Abstract
A pulley decoupler for an accessory drive comprises input and output parts. The output part and the input part are rotatable about a common axis of rotation and are rotatable to a limited extent relative to one another. A centrifugal pendulum device is provided for damping torsional vibrations with a centrifugal pendulum flange that can be rotated about the axis of rotation and has at least one pendulum mass displaceable under centrifugal force relative to the centrifugal pendulum flange. The at least one pendulum mass is acted on by a friction force generated by a first friction device having a first spring and at least one first friction element.
