PERFECCIONAMIENTOS APORTADOS A LOS MANGUITOS HIDRAULICOS ANTI-VIBRATORIOS DE SUJECION

SE TRATA DE UN MANGUITO DE SUJECION QUE CONSTA DE DOS ARMAZONES RIGIDOS TUBULARES (1,2) QUE SE ENVUELVEN MUTUAMENTE, UNIDOS ENTRE SI MEDIANTE UN CUERPO ELASTOMERO (3) ADHERIDO A ELLOS Y CONFORMADO DE FORMA QUE CONSTITUYA AL MENOS DOS BOLSAS ESTANCAS (4,4'') LLENAS DELIQUIDO Y COMUNICADAS ENTRE SI POR UN CANAL ESTRECHO (5), PRESENTANDO DICHO CUERPO EN SECCION AXIAL LA FORMA GENERAL DE UNA X. EL CANAL SE EXTIENDE SEGUN UN ARCO DE CIRCULO TRANSVERSAL SITUADO AXIAL Y RADIALMENTE EN EL NIVEL DE LOS EXTREMOS DE LOS BRAZOS DE LA X. 1. Support sleeve having two rigid tubular frames (1, 2) surrounding each other mutually, joined together by an elastomer body (3) adhering thereto and shaped so as to form between said two frames at least two diametrically opposite sealed pockets (4, 4') communicating together through a narrow channel (5) which extends along a transverse arc of a circle having as axis the axis of the external frame and which is situated radially near the external tubular frame (2), inside said frame, the portion of the elastomer body which defines one at least of these pockets having in axial section the general form of a radially outwardly open V, and the assembly of the pockets and of the channel being filled with a damping liquid, characterized in that the channel (5) is situated near an axial end of the elastomer body (3).
