    • A fluid-filled cushioning device having a cylindrical elastic body mounted on an inner sleeve and having an orifice structure with an orifice formed therethrough is disclosed. A pair of annular elastic members each having a retainer member and an outer sleeve are mounted on the inner sleeve such that the retainer member is press-fitted in the axial end portion of the inner sleeve while the orifice structure is sandwiched between the axial end faces of the outer sleeves, in the axial direction. A bracket is mounted on the outer sleeves of the elastic members and is fixed to a support member, so that the bracket forces the outer sleeves against the orifice structure. The inner sleeve, elastic body and elastic members define two fluid-filled chambers which are separated from each other by the elastic body and which communicate with each other through the orifice. An axial dimension of each elastic member before being mounted on the inner sleeve is determined to permit each elastic member to be axially compressed upon mounting of the elastic members, so that the outer sleeves are urged against the orifice structure with a force sufficient to maintain fluid tightness between the elastic members and the orifice structure, whereby the mounting of the bracket on the outer sleeves of the elastic members may be effected in a condition that the fluid chambers are filled with the fluid.
    • 公开了一种流体填充缓冲装置,其具有安装在内套筒上并具有孔结构的圆柱形弹性体,孔结构具有通过其形成的孔口。 一对环形弹性构件,每个具有保持构件和外套筒,安装在内套筒上,使得保持构件压配合在内套筒的轴向端部中,同时孔结构夹在轴向端面 的外套,沿轴向。 支架安装在弹性构件的外套上,并固定在支撑构件上,使支架迫使外套靠在孔结构上。 内套筒,弹性体和弹性构件限定两个流体填充室,它们通过弹性体彼此分离并且通过孔彼此连通。 确定每个弹性构件在安装到内套筒之前的轴向尺寸,以允许每个弹性构件在安装弹性构件时被轴向压缩,使得外套件以足以维持流体的力被推靠在孔结构上 弹性构件与孔口结构之间的紧密度,从而可以在流体室充满流体的情况下将支架安装在弹性构件的外套上。

    • A fluid-filled elastic cushioning device for elastically connecting a first and a second member, including an inner sleeve attached to the first member, an elastic body fitted on the inner sleeve and having two pockets which are open in opposite axial end faces of the elastic body, two closure members for closing the open ends of the pockets to thereby form two fluid chambers, an orifice member embedded in the elastic body and having an orifice communicating with the fluid chambers, and a mounting plate secured to the orifice member. At least one of opposite ends of the orifice is open at a bottom of the corresponding at least one of the pockets, and at least one stopper rubber block is secured to each of at least one of the closure members which closes the corresponding at least one of the pockets. Each rubber block extends into the corresponding one of the fluid chambers such that a free end of each rubber block is normally spaced apart from the corresponding open end of the orifice. Each rubber block is abuttable at the free end thereof on the corresponding end of the orifice member, to thereby close the orifice at the corresponding open end, when the cushioning device is subjected to an excessive vibrational load.
    • 一种用于弹性连接第一和第二构件的流体填充的弹性缓冲装置,包括附接到第一构件的内套筒,弹性体装配在内套筒上,并且具有两个在弹性件的相对的轴向端面上敞开的口袋 两个闭合构件,用于封闭凹穴的开口端,从而形成两个流体室;嵌入在弹性体中并具有与流体室连通的孔口的孔口构件;以及固定到孔口构件的安装板。 孔口的相对端部中的至少一个在相应的至少一个凹穴的底部是开放的,并且至少一个止动橡胶块固定到至少一个封闭构件中的每一个上,封闭相应的至少一个 的口袋。 每个橡胶块延伸到相应的一个流体室中,使得每个橡胶块的自由端通常与孔口的相应开口端间隔开。 每个橡胶块在其孔口件的相应端部的自由端处可抵靠,从而当缓冲装置受到过大的振动负载时,封闭相应开口端的孔口。
