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 a 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.
