Abstract: A coupling arrangement is provided with a vibration reduction device and with a clutch device. The vibration reduction device has at least one torsional vibration damper, an input connected to a drive, and an output connected to the clutch device by which a connection between the vibration reduction device and a driven end is at least substantially produced in a first operating state, and this connection is at least substantially cancelled in a second operating state. The vibration reduction device has a mass damper system that cooperates with the torsional vibration damper and is connected to the output of the vibration reduction device.

Abstract: A torsional vibration damper (70) with a damping device which has an input (67) and an output (72) which is operatively connected to a driven side (73). The output is connected to a mass damper system (1) and also to a mass arrangement (100). One of the two subassemblies—i.e., mass damper system (1) and mass arrangement (100)—which are connected to the output (72) of the damping device (70) engages at the respective other subassembly comprising mass damper system or mass arrangement which is in turn connected to the output by a connection arrangement (77).

Abstract: A torsional vibration damper has an input, an output and an intermediate mass arranged therebetween, a first plurality of spring elements coupled between the input and the intermediate mass that form a first stage, a second plurality of spring elements coupled between the intermediate mass and the output that form a second stage of the torsional vibration damper, at least one damper mass to damp the vibration component of the rotational movement. The first stage of the torsional vibration damper has a progressive first characteristic with at least one transition point. The second stage of the torsional vibration damper has a progressive, second characteristic with at least one transition point. All of the transition points of the first characteristic and the second characteristic are spaced apart from one another with respect to torque.

Abstract: An inner housing hub is arranged in a gas turbine about a gas turbine shaft and is formed as a component of an inner housing used to deflect hot gases exiting combustion chambers towards a turbine inlet region arranged in the direction of the gas turbine shaft. The inner housing hub includes at least one substantially cylinder casing-shaped securing portion having a cylinder casing-shaped main part, which has a hot side facing a hot gas path and a cold side facing away from the hot gas path. At least one web-shaped protrusion extends along the cold side and is arranged on the cold side on the main part in order to secure the inner housing hub. The web-shaped protrusion is made of a first material and the main part is made of a second material, the first material having a greater thermal expansion coefficient than the second material.

Abstract: The present invention relates to a device (01, 22) for use in the interior of a vehicle, comprising a first and a second carrier element (02, 23, 03, 24) and a connecting linear guide, wherein the first carrier element (02, 23) features two linearly extending first guiding surfaces (06, 07, 27, 28) and the second carrier element (03, 24) features two first abutment surfaces (12, 13, 33, 34), wherein the carrier elements (02, 23, 03, 24) are longitudinally displaceable relative to each other when the abutment surfaces (12, 13, 33, 34) slide along the guiding surfaces (06, 07, 27, 28), and wherein the linear guide produces a clamping effect which prevents self-actuated displacement of a carrier element (02, 23, 03, 24) due to vehicle movements, wherein the linear guide further features a second guiding surface (08, 29) being associated with the first carrier element (02, 23) and features a second abutment surface (14, 35) being associated with the second carrier element (03, 24), wherein, when the first and the
