Embodiment Construction

[0097] First refer to figure 1 , shows an automotive engine mount 10 as one embodiment of the fluid-filled damping device according to the present invention. This engine mount 10 has a configuration in which a first mounting member 12 made of metal and a second mounting member 14 made of metal are connected to each other by a main rubber elastic body 16 . Then, the first mounting member 12, which is a part constituting the vibration transmission system, is mounted on a power unit of an automobile, not shown, and the second mounting member 14 is mounted on a vehicle body, not shown. , the second mounting member 14 is another component constituting the vibration transmission system, thereby providing a vibration-damping coupling of the power unit and the vehicle body via the engine mount 10 . In the following description, the up and down direction refers to the axial direction of the engine mount 10, and also refers to figure 1 The up-and-down direction in , which is consisten...

Abstract

A fluid filled type vibration damping device including: a partition member having a communication passage connecting a pressure receiving and equilibrium chambers; an obstructing rubber elastic plate juxtaposed against the communication passage from a pressure receiving chamber side, adapted to obstruct the communication passage, and arranged to be exposed to pressure of the pressure receiving and the equilibrium chamber at both faces; and a constraining member provided for retaining an outer peripheral section of the obstructing rubber elastic plate in contact against the partition member at multiple locations. The constraining member provides an opening / closing control member operated to induce the obstructing rubber elastic plate to push against the partition member and close off the communication passage, and to induce elastic deformation of the obstructing rubber elastic plate to be separated from the partition member.

Description

technical field [0001] The present invention relates to a vibration damping device adapted to be mounted between components to provide a vibration damped linkage, and more particularly to a fluid filled vibration damping device utilizing flow based action of a fluid sealed therein the damping effect. Background technique [0002] In the field of vibration-damping devices such as vibration-damping couplings or vibration-damping supports designed to be mounted between components that make up a vibration-transmitting system, a known device is a fluid-filled vibration-damping The damping effect of the flow action of the fluid inside. This fluid-filled vibration damping device has a first mounting member and a second mounting member coupled by a rubber elastic body. On the inner peripheral side of the second mounting member, a pressure receiving chamber whose wall is partially formed by the main rubber elastic body and a balance chamber whose wall is formed by the flexible memb...
