Abstract
The invention relates to a flexible flywheel (), in particular for a motor vehicle, comprising at least two stacked flexible discs (). The inner peripheries () of the flexible discs are secured to a drive shaft, and the outer peripheries () of are secured to an inertia mass (). Each flexible disc () includes at least two parallel flat parts (), which are offset axially (D, D) and connected to one another by a curved part (). The curved parts () of the discs () are substantially nested one inside the other, characterized in that, in at least one region adjacent to a curved part, the discs () are spaced one from the other so as to form a space () which facilitates the axial deformation of the discs ().
