ABSTRACT:
A torsion damping device comprises two coaxial masses and a friction device, which acts between the two coaxial masses and surrounds a central hub of the first mass. The friction device is a unitary assembly which comprises at least one element of elastic material, with a friction ring secured over at least one of its faces, for contact with a first friction surface carried by one of the coaxial masses. This unitary assembly is interposed, so as to be gripped radially, between the first friction surface and a second surface fixed to the other mass. The invention is applicable to torsion dampers for motor vehicles.
