Description

本発明は液封入式防振装置、より詳細には、主液室及び副液室内の液体が制限通路内を流動する際の通路内の液柱共振、液体が制限通路から受ける流動抵抗、弾性部材の変形等に基づいて、振動発生側に入力された振動を減衰するとともに、振動伝達側部材に対して絶縁する液封入式防振装置、なかでも、主液室と副液室とを区画する仕切部材の変形等による高周波防振特性の変化や、液圧上昇による異音の発生、仕切部材の構成部分の破損等を防止することが可能な液封入式防振装置に関するものである。   The present invention relates to a liquid-filled vibration isolator, and more specifically, liquid column resonance in the passage when the liquid in the main liquid chamber and the sub liquid chamber flows in the restricted passage, the flow resistance that the liquid receives from the restricted passage, and elasticity A liquid-filled vibration isolator that attenuates the vibration input to the vibration generating side and insulates it from the vibration transmitting side member based on deformation of the member, and in particular, separates the main liquid chamber and the sub liquid chamber The present invention relates to a liquid filled type vibration isolator capable of preventing a change in high-frequency vibration isolation characteristics due to deformation of a partition member to be generated, generation of abnormal noise due to an increase in liquid pressure, damage to a component part of the partition member, and the like.

従来、エンジン等の振動発生側部材から車体フレーム等の振動伝達側部材への振動の伝達を抑制するための防振装置としては、例えば特許文献１に記載されたもののように、装置内部に液体を封入した液封入式防振装置がある。   Conventionally, as an anti-vibration device for suppressing vibration transmission from a vibration generating side member such as an engine to a vibration transmitting side member such as a vehicle body frame, a liquid is provided inside the device, for example, as described in Patent Document 1. There is a liquid-sealed anti-vibration device in which

即ち、特許文献１には、「第１取付け具と、筒状の第２取付け具と、これらを連結するゴム状弾性材から成る防振基体と、前記第２取付け具に取付けられて前記防振基体との間に液体封入室を形成するダイヤフラムと、前記液体封入室を前記防振基体側の第１液室と前記ダイヤフラム側の第２液室に仕切る仕切り体と、前記第１液室と第２液室を連通させるオリフィスとを備え、前記仕切り体は、弾性仕切り膜と、この弾性仕切り膜の変位量をその両側から規制する一対の互いに連結された格子部材とから成る液封入式防振装置であって、前記第２取付け具の内周部と、少なくとも一方側の格子部材との間に弾性体が介在して、前記仕切り体が前記第２取付け具に弾性支持されている液封入式防振装置」が記載されており、この液封入式防振装置では、「より高い高周波数域で低動ばね化を図ることができる」とする。   That is, Patent Document 1 states that “a first mounting tool, a cylindrical second mounting tool, a vibration-proof base made of a rubber-like elastic material that connects them, and a second mounting tool that is attached to the second mounting tool and the anti-vibration base. A diaphragm that forms a liquid sealing chamber between the vibration base, a partition that partitions the liquid sealing chamber into a first liquid chamber on the vibration isolation base and a second liquid chamber on the diaphragm, and the first liquid chamber And an orifice for communicating the second liquid chamber, and the partition body is a liquid-filled type comprising an elastic partition membrane and a pair of interconnected lattice members that regulate the amount of displacement of the elastic partition membrane from both sides thereof In the vibration isolator, an elastic body is interposed between an inner peripheral portion of the second fixture and at least one lattice member, and the partition body is elastically supported by the second fixture. Liquid-filled vibration isolator "is described. The location, the "can be made low dynamic spring of a higher high frequency range."

しかし、このような従来技術において、加工の容易性及び軽量化等の観点から、前記仕切り体を合成樹脂材料によって形成した場合、その仕切り体が、装置内に封入した液体によって膨潤することにより、周面を剛性部材にて拘束されることになる前記格子部材が、仕切り体の厚み方向でいずれかの液室側に向けて凸となる形状に変形してしまうという問題があり、これによって、装置の高周波防振特性が変化し、また、液圧上昇による異音の発生、甚だしくは格子部材の破損等が生じるという問題があった。また、このような変形は、その仕切り体が、カシメ等による外力を受けた際にも同様に生じてしまうことが知られている。   However, in such a conventional technique, from the viewpoint of ease of processing and weight reduction, when the partition body is formed of a synthetic resin material, the partition body is swollen by the liquid enclosed in the apparatus, There is a problem that the lattice member whose peripheral surface is to be restrained by a rigid member is deformed into a shape that is convex toward one of the liquid chambers in the thickness direction of the partition, There has been a problem that the high-frequency vibration isolating characteristics of the apparatus are changed, and abnormal noise is generated due to an increase in fluid pressure, or the lattice member is severely damaged. In addition, it is known that such a deformation similarly occurs when the partition body receives an external force due to caulking or the like.

特開第２００５−２７３６８９号公報Japanese Patent Laid-Open No. 2005-27389

そこで、本発明は、主及び副液室間を仕切る仕切部材がカシメ等の外力を受けることによる仕切部材の構成部分の変位や、該構成部分を合成樹脂材料で形成した場合の材料の膨潤による変位を抑制し、装置の高周波防振特性の変化、液圧上昇による異音の発生、及び部材の変形による破壊が生じることのない液封入式防振装置を提供することを目的とする。   Therefore, the present invention is based on the displacement of the component part of the partition member when the partition member that partitions the main and sub liquid chambers receives external force such as caulking, and the swelling of the material when the component part is formed of a synthetic resin material. It is an object of the present invention to provide a liquid filled type vibration damping device that suppresses displacement and does not cause a change in high frequency vibration damping characteristics of the device, generation of abnormal noise due to an increase in fluid pressure, and destruction due to deformation of members.

発明者らは、上記課題を解決する液封入式防振装置を提供すべく鋭意検討していたところ、仕切部材において弾性仕切り膜（メンブラン）の変位量を規制する構成部分の少なくとも一方の形状を工夫して設計することが効果的であることを知見し、本発明を完成するに到った。

本発明の液封入式防振装置に用いることができる仕切部材９を底面図及び断面図で例示する図１（ａ）及び（ｂ）において、仕切部材９は、メンブラン１０と、メンブラン支持部１１と、メンブラン押さえ１２と、制限通路１３とを有する。メンブラン支持部１１には貫通孔１４が配されるとともに、該貫通孔１４は、図示例では、渦状に湾曲した８本の梁１５によって８つの窓１６に区画されている。
尚、図に示すところでは明確ではないが、メンブラン押さえ１２にも同様の貫通孔が配されており、この貫通孔は相互に交差する直線的な２本の梁によって４つの小窓に区画されている。ここで、メンブラン１０はゴム膜その他の膜状弾性体により、メンブラン支持部１１は合成樹脂材料により、そして、メンブラン押さえ１２は金属により、それぞれ構成されている。
また、図示例では、前記貫通孔１４の直径Ｄをφ４４、前記梁１５の幅Ｗを１．５ｍｍ、同梁１５の厚みｄを３ｍｍとしている。ここで、Ｗ及びｄは、Ｗ＜ｄの関係を満たすものとする。 In FIGS. 1A and 1B illustrating a partition member 9 that can be used in the liquid-filled vibration isolator of the present invention in a bottom view and a sectional view, the partition member 9 includes a membrane 10 and a membrane support portion 11. And a membrane retainer 12 and a restriction passage 13. A through hole 14 is disposed in the membrane support portion 11, and the through hole 14 is partitioned into eight windows 16 by eight spiral beams 15 in the illustrated example.
Although not clearly shown in the figure, the membrane retainer 12 is also provided with a similar through hole, and this through hole is divided into four small windows by two linear beams intersecting each other. ing. Here, the membrane 10 is composed of a rubber film or other film-like elastic body, the membrane support 11 is composed of a synthetic resin material, and the membrane retainer 12 is composed of metal.
In the illustrated example, the diameter D of the through hole 14 is φ44, the width W of the beam 15 is 1.5 mm, and the thickness d of the beam 15 is 3 mm. Here, W and d shall satisfy the relationship of W <d.

以上のような仕切部材９を適用してなる、本発明の液封入式防振装置は、前記メンブラン支持部１１及び前記メンブラン押さえ１２の少なくとも一方の貫通孔１４に設けた梁１５が、図示のように、仕切部材９の厚み方向と直角な平面内で湾曲していることを特徴とする。   In the liquid filled type vibration damping device of the present invention to which the partition member 9 as described above is applied, a beam 15 provided in at least one through hole 14 of the membrane support portion 11 and the membrane presser 12 is shown in the drawing. Thus, it is curved in a plane perpendicular to the thickness direction of the partition member 9.

梁１５を前記平面内でこのように湾曲させることにより、メンブラン１０の、図１（ｂ）の上下方向の変動量を変化させることなく、メンブラン支持部１１のカシメや膨潤等による半径方向内向きの変形を該梁１５の変形によって吸収させることができる。即ち、この構造によれば、仕切部材９のメンブラン支持部１１が、カシメ等による外力を受けて、或いは、装置内に封入した液体により膨潤して、半径方向の内方側に向けて変形した場合、各梁１５は、圧縮方向の力を受けることになるも、各梁１５は湾曲形態を有することから、それの厚み方向に撓むことなく、該厚み方向と直角の平面内で撓み変形することとなるので、各梁１５とメンブラン１０との間隔は常に一定に維持されることになる。
尚、図示例では、各梁１５に、前記仕切部材９の中心軸周りの湾曲度合を増す方向への周方向の撓みδΘを生じている。 By bending the beam 15 in this plane within the plane, the membrane 10 is radially inward due to caulking or swelling of the membrane support portion 11 without changing the amount of fluctuation in the vertical direction of FIG. Can be absorbed by the deformation of the beam 15. That is, according to this structure, the membrane support portion 11 of the partition member 9 receives an external force due to caulking or the like, or is swollen by the liquid sealed in the apparatus and deformed toward the inner side in the radial direction. In this case, each beam 15 receives a force in the compressing direction, but each beam 15 has a curved shape, so that it does not bend in its thickness direction, and is bent and deformed in a plane perpendicular to the thickness direction. Therefore, the distance between each beam 15 and the membrane 10 is always kept constant.
In the illustrated example, each beam 15 has a circumferential deflection δΘ in a direction in which the degree of curvature around the central axis of the partition member 9 is increased.

これがため、高周波振動入力に対する、メンブラン１０の変動量が変化することがなく、これによる装置の防振特性の変化を防止することができる。
即ち、本発明により、仕切部材に用いた構成部分のカシメ等の外力等に起因する、装置の特性変化や異音の発生及び部材の破壊等の不具合を防止した液封入式防振装置を提供することが可能となる。 For this reason, the fluctuation amount of the membrane 10 with respect to the high-frequency vibration input does not change, and the change in the vibration isolation characteristics of the apparatus due to this can be prevented.
That is, according to the present invention, there is provided a liquid-filled vibration isolator that prevents problems such as changes in device characteristics, abnormal noise, and member destruction caused by external forces such as caulking of components used in the partition member. It becomes possible to do.

また、本発明の防振装置においては、加工容易性の観点から、前記仕切部材９の厚み方向と直角な平面内で湾曲または屈折した形状を有する１本以上の梁によって複数の窓１６に区画された貫通孔１４を有する前記メンブラン支持部１１及び前記メンブラン押さえ１２の少なくとも一方を、合成樹脂によって構成することができる。この場合、合成樹脂で構成した構成部分の膨潤による変位も、本発明の構成によって抑制することができるため、装置の防振特性を損ねることなく加工容易性を確保することが可能である。   In the vibration isolator of the present invention, from the viewpoint of ease of processing, the plurality of windows 16 are partitioned by one or more beams having a curved or refracted shape in a plane perpendicular to the thickness direction of the partition member 9. At least one of the membrane support portion 11 and the membrane retainer 12 having the formed through-holes 14 can be made of a synthetic resin. In this case, since displacement due to swelling of the constituent parts made of synthetic resin can also be suppressed by the structure of the present invention, it is possible to ensure ease of processing without impairing the vibration isolation characteristics of the apparatus.

さらに、本発明を適用するにあたっては、図示例のように、前記梁１５を設けた貫通孔１４が円形である場合に好適である。貫通孔１４が円形であれば、仕切部材９が変形した場合に、貫通孔１４の孔縁の縮径方向変位が均一になりやすいため、例えば、各窓１６の面積が変形前後で不均一になってしまうことによる防振特性の変化等を効果的に抑制できる。   Furthermore, when the present invention is applied, it is suitable when the through hole 14 provided with the beam 15 is circular as shown in the illustrated example. If the through-hole 14 is circular, when the partition member 9 is deformed, the diameter-direction displacement of the hole edge of the through-hole 14 is likely to be uniform. For example, the area of each window 16 is not uniform before and after the deformation. It is possible to effectively suppress a change in the vibration proof characteristic due to becoming.

また、本発明の防振装置において、前記梁１５を設けた貫通孔１４を円形とした場合は、前記梁１５が、円弧状に湾曲しており、該円弧の曲率半径Ｒが前記貫通孔１４の半径Ｄ／２の０．５倍〜２．０倍であることが好ましい。曲率半径Ｒを前記貫通孔１４の半径Ｄ／２の０．５倍以上とすることにより、梁１５の耐久性を十分に確保することができ、一方、これを前記貫通孔１４の半径Ｄ／２の２．０倍以下とすることにより、前記構成部分の半径方向内向きの力を吸収する本発明の効果を十分に獲得することができる。   In the vibration isolator of the present invention, when the through hole 14 provided with the beam 15 is circular, the beam 15 is curved in an arc shape, and the radius of curvature R of the arc is the through hole 14. It is preferably 0.5 to 2.0 times the radius D / 2. By making the curvature radius R 0.5 times or more the radius D / 2 of the through hole 14, the durability of the beam 15 can be sufficiently ensured. By setting it to 2.0 times or less of 2, the effect of the present invention that absorbs the radially inward force of the component can be sufficiently obtained.

一方、本発明の防振装置では、貫通孔１４及び梁１５の他の形成例として概略的に示した図３（ｄ）のように、前記梁１５をジグザグ状等に屈折させることもできる。このような場合でも、梁１５の前記平面内での屈曲が促進されるため、装置の高周波防振特性の変化、液圧上昇による異音の発生、及び部材の変形による破壊を防止することができる。   On the other hand, in the vibration isolator of the present invention, the beam 15 can be refracted in a zigzag shape or the like as schematically shown in FIG. 3D as another example of forming the through hole 14 and the beam 15. Even in such a case, since the bending of the beam 15 in the plane is promoted, it is possible to prevent a change in the high-frequency vibration isolation characteristics of the device, generation of abnormal noise due to an increase in hydraulic pressure, and destruction due to deformation of the member. it can.

さらに、本発明の防振装置において、図示例のように、前記梁１５の厚み寸法ｄを該梁１５の幅寸法Ｗよりも大きくすることが好ましい。
Ｗ＜ｄとすれば、梁１５を前記平面内でより屈曲させやすくし、逆に厚み方向に屈曲させにくくさせることができるので、本発明による装置の防振特性の変化抑制効果をより有利に発揮させることができる。 Furthermore, in the vibration isolator of the present invention, it is preferable that the thickness dimension d of the beam 15 is larger than the width dimension W of the beam 15 as illustrated.
If W <d, the beam 15 can be bent more easily in the plane, and conversely, it can be made difficult to bend in the thickness direction. It can be demonstrated.

加えて、本発明の防振装置において、図示例のように、前記梁１５によって区画される複数の窓１６の配置が、前記平面内で回転対称であることが好ましい。
窓１６の配置を前記平面内で回転対称とすれば、メンブラン支持部１１に圧縮変形が生じた際に、各梁１５が均等に撓みやすくなる。また、撓みの発生前後で、複数の窓１６の配置の中心位置が変化しないため、例えば、図２に縦断面で示した防振装置のように、メンブラン１０の幅方向中心部をメンブラン支持部１１及びメンブラン押さえ１２の中心部によって拘束している場合に特に有利である。 In addition, in the vibration isolator of the present invention, it is preferable that the arrangement of the plurality of windows 16 partitioned by the beam 15 is rotationally symmetric in the plane as shown in the drawing.
If the arrangement of the windows 16 is rotationally symmetric within the plane, each beam 15 is easily bent evenly when the membrane support portion 11 undergoes compressive deformation. Further, since the center position of the arrangement of the plurality of windows 16 does not change before and after the occurrence of bending, for example, the center part in the width direction of the membrane 10 is the membrane support part as in the vibration isolator shown in the longitudinal section in FIG. 11 and the membrane retainer 12 are particularly advantageous when constrained by the central part.

以下に、図面を参照しながら本発明を詳細に説明する。
図２に示す実施形態において、液封入式防振装置１は、振動発生側もしくは振動伝達側のいずれか一方側の部材に連結されるコア部材２と、他方側に連結される筒状部材３と、筒状部材３を、一方の端部側でコア部材２の外周面に液密に連結する弾性部材４と、筒状部材３の他方の端部側に液密に取り付けたダイヤフラム５と、ダイヤフラム５の内側に区画される空間内に非圧縮性の液体を封入してなる流体室６と、流体室６をコア部材２側の主液室７とダイヤフラム５側の副液室８とに仕切る仕切部材９とを具える。 Hereinafter, the present invention will be described in detail with reference to the drawings.

尚、この仕切部材９は、先に記載した図１の仕切部材９と同一のものである。この仕切部材９は、図示例では、弾性部材４と筒状部材３とによって周囲を締付固定されており、拡径方向への変形を拘束されている。   The partition member 9 is the same as the partition member 9 of FIG. 1 described above. In the illustrated example, the partition member 9 is clamped and fixed around the elastic member 4 and the cylindrical member 3, and is restrained from being deformed in the diameter expansion direction.

ここで、この仕切部材９は、メンブラン支持部１１及び前記メンブラン押さえ１２のいずれか一方、図１及び２に示すところではメンブラン支持部１１の、貫通孔１４に配される梁１５が、仕切部材９の厚み方向に直角な平面内で湾曲した形状であることが肝要である。
尚、この場合、複数の梁１５間で、湾曲方向を相互に逆方向とすることも可能である。 Here, the partition member 9 includes a beam 15 arranged in the through-hole 14 of the membrane support portion 11 in either one of the membrane support portion 11 and the membrane presser 12, as shown in FIGS. 1 and 2. It is important that the shape is curved in a plane perpendicular to the thickness direction of 9.
In this case, the bending directions of the plurality of beams 15 can be opposite to each other.

図１に示すところでは、梁１５は、上記平面内で曲率半径Ｒの円弧状に湾曲しており、貫通孔１４の中央を中心点として回転対称に８本並んで配されている。
また、前記梁１５の幅Ｗ及び厚みｄは、Ｗ＜ｄを満たすものとする。ここで、特に限定するものではないが、梁１５の幅Ｗは、１〜３ｍｍ程度が好ましく、また、厚みｄは、２〜６ｍｍ程度が好ましい。 As shown in FIG. 1, eight beams 15 are curved in an arc shape having a radius of curvature R in the plane, and eight beams 15 are arranged in a rotationally symmetrical manner with the center of the through hole 14 as a center point.
In addition, the width W and the thickness d of the beam 15 satisfy W <d. Here, although not particularly limited, the width W of the beam 15 is preferably about 1 to 3 mm, and the thickness d is preferably about 2 to 6 mm.

尚、図２では、メンブラン支持部１１の貫通孔１４のみが、上記平面内で湾曲または屈折した梁１５によって区画されているが、本発明では、メンブラン支持部１１及びメンブラン押さえ１２の少なくとも一方の貫通孔が上記平面内で湾曲または屈折した梁によって区画されていればいいため、例えば、メンブラン支持部１１の貫通孔を直線状の梁によって区画し、メンブラン押さえ１２の貫通孔を、上記平面内で湾曲または屈折した梁によって区画することもでき、さらには、メンブラン支持部１１及びメンブラン押さえ１２の両方の貫通孔を、同様に区画することもできる。   In FIG. 2, only the through hole 14 of the membrane support portion 11 is defined by a beam 15 that is curved or refracted in the plane. In the present invention, at least one of the membrane support portion 11 and the membrane retainer 12 is used. Since the through hole only needs to be defined by a curved or refracted beam in the plane, for example, the through hole of the membrane support portion 11 is defined by a straight beam, and the through hole of the membrane retainer 12 is defined in the plane. It can also be defined by a curved or refracted beam, and furthermore, both the through holes of the membrane support 11 and the membrane retainer 12 can be similarly defined.

また、その際、貫通孔を上記平面内で湾曲または屈折した梁によって区画したメンブラン支持部１１及びメンブラン押さえ１２の少なくとも一方を合成樹脂によって構成すれば、合成樹脂の膨潤による変形も抑制することができる他、加工容易性を得ることが可能である。   At that time, if at least one of the membrane support part 11 and the membrane retainer 12 in which the through hole is defined by the curved or refracted beam in the plane is made of synthetic resin, deformation due to swelling of the synthetic resin can be suppressed. In addition, it is possible to obtain processability.

また、本発明において、合成樹脂製の構成部分に配する貫通孔１４の形状はどのような形状であってもよく、上記に例証した円形のものの他、例えば、図３（ａ）及び（ｂ）に示すような四角形等の多角形のもの等にも適用することが可能である。   Further, in the present invention, the shape of the through-hole 14 disposed in the synthetic resin component may be any shape. For example, in addition to the circular shape illustrated above, for example, FIGS. It is also possible to apply to a polygonal shape such as a quadrangle as shown in FIG.

また、貫通孔１４への梁１５の配し方としては、特に限定されるものではなく、例えば、図３（ａ）に示すもののように並列に配したり、図３（ｂ）に示すもののように十字型に交差させたり、また、図３（ｃ）に示すもののように格子状に配したりすることができる。   In addition, the way of arranging the beams 15 in the through holes 14 is not particularly limited. For example, the beams 15 may be arranged in parallel as shown in FIG. 3A or those shown in FIG. 3B. It can be crossed in a cross shape like this, or can be arranged in a grid like that shown in FIG.

図４（ａ）及び（ｂ）に示す仕切部材１０９は、仕切部材の厚み方向と直角な平面内で円弧状に湾曲する４本の梁１５を等間隔に設けることにより、貫通孔１０を相互に合同な４つの窓１６に区画したものであり、その他の点において、図１の仕切部材９と同一である。   A partition member 109 shown in FIGS. 4A and 4B is provided with four beams 15 that are curved in an arc shape in a plane perpendicular to the thickness direction of the partition member at equal intervals so that the through-holes 10 are mutually connected. Are divided into four windows 16 that are congruent to each other, and are otherwise the same as the partition member 9 of FIG.

また、図５（ａ）及び（ｂ）に示す仕切部材２０９は、直線状に延在して貫通孔１０の中心で相互に直角に交差する２本の直線的な梁１５によって、該貫通孔１０を相互に合同な４つの窓１６に区画したものである。   Further, the partition member 209 shown in FIGS. 5A and 5B has a through hole formed by two linear beams 15 that extend linearly and intersect each other at a right angle at the center of the through hole 10. 10 is divided into four windows 16 congruent with each other.

図４（ａ）及び（ｂ）に示したところに従って、本発明の仕切部材１０９のモデルを作成した。その際、梁１５の厚みｄ及び幅Ｗを表１に示すように異ならせた２つのモデルを作成し、これを実施例１及び２とした。尚、梁１５の曲率半径Ｒは１５ｍｍである。   A model of the partition member 109 of the present invention was created in accordance with what is shown in FIGS. 4 (a) and 4 (b). At that time, two models having different thicknesses d and widths W of the beam 15 as shown in Table 1 were created. The radius of curvature R of the beam 15 is 15 mm.

同様に、図５（ａ）及び（ｂ）に示したところに従って、表１に示すように梁１５の厚みｄ及び幅Ｗを異ならせた２つの仕切部材２０９のモデルを作成し、これを従来例１及び２とした。尚、実施例１及び２並びに従来例１及び２のそれぞれについて、貫通孔の直径Ｄをφ４４とした。   Similarly, as shown in FIGS. 5 (a) and 5 (b), models of two partition members 209 having different thicknesses d and widths W of the beam 15 as shown in Table 1 are created. Examples 1 and 2 were designated. In each of Examples 1 and 2 and Conventional Examples 1 and 2, the diameter D of the through hole was φ44.

かくして得られた従来例及び実施例の各モデルに対し、メンブラン押さえの形状、大きさ及び仕切部材の最大径の大きさが固定された拘束条件の下で、メンブラン支持部を３％膨張させた場合の、メンブランとメンブラン押さえとの間の距離の変化の最大量を測定し、従来例１を１００として指数化した。表１にその結果を示す。   For each model of the conventional example and the example obtained in this way, the membrane support portion was expanded by 3% under the constraint conditions in which the shape and size of the membrane presser and the maximum diameter of the partition member were fixed. In this case, the maximum amount of change in the distance between the membrane and the membrane holder was measured, and the conventional example 1 was indexed as 100. Table 1 shows the results.

Figure 2011122669
Figure 2011122669

表１に示すように、梁の厚みｄ及び幅Ｗが同一の場合、本発明による実施例１及び２は、従来例１及び２よりもメンブラン‐メンブラン押さえ間の距離変化の最大量が小さいことがわかる。また、実施例１と実施例２の結果を比較すれば、梁の厚みｄを梁の幅Ｗに対してＷ＜ｄとすることにより、さらにこの距離変化の最大量を小さくできることがわかる。   As shown in Table 1, when the thickness d and the width W of the beam are the same, Examples 1 and 2 according to the present invention have a smaller maximum amount of distance change between the membrane and the membrane presser than the conventional examples 1 and 2. I understand. Further, comparing the results of Example 1 and Example 2, it can be seen that the maximum amount of this distance change can be further reduced by setting the beam thickness d to W <d with respect to the beam width W.

上記結果より、本発明の液封入式防振装置は、仕切部材がカシメ等の外力を受けることによる仕切部材の構成部分の変位や、材料の膨潤による変位を効果的に抑制するものであると言える。   From the above results, the liquid-filled vibration isolator of the present invention effectively suppresses displacement of the component parts of the partition member due to external force such as caulking, and displacement due to swelling of the material. I can say that.
