Title (EN) FLEXIBLE FLYWHEEL, PARTICULARLY FOR A MOTOR VEHICLE
(FR) VOLANT FLEXIBLE, EN PARTICULIER DE VEHICULE AUTOMOBILE
Abstract:
(EN) The invention relates to a flexible flywheel, particularly for a motor vehicle, comprising at least two stacked flexible discs (9, 10, 11) each comprising at least two parallel planar parts (15, 16) which are axially offset (D1) and joined together by a curved part (18), the curved parts (18) of the discs (9, 10, 11) being more or less nested one inside the other or inside one another, characterized in that, in at least one region adjacent to a curved part, the discs (9, 10, 11) are separated from one another so as to form a space (23) to make axial deformation of the discs (9, 10, 11) easier.
(FR) L'invention concerne un volant flexible, en particulier de véhicule automobile, comprenant au moins deux disques flexibles empilés (9, 10, 11), comprenant chacun au moins deux parties planes parallèles (15, 16), décalées axialement (D1) et raccordées l'une à l'autre par une partie cambrée (18), les parties cambrées (18) des disques (9, 10, 11) étant sensiblement emboîtées l'une dans l'autre ou les unes dans les autres, caractérisé en ce que, dans au moins une zone adjacente à une partie cambrée, les disques (9, 10, 11) sont écartés les uns des autres, de manière à former un espace (23) facilitant la déformation axiale des disques (9, 10, 11).
