ELASTIC COUNTER SHEET WITH INTEGRATED HYDRO-MECHANICAL RESONATOR, PARTICULARLY FOR SUSPENSION OF A TRANSMISSION BOX ON A rotorcraft and suspension device comprising application

摘要

P In this elastic strut incorporating a hydro-mechanical resonator with mass-spring system, of the type with hydraulic amplification of the displacement of the beating mass 7, said mass mounted between two opposing return springs constitutes a double-sided hollow piston slidably mounted on two coaxially opposite cylinders 6 in a closed chamber filled with a liquid 10 in an internal tubular element 1 disposed in an external tubular element 2 with which it delimits, at each end, a chamber 18, 26 filled with liquid, in which opens one of said cylinders 6, said elements 1, 2 constituting the body of the strut are movable coaxially with respect to each other and fixed together at each of their ends in a sealed and elastic manner by bearings in elastomeric material. /P
