Title (EN) TORSIONAL VIBRATION DAMPERS
(FR) AMORTISSEURS DE VIBRATIONS DE TORSION
Abstract:
(EN) Torsional vibration dampers having a dual spring-dashpot system are disclosed that result in a lightweight hub and a lightweight inertia ring, which is concentric about the hub. The hub has a two-piece construction: a central hub defining an innermost sleeve that defines a bore for receiving a shaft; and a monolithic, generally-annular spoke defining an outermost ring concentric about and spaced radially outward from the central hub portion. A first elastomer member, which acts as a primary spring to damp torsional vibrations, is positioned concentrically against an inner surface or an outer surface of the outermost ring of the hub with the inertia ring concentrically positioned against the first elastomer member. A second elastomer member is positioned between and operatively couples the central hub to the annular spoke, thereby attributing a flexibility to the hub.
(FR) L'invention concerne des amortisseurs de vibrations de torsion ayant un système d'amortisseur à double ressort, lesquels amortisseurs produisent en résultat un moyeu de faible poids et une bague d'inertie de faible poids, qui est concentrique autour du moyeu. Le moyeu a une construction en deux pièces : un moyeu central définissant un manchon interne qui définit un perçage pour recevoir un arbre ; et un rayon monolithique globalement annulaire définissant une bague externe concentrique autour de la partie de moyeu centrale et espacée radialement vers l'extérieur vis-à-vis de cette dernière. Un premier élément élastomère, qui joue le rôle de ressort primaire afin d'amortir des vibrations de torsion, est positionné de façon concentrique contre une surface interne ou une surface externe de la bague externe du moyeu, avec la bague d'inertie positionnée de façon concentrique contre le premier élément élastomère. Un second élément élastomère est positionné entre le moyeu central et le rayon annulaire, et relie ces derniers de façon fonctionnelle, de façon à communiquer ainsi une souplesse au moyeu.
