Abstract

A device for damping rotary oscillations in a drive train with a freewheel clutch (27) located between a pulley (25) and a rotor hub (26) is provided. The hub (26) is connected to an input shaft of an auxiliary unit, and the pulley (25) is connected to a crankshaft via a traction means, and the freewheel clutch (27) has an inner ring (34), which surrounds the hub (26) while being fixed thereto, and includes an outer ring (35), which surrounds the inner ring (34) with radial play and which is fixed to the pulley (25). At least one locking element (36) that is actuated by centrifugal force is provided in the inner ring (34), and at least one locking receptacle (37) is provided in the outer ring (35).
