Abstract

L'invention concerne un dispositif permettant d'atténuer les vibrations dans un véhicule à moteur, lequel dispositif est particulièrement conçu pour atténuer les vibrations de différentes fréquences dans l'arbre de transmission du véhicule. Ce dispositif est constitué d'un corps en caoutchouc (1) se présentant sous la forme d'une bague, dans lequel est insérée une pièce métallique annulaire (2). Ledit corps en caoutchouc (1) est pourvu de nervures intérieures (5) qui lui permettent d'être couplé à l'axe de l'arbre de transmission, et il peut éventuellement être prolongé par un col axial (6) pour permettre le raccordement d'un collier qui complète la fixation dudit axe. Le mode de réalisation se caractérise en ce que la bague formée par la combinaison du corps en caoutchouc (1) et de la pièce métallique (2) présente une section discontinue le long de son périmètre et dans laquelle sont définis quatre secteurs d'amplitude angulaire identique présentant des sections deux par deux identiques et disposées alternativement, lesquelles définissent différentes sections créant les différentes fréquences de résonance.
