ABSTRACT:
A device for damping torsional vibrations in a drive train of a traction drive connecting an internal combustion piston engine and an auxiliary unit, comprising an overrunning clutch (5,30,48) arranged between a driving pulley (2,25,42) and an input shaft (1) of the auxiliary unit or between a crankshaft and a driven pulley of the internal combustion piston engine, characterized in that the overrunning clutch (5,30,48) comprises an inner or outer ring (8,9,28,29,50) made of sheet metal without chip removal on which locking ramps cooperating with locking rollers (10,30a,48a) are formed, and the inner or outer ring (8,9,28,29,50) extends at least on one side beyond a region of the locking ramps to form a raceway for a rolling bearing (6,7,31,32,45,49).
