Abstract
A damped flywheel (10) of the type comprising a first rotating element (12) and a second rotating element (14), which are coaxial and which have the general form of parallel plates (20, 26), and which define between them an annular housing (30) which receives a resilient damping device (32), together with an annular space which receives a friction damping device (58), and of the type comprising two coaxial sealing rings (56A, 56B), in which the friction damping device (58) comprises a part (62) which is driven in rotation by the second rotating element (14) through a head (68) of a member (66) that fastens one (56A) of the sealing rings (56A, 56B) on an annular disc (42) of the second rotating element (14).
