Patent number: 5279183Abstract: According to an illustrative example of the invention, a flywheel is screwed to a crankshaft by a central bolt. The flywheel and the crankshaft are further provided with radially extending teeth in opposite annular contact faces. These teeth are engaged such as to center the flywheel with respect to the crankshaft and to permit torque transmission between the crankshaft and the flywheel. An angular positioning pin of the flywheel engages into a pin receiving bore of the crankshaft.Type: GrantFiled: April 19, 1991Date of Patent: January 18, 1994Assignee: Fichtel & Sachs AGInventors: Andreas Forster, Peter Weber, Bernhard Schierling, Dieter Kolb, Harald Jeppe, Hilmar Goebel

Patent number: 5251736Abstract: A clutch plate for a motor vehicle friction clutch is proposed in which a lateral disc of a load torsional vibration damper of the clutch plate is radially centered on spring tongues which extend and project either axially or peripherally from a hub of the clutch plate. The spring tongues extend into a central opening in the lateral disc, and the spring tongues rest in the central opening under radial tension. Radially acting stops on the hub can be provided peripherally between the individual spring tongues to limit the spring travel.Type: GrantFiled: December 8, 1992Date of Patent: October 12, 1993Assignee: Fichtel & Sachs AGInventors: Harald Jeppe, Matthias Fischer, Martin Langfeldt, Peter Schultes, Winfried Feller

Patent number: 5249660Abstract: The clutch disc for a motor vehicle friction clutch comprises a hub (1) on which side discs (7, 9) are rotatably mounted, arranged axially spaced, rigidly joined together, carrying the clutch linings (17). A hub plate (19) joined with the hub (1) solid in rotation, but with rotary play, is coupled rotationally elastically by means of springs (23) with the side discs (7, 9). Mounted axially between the hub plate (19) and one of the side discs (7) is a friction ring (41) of plastic material from which there protrude lugs (39) engaging into recesses (61) of the side disc (7). The lugs (39) guide the friction ring (41) solid in rotation but axially movable on the lateral disc (7). Axially mounted between the frictional ring (41) in frictional contact with the hub plate (19) and the side disc (7) is a disc spring (43) which applies with a plurality of flexible tongues protruding from its inner circumference on the friction ring (41). The flexible tongues engage in recesses of the friction ring (41).Type: GrantFiled: March 5, 1992Date of Patent: October 5, 1993Assignee: Fichtel & Sachs AGInventors: Reinhard Feldhaus, Matthias Fischer, Harald Jeppe

Patent number: 5213188Abstract: A clutch disk for a motor vehicle friction clutch is proposed of which the torsional vibration damper, designed for idle running, is arranged radially between a hub and springs of a torsional vibration damper designed for load running. The idling damper is arranged axially between a hub disk and one of the lateral disks of the load damper torsionally elastically coupled to the hub disk. The idling damper comprises an input part, produced from plastics material, which is non-rotatably connected to the hub disk coupled with rotational play but otherwise non-rotatably to the hub. The output part of the idling damper also consists of plastics material and is non-rotatably connected to the hub. Helical springs, couple the output part torsionally elastically to the input part. Pairs of projections, shaped on the input part, enclose the springs between themselves and are supported through the pockets on the hub disk.Type: GrantFiled: March 5, 1992Date of Patent: May 25, 1993Assignee: Fichtel & SachsInventors: Erich Feser, Harald Jeppe, Matthias Fischer

Patent number: 5209334Abstract: A clutch disc with torsional vibration damper is proposed in which synthetic plastics material guide parts are arranged between a hub disc protruding from a hub and two side discs arranged axially on both sides of the hub disc, which guide parts, stressed axially by a spring, fix the side discs axially on the hub disc and guide them radially on the hub, by means of formed-on collars. The guide parts are coupled rotationally elastically through springs of an idling damper with the hub disc and at the same time determine the friction moment in idling.Type: GrantFiled: September 6, 1991Date of Patent: May 11, 1993Assignee: Fichtel & Sachs AGInventors: Matthias Fischer, Harald Jeppe, Gerda Rudolph

Patent number: 5167310Abstract: The invention relates to the production of a multi-part hub part for a clutch disc, wherein all parts are joined together by a weld. Different designs are possible, depending on the various welding processes. The apertures for damper springs can be produced very exactly in the hub disc owing to the production in individual parts. It is also possible to arrange lubricant reservoirs in a simple manner in the region of the points of separation of the individual components.Type: GrantFiled: April 5, 1991Date of Patent: December 1, 1992Assignee: Fichtel & Sachs AGInventors: Matthias Fischer, Peter Wiggen, Harald Jeppe

Patent number: 5016744Abstract: It is proposed for the clutch disc of a motor vehicle friction clutch that one of the lateral discs of a torsional vibration damper of the clutch disc be mounted via a radially resilient mounting ring on a cylindrical bearing face of a hub of the clutch disc. The mounting ring has a closed annular part which is fixed radially and axially in a central opening of the lateral disc and, on its internal periphery, has a substantially conical, preferably radially slotted, radially resilient connecting region. On its internal periphery, the connection region is provided directly or via a shaped-on tube region with a cylindrical opposing bearing face which rests substantially without initial tension on the bearing face of the hub. Spacer blocks limit the radial spring path and are used for the non-rotational guidance of the mounting ring on the lateral disc.Type: GrantFiled: January 23, 1990Date of Patent: May 21, 1991Assignee: Fichtel & Sachs AGInventors: Matthias Fischer, Rainer Wiedmann, Kurt Fadler, Harald Jeppe

Patent number: 4903812Abstract: The invention relates to a clutch disc including an idling damping device and an under-load damping device, wherein the idling damping device is active between two hub parts coupled with each other by a toothing having play in the circumferential direction. In order to avoid the load-change impact, centrifugal weights are provided between the two parts. The centrifugal weights frictionally couple the two parts by means of a self-intensifying effect.Type: GrantFiled: May 26, 1988Date of Patent: February 27, 1990Assignee: Fichtel & Sachs AGInventors: Matthias Fischer, Harald Jeppe
