Title (EN) TORSIONAL VIBRATION DAMPERS HAVING A HUB WITH SPOKES ACTING AS A SECOND SPRING IN SERIES WITH AN ELASTOMERIC MEMBER
(FR) AMORTISSEURS DE VIBRATIONS DE TORSION COMPRENANT UN MOYEU AVEC DES RAYONS AGISSANT COMME UN SECOND RESSORT EN SÉRIE AVEC UN ÉLÉMENT ÉLASTOMÈRE
Abstract:
(EN) Torsional vibration dampers for rotating shafts are disclosed that have a hub or a hub portion of a pulley-hub monolithic body that has an innermost sleeve defining a bore, an outermost ring concentric with and spaced radially outward from the innermost sleeve, and a plurality of spokes connecting the innermost sleeve to the outermost ring that each have torsional flexibility to act as a first spring to attenuate torsional vibrations. The dampers include an elastomeric member positioned concentrically against the outermost ring or the innermost sleeve of the hub, where the elastomeric member acts as a second spring to attenuate torsional vibrations, and an inertia member positioned concentrically against the elastomeric member, which places the first spring and second spring in series. The dampers may be crankshaft, driveline, or direct drive dampers, and the equivalent spring rate for the first and second springs is governed by the elastomeric member.
(FR) L'invention concerne des amortisseurs de vibrations de torsion pour faire tourner des arbres, comprenant un moyeu ou une partie de moyeu d'un corps monolithique de type moyeu-poulie qui présente un manchon le plus à l'intérieur définissant un alésage, un anneau le plus à l'extérieur concentrique avec le manchon le plus à l'intérieur et espacé radialement vers l'extérieur depuis celui-ci et une pluralité de rayons reliant le manchon le plus à l'intérieur à l'anneau le plus à l'extérieur qui présentent chacun une flexibilité de torsion afin d'agir comme un premier ressort pour atténuer les vibrations de torsion. Les amortisseurs comprennent un élément élastomère positionné de façon concentrique contre l'anneau le plus à l'extérieur ou le manchon le plus à l'intérieur du moyeu, l'élément élastomère agissant comme un second ressort pour atténuer les vibrations de torsion, et un élément d'inertie positionné de façon concentrique contre l'élément élastomère, qui positionne le premier ressort et le second ressort en série. Les amortisseurs peuvent être des amortisseurs pour vilebrequin, transmission ou entraînement direct et la raideur du ressort équivalente pour les premier et second ressorts est gouvernée par l'élément élastomère.
