Abstract
A damped flywheel, in particular for a motor vehicle in conjunction with the clutch of the vehicle, comprises two coaxial masses which are mounted for rotational displacement of one with respect to the other. One of the masses includes a centring nose which projects axially and penetrates into a central opening of the other mass. An amorphous diamond carbon coating is provided between the centring nose and the central opening, so that one of the rotating masses is mounted on the other through this coating.
