A vibration damper that damp vibrations transmitted between a drive unit and a support body. The vibration damper comprises: an elastic member interposed between the drive unit and the support body; a rotor supported by the drive unit or the support body; and a vibration translating mechanism that rotates the rotor and reciprocates the rotor between the drive unit and the support body, in response to the vibrations acting in a vibrating direction to isolate the drive unit and the support body away from each other and bring the drive unit and the support body closer together.

A rotary damper device includes a drive component and a rotary damper upstream of the drive component. The drive component has an input gear with an external toothing and axially open cut-outs. The rotary damper has an annular carrier, a spring element arranged in the annular carrier, an output gear with an internal toothing meshed with the external toothing, and a clamping ring with a plurality of axially extending fingers engaged in the axially open cut-outs to clamp the output gear against the input gear.

A converter unit having a damping system and having a torque transfer unit for connecting an input shaft separably to an output shaft, wherein the torque transfer unit has a co-rotating housing and the damping system can be installed centered and detachably on the housing is provided. With the converter unit proposed here standard components can be used, which are compact and easily installable.

A clutch arrangement is provided with a mass damper system having a damper mass carrier and damper masses deflectable relative to the damper mass carrier. The clutch arrangement has a housing having at least two housing parts permanently connected to one another by a fixed connection, at least one housing parts has a cutout for at least one projection of the other housing part. The housing parts are assembled while receiving the damper mass carrier between an axial stop of the cutout of the one housing part and the projection of the other housing part. The housing parts are loaded over the course of producing the fixed connection by a clamping mechanism which acts on the housing parts in direction away from one another and operative axially between one of the housing parts and the damper mass carrier axially supported at the other respective housing part.

An exemplary embodiment of the present invention provides a dual clutch device provided in a housing coupled, at one side, to a transmission and coupled, at the other side thereof, to an engine, the dual clutch device including a motor including a stator and a rotor received in a cover, dual clutches provided close to the transmission based on the motor and connected to the rotor, an engine clutch provided close to the engine based on the motor and connected to the rotor, and a damper provided in the housing and connected to the engine clutch through a damper spline.

A torsional vibration damper comprises an input side and an output side which are arranged rotatably around an axis of rotation, an intermediate plate, and two elastic elements which are arranged on different circumferences around the axis of rotation, where the first elastic element is set up to transmit a power from the input side to the intermediate plate and the second elastic element is set up to transmit a power from the intermediate plate to the output side. Furthermore, the torsional vibration damper includes a single-piece retainer to support the first elastic element on a radially outer surface, while the retainer includes a contact element for engaging with one end of the first elastic element.
