Abstract:
A hydraulic vibration-damping support designed to be interposed between two rigid elements for damping and interconnection purposes, said support comprising:two rigid strength members designed to be connected to respective ones of the two rigid elements to be interconnected; an elastomer body connecting together the two strength members; a working chamber filled with liquid and defined in part by the elastomer body; a flexible elastomer wall which is secured to the second strength member; a compensation chamber filled with liquid and defined in part by the flexible elastomer wall; a constricted passage filled with liquid and which puts the working chamber into communication with the compensation chamber; a rigid partition separating the working chamber from the compensation chamber, said rigid partition being provided with at least first and second gratings, each of which has a plurality of liquid-passing holes, the gratings defining between them a housing, the liquid-passing holes of one of the first and second gratings putting said housing into communication with the working chamber, and the liquid-passing holes of the other of the first and second gratings putting said housing into communication with the compensation chamber; and a decoupling flap made of elastomer and comprising a pad which has first and second faces facing respective ones of the first and second gratings, said pad being mounted with a small amount of clearance between said gratings, and said decoupling flap further comprising a first elastomer fastening member which projects from the first face of the pad, said first fastening member being fixed by clipping to the first grating; said vibration-damping support being wherein the decoupling flap further comprises a second fastening member which projects from the first face of the pad, said first and second fastening members being clipped into respective ones of two liquid-passing holes in the first grating, while leaving said liquid-passing holes unobstructed in part.
