Abstract

A torsional vibration damper is equipped with a drive-side transmission element and an output-side transmission element deflectable relative thereto. A friction device is connected between the transmission elements. The friction device has a friction element with at least two different friction areas. The friction element is arranged in a circumferential opening having circumferential ends in one of the transmission elements. As long as the friction element is movable within the circumferential opening relative to the ends of the circumferential opening, only a first friction area of the friction element is active. When the friction element contacts one of the circumferential ends of the circumferential opening, only a second friction area of the friction element is active.
