Abstract
A double damped flywheel for a motor vehicle comprises a first mass having a central hub, a second mass, a torsion damper, and a friction device working axially between the first mass and the second mass and having at least one friction ring in contact with a friction surface. The friction ring and the associated friction surface are carried by a support cage which is fitted on a local portion, having an increased radius, of the central hub, this cage being located axially by a transverse thrust plate of the first mass, so that the cage is located between this thrust plate and the anti-friction bearing by which the second mass is mounted on the first mass.
