(57) [Summary] [Purpose] To provide a liquid-filled mount structure capable of obtaining a reliable damping characteristic with respect to complicated vertical, horizontal and lateral movements. [Structure] The partition 4 is formed integrally with the anti-vibration rubber 1. A concave groove 9 is provided in a movable plate 5 that fits with the partition portion 4 with a predetermined gap and slides along the outer cylinder 8. The partition 4 and the movable plate 5 divide the liquid chamber into upper and lower parts. One end of the groove 9 communicates with the upper liquid chamber 6 and the other end communicates with the lower liquid chamber 7. Thus,
The liquid enclosed in both liquid chambers 6 and 7 flows through the flow path formed with the concave groove 9 according to the change in volume. Since the flow path functions as an orifice, a large damping is obtained by viscous resistance generated when the liquid flows.
Description
【０００１】[0001]
本考案は、車両における防振を目的としてキャブマウントなどに使用される液 体封入マウント構造に関する。 The present invention relates to a liquid-filled mount structure used for a cab mount or the like for the purpose of vibration isolation in a vehicle.
【０００２】[0002]
車両の走行に伴って発生する振動を吸収し、乗員に快適な車室内環境を提供す る目的で使用されるマウント構造としては、同心状に配置した内外筒間に防振ゴ ム体を設けたものが多用されている。 As a mount structure that is used to absorb the vibration generated as the vehicle travels and to provide a comfortable passenger compartment environment for the occupants, an anti-vibration rubber body is provided between the inner and outer cylinders arranged concentrically. Many things are used.
【０００３】 ところで、上述したようなマウント構造においては、高周波域の騒音を低減す るために低い動的ばね定数を備えると共に、低周波数域の振動を低減するために 高い減衰係数を備えた防振ゴム体の特性が要求され、従って、防振ゴム体の動的 ばね定数と減衰係数とは不可分の関係にある。しかし、高周波域での振動騒音を 低減するために動的ばね定数の低い防振ゴムを使用すると、ゴムの損失係数が小 さいために減衰係数も小さくなり、低周波域での振動減衰効果が期待できないと いった不具合が発生する。By the way, the mount structure as described above has a low dynamic spring constant in order to reduce noise in a high frequency range, and an anti-insulation mechanism having a high damping coefficient in order to reduce vibration in a low frequency range. The characteristics of the rubber vibrating body are required, and therefore, the dynamic spring constant and the damping coefficient of the vibration damping rubber body are inseparable. However, if a vibration-damping rubber with a low dynamic spring constant is used to reduce vibration noise in the high frequency range, the damping coefficient becomes small because the loss coefficient of the rubber is small, and the vibration damping effect in the low frequency range is reduced. Problems that cannot be expected occur.
【０００４】 これを解消するため、防振ゴム体内に形成した液室内に液体を封入する液体封 入マウントが考案されている。この液体封入マウントは、液体の流通抵抗を利用 して振動を減衰させるもので、たとえば実開平１−１１３６４７号公報に開示さ れたものがある。In order to solve this, a liquid sealing mount has been devised for sealing a liquid in a liquid chamber formed in a vibration-proof rubber body. This liquid-filled mount damps vibration by utilizing the flow resistance of the liquid, and is disclosed in, for example, Japanese Utility Model Laid-Open No. 1-113647.
【０００５】[0005]
前述した従来の液体封入マウント構造は、図７に示す如く、外筒０８と可動板 ０５との間に流体の流路０１０として形成された隙間ｔをオリフィスとし、該オ リフィスを通過する粘性抵抗で振動を減衰させるものであった。しかしながら、 このような構造では可動板０５が左右方向に動きうるため、該可動板０５と外筒 ０８とで形成されるオリフィスの断面形状に変化を生じることが考えられる。ま た、内筒０２あるいは外筒０８に左右方向の力が作用し、該内筒及び外筒が左右 方向に相対変位させられる場合、仕切部０４、可動板０５及び外筒０８で形成さ れた所定の間隙を越える相対変位に対し、ばね定数が急激に上昇し、またかかる 状況下においては可動板０５の円滑な作用が妨げられる恐れがあった。 As shown in FIG. 7, the conventional liquid-filled mount structure described above uses a gap t formed as a fluid flow path 010 between the outer cylinder 08 and the movable plate 05 as an orifice, and viscous resistance passing through the orifice. It was intended to damp the vibration. However, in such a structure, since the movable plate 05 can move in the left-right direction, it is considered that the cross-sectional shape of the orifice formed by the movable plate 05 and the outer cylinder 08 changes. Further, when a force in the left-right direction acts on the inner cylinder 02 or the outer cylinder 08 and the inner cylinder and the outer cylinder are relatively displaced in the left-right direction, they are formed by the partition part 04, the movable plate 05, and the outer cylinder 08. Moreover, the spring constant sharply rises with respect to the relative displacement exceeding the predetermined gap, and in such a situation, the smooth action of the movable plate 05 may be hindered.
【０００６】 そこで、本考案の目的は、車両に実際に使用される場合のように、上下左右複 雑な動きに対して、確実な減衰特性が得られる液体封入マウント構造を提供する ことにある。[0006] Therefore, an object of the present invention is to provide a liquid-filled mount structure capable of obtaining a reliable damping characteristic with respect to a complicated movement in up, down, left and right such as when actually used in a vehicle. ..

本考案は、前述の課題を解決するもので、同心状に配置した内外筒間に防振ゴ ムを設け、該防振ゴムに形成した液室内に液体を密閉封入して成る液体封入マウ ント構造において、前記内筒側から水平に突出して前記液室を上部液室と下部液 室とに分割する仕切部と、該仕切部との間に所定の間隙をもって嵌合され、前記 仕切部と共に前記液室を分割する可動板と、前記外筒の内面を摺動する前記可動 板の外周面に沿って形成され、一端を前記上部液室に連通せしめると共に他端を 前記下部液室に連通せしめた凹溝とを具備し、前記外筒の内面と前記凹溝との間 に形成されて上下液室を連通せしめる液体の流路を設けたことを特徴とする液体 封入マウント構造である。 The present invention solves the above problems, and a liquid-filled mount in which a vibration-proof rubber is provided between inner and outer cylinders arranged concentrically, and a liquid is hermetically sealed in a liquid chamber formed in the vibration-proof rubber. In the structure, a partition portion that horizontally projects from the inner cylinder side and divides the liquid chamber into an upper liquid chamber and a lower liquid chamber is fitted with a predetermined gap between the partition portion and the partition portion. It is formed along a movable plate that divides the liquid chamber and an outer peripheral surface of the movable plate that slides on the inner surface of the outer cylinder, and has one end communicating with the upper liquid chamber and the other end communicating with the lower liquid chamber. A liquid-filled mount structure, comprising: a recessed groove formed therein; and a liquid passage formed between the inner surface of the outer cylinder and the groove to connect the upper and lower liquid chambers.

前述の手段によれば、外筒に対して摺動する可動板の外周面に設けた凹溝が上 部液室と下部液室とを連通せしめて液体の流路を形成し、該流路がオリフィスと して機能する。このため、オリフィスサイズは一定に保たれ、狙いどおりの流通 抵抗が生じて確実な減衰特性が得られる。 According to the above-mentioned means, the concave groove provided on the outer peripheral surface of the movable plate that slides with respect to the outer cylinder makes the upper liquid chamber and the lower liquid chamber communicate with each other to form a liquid flow path, and the flow path Functions as an orifice. For this reason, the orifice size is kept constant, the desired flow resistance is generated, and reliable damping characteristics are obtained.

本考案による液体封入マウント構造の一実施例を図１ないし図６に基づいて説 明する。 An embodiment of the liquid-filled mount structure according to the present invention will be described with reference to FIGS.
【００１０】 図１は本考案による液体封入マウントの第１実施例を示す縦断面図（図２のＡ −Ａ断面）である。防振ゴム１は、内筒２と外壁板金３との間にゴムを加硫接着 して一体成形したもので、上下方向の中央部には液室となる空間が全周にわたっ て設けられている。この空間は、対向する位置に設けた一部の連結部１ａを残し て外周面を貫通している。そして、この空間には、防振ゴム１と一体に成形され 、内筒２側から全周にわたって水平に突出する仕切部４が設けられている。この 仕切部４は、空間の中心部よりやや上方に位置している。FIG. 1 is a vertical cross-sectional view (cross section AA of FIG. 2) showing a first embodiment of a liquid-filled mount according to the present invention. The anti-vibration rubber 1 is integrally formed by vulcanizing and adhering rubber between the inner cylinder 2 and the outer wall sheet metal 3, and a space serving as a liquid chamber is provided over the entire circumference in the central portion in the vertical direction. ing. This space penetrates the outer peripheral surface, leaving a part of the connecting portion 1a provided at the opposite position. Further, in this space, there is provided a partition portion 4 which is formed integrally with the anti-vibration rubber 1 and projects horizontally from the inner cylinder 2 side over the entire circumference. The partition portion 4 is located slightly above the center of the space.
【００１１】 上述した仕切部４に対し、内周面が略凹状に成形された可動板５が所定の間隙 をもって嵌合される。この可動板５は樹脂の成形品などが使用され、適所を高周 波溶接するなどして防振ゴム１に固定することにより、上記空間は、仕切部４及 び可動板５によって上部液室６と下部液室７とに分割される。A movable plate 5 whose inner peripheral surface is formed in a substantially concave shape is fitted to the partition 4 described above with a predetermined gap. This movable plate 5 is made of resin or the like, and is fixed to the vibration-proof rubber 1 by high-frequency welding at appropriate places, so that the above space is divided by the partition 4 and the movable plate 5 into the upper liquid chamber. 6 and the lower liquid chamber 7.
【００１２】 また、可動板５の外周面、すなわち組立てた状態で外筒８及び連結部１ａと摺 動する面に凹溝９を形成し、一端は上部液室６に連通せしめ、他端は下部液室７ に連通せしめる。この結果、図２（図１のＢ−Ｂ断面）に示す如く、可動板５の 外周面を半周して上部液室６及び下部液室７を連通せしめる液体の流路１０が形 成される。なお、図３（ａ），（ｂ）は可動板５の単品図で、（ａ）は平面図、 （ｂ）は正面図である。本実施例では、組立ての都合上二分割した分割可動板５ ａ，５ｂを組合せて使用しているが、二分割に限定されるものではない。しかし ながら、二分割とした場合には、同形状の分割可動板を２個用意し、一方を裏返 して組立てることが可能なため、部品の種類が少なくてすむ。Further, a concave groove 9 is formed on the outer peripheral surface of the movable plate 5, that is, a surface that slides with the outer cylinder 8 and the connecting portion 1a in the assembled state, one end of which communicates with the upper liquid chamber 6, and the other end of which has the other end. Communicate with the lower liquid chamber 7. As a result, as shown in FIG. 2 (B-B cross section of FIG. 1), a liquid flow path 10 is formed which half-circulates the outer peripheral surface of the movable plate 5 and connects the upper liquid chamber 6 and the lower liquid chamber 7. .. 3 (a) and 3 (b) are single-part views of the movable plate 5, (a) is a plan view, and (b) is a front view. In the present embodiment, the divided movable plates 5a and 5b divided into two are used in combination for the convenience of assembly, but the invention is not limited to two divisions. However, in the case of splitting into two, it is possible to prepare two split movable plates of the same shape and to assemble one by turning one over, so that the number of parts is small.
【００１３】 さて、上述した構成の流体封入マウントの組立てを簡単に説明すると、防振ゴ ム１、内筒２、外壁板金３及び仕切部４が一体成形された部品の空間部に、貫通 部の両側から各々１個の分割可動板５ａ，５ｂを差し込み、仕切部４との間に所 定の間隙を設け、高周波溶接などの方法により固定する。この状態まで組立てた ものを液室内に封入する液体、たとえばエチレングリコール系の液体中に入れ、 若干大径の外筒８に挿入してかしめる。こうして上部液室６、下部液室７及び流 路１０内などにはエチレングリコール系の液体が密閉封入される。なお、外壁板 金３の外周面に防振ゴム１と同時にシール部材１１を成形しておくと、かしめに よって外筒８及び外壁板金３の間で圧縮されて密着するのでシール性が向上する 。このシール部材１１に適当なピッチで凹凸やリップを設けると、シール性はさ らに向上する。The assembly of the fluid-filled mount having the above-described configuration will be briefly described below. The vibration isolating gum 1, the inner cylinder 2, the outer wall sheet metal 3 and the partition 4 are integrally formed in the space of the component, and the penetrating portion One of the movable movable plates 5a and 5b is inserted from both sides, and a predetermined gap is provided between the movable plate 5a and 5b and the partition 4 is fixed by a method such as high frequency welding. The assembly assembled up to this state is put into a liquid to be sealed in the liquid chamber, for example, an ethylene glycol-based liquid, and inserted into the outer cylinder 8 having a slightly larger diameter and caulked. In this way, ethylene glycol-based liquid is hermetically sealed in the upper liquid chamber 6, the lower liquid chamber 7, the flow path 10, and the like. If the sealing member 11 is formed on the outer peripheral surface of the outer wall sheet metal 3 at the same time as the anti-vibration rubber 1, the outer cylinder 8 and the outer wall sheet metal 3 are compressed by the caulking and adhere to each other, so that the sealing performance is improved. .. By providing the sealing member 11 with irregularities and lips at an appropriate pitch, the sealing property is further improved.
【００１４】 以下、本考案による液体封入マウント構造の作用を図４（ａ）〜（ｄ）の縦断 面図に基づいて説明する。（ａ）は完成した液体封入マウントの単品状態、すな わち無負荷時を示しており、上部液室６の容積は下部液室７より小さい。この液 体封入マウントを車両に取付け、静止（停車）時の負荷が作用している状態が（ ｂ）である。この状態では、内筒２に軸方向下向きの静止荷重が作用しており、 内筒２がｘ下がるのに伴って防振ゴム１も撓んで変形し、上部液室６及び下部液 室７の容積は略等しくなる。次に、（ｃ）及び（ｄ）は走行に伴う振動が作用し た場合を示すもので、（ｃ）はフルストローク時、（ｄ）はフルリバウンド時を 各々示している。すなわち（ｂ）の状態から軸方向下向きの振動入力が作用する と、内筒２が押し下げられてこれと一体の防振ゴム１を変形させ、下部液室７の 容積が減少するのと同時に上部液室６の容積が増加する。この容積変化に伴って 、液室内に封入された液体が流路１０を通って上部液室６側へ移動するので、内 筒２に作用した入力は、液体がオリフィスとして機能する流路１０を通る際の粘 性抵抗により大きな減衰が得られる。また、軸方向上向きの振動入力が作用した 時は流路１０に逆方向の流体の流れが生じるので、やはり流体の粘性抵抗によっ て大きな減衰が得られる。Hereinafter, the operation of the liquid-filled mount structure according to the present invention will be described with reference to the vertical sectional views of FIGS. (A) shows the completed liquid-filled mount as a single product, that is, when there is no load, and the volume of the upper liquid chamber 6 is smaller than that of the lower liquid chamber 7. This liquid enclosure mount is attached to the vehicle and the load is applied when the vehicle is stationary (stopped), as shown in (b). In this state, a static load is applied to the inner cylinder 2 in the axially downward direction. As the inner cylinder 2 is lowered by x, the antivibration rubber 1 is also bent and deformed, and the upper liquid chamber 6 and the lower liquid chamber 7 are The volumes are almost equal. Next, (c) and (d) show the case where the vibrations caused by running are applied. (C) shows the full stroke and (d) shows the full rebound. That is, when an axially downward vibration input is applied from the state of (b), the inner cylinder 2 is pushed down and the vibration damping rubber 1 integrated with this is deformed, so that the volume of the lower liquid chamber 7 decreases and at the same time the upper liquid chamber 7 decreases. The volume of the liquid chamber 6 increases. As the volume changes, the liquid enclosed in the liquid chamber moves to the upper liquid chamber 6 side through the flow passage 10, so that the input acting on the inner cylinder 2 passes through the flow passage 10 in which the liquid functions as an orifice. Greater damping is obtained due to viscous drag as it passes. In addition, when an axially upward vibration input is applied, a fluid flow in the opposite direction occurs in the flow path 10, and thus a large damping is also obtained by viscous resistance of the fluid.
【００１５】 このように、流体封入マウントの減衰特性はオリフィスの断面積や流体の粘性 の影響を受けるものであり、これらの値が設計値を維持できれば安定した特性が 得られる。そして、本考案のオリフィスは、外筒８の内面と、外筒８に沿って摺 動する可動板５に設けた凹溝９とで形成するようにしたので、水平方向の入力を 受けても断面積に変化はなく、また、液体の粘性は温度の影響を受けて変化はす るものの所望の値を容易に選択でき、従って、確実で安定した減衰特性の流体封 入マウントとなる。なおまた、仕切部４を防振ゴム体としたので、可動板５に働 く左右方向の力を緩和し、該可動板の作用を円滑にすることができる。As described above, the damping characteristic of the fluid-filled mount is influenced by the cross-sectional area of the orifice and the viscosity of the fluid. If these values can maintain the designed values, stable characteristics can be obtained. Further, since the orifice of the present invention is formed by the inner surface of the outer cylinder 8 and the concave groove 9 provided in the movable plate 5 which slides along the outer cylinder 8, even if a horizontal input is received. There is no change in the cross-sectional area, and the viscosity of the liquid changes under the influence of temperature, but the desired value can be easily selected, thus providing a fluid-sealed mount with a reliable and stable damping characteristic. In addition, since the partition portion 4 is made of the vibration-proof rubber body, the lateral force acting on the movable plate 5 can be alleviated and the operation of the movable plate can be made smooth.
【００１６】 なお、水平方向の入力に対しては、仕切部４と可動板５が共働して弾性ストッ パとして機能し、また、小さな振幅の振動入力に対しては、封入された液体が仕 切部４と可動板５との間に設けた間隙を流れることで、動的ばね定数の上昇を抑 えることができる。For horizontal input, the partition 4 and the movable plate 5 work together to function as an elastic stopper, and for vibration input of small amplitude, the enclosed liquid is By flowing through the gap provided between the partition 4 and the movable plate 5, it is possible to suppress the increase of the dynamic spring constant.
【００１７】 以上の実施例においては、仕切部４は防振ゴム１と一体成形したゴムの単体で あったが、たとえば可動板５の摺動部の抵抗が大きくなるような条件で使用する ような場合などには、第２実施例として図５に示した如く、仕切部４の内部にリ ング状の補助金具１２を入れてもよい。この補助金具１２は内筒２の外周面に溶 接などで予め固定しておくもので、該補助金具を第１実施例と同様にゴムを加硫 接着して覆うことにより、高剛性の仕切部４を形成することができ、従って、大 きな摺動抵抗にも十分対応できるようになる。In the above-described embodiments, the partition portion 4 is a single piece of rubber integrally molded with the anti-vibration rubber 1. However, the partition portion 4 may be used under such a condition that the sliding portion of the movable plate 5 has a large resistance. In such a case, as shown in FIG. 5 as the second embodiment, a ring-shaped auxiliary metal fitting 12 may be placed inside the partition portion 4. The auxiliary metal fitting 12 is fixed to the outer peripheral surface of the inner cylinder 2 in advance by welding or the like. By covering the auxiliary metal fitting by vulcanizing and adhering rubber as in the first embodiment, a high-rigidity partition is provided. The portion 4 can be formed, and therefore, it is possible to sufficiently cope with a large sliding resistance.
【００１８】 さらに、高剛性の仕切部４は、第３実施例として図６に示した如く、比較的低 硬度のゴムを加硫接着した防振ゴム１に対して、高硬度のゴムを別体に、あるい は部分的に加硫接着して形成することも可能である。Further, as shown in FIG. 6 as the third embodiment, the high-rigidity partitioning section 4 separates a rubber having a high hardness from a vibration-proof rubber 1 obtained by vulcanizing and adhering a rubber having a relatively low hardness. It can also be formed by vulcanization adhesion to the body or partly.
【００１９】[0019]
前述した本考案の流体封入マウント構造によれば、上下の液室を連通する流路 （オリフィス）の断面積が入力を受けても変化しないため、設定した減衰特性を 確実にかつ安定して得ることができる。また、仕切板に高剛性が要求される場合 には、仕切部内に補強金具を入れたり、あるいは、ゴムの硬度を使い分けること により容易に対応できるので、設計上の自由度も高い。 According to the above-described fluid-filled mount structure of the present invention, the cross-sectional area of the flow path (orifice) that connects the upper and lower liquid chambers does not change even when input is received, so the set damping characteristics can be obtained reliably and stably. be able to. In addition, when high rigidity is required for the partition plate, it is possible to easily deal with it by installing reinforcing metal fittings in the partition part or by using different hardness of rubber, so there is a high degree of freedom in design.
