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.

Coupling arrangement having a vibration reduction device and having a coupler device

A clutch device has a friction transmission element which has a base with at least one friction surface, at least one control element for acting on a damping device, and at least one radial support which cooperates with a stop and has a plurality of lugs which extend at least substantially radially in direction toward the stop and which are at least substantially brought closer to the stop up to a gap before the stop when the friction transmission element is stationary, while, at speed, at least a portion of the lugs comes in contact with the stop. The lugs are connected to the base via a bend which causes an axial offset with respect to the base, the bend allows a displacement of the lugs in direction toward the energy accumulators, and the lugs are completely covered by the stop in an axial extension direction.

Clutch device with a friction transmission element

A vibration damping having a first torsional vibration damper couplable to a drive member with a first secondary side rotatable with respect to the first primary side against a return action of a first damper element arrangement, a second torsional vibration damper with a second primary side connected to the first secondary side and with a second secondary side rotatable with respect to the second primary side against the return action of a second damper element arrangement and couplable to an output member, and a deflection mass pendulum arrangement having at least one deflection mass. The first damper element arrangement has a plurality of first damper element units acting parallel to one another and/or the second damper element arrangement has a plurality of second damper element units acting parallel to one another.

Vibration damper assembly, in particular for the power train of a vehicle

A torsional vibration damper arrangement including a torsional vibration damper with a primary side and a secondary side rotatable with respect to the primary side around an axis of rotation against the action of a damper spring arrangement. One side of the primary side and secondary side includes two cover disk elements and a central disk element arranged between the cover disk elements. The cover disk elements are connected to one another by first connection elements radially inside the damper spring arrangement so as to be fixed axially and so as to transmit torque. The cover disk elements are connected to one another by second connection elements in such a way that they are prevented from moving axially away from one another. No torque can be transmitted between the cover disk elements by the second connection elements.

Torsional vibration damping arrangement, particularly for the power train of a vehicle

A method for riveting two structural component parts arranged with their inner sides facing one another and with their outer sides facing away from one another at a distance from one another by at least one spacer rivet element. Positioning the at least one spacer rivet element at the two structural component parts such that rivet element end areas extend through rivet openings provided in the structural component parts to be associated with the rivet element end areas. Supporting a rivet element end area at the outer side of one of the structural component parts. Supporting the other of the structural component parts at its inner side. Applying a riveting force to the other rivet element end area to deform at least one rivet element end area and to form a rivet head.

Method for riveting two cover plate elements of a torsional vibration damper arrangement

A torsional vibration damper arrangement such that an excessive radially outward flexing of spring units is effectively prevented while torsional vibrations occurring at low torques are nevertheless sensitively damped and the corresponding spring unit is protected against overloading at the same time.
