とともに、振動減衰性能を損ねるという問題があった。(Problem to be solved by the invention) However, in such a liquid-filled elastic bushing, (
When assembling the outer cylinder, it is common to caulk and fix it to the outer periphery of the intermediate cylinder, so the crimping process deforms the throttle passage formed on the outer periphery of the intermediate cylinder, which is a rigid member, and prevents it from working as expected. Moreover, due to the caulking process, the incompressible liquid in the liquid chamber causes deformation of the elastic member in the circumferential and axial directions. acts to restrain their deformation, so a large initial stress acts locally on the interior of the elastic member and the joint surface between it and the intermediate cylinder, which reduces the durability of the elastic bushing and reduces vibration damping. There was a problem that performance was impaired.

ブツシュを捷供するものである。The present invention advantageously solves the problems of the prior art, and includes a throttle passage that is not affected at all or hardly by the caulking of the outer cylinder, and also eliminates the effect of locally large initial stress during the caulking. The purpose of the present invention is to provide a liquid-filled elastic bushing that effectively alleviates the problem and further reduces weight, processing steps, etc.

力が作用することがなく、耐久性がよくなる。(Function) In this liquid-filled elastic bushing, by caulking the outer cylinder of the elastic member with the intermediate ring attached to the end portion, sufficient liquid-tightness against the fluid sealed in the liquid chamber is provided. By forming multiple window holes in the elastic member, processing steps, material costs, and weight can be reduced compared to the conventional technology in which the intermediate cylinder is constructed. The intermediate rings do not restrict the circumferential deformation of the elastic members that partition the liquid chambers, and the intermediate rings are spaced apart from each other against deformation of the elastic members in the axial direction. This separation of the intermediate ring makes it difficult for the pressure inside the liquid to rise, making it easier for liquid resonance to occur and increasing the vibration damping effect. In the part or its neighboring part,
Durability is improved because large initial stress does not act locally on the elastic members and their joint surfaces.

もたらされる。Furthermore, the diameter of the low-rigidity restricting passage provided on the inner or outer surface of the elastic member or inside the elastic member is expanded due to the increase in the internal pressure of the liquid during caulking of the outer cylinder. By determining the diameter of the throttle passage by taking into account the expansion of the passage diameter due to the increase in the internal pressure of the chamber, the initial vibration damping effect can be achieved under the passage length that meets the requirements.

め、液中でのへ方絞りとすることが好ましい。Here, the elastic member 3 made of rubber, rubber-like elastic material, etc. is fixed to the inner cylinder 1 by vulcanization adhesive, bonding with an adhesive or adhesive, and 1, the outer cylinder 2 thereof is fixed. At the center part of the elastic member 3 in the axial direction, the outer cylinder 2 is caulked directly to the outer peripheral surface of the elastic member 3, and at the end part, the outer cylinder 2 is fixed to the elastic member 3 by applying, for example, vulcanized adhesive. This is achieved by caulking the outer cylinder 2 to the intermediate rings 4, 4 which have been formed. Therefore, the elastic member 3
The diameter of the part of the outer cylinder 2 where the outer cylinder 2 is directly caulked is slightly larger than the outer diameter of the intermediate ring 4.4 so as not to create a gap between the elastic member 3 and the outer cylinder 2. It is necessary to Note that the caulking process here is preferably performed by drawing in a hexagonal direction in a liquid in order to prevent air from flowing in and to prevent the O-ring from getting caught.

る。Further, here, the elastic member 3 is provided with two diametrically opposed depressions 3a at its central portion in the axial direction, and the space formed by the depressions 3a, the intermediate ringay, and the outer cylinder 2 is inserted into the elastic member 3. By enclosing an incompressible liquid, two opposing liquid chambers 5 are formed, and each of these liquid chambers 5 includes:
A stopper 6 protruding from the inner cylinder side or the outer cylinder side is provided. This stopper 6, which is not an essential component in the present invention and protrudes from the inner cylinder side in the illustrated example, is formed by, for example, fitting and fixing a bossed rigid member 7 to the inner cylinder 1, and attaching the elastic member 3 to the surface thereof. The stopper 8 can be constructed by covering the elastic material 8 of the same quality, and when the amount of relative displacement between the inner and outer cylinders 1.2 becomes excessive, the stopper 8 prevents the relative displacement from occurring under the buffering action of the elastic material 8. It acts to restrain.

。Furthermore, in this example, in the part of the elastic member 3 where the outer cylinder 2 is caulked directly, the elastic member 3 and the outer cylinder 2 are
A low-rigidity throttle passage 9 is provided between the liquid chamber 5.5 and the liquid chamber 5.5. This throttle passage 9 is, for example, shown in FIG.
), a groove 3b is provided on the outer periphery of the elastic member 3 and has a curved cross-sectional shape such as an arc shape or a U-shape;
In addition to the groove facing portion of the outer cylinder 2 which is caulked onto the elastic member to close the opening of the groove 3b, the inner groove 3b provided as shown in FIG. fart,
It can also be constructed by fitting pipes 10 of low rigidity tightly together as shown in FIG. 2(b).

Alternatively, the cross-sectional shape of the restrictor passage 9 may be changed to a radially inner position of the elastic member 3, as long as a sufficient restrictor passage length is ensured to provide the desired vibration damping. It can be provided in a curved or angular shape, in a straight line or in red and white.

所期した通りに減衰されることになる。According to such a liquid-filled elastic bushing, the intermediate ring 4.4, which can be made of steel, for example, provides sufficient liquid tightness in the axial direction of the bushing by caulking the outer cylinder 2 thereto, and also provides elastic The central part of the member 3 provides liquid tightness in the circumferential direction of the bushing by caulking the outer cylinder 2 thereto. Therefore, the flow of the incompressible fluid in the bunsch takes place only through the restriction passage 9, and the restriction passage 9, whose length is appropriately selected, causes various energy losses to the liquid passing therethrough. Therefore, vibrations transmitted to the inner cylinder or outer cylinder are damped as expected by the energy loss.

る。Note that since a simple ring is sufficient as the intermediate ring 4.4 here, the number of processing steps, material cost, and weight are reduced compared to the prior art. Moreover, these intermediate rings 4, which are fixed only to both ends of the elastic member 3,
4, when caulking the outer cylinder 2, the deformation of the elastic member 3 in the circumferential direction and the axial direction is not restrained so much, so the increase in internal pressure in the liquid chamber is small, liquid resonance is more likely to occur, and the vibration damping effect is increased. Further, a large initial stress does not act on the joint portions of the elastic member 3 to the intermediate rings 4, 4 or the vicinity thereof, and therefore the durability and vibration damping characteristics of the elastic bushing are improved.

The vibration damping function can be achieved as expected.

It is also possible to have three or more liquid chambers.

This reduces the processing time, material cost, and weight of the intermediate ring itself and the elastic bushing, and also reduces the damping effect due to the increase in hydraulic pressure when assembling the outer cylinder, deforms the throttle passage, and reduces local This means that the generation of a large initial stress can be sufficiently and effectively prevented.
