RESILIENT VIBRATION ISOLATION DEVICE WITH BUILT-IN HYDRAULIC DAMPING AND INTERNAL TRAVEL STOPS

摘要

specific disclosure.the elastic device antivibratoire insulation atintegrated with a hydraulic damping device.an elastic membrane is thick, conicala rigid frame adhu00e9risu00e9e elastomeric compositiona rigid reinforcing internal and external, thebeing set in a rigid housing to form avariable volume chamber enclosing a damping fluid.in a column on the inertia of longwith respect to the middle section. a set ofprogressive articulation control stopspart of a wafer support is locked in thevariable volume chamber and a chamber formedexpansion of the liquid amortisaement returned by thearticulation is moved to the outside of the rigid casingthe elastic support boundary, thereby allowing for the adjustmentthe length of the liquid column and damping.therefore, the adjustment of the resonance frequency of thethe device. the invention finds an application in thesuspension of vehicle drive trains orheavy boxes.
