Embodiment Construction

[0057] see first figure 1 , shows the automobile engine mount 10 belonging to the fluid-filled damping device according to the first embodiment of the present invention. This engine mount 10 is composed of a first metal mounting part 14 and a second metal mounting part 16 , said mounting parts being elastically connected via a main rubber elastic body 18 . Although not shown in the figure, the first mount 14 is attached to the power unit side, and the second mount 16 is attached to the body side of the automobile through a bracket 20 as a holding member, so that the power unit It is supported on the vehicle body in a vibration-damping manner. In the following descriptions, the vertical direction in principle refers to figure 1 The vertical direction in , which indicates the substantially vertical direction of the installed mounting piece, that is, the input direction of the main vibration load.

[0058]More specifically, the first mounting member 14 is a vertically extendin...

Abstract

A fluid filled vibration damping device including an elastic body connecting a first and second mounting member, a pressure-receiving chamber defined by the elastic body and an equilibrium chamber defined by a flexible rubber film. The second mounting member is press fitted into a tubular holder member having an annular holding portion integrally formed at its lower end projecting radially inwardly. A cover plate member having an outside diameter smaller than an inside diameter of the holder member is disposed within the holder member with an outer peripheral portion is fixedly clamped by the second mounting member and the annular holding portion. A sealing rubber is disposed for fluid-tightly closing a gap formed between the clamped portion so that an tightly closed air chamber defined by the cover plate member is formed on a back side of the flexible rubber film.

Description

[0001] cross reference [0002] The entire disclosures of Japanese Patent Application No. 2006-023658 filed on January 31, 2006 and Japanese Patent Application No. 2006-267400 filed on September 29, 2006, including the specification, drawings and abstract, are incorporated herein by reference. technical field [0003] The present invention relates to a fluid-enclosed vibration damping device capable of exhibiting a vibration damping effect based on the flow action of a sealed non-compressible fluid flowing through a connection between a pressurized chamber and a balance chamber, and a method for manufacturing the device. orifice passages between them. Background technique [0004] Fluid-enclosed vibration dampers are known in the art for installation between components constituting a vibration transmission system, capable of exhibiting a damping effect based on resonance or other flow effects or properties of a non-compressible fluid sealed therein Devices such as damping s...
