Abstract

A torsional vibration damper with a friction device. The friction device is formed on at least one friction surface on two contra-rotationally and oppositely disposed disc parts that are in frictional contact with one another. In order to propose how to determine the initial stressing effect of the frictional action independently of external support of the disc parts, the frictional surfaces are pressurized against one another by means of at least one spring element.
