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: The invention relates to a coupling arrangement comprising a component (6) fixed to a housing, a piston (2) that is located rotatably about an axis of rotation (?) relative to the component (6) fixed to a housing, a rotatable component (1) designed as a component mounted rotatably about the axis of rotation (?) relative to the component fixed to a housing and having a chamber (8) in the front region of the piston (2), a line arrangement (4) forming a communication line through the component (6) fixed to a housing and the rotatable component (1) to the chamber (8) for a pressure medium, and a rotary feedthrough seal (3) sealing the line arrangement (4) between the component (6) fixed to a housing and the rotatable component (1), wherein a radial inner distance (ri) and/or a radial outer distance (ra) of the piston (2) from the axis of rotation (?) is less than a radial seal distance (r0) of the rotary feedthrough seal (3).

Abstract: The invention relates to a clutch arrangement having a component which is fixed to a housing, having a piston which is arranged so as to be rotatable about a rotational axis relative to the component which is fixed to the housing, having a hollow cylindrical or annular chamber which surrounds the piston at its end-side region, and having a line arrangement which, for conducting a pressure medium for actuating the piston, leads to the chamber through the component which is fixed to the housing, wherein the chamber is formed as a constituent part of the component which is fixed to the housing and which forms a cylinder, and wherein the piston is arranged in the chamber so as to be rotatable.

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.

Abstract: A dual clutch transmission having radially nested clutches including an outer clutch having first inner and outer clutch disks that are interleaved between each other where the first outer clutch disks are operatively mounted to a first outer support carrier. The transmission also includes an inner clutch having second inner and outer clutch disks operatively interleaved between each other and operatively mounted to a second inner support carrier. A common disk carrier has a common clutch disk carrier that operatively supports the first inner clutch disks of the outer clutch and the second outer clutch disks of the inner clutch.
