Abstract

L'invention concerne un dispositif assouplisseur et stabilisateur destiné à être disposé entre deux éléments (A, B) présentant une section circulaire, un élément étant susceptible de créer des vibrations et l'autre étant susceptible de vibrer sous l'influence du premier, le dispositif comprenant un ensemble de N bloc(s) (B1,..., BN) de torsion, chaque bloc comprenant une barre (10, 10') de torsion, un levier central (11) disposé au centre de la barre (10), un premier levier (12) situé à une première extrémité de la barre et un second levier (13) situé à une seconde extrémité de la barre.The invention relates to a softener and stabilizer device intended to be disposed between two elements (A, B) having a circular section, one element being capable of creating vibrations and the other being capable of vibrating under the influence of the first, the device comprising a set of N torsion block (B1, ..., BN), each block comprising a torsion bar (10, 10 '), a central lever (11) disposed in the center of the bar (10 ), a first lever (12) located at a first end of the bar and a second lever (13) located at a second end of the bar.
