Abstract: A friction clutch for a drive train of a motor vehicle generally has a torsional damper with at least one hub and hub disc concentric to an axis of rotation, and cover plates located on both sides of the hub disc which are non-rotationally connected together and held at a distance from one another. Coil springs can be located in apertures of the hub disc, on one hand, and in the cover plates on the other hand. The apertures can be designed so that the coil springs, located in the apertures of the cover plates, in spite of the fact that the coil springs are held without stress on their ends, cannot come loose from the apertures. To achieve this, the edges with which the ends of the respective coil springs come in contact can be provided with indentations which are designed for the radial release of the respective outermost windings of the coil springs.

Abstract: A transmission of a motor vehicle can have a friction clutch with a torsional vibration damper and a clutch disc. In the friction clutch there can be a control plate for the control of a friction action as a function of the torsion angle, which control plate can be centered in one direction perpendicular to the axis of rotation by means of at least two diagonally opposite stop edges. The stop edges preferably can interact with two opposite-facing end surfaces of the coil springs within the clutch disc. It can thereby be possible to center the control plate independently of the guide diameter of the hub.

Abstract: A friction clutch can typically have a rotary power input member which can be rotationally engaged by means of a torsional damping device such as springs located between the input and output members. The output member can include a hub, non-rotationally connected to a hub disc, and the input member can include at least one disc-shaped member disposed adjacent the hub disc, which disc-shaped member can have friction linings for engaging a rotating part of an engine. The torsional damping device can include a base friction apparatus and a load friction apparatus for which friction rings are used, which rings have an internal axial stress and generate the frictional force as a result of their material properties and their axial friction mounting.

Abstract: A clutch disc with a basic friction device, which can have a corresponding friction ring with axial projections that torsionally lock with the toothing of the hub, for transmission of the torque to the hub disc.

Abstract: The invention relates to a clutch plate with a torsional vibration damper in which there is provided an entrained friction arrangement which acts before the transition from idling spring action into load spring action. During a reversal of the direction of rotation, the entrained friction arrangement is carried by frictional force and it runs through its free angle only during the transition from the load spring arrangement into the idling spring arrangement.

Abstract: In order to mount the lateral discs of a clutch plate, provided with a torsional vibration damper, of a motor vehicle friction clutch on a hub, there is provided a plastic ring (23) which is inserted with an annular part (29) into a central opening in one of the lateral discs. The plastics ring (23) has a plurality of sets of radially inwardly projecting blocks (41, 43, 45), separated from one another by slots (46), with a cylindrical segment-shaped internal contour (47). The blocks (41) of a first set are radially resilient and define an internal diameter (D1) such that these blocks can rest without radial pretension on the external contour of the hub. The blocks (43) of a second set pass into the noses (33) provided to prevent rotation and, like the blocks (45) of a third set, are not resilient.

Abstract: The invention relates to a clutch disk for a friction clutch in which a load and an idling system are provided. The idling system is bridged over by teeth (2a, 4) in the load system. A load friction disk (23) which simultaneously makes direct contact with one (11) of the two covering plates as well as the associated hub disk (12) is provided for producing a two-staged frictional force in the idling system. Owing to different material constitutions of the load friction disk (23) on opposing sides or owing to different material of the load friction disk (23) and the hub disk (12) it is possible to produce a jump in the frictional force. The load friction disk (23) is controlled primarily by stop edges, and additional control can be provided by a spring for the idling range, which is used after a predetermined angle of rotation.

Abstract: The clutch disc for a motor vehicle friction clutch comprises a hub on which a driving disc provided with friction linings is coaxially rotatably mounted through a torsional vibration damper. The torsional vibration damper has two mutually relatively rotatable damper parts which are rotationally elastically coupled with one another through springs. One of the damper parts is guided rotatably on the hub through at least one rolling bearing. The rolling bearing reduces especially the friction occuring in idling operation.

Abstract: In a torque transmitting torsional vibration damper device for use in a torque transmission path of a motor vehicle between the engine and the gear box a central plate is provided. Two sides plates are provided on both sides of the central plate. The side plates are interconnected for common rotation. Each of the central plate and the side plates is provided with at least two circumferentially extending windows. Respective windows of the central plate and the side plates are aligned in axial direction. Each group of mutually aligned windows receives a pair of torque transmitting compressional springs arranged in series and spaced in circumferential direction. Said discs are provided between the central plate and the side plates. These sides discs are used for circumferential torque transmission between mutually adjacent ends of the compressional springs of each pair. The side discs are supported in radial direction only by engagement with the compressional springs.

Abstract: The clutch disc comprises for torsional vibration damping a spring system (35) dimensioned for operation under load and a spring system (51, 53) dimensioned for operation in idling. An idle motion device (5, 7) ensures that in the case of relative rotation angles in the idling operation the idling spring system (51, 53) exclusively is effective. In order to avoid jumps in the spring characteristic of the spring systems in the transition from idling operation to under-load operation, the idling spring system (51, 53) comprises at least one spring (53) which is brought into action within the rotation angle range of the idle motion device (5, 7) on approach to the under-load range and increases the spring rating of the idling spring system. Thus clutch and gear noises in this transitional range are avoided.

Abstract: According to an example embodiment of this invention, a clutch disc comprises a primary hub, a seconday hub and a lining carrier. The primary hub is angularly movable with respect to the secondary hub and the secondary hub is angularly movable with respect to the lining carrier. First load transmitting springs are provided between the primary hub and the secondary hub. Second load transmitting springs are provided between the secondary hub and the lining carrier. The second springs have a steeper spring characteristic than the first springs. Abutments are provided on both the primary hub and the secondary hub. The second springs are pre-stressed. When an increasing load is transmitted the angular movement of the secondary hub with respect to the lining carrier begins before the abutments of the primary and the secondary hubs engage each other.

The torsional vibration damper (1) comprises two damper units (2, 6, 10 and 3, 7, 11, 12) connected in series with one another into the torque transmission path.

Abstract: The clutch disc for a motor-vehicle friction clutch has a hub which defines an axis of rotation and from which there projects substantially radially a hub disc so as to be secured against rotation. On the hub there is mounted, so as to be rotatable through a limited angle of rotation, a friction lining carrier which comprises two side parts which are arranged on axially opposite sides of the hub disc and which are non-rotatably connected to each other and to the carrier. In the rotational path between the side parts and the hub disc there are arranged springs which are subjected to pressure during the relative movement of the friction lining carrier and the hub. Axially on both sides of the hub disc friction rings are arranged between the hub disc and the adjacent side parts. Between one of the two friction rings and the adjacent side part there is provided a pressure ring from which there project substantially radially several arms which are stiff in the circumferential direction of the pressure ring.

Abstract: The clutch disc for a motor vehicle friction clutch comprises a hub with side discs arranged axially on both sides of its hub flange and connected with friction linings into one unit. The side discs are rotatable in relation to the hub disc by the stressing of springs. An under-load friction damper comprises two control discs arranged axially on both sides of the hub disc, one of which comprises axial tabs which pass through openings of the hub disc. The other control disc is guided non-rotatably but axially displaceably on the tabs. Friction rings are arranged axially between the side discs on the one part and the control discs on the other. The friction force is generated by a dished spring which is clamped axially resiliently in between the axial tabs of the one control disc and the axially movable other control disc utilized as pressure disc. An idling friction damper is accommodated between the side discs protected radially within the zone radially defined by the tabs.

Abstract: In a clutch disc, a flange disc is secured to and projects radially outwardly from an axially extending hub. A friction lining carrier projects radially outwardly from the hub and for a portion of its radial extent it is coextensive with the flange disc. Circumferentially extending springs are seated between stop faces on the flange disc and the friction lining carrier and limit the rotational movement of the carrier relative to the flange disc. Friction members are positioned between the friction lining carrier and the flange disc. One or more contact members are positioned between the friction lining carrier and the flange disc with the contact member being rotatable relative to the friction members.
