Patent number: 5732810Abstract: A friction clutch has an inertia mass attachable to a drive, a housing that serves to accommodate a pressure spring as well as a pressure plate, and a ring that encompasses the rotational axis of the inertia mass and housing and acts, in connection with a signal receiver, as a pulse generator. This ring, because it is not very thick in the radial direction, can be deformed by even small radial forces, so that its inner diameter can be adapted by enlargement or shrinking to the outer diameter of a component intended for its accommodation, such as an inertia mass or housing, in order to establish a friction locking connection between the ring and the outer diameter of the component.Type: GrantFiled: September 5, 1996Date of Patent: March 31, 1998Assignee: Fichtel & Sachs AGInventor: Heiko Schulz-Andres

Patent number: 5404979Abstract: A manual transmission modular clutch assembly has a flywheel, pressure plate and interposed clutch plate mounted in a cover that is adapted to be connected to an engine crankshaft and wherein separate spring-torque straps connect the pressure plate and the flywheel to the cover for rotation therewith. At assembly the flywheel is positioned against the force of its spring-torque straps by travel limit pins that are retained on the cover, press fitted in the flywheel and contact with the pressure plate when in its clutch engaging position. A diaphragm spring normally clamps the pressure plate, clutch plate and flywheel together and is adapted to be connected to a clutch pedal to release the clutch. As wear occurs, the pressure plate is allowed to move further in the direction of the flywheel and forces the flywheel travel limit pins to move in their press fit by the same amount.Type: GrantFiled: May 27, 1994Date of Patent: April 11, 1995Assignees: Chrysler Corporation, Sachs Automotive of AmericaInventors: Barrie G. Craft, Joseph L. Bair, Michael B. Grosse Erdmann, Edwin R. Murray, George S. Traub, Gerda Rudolph, Peter Doll, Heiko Schulz-Andres, David G. Buckingham, Richard G. Reed

Patent number: 5377803Abstract: A pressure plate arrangement (1) for a friction clutch of a motor vehicle is proposed, wherein an adjustment device (19), which automatically compensates for the wear of the friction linings (21), is disposed in the support path between a diaphragm spring (13) and a pressure plate (11), stressed against a flywheel (1) by the diaphragm spring (13) via friction linings (21) of a clutch disk (23). The adjustment device (19) has a pressure path compensating member (31), for example in the form of a radially resilient cone-shaped ring, which automatically compensates for possible play between the diaphragm spring (13) and the pressure plate (11). Distributed in the circumferential direction, a plurality of play transfer devices (37) is axially movably guided and arrested (for example by self-locking). The play transfer devices (37) rest against the flywheel (1) of the clutch housing (9) fixedly connected therewith and have levers (43) which limit the maximal wear compensation path of the compensating member (31).Type: GrantFiled: May 4, 1993Date of Patent: January 3, 1995Assignee: Fichtel & Sachs AGInventors: Achim Link, Reinhold Weidinger, Heiko Schulz-Andres, Klaus Elsner, Rainer Wiedmann, Ralf Nenninger, Michael Weiss
