Abstract
A friction device for a torsional vibration damper includes an axis of rotation, an input side with a first disc and a second disc, and an output side between the first disc and the second disc and rotatable relative to the input side. The output side has a first friction disc, a second friction disc, and a spring element between the first friction disc and the second friction disc. The spring element has first, second and third contact regions. At a first angle of rotation between the input side and the output side, an axial contact force between the first friction disc and the second friction disc is transmittable via the first contact region and the third contact region. At a second angle of rotation, different than the first angle of rotation, the axial contact force is transmittable via the second contact region and the third contact region.
