Claim 18:
19. A pulley decoupler for an accessory drive, comprising:
an input part;
an output part, the output part and the input part being rotatable about a common axis of rotation and being rotatable to a limited extent relative to one another; and
a centrifugal pendulum device for damping torsional vibrations with a centrifugal pendulum flange which can be rotated about the axis of rotation and which has at least one pendulum mass which is displaceable under centrifugal force relative to the centrifugal pendulum flange, wherein 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;
wherein the centrifugal pendulum device is at least partially covered by a first cover cap which is fastened to a pulley of the output part;
wherein the at least one pendulum mass is arranged in a centrifugal pendulum space of the centrifugal pendulum device, wherein the centrifugal pendulum space is at least partially closed by a second cover cap;
wherein the second cover cap is connected to a second friction device, so that the second cover cap generates an axial force on the pulley decoupler.
