Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a fluid-filled mount comprising a mounting member connected to a vibration source and a base member on which the vibration source is mounted, coupled by at least two elastic members. Concerning improvements in assembly methods.

(Prior Art) The present applicant has previously disclosed in Japanese Patent Application No. 104737/1982 that sufficient damping is provided in both compression and tension directions.
Furthermore, we proposed a fluid-filled mount that is advantageous in terms of layout.

That is, as shown in FIG. 12, a mounting member (301) connected to a vibration source is divided into three parts (302), upper, middle, and lower.

(303) and (304), and the base member (310) fixed to the fixing member is also formed from three divided bodies (311), (312), and (313), which are upper, middle, and lower. three shear type elastic members (331), (332) for each pair of divided bodies.

(333), pass the rod through the mounting member (301) and combine with the nut, and also the base member (310).
) are combined with screws (341)...fasteners, etc., and the mounting member intermediate body (303) has an orifice (3 (16)
is formed.

According to such a mount, the cross-sectional area of the intermediate elastic member (332) that partitions into two fluid chambers is equal to that of the upper and lower elastic members (332).
1) Since it is larger than that of (333), it is possible to force the fluid to swing to the upper and lower fluid chambers even in both compression and tension directions, and therefore, sufficient damping can be achieved in both compression and tension directions. It is also compact and advantageous in terms of layout.

(Problem to be solved by the invention) However, in terms of manufacturing, each elastic member (331)
, (332), (333) are molded separately, and the mounting member (301) is also divided into parts (302), (303).
, (304) must be combined and assembled, resulting in a large number of steps and a high cost.

The present invention has been made in view of the above circumstances, and its purpose is to make it possible to make the mounting member into a single piece and mold a plurality of elastic members at the same time, to streamline the structure and reduce the manufacturing process.
