Abstract:
(EN) Provided is a fluid-filled vibration-proof device which has a novel structure and with which a partitioning member can be stably positioned with respect to an outer member in the axial direction, and superior vibration-proof performance can be achieved. According to this fluid-filled vibration-proof device 10, an inner peripheral surface of a cylindrical part 22 of the outer member 14 has a rectangular cylinder shape, the partitioning member 35 formed in a rectangular plate shape to correspond to the inner peripheral surface 24 of the cylindrical part 22 is arranged on the inner peripheral side of the cylindrical part 22, and the outer peripheral surface of an axial end part of a main rubber elastic body 16 is fixed to the inner peripheral surface 24 of the cylindrical part 22. While an annular seal rubber part 29 pressed against the outer peripheral edge part of the axial end surface of the partitioning member 35 is provided on an axial end part of the main rubber elastic body 16, the internal dimension of the seal rubber part 29 in the direction perpendicular to the axis is formed to be greater in the diagonal direction than in the opposite side direction of the inner peripheral surface 24 of the cylindrical part 22, and the width dimension of the seal rubber part 29 is greater in the diagonal direction than in the opposite side direction of the inner peripheral surface 24 of the cylindrical part 22.
(FR) L'invention concerne un dispositif anti-vibrations rempli de fluide présentant une structure innovante et permettant le positionnement stable d'un élément de séparation par rapport à un élément externe dans la direction axiale, et permettant d'obtenir une efficacité anti-vibrations supérieure. Selon le dispositif anti-vibrations rempli de fluide (10), une face périphérique interne d'une partie cylindrique (22) de l'élément externe (14) se présente sous une forme de cylindre rectangulaire, l'élément de séparation (35), prenant une forme de plaque rectangulaire pour correspondre à la face périphérique interne (24) de la partie cylindrique (22), est agencé sur le côté périphérique interne de la partie cylindrique (22), et la face périphérique externe d'une partie d'extrémité axiale d'un corps élastique principal en caoutchouc (16) est fixée à la face périphérique interne (24) de la partie cylindrique (22). Bien qu'une partie d'étanchéité annulaire en caoutchouc (29), appuyée contre la partie de bord périphérique externe de la face d'extrémité axiale de l'élément de séparation (35), soit agencée sur une partie d'extrémité axiale du corps élastique principal en caoutchouc (16), la dimension interne de la partie d'étanchéité en caoutchouc (29) dans la direction perpendiculaire à l'axe est façonnée pour être plus grande dans la direction diagonale que dans la direction latérale opposée de la face périphérique interne (24) de la partie cylindrique (22), et la dimension de la largeur de la partie d'étanchéité en caoutchouc (29) est plus grande dans la direction diagonale que dans la direction latérale opposée de la face périphérique interne (24) de la partie cylindrique (22).
(JA) 仕切部材をアウタ部材に対して軸方向で安定して位置決めすることができると共に、優れた防振性能を実現することができる、新規な構造の流体封入式防振装置を提供すること。 流体封入式防振装置10において、アウタ部材14の筒状部22の内周面が四角筒状とされていると共に、筒状部22の内周面24に対応する四角板状とされた仕切部材35が筒状部22の内周側に配設されており、本体ゴム弾性体16の軸方向端部の外周面が筒状部22の内周面24に固着されていると共に、本体ゴム弾性体16の軸方向端部には、仕切部材35の軸方向端面の外周縁部に押し付けられる環状のシールゴム部29が設けられている一方、シールゴム部29の軸直角方向の内法寸法が筒状部22の内周面24の対角方向において対辺方向よりも大きくされていると共に、シールゴム部29の幅寸法が筒状部22の内周面24の対角方向において対辺方向よりも大きくされている。
