Abstract

A flywheel with two centrifugal masses has a secondary centrifugal mass assembled from two individual parts, wherein the first part is actively connected to a torsion damping device, and the second part has a friction surface for a friction clutch. To increase the useful life of the flywheel system, the two parts of the secondary centrifugal mass are held at a distance from one another, and are connected to one another in their radially inner area essentially only by means of axially projecting spacer elements, which spacer elements are distributed circumferentially, and by means of rivets or screws. The rear side of the second part of the secondary centrifugal mass can thus be air cooled by the system of air cooling passages.
