A partition plate 71 formed on the inner periphery of the cylindrical body 711
A small circular hole 716 is provided in the center of the circular hole 7.

The weight 750 floatingly supported in the circular hole 716 via the elastic member 760 resonates with the direction and phase of vibration reversed at the resonance point, so the vibrations are canceled out, but in the high frequency vibration region exceeding the resonance point, weight 75
0 has a small area, the upper and lower fluid chambers 703, 7
Due to the low fluid movement capacity within the base member 710 and the large area of the partition plate 715 integrated with the base member 710, micro vibrations are transmitted to the base member 710, as indicated by the broken line in FIG. As a characteristic, it was impossible to bring the dynamic magnification to high frequency vibration close to zero.

The gist is that the mount has been configured.
以下に本発明の好適実施例を添付図面に基づい
て詳述する。 Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

The lower periphery of an umbrella-like elastic member 30 made of rubber material is baked, and the periphery of a diaphragm 40 is baked on the lower part of the cylindrical body 11.
A disk-shaped mounting member 20 for connecting the vibration source is baked into the upper center of the vibration source.

ネジが突設されている。 Incidentally, the mounting piece 18 of the base member 10 is formed with mounting screw holes 19 for mounting to the fixed member, and although not shown, a mounting screw for mounting to the vibration source is provided protruding from the upper center of the mounting member 20.

なる厚肉円板状の錘５０の外周を焼付ける。 The outer periphery of an annular elastic member 60 made of a rubber material is baked onto the inner periphery of the intermediate portion of the cylindrical body 11 of the base member 10 constituting the peripheral wall of the fluid chamber 2 of the mount 1. , the outer periphery of the weight 50, which has a large area and a thick disk shape, is baked.

持したため、流体室２は上部流体室３と下部ダイ
ヤフラム室４とに画成される。 Since the annular elastic member 60 supports the large-area weight 50 in a floating manner across the fluid chamber 2, the fluid chamber 2 is defined into an upper fluid chamber 3 and a lower diaphragm chamber 4.
尚図示例では、錘５０の中央にオリフイス５１

室２内に流体（図示では液体）を封入する。 As described above, fluid (liquid in the drawing) is sealed in the fluid chamber 2 which is vertically defined by the weight 50.

つて動倍率を極めて低くすることができ、高周波
振動に対する遮断効果を高めることができる。 Since the large-area weight 50 is floatingly supported across the fluid chamber 2 of the fluid-filled mount 1, the base member 1
The force acting from the mounting member 20 to the base member 10 via the umbrella-shaped elastic member 30 that connects the mounting member 20 and the mounting member 20 and the mounting member 20 due to minute vibrations.
The fluid pressure generated in the fluid chamber 2 due to the minute vertical movement of the weight 50 that follows the change in relative position between the base member 10 and the base member 10, that is, in this case, the upper fluid chamber 3
The forces transmitted to the base member due to the fluid pressure inside are approximately balanced and cancel each other out. Therefore, the dynamic magnification can be extremely low, and the effect of blocking high frequency vibrations can be enhanced.
ところで高周波振動の遮断効果のより一層の確
実化を企図すれば、高周波振動領域における当該
流体入りマウント１の動倍率を略々零に設定する
必要がある。 By the way, in order to further ensure the effect of blocking high-frequency vibrations, it is necessary to set the dynamic magnification of the fluid-filled mount 1 to approximately zero in the high-frequency vibration region.

に吸収せしめれば良い。 Therefore, the force that is about to act on the base member 10 from the mounting member 20 via the umbrella-like elastic member 30 is applied to the upper part by the weight 50, which moves up and down in response to changes in the relative position between the mounting member 20 and the base member 10. It is only necessary to ensure that the fluid is absorbed by the fluid moving up and down in the fluid chamber 3.
そこで以下にその具体的解析を述べる。 Therefore, a specific analysis will be described below.

ある。 First, as shown in FIG. 2, the effective area of the umbrella-shaped elastic member 30 that participates in the movement of fluid in the fluid chamber 2 of the mount 1 is S E , and a weight 50 is floatingly supported transversely within the fluid chamber 2. The effective area of the inner periphery of the weight 50 and the annular elastic member 60 that supports it, which participates in the movement of fluid due to the vertical movement of S W
Furthermore, let S W −S E be S B. Here, the effective area of the elastic member is the area of the elastic member determined as the ability to contribute to fluid movement per unit relative displacement between the mounting member and the base member with the fluid chamber open to the atmosphere, and the effective area of the elastic member The area is the area of the weight determined as the ability to contribute to fluid movement per unit displacement of the weight with the fluid chamber open to the atmosphere.

意定数である。 Next, if we model the above mount 1, the 3rd mount
As shown in the figure, the effective area S E of the umbrella-like elastic member 30 with a spring constant k that determines the fluid movement ability has a spring constant ak, and the peripheral area that does not contribute to the movement of the fluid. S B naturally has a spring constant of k, and the spring constant of the effective area S W of the weight 50 is dk. Here, both a and d are arbitrary constants.

る。 The principle of the present invention is that a force P B acts on the cylindrical body 11 of the base member 10 through an area S B of the peripheral edge of the umbrella-like elastic member 30 due to the fluid pressure P, and a spring component (spring constant) of the elastic member 30 and k) are balanced and cancel each other out.
これを詳細に示せば次のようになる。 This can be explained in detail as follows.
先ず、取付部材からベース部材へ伝達される振
動の経路は次の２つに分けられる。 First, the paths of vibration transmitted from the mounting member to the base member are divided into the following two paths.
(イ) 弾性部材を通じて伝わる経路
(ロ) 流体室内の流体の圧力変動として伝わる経路
このうち(ロ)について更に説明を加えると、先
ず、取付部材に振動が入力されると取付部材とベ
ース部材間の相対位置が変化し、これによつて流
体室内の圧力が変動する。(b) A path transmitted through the elastic member (b) A path transmitted as pressure fluctuations of the fluid in the fluid chamber To further explain (b), first, when vibration is input to the mounting member, the vibration is transmitted between the mounting member and the base member. The relative position of the fluid chamber changes, which causes the pressure within the fluid chamber to fluctuate.
この時この圧力変動を発生させるのは弾性部材
の有効面積SEの部分であり、それ以外の流体室内
面ではこの圧力変動を等しく受けることになる。 At this time, it is the effective area S E of the elastic member that generates this pressure fluctuation, and the other surfaces of the fluid chamber are equally subjected to this pressure fluctuation.
しかしこの残りの流体室内面のうち、錘の有効
面積部分SWに作用する圧力変動は錘がフローテ
イング支持されているためにベース部材側へほと
んど伝達されない。 However, among the remaining fluid chamber surfaces, pressure fluctuations acting on the effective area SW of the weight are hardly transmitted to the base member side because the weight is supported in a floating manner.
以上において、前述した錘の有効面積が、弾性
部材の有効面積より大であるため、両有効面積の
差に相当する部分SBに作用する圧力変動が、取付
部材の変位方向と逆向きの力として弾性部材内面
に働くので、この力と前記(イ)の力が相殺されて全
体としての振動伝達を可及的に０に近づけること
ができる。 In the above, since the effective area of the weight mentioned above is larger than the effective area of the elastic member, the pressure fluctuation acting on the portion S B corresponding to the difference between the two effective areas causes a force in the opposite direction to the displacement direction of the mounting member. This force acts on the inner surface of the elastic member, so this force and the force (a) cancel each other out, making it possible to bring the overall vibration transmission as close to zero as possible.
従つてアンブレラ状弾性部材３０の周縁部の面
積は最低限零を越える、即ち正（SB＞０）でなけ
ればならない。 Therefore, the area of the peripheral edge of the umbrella-like elastic member 30 must at least exceed zero, that is, be positive (S B >0).
ここでSE＋SB＝SWであるから、SB＞０とする
ためには、SW＞SE、即ち錘５０の有効面積SWが
アンブレラ状弾性部材３０の有効面積SEよりも大
でなければならないことがわかる。 Here, since S E + S B = S W , in order to make S B > 0, S W > S E , that is, the effective area S W of the weight 50 must be larger than the effective area S E of the umbrella-shaped elastic member 30. I know it has to be big.
ところが取付部材２０と、ベース部材１０とを
結合する弾性部材３０は、図示の如く剪断特性を
具備したアンブレラ状の複雑形状をもつて構成さ
れているため、単純な計算によりその有効面積SE
を求めることはできない。 However, since the elastic member 30 that connects the mounting member 20 and the base member 10 has a complex umbrella-like shape with shearing properties as shown in the figure, its effective area S E can be calculated by simple calculation.
cannot be asked for.
そこで実際にテストを行つて弾性部材３０の有
効面積SEを求める。 Therefore, an actual test is performed to determine the effective area S E of the elastic member 30.
先ずテストに備え、アンブレラ状の当該弾性部
材３０を第４図に示す如く逆さにしてその周縁を
固定し、斯くして逆アンブレラ状を成す弾性部材
３０の上部に管体９０をその下部フランジ９１で
もつて固定する。ここで管体９０の上方は大気に
開放されている。 First, in preparation for the test, the umbrella-shaped elastic member 30 is turned upside down as shown in FIG. But hang it and fix it. Here, the upper part of the tube body 90 is open to the atmosphere.
斯かる管体９０内まで液体、例えば水を注入し
て静止させた後、逆アンブレラ状弾性部材３０の
中央下部に一体化した取付部材２０に第５図に示
す如く下方から変位量ｌmmなる強制変位を加え
る。この強制変位により液体のレベルが管体９０
内を上昇し、この増量容積Ｖmm3を実測する。 After injecting a liquid, for example water, into the tube 90 and letting it stand still, the mounting member 20 integrated at the lower center of the inverse umbrella-shaped elastic member 30 is forced to be displaced by lmm from below as shown in FIG. Add displacement. This forced displacement lowers the liquid level to the tube body 90.
The increased volume Vmm 3 is actually measured.
従つて求める弾性部材３０の有効面積はSE＝
Ｖ／ｌにより得られる。 Therefore, the effective area of the elastic member 30 is S E =
It is obtained by V/l.
一方錘５０についても以上と同様のテストを行
い、その有効面積SWを得、既述した解析結果の
通りSW＞SEに設定する。 On the other hand, the same test as above is carried out for the weight 50, and its effective area SW is obtained, and SW > S E is set as per the above-mentioned analysis results.
斯くして構成された本発明の流体入りマウント
１によれば、流体室２内に横断的にフローテイン

の面積SB部を経てベース部材１０に作用する力
と、該弾性部材３０のバネ成分による力とが釣り
合い、互いに打ち消し合うこととなる。 According to the fluid-filled mount 1 of the present invention configured in this way, the effective area S W of the large weight 50 floatingly supported across the fluid chamber 2 is
Since the effective area S E of the elastic member 30 that connects the mounting member 20 and the base member 10 is larger than the effective area S E, the effect acts on the base member 10 through the peripheral area S B of the elastic member 30, especially in the high frequency vibration region. The force and the force due to the spring component of the elastic member 30 are balanced and cancel each other out.
従つて換言すれば、取付部材２０から弾性部材

遮断効果をより一層確実に向上せしめることがで
きる。 Therefore, in other words, the force acting on the base member 10 from the mounting member 20 via the elastic member 30 is applied to the upper fluid by the weight 50, which moves up and down in response to changes in the relative position between the mounting member 20 and the base member 10. Since it is reliably absorbed by the fluid moving up and down in the chamber 3, the dynamic magnification of the mount 1 in the high frequency vibration region can be made approximately zero as shown by the solid line in FIG. As a result, the effect of blocking high-frequency vibrations can be improved even more reliably.

In addition, the desired effect can be achieved by changing the shape of the base member, etc., or even by changing the mount itself to an upright type or an inverted type, so examples of each modification are listed below. .

The lower outer periphery of an umbrella-shaped elastic member 130 having a hollow center portion is baked onto the inner periphery of the tapered portion 112 of the base member 110 formed with a truncated inverted conical shape. While baking the mounting member 120, an annular clamping part 113 having a U-shaped cross section that is open inward is formed at the lower part of the cylindrical body 111 of the base member 110, and this clamping part 1
The peripheral edge of the diaphragm 140 is inserted into the inside of the diaphragm 13 and connected by caulking.
