Patent number: 6659254Abstract: A clutch disc, particularly for use between a pressure plate and a counterpressure plate in a friction clutch which is installed in the power train of a motor vehicle, has two friction linings flanking resilient carriers mounted on a washer which has a hub connectable with a torque receiving part, such as the input shaft of a change-speed transmission. The carriers are connected with reinforcing sections of the friction linings by rivets in such a way that the friction linings and the washer are movable radially relative to each other. This reduces the likelihood of excessive wear upon the friction linings in response to repeated engagement and disengagement of the clutch.Type: GrantFiled: February 14, 2002Date of Patent: December 9, 2003Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Martin Kraus, Hans-Dieter Elison, Rudolf Hönemann

Patent number: 6305522Abstract: A clutch disc wherein two annular washer-like friction linings flank a two-part resilient cushion which moves the friction linings apart during disengagement of a friction clutch wherein the clutch disc is installed between an engine-driven flywheel and an axially movable pressure plate, and which stores energy during engagement of the clutch. A blocking or movement limiting device, which defines a fulcrum for the friction linings, is provided between the parts of the cushion and/or on the friction linings to prevent an axial movement of the friction linings toward each other beyond a selected minimum distance and to thus compensate for deformation of the flywheel and/or pressure plate as a result of heating attributable to slippage of the pressure plate and flywheel relative to the adjacent friction linings during engagement and disengagement of the clutch.Type: GrantFiled: December 21, 2000Date of Patent: October 23, 2001Assignee: LuK Lamellen Kupplungsbau GmbHInventors: Jürgen Busse, Hans-Dieter Elison, Kraft Gunther, Steffen Lehmann, Andreas Raimann, Willi Ruder, Martin Schindler, Mario Thümmler, Albert Birk

Patent number: 5111924Abstract: A torsion damping apparatus between the crankshaft of the engine and the input shaft of the change-speed transmission of a motor vehicle has two flywheels one of which is driven by the crankshaft and the other of which drives the input shaft by way of a friction clutch which generates heat. In order to prevent the transfer of heat from the friction clutch to the antifriction bearing between the flywheels, which are rotatable relative to each other against the opposition of a damper, the bearing is at least partially surrounded by a thermal barrier of synthetic plastic, ceramic or metallic material which prolongs the useful life of the bearing and enhances the torsion damping action of the damper. The thermal barrier can constitute or form part of the damper.Type: GrantFiled: July 17, 1991Date of Patent: May 12, 1992Assignee: Luk Lamellen und Kupplungsbau GmbHInventors: Wolfgang Reik, Hans-Dieter Elison

Patent number: 4889009Abstract: A torque transmitting mechanism which operates between the crankshaft of the engine and the input shaft of the change-speed transmission in a motor vehicle has a first flywheel which is driven by the crankshaft, a second flywheel which can drive the input shaft through the medium of a friction clutch, and three series-connected dampers between the two flywheels. At least one of the dampers is a slip clutch, and the torque which can be transmitted by such slip clutch is variable. The dampers are designed to compensate for all fluctuations of torque which is transmitted between the crankshaft to the input shaft. The first damper can constitute a slip clutch the input element of which receives torque from the crankshaft, the second damper can constitute a slip clutch the input element of which is the output element of the first damper and the output element of which is the input element of an elastic damper operating between the second slip clutch and the second flywheel.Type: GrantFiled: December 18, 1986Date of Patent: December 26, 1989Assignee: LUK Lamellen und Kupplungsbau GmbHInventors: Oswald Friedmann, Hans-Dieter Elison
