Abstract: A torsional vibration damper has two mutually pivoted masses and a friction device that is active between the masses. This friction device can include a first friction device that is a spring friction device and an auxiliary friction device comprising at least one entraining wedge. The entraining wedge can function as dual wedge having at least two frictional surfaces for contacting at least one of the two mutually pivoted masses. There can also be at least one additional entraining wedge disposed parallel to the at least one entraining wedge inside of a chamber formed between the two mutually pivoted masses. The friction device and the auxiliary friction device frictionally couple the two mutually pivoted masses together.

Abstract: In order to adapt the damping behavior at a wider range in a process for damping torsional vibrations and in a torsional vibration damper, the length of an elastic element can be changed in dependence on a relative angle between two rotational subassemblies, with the degree of change in length being variable in dependence on the relative angle. Furthermore, a thrust piston of a coupling element, which couples the two subassemblies, can be displaced in dependence on the relative angle, relative to a first one of the two subassemblies.

Abstract: A simplified torsion vibration damper having a primary plate and a secondary plate wherein the primary plate is manufactured from a primary plate which transfers a torque onto the secondary plate and the additional rim. The torque is transferred through springs to this secondary plate and additional rim which is connected via angled areas to the primary plate. A starter gear rim can be provided on the additional rim. In addition, a generating element plate with drill holes can be fitted at the primary plate and the additional mass which serves as a location-dependant motor control unit. The manufacturing process can be simplified even further through the proper arrangement of the secondary plate and the bearing sleeve.

Abstract: A compact friction plate damper having a primary plate and a secondary plate, which interacts by means of a friction element. A speed-dependent control device is provided for the friction, wherein the friction device has a contact arrangement upon which force is to be exerted essentially radially. The friction control device comprises a spring element, which takes effect with rotational speed-dependent force on the contract arrangement in an essentially radial manner. In addition to this, the friction device interacts by friction with the secondary plate, and is mounted so as to be rotationally movable in relation to the primary plate by at least a small angle. Thus the friction control comprises a rotational speed-dependent coupling element between the primary plate and the friction device.
