摘要： A hydraulic antivibration device arrangement capable of achieving a downsizing and weight reduction, and a reduction of booming noise by suppressing a reaction force to impingement upon stopper action is provided. By disposing a protuberant rubber portion 35 at an upper end of a main body member 2, its spacing distance from a roll center can be lengthened, the reaction force to impingement can be diminished, and input load to the main body member 2 can be diminished. Consequently, reduction of rigidity and strength required for respective components as well as enhancement of durability is possible, which permits to make the components thin-walled thereby making a hydraulic antivibration device arrangement 100 lightweight as a whole. Diminishing of such reaction force upon stopper action also enables vibrations input through a car body side bracket 120 to the body frame to be suppressed, thereby reducing the generation of booming noise.

摘要： A liquid-sealed anti-vibration device wherein an annular space is formed between an orifice member and a partition plate member, crimped and fixed downwardly of the orifice member to an anti-vibration device proper, of a partition; and a rubber-like elastic membrane is disposed in the space and has a base portion attached fixedly to the one of the orifice member and the partition plate member and an open terminal at a distal side, the open terminal being slidably in pressure contact with the other, thus constituting a cantilevered sliding membrane structure. Thereby it is possible to diminish the amplitude dependency, to reduce the dynamic spring constant in a wide spectrum of medium and high frequencies, and to lower the noise.

摘要： A liquid-sealed vibration-proof device is constructed so that a partition dividing its interior into a main and a subsidiary liquid chamber comprises an orifice member having an orifice, a partition plate member provided subjacently in contact with the orifice member, and an elastomeric membrane interposed between a central plate section of the orifice member and the partition plate member. The elastomeric membrane includes a central plate-form portion held and pinched by the orifice and partition plate members, and a diaphragm portion extending outboard it to terminate at an open end which is slidably brought in pressure contact with an annular wall section of the orifice member. Openings are provided in the central plate section and the partition plate member holding and pinching the central plate-form portion, which is partly exposed to both chambers, as an elastic membrane capable of elastic deformation.
