Abstract: A torsional vibration damper including a disk-shaped first damper part, a second damper part which is rotatable about an axis with respect to the first damper part, and a torsion spring arrangement with at least one torsion spring unit. The at least one torsion spring unit includes at least two springs which are arranged substantially following one another in the circumferential direction. Further, there is at least one intermediate ring element which is rotatable about the axis with respect to the first damper part and the second damper part and with at least one spring contact arm for the at least one torsion spring unit. The spring contact arm extends substantially radially with respect to the axis. The at least one intermediate ring element has a radial movement restraining component for protecting the at least two springs against a movement in the radial outward direction in their end regions facing the at least one spring contact arm.

Abstract: In a clutch disk for a motor vehicle clutch, fixing members which are produced in one piece with carrier plates of friction linings and are provided to engage behind edges of a recess in an adjacent component have a base that covers the recess, this providing the fixing members with a particularly high stability. The number of fixing members may therefore be kept particularly low.

Abstract: A facing carrier of a driver disk for a clutch plate includes a plurality of segments situated at a slight distance from one another around a circumference of a reinforcement part. The segments are pretensioned against the reinforcement part during assembly and welded thereto. The spacing of the segments allows uniform pretensioning of the segments against the reinforcement part.

Abstract: A driver disk for a clutch plate includes a facing carrier for holding friction facings. The facing carrier is designed in one piece with facing springs for axial suspension of the friction facings. The facing springs are constructed as pot-shaped protuberances and have a flat area provided for contacting the friction facings. Since the facing springs are made as one piece with the facing carrier, the driver disk has only a small number of structural component parts and can be produced very economically.

Abstract: A rotational vibration damper, especially for arrangement in a drive train of a motor vehicle driven by an internal combustion engine, comprises first and second damping components that are rotatable together as well as relative to each other around a common rotational axis. The first and second damping components are connected to each other for rotational force transmission by a coupling mass arrangement. The coupling mass arrangement is connected to the first damping component so as to be pivotable about a pivot axis that is offset substantially axis-parallel to the center of gravity of the coupling mass arrangement and to the rotational axis. The coupling mass arrangement has two contact surface regions arranged at a distance from each other in the circumferential direction relative to the pivot axis and face away from each other.

Abstract: A torsional vibration damper has a plurality of transmission elements which are rotatable relative to one another about a common axis of rotation. The relative movement of the transmission elements is carried out by the deflection of coupling bodies which are displaceable between the transmission elements along guide paths. A first guide path is provided on at least one of the transmission elements enabling a movement of the respective coupling body in the circumferential direction. The first guide path has a curvature which is formed with a curvature location having the maximum distance from the axis of rotation. A second guide path substantially free of curvature is provided on at least another transmission element allowing a movement of the coupling body in the radial direction. The coupling body is substantially free of curvature at least along a predeterminable portion of a contact zone facing the second guide path.

Abstract: A clutch disk with two structural component groups which are arranged so as to be swivelably movable and radially movable relative to another within a defined scope by the intermediary of a guide element which is constructed as a helical spring and which is arranged concentric to the hub and whose turns--considered in the axial direction--are inclined at least in the installed state.

Abstract: A torsional vibration damper has a transmission element on the drive side and a transmission element on the driven side which is rotatable relative to the drive-side transmission element against the action of a damping device. The damping device serves to transmit torque between the two transmission elements and has at least one coupling body that moves along at least one guide path which is formed in one of the transmission elements. This coupling body is displaceable at least in the circumferential direction and is in a working connection with the other transmission element via a driver device so that a deflection of one of the transmission elements in the circumferential direction by a relative movement of the coupling body results in a deflection of the other transmission element. Each guide path is provided with a curvature having a curvature location at the maximum distance from the axis of rotation.

Abstract: A clutch disk with a torsional vibration damper, with an idling system and a load system. The clutch disk including a hub disk mounted with play on a hub via a toothing, cover plates arranged at both sides of the hub disk coaxially thereto, and pre-damper having springs. The hub disk being activatable via a friction arrangement. The friction arrangement has a friction ring which is supported at the hub on one side and at the springs of the pre-damper on the other side.

Abstract: A clutch plate in which the support of the hub provides for pivoting as well as radial compliance relative to the remaining components. This support is accomplished by a component, which is centered directly or indirectly on the hub plate of the load compliance, whereby the load springs can be employed for radial compliance of the hub.

Abstract: A clutch disk for a friction clutch, especially for motor vehicles, has a driver disk with friction facings and a cover plate which is connected with the driver disk so as to be fixed with respect to rotation thereto. A hub disk and at least one control plate provided with two diametral arms are held between the driver disk and the cover plate. The hub disk, the cover plate and the driver disk are provided with windows in order to receive springs. The windows provided in the hub disk have, on at least one circumferential edge, a recess extending substantially in the circumferential direction. The arms of the control plate are provided with stop tabs on the radially outer side. The stop tabs cooperate with the radial outer region of the springs and, in the region of the stop tabs, the windows in the hub disk are enlarged along the circumference corresponding to the material thickness of the stop tabs.

Abstract: A clutch disc for a motor vehicle clutch which has an input part and an output part with relative rotational play. A friction device is located between the input part and output part. The friction device includes a friction disc located non-rotationally on the input part or on the output part, which friction disc has friction areas which have different coefficients of friction around its periphery, There also are contact areas which in the effective range of angular rotation of the clutch disc move essentially from one friction area at least partly to another friction area.

Abstract: A clutch disc for a motor vehicle clutch, the clutch disc having an idle suspension system and a load suspension system. The idle springs of the idle suspension system are located in the hub disc and are actuated by means of a control plate. The control plate includes axially bent control tabs which engage the idle springs of the idle suspension system, whereby the width of the idle springs can be approximately equal to the thickness of the hub disc.

Abstract: The present invention relates to a clutch disc in which the output part is composed of two elements which on one hand run alongside a hub disc for an idle device, and on the other hand are engaged by means of radial arms in apertures of an intermediate part, to apply pressure to two sets of springs which are located in those apertures and connected in series. The two-piece output part can thereby be prefabricated with the intermediate part and the hub disc for the idle damper as a separate unit.
