Abstract: A freewheel arrangement having a freewheel, which comprises an inner ring, an outer ring rotatable in a first direction of rotation relative to the inner ring, and clamping elements between the inner ring and the outer ring, which prevent a rotation of the outer ring relative to the inner ring in a second direction of rotation. The outer ring and the inner ring and the clamping elements may be formed as a stamped sheet metal part.

Abstract: A method for producing a pattern of depressions in the friction surface of a friction component for a frictionally operating device, preferably a multiplate clutch or multiplate brake. After the preparation of the friction component, the pattern of depressions is produced by nontraditional material removal, removal of material preferably being accomplished in a contactless manner, particularly preferably with the aid of a laser beam.

Abstract: The invention relates to a friction element, in particular a clutch disk or brake disk, having: a disk-shaped lining carrier which supports or has at least one friction lining and has a central opening, and at least one hub part with a central receiving opening, which is formed with a hub toothing, for receiving a shaft which is formed with a shaft toothing, wherein the hub part and the lining carrier are arranged adjacent to one another so as to rotate together with the shaft, and wherein the central opening of the lining carrier is embodied as a shaft receiving opening with a lining carrier toothing for engaging into the shaft toothing of the shaft.

Abstract: A torsional-vibration damper rotatably supported for translating torque between a prime mover and the input of a transmission that includes a primary element operatively connected for rotation with the power take off of a prime mover and a secondary element operatively connected for rotation with the input to a transmission. A spring mechanism is operatively disposed between the primary element and the secondary element that is adapted to operatively couple the primary element to the secondary element in a damped torque translational relationship. The torsional-vibration damper also includes a friction device having a plurality of friction blocks that are each operatively supported between the primary element and the secondary element such that the friction blocks provide frictional contact between the primary element and the secondary element.

Abstract: A torsional-vibration damper includes a primary element operatively connected for rotation with a prime mover and a secondary element operatively connected with the input to a transmission. A spring mechanism is operatively disposed between and adapted to control the primary element and the secondary element in damped torque translational relationship. The torsional-vibration damper also includes a friction device having a plurality of fiction blocks that frictionally join the primary element with the secondary element. The secondary element includes an output-side member having a first axial ridge and a drive-side member having a second axial ridge. The output-side member and the drive-side member operatively encompass the primary element and the first axial ridge overlaps the second axial ridge. The first and the second axial ridges thereby cooperate to provide a double layer of radial support for the spring mechanism.

Abstract: A torsion-vibration absorber for use with a motor vehicle includes a transmission element at a driving end and a transmission element at a driven end adapted to be rotary deflected around an axis to the transmission element at the driving end. At least one compression spring connects the transmission element at the driven end with the transmission element at the driving end. At least one reinforcing component is encompassed by at least a portion of the at least one compression spring and includes a securing device to substantially limit displacement of the at least one reinforcing component in relation to the at least one compression spring.

Abstract: The invention concerns a vibration damping device (2). This includes at least two elements—a primary element (3.1) and a secondary element (3.2), which are limited in movement in relation to each other. The primary element (3.1) and the secondary element (3.2) can be coupled together using a spring coupling. The means to implement spring coupling include at least one spring device (4.1, 4.N). Based on the invention, there is at least one adjustable clutch device (15, 15′), including at least two elements (16, 17; 16′, 17′) rubbing against each other, which bring primary and secondary elements (3.1, 3.2) into friction contact. In addition, there is a power generator or force producing device (39) to produce a controllable friction contact for the elements rubbing against each other (16, 17; 16′, 17′).

Abstract: A disk assembly having a circular friction lining mounted on one or both sides of a support member. An oil channel extends from the outer edge of the friction lining to the inner edge. The oil channel includes an enlarged middle oil reservoir section extending completely through the friction lining. An inlet section and an outlet section of the oil channel are in communication with the reservoir section and are narrow grooves which are embossed in the friction lining during bonding of the friction lining.
