Abstract: The disclosure relates to a disk (38) for a disk clutch (26) comprising an annular base element (76) which has a toothing (78) with multiple teeth (80) for achieving a rotary driving engagement with a disk carrier (34), wherein the base element (76) has at least one hardened region (96) in which the base element (76) is designed as harder than in the tooth flank regions (98, 100) of the teeth (80). In addition, the disclosure relates to a disk clutch (26) with such a disk (38), a double clutch device (2) with such a disk clutch (26), and a method for producing such a disk (38).

Abstract: A torsional vibration damper includes a drive-side primary element having at least one primary dog, an output-side secondary element having at least one secondary dog, and at least one spring device between the primary and secondary dogs for spring-elastic coupling of the primary element to the secondary element and including a plurality of spring elements. A separator sheet includes a ring element. At least one sliding block extends from the ring element between adjacent spring elements and is arranged circumferentially about the spring elements. The primary element has also an inner part having an external toothing, an outer part on which the primary dog is arranged and having an internal toothing engaging into the external toothing, and at least one damping part arranged between the external and internal toothing for vibration damping between the inner and outer parts.

Abstract: A torsional vibration damper includes a primary element with at least one primary driver, a secondary element with at least one secondary driver, at least one spring device between the primary and secondary drivers for resiliently elastic coupling of the primary and secondary elements, and at least one end block arranged on an end side of the spring device. The primary element is rotatable relative to the secondary element from a neutral position into a first position, in which the primary driver is supported only on the spring device, and from the first position onward into a second position, in which the primary driver is supported on the spring device and on the end block. In the first and second positions of the primary element, torque of the torsional vibration damper can be transmitted exclusively directly between the primary driver and spring device.

Abstract: A torsional vibration damper includes at least one spring element and a sliding block. The sliding block includes a first surface section that operatively faces an adjacent spring element, is harder than another surface section of the sliding block, has first and/or second supporting surfaces for radial support of the spring element, and has first and/or second supporting surfaces for axial support of the spring element. A second surface section has a sliding surface for sliding support of the sliding block, and a basic body includes plastic. The first and/or second surface section(s) is/are formed by at least one first insert that is harder than the plastic. The first surface section is formed by at least two elongate second inserts that are spaced apart from one another and projected and on which the spring element can be supported in a centering manner in a radial direction.

Abstract: A torsional vibration damper employs a sliding block of the present invention. The torsional vibration damper includes at least one spring element, and the sliding block has a first surface section that operatively faces an adjacent spring element and is harder than another surface section of the sliding block. The torsional-vibration damper employs a separator sheet of the present invention that includes the sliding block, and a method of the present invention produces the sliding block.

Abstract: A torsional vibration damper includes a drive-side primary element having at least one primary dog, an output-side secondary element having at least one secondary dog, and at least one spring device between the primary and secondary dogs for spring-elastic coupling of the primary element to -the secondary element. The primary element has also an inner part and an outer part, on which the primary dog is arranged, and at least one damping part for vibration damping between the inner and outer parts.
