Abstract: A friction clutch for a motor vehicle is embodied with a centrifugal mass device, which has at least one mass-bearing compensating system. At least one component of the centrifugal mass device is equipped, to form the compensating system, with at least one chamber that holds, to a predetermined degree of fullness, a fluid medium, whose position in the chamber changes when a torsional vibration occurs. The effect resulting from this position change depends on the density and viscosity of the medium, on the one hand, and, on the other hand, on the arrangement of the chamber, which determines the vibrational behavior of the medium, the shape of the chamber, which determines the movement resistance, and its degree of fullness.

Abstract: A motor vehicle friction clutch with automatic wear compensation has a wear compensation element, which wear compensation element can rotate around a clutch axis. The friction clutch also includes an adjustment device, which adjustment device includes a worm rotatably mounted on a carrier. The wear compensation element is a worm gear that meshes with the worm to advance the wear compensation element along the clutch axis to compensate for wear. Axial play in the direction of the clutch axis is provided between the worm gear and the worm to detect wear of the friction linings.

Abstract: 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.

Radially acting stops on the hub can be provided peripherally between the individual spring tongues to limit the spring travel.

Abstract: 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).

Abstract: 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 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.

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.

Abstract: 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.

Abstract: 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.

Abstract: Described in a suspension conveyor system suitable for the use of conveyance units having two travelling rollers interconnected by an open yoke. The suspension conveyor system is universally applicable and capable of optimum adaptation to operating and space conditions in a given plant. To this purpose the system comprises changeover means selectively operable to tilt a conveyance unit to a left or right laterally suspended position or a center-suspended position to thereby permit for instance the radii of curved rail sections to be considerably shortened and particularly achieve a less complicated construction of required switches. In a preferred embodiment the switch is formed as an integral shaped member, so that the continuity of the rail circuit has not to be interrupted for guiding a conveyance unit onto selected branch rails.

Abstract: The torsional vibration damper suitable for the clutch disc of a motor vehicle friction clutch comprises an idling damper, the springs of which are retained in recesses of a toothing which couple the hub of the damper with a disc part, with limited play in rotation. The end faces of the spring lie for the one part on stop edges of the disc part and for the other part on stop edges of two retaining discs which annularly enclose the hub. The retaining discs are coupled non-rotatably, by axial bent-out portions, with a hub disc of the hub, and for assembly are pushed axially on to the hub. The retaining discs can be produced simply and fitted without problem. FIG. 1.
