A torsional vibration damper arrangement including a torsional vibration damper with a primary side and a secondary side rotatable with respect to the primary side around an axis of rotation against the action of a damper spring arrangement. One side of the primary side and secondary side includes two cover disk elements and a central disk element arranged between the cover disk elements. The cover disk elements are connected to one another by first connection elements radially inside the damper spring arrangement so as to be fixed axially and so as to transmit torque. The cover disk elements are connected to one another by second connection elements in such a way that they are prevented from moving axially away from one another. No torque can be transmitted between the cover disk elements by the second connection elements.

Torsional vibration damping arrangement, particularly for the power train of a vehicle

A clutch disk is provided having a connecting arrangement, by means of which the friction linings can execute a radial movement with respect to the hub rotation axis and/or tilting movement with respect to a plane orthogonal to the hub rotation axis.

Clutch disk for a motor vehicle friction clutch

A torsional vibration damping device in the drive train of a motor vehicle has two coaxial cover plates which are rotationally connected and are kept at a distance apart. The two coaxial cover plates rotate about a common axis of rotation within a certain angular range relative to a coaxial internally located part arranged between the two cover paltes and the cover plates are elastically connected to the internally located part by a spring element which is effective in the circumferential direction. The cover plates are held apart by distance pieces applied transversely to the circumferential direction. Each distance piece has a joint region where the distance piece is connected to the cover plate and a connecting region which traverses the distance between the cover plates. The radial distance between the joint region and the axis of rotation differs from the radial distance between the connecting region and the axis of rotation.

A clutch disk for a motor vehicle, in which a centering force is applied between the input parts and the output parts in operating states in which the input parts, relative to the output parts, carry out a wobbling movement or undergo a radial displacement, a spring element arranged between one cover plate and the hub disk and which is centered directly or indirectly at the cover plate or hub disk. A bearing ring is arranged with an outer contour between the spring tongues and the bearing region of the hub. The inner contour of a structural component part of the one coverplate is arranged at a distance from this outer contour for determining the movement play of the spring tongues of the spring element.

Clutch disk with flexible bearing

A clutch disk for a friction clutch, especially for internal combustion engines, with a hub, two friction disks which are arranged concentric to the hub and are connected thereto. A plurality of facing spring elements are connected with the friction disks so as to be rotationally fixed relative thereto, and are provided between the friction disks in the circumferential direction. The facing spring elements are curved in a wavy manner and nested against one another in pairs such that they exert a force on the friction disks in the axial direction. The facing spring elements which are nested against one another are designed so that their ends which are directed in the circumferential direction are located at a distance from one another in the no-load state of the clutch.

Clutch disk with a double facing spring

A clutch disc includes an elastic mounting to absorb both wobbling movement and to compensate for axially offsetting transmission components. Between the hub and the components which can rotate with respect to the hub, there is a spring element which makes it possible by means of two different types of fingers to accomplish both a radially elastic centering and an axially elastic clamping. The clutch disc can thereby absorb both wobbling movements and axial offsets.

Clutch disc with elastic mounting

Torsional vibration damper for a motor vehicle friction clutch, the torsional vibration damper having a hub with a hub disc, and cover plates located one on either side of the hub disc, which cover plates are fastened together. The cover plates can be rotated with respect to the hub disc against the force of springs by a specified amount, whereby the radial guidance of the parts which can rotate in relation to one another is provided by preferably one cover plate and a bearing element inserted in a central hole of the cover plate. The bearing element permits a limited radial relative movement of the cover plate with respect to the hub, is designed so that in addition to an axial offset, it can also compensate for an angular offset between the crankshaft and the transmission shaft.

Motor vehicle friction clutch with a torsional vibration damper, and a

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.

Friction clutch for a drive train of a motor vehicle and a torsional

This invention relates to a clutch disc with a torsional vibration damper, in which a control plate is used which, after a specified angle of rotation, comes into contact with the aperture of a spring element. Additional friction surfaces can be activated as a result of the presence of a control plate, which is capable of coming into contact on one of the components, i.e. the input part or the output part, with a friction element which is connected non-rotationally to the other of the two components.

Clutch disc with torsional vibration damper

The present invention generally relates to a clutch disc for a friction clutch, in which two identical cover plates are used, each of which has areas with different outside diameters, whereby the area with the larger diameter has the openings for fastening rivets for lining carriers and the openings for the location of balancing rivets, and the areas with the smaller diameter make it possible to have access with a tool for peening the rivet heads from the other side. The individual cover plates are also assembled to one another in mirror inversion.

Clutch disc with balancing rivets

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.

Friction clutch for a transmission of a motor vehicle and a clutch disc

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.

Friction clutch for a transmission of a motor vehicle and a torsional

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.

Transmission for a motor vehicle with a friction clutch having a clutch

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.

Clutch plate for a motor vehicle friction clutch

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. The blocks (43, 45) of the second and third set define internal diameters (D1, D3) which are greater than the internal diameter (D1) of the first set, the internal diameter (D3) of the third set being smaller than the internal diameter (D2) of the second set. The blocks (45) of the third set rest via the annular part (29) directly on the central opening of the lateral disc and restrict the spring travel of the radially resilient blocks (41) of the first set. The blocks (43) of the second set which are not directly radially supported owing to radial tolerances of the lateral discs in the region of the noses (33) are therefore used to restrict the spring travel of the blocks (41) of the first set only after the blocks (45) of the third set are worn.
