The inner cylinder and the outer cylinder are shown respectively, numeral 3 represents a rubber elastic ring integrally fixed to the inner and outer cylinders 1 and 2, and numeral 4 represents a sleeve fitted over the outer cylinder 2 in a liquid-tight manner. Here, two liquid chambers 5 separated in the circumferential direction are formed by the rubber elastic ring 3 and the through hole of the outer cylinder 2, and a throttle passage 6 that interconnects the liquid chambers 5 is formed on the outer periphery of the outer cylinder 2.

動減衰性能を損ねるという問題があつた。 In the production of such vibration-proof bushings, the prior art filling process of damping liquid is generally carried out using inner and outer cylinders 1 and 2 and a rubber elastic ring 3 that are integrated with each other.
This is done by assembling the cannula 4 in the liquid, or by inserting a needle such as a hypodermic needle in the axial direction of the rubber elastic ring 3 and injecting damping liquid after the assembly of each component is completed. Because I was
According to the former method, each anti-vibration bushing has four sleeves.
The latter method requires repeating the submerged assembly work, resulting in poor workability.Also, it is difficult to achieve a complete liquid-tight seal after assembling the cannula 4. However, with the latter method, the liquid injection operation Because of this, the workability is worse than that of the former, and since the air present in the liquid chamber 5 and the throttle passage 6 cannot be extracted, air pockets are generated in those closed spaces. There was a problem that this impairs the vibration damping performance of the anti-vibration bushing.
この発明は、従来技術のこれらの問題を有利に

る。 The method for manufacturing a vibration isolator according to the present invention includes the steps of manufacturing a vibration isolator configured by liquid-tightly sealing a liquid chamber formed entirely or mostly in an elastic body with a partition member. Assembling the partitioning member to the elastic body without filling the liquid chamber with liquid, providing an opening in the partitioning member at a position corresponding to the liquid chamber, preferably before assembling the partitioning member, and after assembling the partitioning member. The liquid chamber is evacuated through the opening, and while maintaining this vacuum state, liquid is filled from the opening into the liquid chamber and the throttle passage, and then the opening is closed, for example, by welding.
以下にこの発明を図面に基づいて説明する。 The present invention will be explained below based on the drawings.
第２図は、この発明を適用する防振装置の一例
としての防振ブツシユを示す断面図であり、図中
第１図と同様の部分はそれと同一の番号で示す。 FIG. 2 is a sectional view showing a vibration isolating bushing as an example of a vibration isolating device to which the present invention is applied, and the same parts as in FIG. 1 are designated by the same numbers.

室５および絞り通路６を液密に封止する。 In this example, a rubber elastic ring 3 is vulcanized and bonded to a metal inner cylinder 1 and an outer cylinder 2 that are arranged concentrically, and two depressions 3a are formed on the outer periphery of the rubber elastic ring 3 so as to oppose each other in the diametrical direction. and two liquid chambers 5 separated in the circumferential direction by the through holes 2a of the outer cylinder 2 that open at these recess positions.
Furthermore, a throttle passage 6 of a predetermined width and depth is provided on the outer periphery of the outer cylinder 2 to interconnect each through hole 2a and thus the liquid chamber 5. Here, as is clear from FIG. 2b, the sleeve tube 4, which is also made of metal and serves as an example of the partitioning member, is bonded to the inner surface of the rubber elastic ring 3 that penetrates the outer tube 2 and reaches its outer surface. The liquid chamber 5 is formed by press-fitting the mantle 4 coated with the agent and re-vulcanizing it, or by adhering the mantle 4 to the outer surface of the outer cylinder 2 and the rubber elastic ring 3 using only an adhesive. And the throttle passage 6 is sealed liquid-tightly.

その接着前に予め形成することが好ましい。 In this case, the opening 7 provided in the position corresponding to the liquid chamber 5 of the cannula 4 can be formed after the cannula 4 is bonded in this manner, but this may prevent chips from entering the liquid chamber 5. In order to reliably prevent
Preferably, it is preformed before its adhesion.

This stopper 8 is a radially protruding portion of a rigid member 8a fixed to the inner cylinder 1, which reliably prevents abnormal displacement of the rigid member 8a, and a rubber covering the protruding portion. The elastic ring portion provides a damping effect.

により、防振ブツシユが完成する。 After assembling each component as described above,
In order to fill each liquid chamber 5 and the throttle passage 6 with liquid, a plurality of the assemblies 9 are first housed in a vacuum container 10 as shown in FIG. Vacuum container 10
A vacuum is created within the liquid chamber 5 and the throttle passage 6 of the assembly 9. Next, while the valve 12 between the vacuum container 10 and the vacuum pump 11 is closed to maintain the vacuum state inside the container 10, the valve 14 of the liquid tank 13 connected to the container 10 is opened to pour liquid into it. supply As a result, the liquid flows into the liquid chamber 5 and the throttle passage 6 through the opening 7 of the assembly 9 without any restriction in its flow and completely fills them. Finally, the anti-vibration bushing is completed by closing the opening 7, for example by welding in the liquid or after the assembly 9 has been removed from the vacuum vessel 10.
従つて、この方法によれば、液体の充填が完全
にしかも能率的に行われることになり、また十分

It can also be applied to a vibration-proof bushing in which the throttle passage 6 is directly formed on the outer periphery of the rubber elastic ring 3 without using the cylinder 2.

確実なる液体の封入が行われる。 FIG. 4 is a cross-sectional view showing a further example of application of the present invention. For example, this vibration-proof rubber 21 can be used as an engine mount of an automobile.
A dish-shaped or bowl-shaped liquid chamber 23 is formed at the top of the rubber or rubber-like elastic body 22, and the liquid chamber 23 is formed into a substantially truncated conical shape by a throttle passage 24 provided at the bottom of the liquid chamber 23. It communicates with a sub-chamber (the sub-chamber is closed as the illustrated example shows a no-load state) formed between the shaped inner lower surface and the flexible membrane 25 fixed along the inner lower surface. ,moreover,
It is constructed by fixing a lid plate 26 as a partitioning member to the upper end of the elastic body 22 to liquid-tightly seal the liquid filled in the liquid chamber 23 and the throttle passage 24. In this case, a vacuum is created in the liquid chamber 23 and the throttle passage 24 through an opening 27 provided in the cover plate 26, and the liquid is filled through the opening 27 while maintaining the vacuum state, and then the opening 27 is closed. Thus, liquid can be easily and reliably sealed.

It goes without saying that the present invention can be similarly applied to known liquid-filled vibration isolators other than the illustrated example. It is also possible to close the opening by a method other than welding, such as a rivet or a screw coated with a sealing adhesive.

密封止を容易かつ確実にもたらすことができる。 Therefore, according to the present invention, an opening is provided at a position corresponding to the liquid chamber in the partitioning member assembled to the elastic body in a state in which no liquid is sealed, and the liquid chamber is evacuated through the opening, and the vacuum is removed. By filling the liquid into the liquid chamber through the opening while maintaining the state, and then closing the opening, complete filling of the liquid and liquid-tight sealing can be easily and reliably achieved with extremely high liquid filling work efficiency. I can do it.
