[0006] Furthermore, although Patent Document 2 discloses a configuration in which a caulking member for attaching a flexible film or the like is vulcanized and bonded to the main body rubber elastic body, in this configuration, the caulking member can be deformed due to deformation of the main body rubber elastic body. Relatively displaced with respect to the outer bracket, therefore, it is difficult to position the riveted part with sufficient precision relative to the outer bracket

Embodiment Construction

[0043] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0044] Figure 1 to Figure 5 In FIG. 1 , an engine mount 10 for an automobile is shown as a first embodiment of a fluid-filled anti-vibration device having a structure according to the present invention. The engine mount 10 has a structure in which an outer bracket 14 is fixedly bonded to an integral vulcanized molded product 12 . In the following description, in principle, respectively, the up and down directions refer to figure 1 In the up and down direction, the front and back direction refers tofigure 1 In the left and right direction, the left and right direction refers to the figure 2 in the up and down direction.

[0045] In more detail, as Figure 6 ~ Figure 9 As shown, the integrally vulcanized molded product 12 has a structure in which the inner mounting member 16 is vulcanized and adhered to the main body rubber elastic body 18 . The inner mounting memb...

Abstract

Provided is a fluid-filled vibration damping device having a novel structure, the fluid-filled vibration damping device being configured so that: the fluid-tightness of a fluid chamber can be ensured while the fluid-filled vibration damping device is simplified in structure by reducing the number of parts; and the fluid-filled vibration damping device can have excellent vibration damping performance. A fluid-filled vibration damping device 10 is configured so that: an inner mounting member 16 and an outer bracket 14 which is formed by molding will be elastically connected to each other by a main body rubber elastic body 18; and the fluid-filled vibration damping device 10 will be provided with a fluid chamber 84 which is filled with a non-compressive fluid and which has a wall, a part of which is configured from the main body rubber elastic body 18. A staking member 56 consisting of a material different from that of the outer bracket 14 is affixed in a protruding manner to the outer bracket 14. Cover members 66, 78 constituting other parts of the wall of the fluid chamber 84 are mounted to the outer bracket 14 by being affixed thereto by staking by means of the staking member 56.

Description

technical field [0001] The present invention relates to a fluid-enclosed type anti-vibration device that utilizes anti-vibration effects based on the flow action of an incompressible fluid enclosed inside, and the like. Background technique [0002] Conventionally, as one type of vibration isolating device interposed between components constituting a vibration transmission system and coupling these components to each other for vibration isolation, there is known a fluid-enclosed device that exhibits a vibration-isolating effect based on the flow of fluid enclosed inside. Type anti-vibration device, the fluid-enclosed type anti-vibration device is applied to the engine bracket of automobiles, etc. As disclosed in Japanese Patent No. 4199379 (Patent Document 1), etc., the fluid-enclosed anti-vibration device has the following structure: the inner mounting member and the outer mounting member are elastically connected by a main body rubber elastic body, The body constitutes a ...
