Abstract: A clutch having a narrow housing and including a disengagement unit for a clutch pressure plate with a device for applying an essentially radially directed force onto the pressure plate, and wherein the device is driven in a radial direction.

Abstract: A disengaging device for a clutch with an energy store that releases energy upon disengagement and stores energy upon re-engagement. This device is compactly constructed and allows force to be advantageously reinforced. Mechanisms are used to increase the energy in the energy store in relation to the force arising in the disengaging device. In addition, the invention further comprises mechanisms to divert force, or a roller that is guided via a guide surface and a bevel that interacts with the energy store. Furthermore, a unit of the energy store and a drive are arranged so that they receive forces parallel to each other.

Abstract: A clutch having narrow housing and including a disengagement unit for a clutch pressure plate with a device for applying an essentially radially directed force onto the pressure plate, and wherein the device is driven in a radial direction.

Abstract: A torsional vibration damper includes two structural units rotatable relative to one another and linked to each other by a spring arrangement which includes at least one thrust piston. At certain angles of rotation between both structural units, the flow of force between the thrust piston of the spring arrangement and at least the secondary structural unit is realized via an outer surface area that engages the thrust piston, wherein the outer surface area is formed on a separate third structural unit which is resiliently mounted relative to the secondary structural unit.

Abstract: A clutch with an axially-effective clutch pressure plate can be made particularly narrow if an actuating element for the clutch pressure plate features a device which is essentially radially driven. This design is for the application of an essentially axially driven force on the clutch pressure plate. Likewise, a motor vehicle clutch can be designed to be narrow if the disengagement unit of the motor vehicle clutch features a disk spring which acts on a clutch pressure plate, and a central disengagement element which is connected with the disk spring. In this case, the disk spring features an area bent in the axial direction, on which a plunger engages, capable of being actuated by the central disengagement element.

Abstract: A mechanical torsional vibration damper includes a primary part and a secondary part which are connected to one another by a spring and damping system of tangential compression springs and thrust plungers acting on contact surfaces on the primary part and the secondary part, with an additional damping unit being provided between the primary part and the secondary part.

Abstract: A torsional oscillation damper, in particular a friction disk damper, includes a primary part, a secondary part rotatable with respect to the primary part, an intermediate disk disposed between the primary part and the secondary part. Acting upon the intermediate disk are tangential compression springs and pre-damping springs, with the tangential compression springs disposed tangentially between the secondary part and the intermediate disk, and the pre-damping springs disposed between the primary part and the intermediate disk.

Abstract: A device for changing the flow rate of a liquid damping medium is a torsional vibration damper. This damper has a rotating cylindrical damper housing, connected between a drive shaft and a power takeoff shaft. Pinions are surface-mounted in a planetary fashion without axle journals between the axial faceplates of a gear pump in recesses in the pump interior. The pinions are engaged with a central gear seated on the power takeoff shaft or on drive shaft, which form gear pumps for closed circulation of the damping medium.
