Roland Seebacher, Friedrich Gerhardt, Joachim Hoffman, Hermann Langeneckert

Patent number: 6305520Abstract: A friction clutch wherein a pressure plate is movable axially of and rotates with a housing which is driven by the engine of a motor vehicle. The pressure plate cooperates with a coaxial engine-driven counter-pressure plate to bear upon the respective friction linings of a clutch disc when the clutch is engaged to drive the input shaft of a transmission in the power train of the vehicle. A diaphragm spring is tiltable relative to an annular seat at the inner side of the housing and urges the pressure plate against the adjacent friction linings when the clutch is engaged. An automatic wear compensating unit serves to move the diaphragm spring and the seat axially relative to and away from the inner side of the housing to thus compensate for wear upon the friction linings. The diaphragm spring has resilient prongs which bear, directly or indirectly, upon portions of the housing to urge the diaphragm spring against the seat and to thus bias the seat toward the inner side of the housing.Type: GrantFiled: September 27, 2000Date of Patent: October 23, 2001Assignee: LuK Lamellon und Kupplungsbau GmbHInventors: Karl-Ludwig Kimmig, Michael Wachtel

Patent number: 6273229Abstract: A friction clutch wherein a damper which operates with friction between the housing and the clutch spring serves to minimize or to prevent axial stray movements of the diaphragm spring relative to the housing. This eliminates chatter and/or other forms of noise which unrestricted axial oscillatory movements of the diaphragm can cause in a conventional friction clutch or in a power train employing a conventional friction clutch.Type: GrantFiled: March 9, 2000Date of Patent: August 14, 2001Assignee: LuK Lamellen und Kupplungsbau GmbHInventor: Karl-Ludwig Kimmig

Patent number: 6098772Abstract: A friction clutch wherein an adjusting device serves to compensate for wear at least upon the friction linings of the clutch disc between the driven counterpressure plate and the axially movable pressure plate. The purpose of the adjusting device is to ensure that the bias of the clutch spring upon the pressure plate remains at least substantially unchanged. The adjusting device satisfies such requirement due to the provision of a device which compensates for departures of the actual position of the clutch actuating unit from an optimum position or which compensates for the departures of those portions of the actuating unit relative to a clutch disengaging member from an optimum position which are acted upon by the actuating unit.Type: GrantFiled: March 3, 1997Date of Patent: August 8, 2000Assignee: LuK Lamellen und Kupplungsbau GmbHInventors: Karl-Ludwig Kimmig, Christoph Wittmann, Wolfgang Reik, Paul Maucher, Rolf Meinhard
