【従来の技術】[Prior Art]

現在、乗用車系の自動車のフレームとデファレンシャルとの取付はラバータイ プの防振マウントを介設してなされているが、プロペラシャフトの回転変動があ るためデファレンシャルの振動が問題となっている。 Currently, the frame and differential of a passenger car system are mounted via a rubber-type anti-vibration mount, but the vibration of the differential poses a problem due to fluctuations in the rotation of the propeller shaft.

【0003】 そこで近年に至り、上記フレームとデファレンシャルとの間に介設される防振 マウントとして減衰性能に優れる液封入式のものが用いられるようになり、かか る液封入防振マウントとしては従来、例えば図6,図7に示すように、軸孔(1 a)に挿通した取付ボルト等を介して自動車のデフ側に固定される内筒(1)と 、該内筒を間隔をあけて取り囲み、自動車のフレーム側に固定される外筒(2) と、これら内外筒間に固着されたゴム弾性体からなる防振基体(3)と、該防振 基体(3)内部に設けられた液室(4a),(4b)とを有したものが周知であ る。Therefore, in recent years, a liquid filled type vibration damping mount excellent in damping performance has been used as a vibration damping mount interposed between the frame and the differential, and such a liquid filled vibration damping mount is used. Conventionally, as shown in, for example, FIGS. 6 and 7, an inner cylinder (1) fixed to the differential side of an automobile through a mounting bolt or the like inserted through a shaft hole (1a) and the inner cylinder are spaced from each other. An outer cylinder (2) which is surrounded by a frame and fixed to the frame side of the automobile, a vibration-damping base (3) made of a rubber elastic body fixed between the inner and outer cylinders, and provided inside the vibration-damping base (3). It is well known that the liquid chambers (4a) and (4b) are provided.

【0004】 上記2つの液室(4a),(4b)は図示しないオリフィスにて連通すると共 に、下の液室(4b)には、マウントに所定値以上の過負荷がかかった際に、内 筒(1)と外筒(2)とに挟まれることにより液室(4b)の径方向の変形を規 制するストッパー(S)が設けられている。該ストッパー(S)はその基部が内 筒(1)に溶接され、またその表面には防振基体(3)のゴムによってカバーゴ ム(10)が設けられている。The two liquid chambers (4a) and (4b) communicate with each other through an orifice (not shown), and the lower liquid chamber (4b) is exposed to an overload of a predetermined value or more when the mount is overloaded. A stopper (S) is provided which controls the radial deformation of the liquid chamber (4b) by being sandwiched between the inner cylinder (1) and the outer cylinder (2). The stopper (S) has a base portion welded to the inner cylinder (1), and a cover rubber (10) is provided on the surface of the stopper (S) by the rubber of the vibration isolating base (3).

【考案が解決しようとする課題】[Problems to be solved by the device]

ところで、かかる従来の液封入防振マウントにあっては、これを自動車のデフ ァレンシャル等の支持部に装着,使用するときは、走行中に伝わる振動は防振基 体(3)に設けた空洞(9),(9)や液体がオリフィス(図示せず)を介して 流動する液室(4a),(4b)の容積変化に伴い変形する防振基体(3)で絶 縁させ、他方デファレンシャルギヤ等から伝わる振動は共振して減衰特性を発揮 する液体で減衰させ得るにしても、前記ストッパー(S)が内筒(1)に固定さ れていることから、内筒の振動を直接封入液に伝達して得られる減衰レベルの低 下を招き、またこの状態でストッパー(S)を大きくすると防振基体(3)のゴ ム壁に干渉する度合いが高まり防振基体の耐久性を低下させることも考えられ、 更にストッパー(S)を覆う前記カバーゴム(10)は防振基体(3)の加硫に より設けられるものであるから、ストッパー専用の衝撃性のよいゴムを使用する ことができない等の問題点を有している。 By the way, in such a conventional liquid-filled anti-vibration mount, when it is mounted and used on a support part such as a differential of an automobile, vibration transmitted during traveling is a cavity provided in the anti-vibration base (3). The (9) and (9) and the liquid flow through the orifice (not shown), and the liquid isolation chambers (4a) and (4b) are deformed with the volume change of the vibration isolating substrate (3), and the differential is used. Although the vibration transmitted from the gear etc. can be damped by the liquid that resonates and exhibits damping characteristics, since the stopper (S) is fixed to the inner cylinder (1), the vibration of the inner cylinder is directly enclosed. If the stopper (S) is increased in this state, the damping level obtained by transmitting it to the liquid is lowered, and the degree of interference with the rubber wall of the vibration isolation base (3) increases and the durability of the vibration isolation base deteriorates. It is also possible to make it, and further stopper Since the cover rubber (10) covering S) is provided by vulcanization of the vibration-proof substrate (3), it has a problem that it is impossible to use a rubber having a good impact property exclusively for the stopper. ing.

【0006】 本考案は、このような問題に対処してなされたものであり、従前の液封入防振 マウントの特にストッパーの取付構造に新規な構成を見出すことにより、減衰性 能や防振マウントの耐久性を向上させると共に、ストッパーの当たり面に適正な カバーゴムを装着することを目的とするものである。The present invention has been made in response to such a problem, and by finding a new structure in the conventional liquid-filled anti-vibration mount, particularly the mounting structure of the stopper, the damping performance and the anti-vibration mount can be obtained. It is intended to improve the durability of the stopper and to mount an appropriate cover rubber on the contact surface of the stopper.

【課題を解決するための手段】[Means for Solving the Problems]

即ち、上記目的に適合しうる本考案ストッパー付液封入防振マウントの特徴は 、内筒とこれを取り囲む外筒との間に、ゴム弾性体からなる防振基体を該基体内 部に液室を設けて固着すると共に、該液室内に、マウントの過負荷時に上記内・ 外筒間に挟まれることにより液室の径方向の変形を規制するストッパーを設けた ストッパー付液封入防振マウントにおいて、上記ストッパーにその両側部からマ ウントの接線方向または軸方向に延びる支持部材を設けると共に、該支持部材両 端部をマウントの周方向又は軸方向における液室の対向壁部に夫々設けた凹部に 嵌合し、かつ上記ストッパーの当たり面が前記内筒及び外筒の夫々に対し所要間 隙を有するよう該ストッパーを支持固定せしめたことにある。 なお、ここでいう接線方向とは、必ずしも直線を意味するものではなく、円弧 状に湾曲したものも含むものである。 That is, the feature of the liquid-filled anti-vibration mount with stopper according to the present invention, which can be adapted to the above-mentioned purpose, is that a vibration-damping base body made of a rubber elastic body is provided between the inner cylinder and the outer cylinder surrounding the inner cylinder. A liquid-filled anti-vibration mount with a stopper, which is provided with a stopper that restricts radial deformation of the liquid chamber by being sandwiched between the inner and outer cylinders when the mount is overloaded A recess provided with a support member extending from both sides of the stopper in the tangential direction or the axial direction of the mount, and both ends of the support member provided in the opposing wall of the liquid chamber in the circumferential direction or the axial direction of the mount, respectively. The stopper is supported and fixed so that the contact surface of the stopper has a required clearance with respect to each of the inner cylinder and the outer cylinder. Note that the tangential direction here does not necessarily mean a straight line, but includes one curved in an arc shape.

【作用】[Action]

上記構成を有する本考案ストッパー付液封入防振マウントにあっては、ストッ パーが支持部材により防振基体のゴム壁に支持され、ストッパー自体は内筒及び 外筒の夫々に対し非接触の状態であることから、従来のようにマウントの減衰性 能や防振基体の耐久性に何ら影響を及ぼすことがなく、ストッパーがない防振マ ウントと同等の減衰性能と耐久性とを確保することが可能である。 また、ストッパーが独立した別部品となることから、従来はその当たり面まで 防振基体の加硫ゴムで覆われていたのに対し、上記ゴムとは異なる衝撃性に優れ た適正なゴムを使用することができ、マウントの過負荷時の信頼性をさらに向上 させることが可能となる。 In the liquid-filled anti-vibration mount with stopper having the above structure, the stopper is supported by the support member on the rubber wall of the anti-vibration substrate, and the stopper itself is in non-contact with the inner cylinder and the outer cylinder. Therefore, the damping performance of the mount and the durability of the anti-vibration base are not affected as before, and the same damping performance and durability as the anti-vibration mount without a stopper must be secured. Is possible. In addition, since the stopper is a separate component, the contact surface of the stopper was conventionally covered with the vulcanized rubber of the anti-vibration substrate, but an appropriate rubber different from the above rubber with excellent impact resistance was used. It is possible to further improve the reliability when the mount is overloaded.

以下更に添付図面を参照して本考案実施例のストッパー付液封入防振マウント を説明する。 A liquid-filled anti-vibration mount with a stopper according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

【0010】 図1は本考案マウントの1例を示す要部断面説明図であり、このマウントは、 内筒(1)とこれを取り囲む外筒(2)との間に、ゴム弾性体からなる防振基体 (3)を固着してなり、該防振基体(3)にオリフィス(図示せず)にて互いに 連通する液室(4a),(4b)を設けると共に、該基体(3)に空洞(9), (9)を形成し、さらに上記下側の液室(4b)内に、マウントの過負荷時に上 記内・外筒(1),(2)間に挟まれることにより液室(4b)の径方向への変 形を規制するストッパー(S)を設けた構成を有している。FIG. 1 is an explanatory cross-sectional view of a main part showing an example of a mount of the present invention. This mount is made of a rubber elastic body between an inner cylinder (1) and an outer cylinder (2) surrounding the inner cylinder (1). The vibration-proof substrate (3) is fixed, and the vibration-proof substrate (3) is provided with liquid chambers (4a), (4b) communicating with each other through an orifice (not shown). By forming cavities (9) and (9) and further sandwiching them in the lower liquid chamber (4b) between the inner and outer cylinders (1) and (2) when the mount is overloaded, It has a configuration in which a stopper (S) for restricting the radial deformation of the chamber (4b) is provided.

【0011】 ストッパー(S)はこの例では金属よりなる円柱状を呈し、その両側部には図 2にも示すように、マウントの周方向または接線方向に延びる金属性の支持部材 (5)が設けられると共に、該支持部材(5)の両端部は特に図2に示すように 、液室(4b)の周方向に対向する壁部(6),(6)に夫々設けた凹部(7) ,(7)に嵌合され、上記ストッパー(S)は、その当たり面(8),(8)が 前記内筒(1)及び外筒(2)の夫々に対し所要間隙を有するように上記支持部 材(5)により支持固定されている。また、ストッパー(S)の上記当たり面( 8),(8)には夫々、防振基体(3)を構成するゴムとは別の、より衝撃性に 優れたカバーゴム(10)が加硫接着されている。このカバーゴム(10)は上 記のようにストッパー(S)の当たり面(8),(8)にのみ設けてもよいが、 ストッパー(S)全体を被覆させて設けるようしてもよい。In this example, the stopper (S) has a cylindrical shape made of metal, and a metal support member (5) extending in the circumferential direction or the tangential direction of the mount is provided on both sides of the stopper (S) as shown in FIG. As shown in FIG. 2, the both ends of the supporting member (5) are provided in the recesses (7) respectively provided in the wall portions (6), (6) facing each other in the circumferential direction of the liquid chamber (4b). , (7), and the stopper (S) has the contact surfaces (8), (8) having the required clearances with respect to the inner cylinder (1) and the outer cylinder (2), respectively. It is supported and fixed by the support member (5). Further, a cover rubber (10), which is different from the rubber constituting the anti-vibration substrate (3) and is superior in impact resistance, is vulcanized on each of the contact surfaces (8) and (8) of the stopper (S). It is glued. The cover rubber (10) may be provided only on the contact surfaces (8) and (8) of the stopper (S) as described above, but may be provided by covering the entire stopper (S).

【0012】 他方、液室(4b)の壁部(6)に設けた上記凹部(7)は、通常図3に示す 如く、凸部(K1 )を有する型(K)により成形されるが、中間金具(11)が ある場合でも、同図矢印に示す型(K)の引き抜き方向で上記金具(11)と型 の凸部(K1 )とがぶつからなければアンダーカットでも加硫が可能である。ま た、ストッパー(S)の支持部材(5)としては、図4,図5に示すような板状 や丸棒、その他の形状が作用されるため、上記凹部(7)はこれらを若干強制的 に嵌合させる形状が望ましい。On the other hand, the concave portion (7) provided on the wall portion (6) of the liquid chamber (4b) is usually formed by a mold (K) having a convex portion (K 1 ) as shown in FIG. Even if there is an intermediate metal fitting (11), it is possible to vulcanize even undercut if the metal fitting (11) and the convex part (K 1 ) of the mold do not collide with each other in the drawing direction of the mold (K) shown by the arrow in the figure. Is. Further, as the supporting member (5) of the stopper (S), a plate-like shape, a round bar, or another shape as shown in FIGS. 4 and 5 acts, so that the recess (7) slightly forces these. It is desirable to have a shape that allows proper fitting.

【0013】 以上の構成を有する本考案実施例の防振マウントにおいては、ストッパー(S )が支持部材(5)により防振基体(3)のゴム壁部(6)に支持され、ストッ パー(S)自体は内筒(1)及び外筒(2)の夫々に対し非接触の状態であるこ とから、従来のようにマウントの減衰性能や防振基体の耐久性に何ら影響を及ぼ すことがなく、ストッパーがない防振マウントと同等の減衰性能と耐久性とを確 保することが可能である。 また、ストッパー(S)が独立した別部品となることから、従来はその当たり 面(8)まで防振基体(3)の加硫ゴムで覆われていたのに対し、上記ゴムとは 異なる衝撃性に優れた適正なゴムをカバーゴム(10)として使用することがで き、マウントの過負荷時の信頼性をさらに向上させることが可能となる。In the vibration-proof mount of the embodiment of the present invention having the above configuration, the stopper (S) is supported by the support member (5) on the rubber wall portion (6) of the vibration-proof base (3), and the stopper (S) is Since S) itself is in non-contact with the inner cylinder (1) and the outer cylinder (2) respectively, it has no influence on the damping performance of the mount and the durability of the anti-vibration substrate as in the past. It is possible to ensure the same damping performance and durability as the anti-vibration mount with no stopper. In addition, since the stopper (S) is a separate and independent part, hitherto the contact surface (8) was conventionally covered with the vulcanized rubber of the anti-vibration substrate (3), but the impact different from the above rubber It is possible to use a proper rubber having excellent properties as the cover rubber (10), and it is possible to further improve the reliability when the mount is overloaded.

Even if the stopper (S) is removed from the recesses (7) and (7), the stopper (S) is sandwiched between the inner cylinder (1) and the outer cylinder (2), so that the stopper (S) is in the liquid chamber (4b). Therefore, when the liquid chamber (4b) is restored, both ends of the support member (5) are fitted into the recesses (7) and (7) as they were originally.

【考案の効果】[Effect of the device]

以上説明したように、本考案のストッパー付液封入防振マウントは、液室内に 、マウント上の過負荷時に内・外筒間に挟まれることにより該液室の径方向への 変形を規制するストッパーを設けた防振マウントにおいて、上記ストッパーにそ の両側部からマウントの接線方向または軸方向に延びる支持部材を設けると共に 、該支持部材両端部をマウントの周方向又は軸方向における液室の対向壁部に夫 々設けた凹部に嵌合し、かつ上記ストッパーの当たり面が前記内筒及び外筒の夫 々に対し所要間隙を有するよう該ストッパーを支持固定せしめたものであり、ス トッパーが支持部材により防振基体のゴム壁に支持され、ストッパー自体は内筒 及び外筒の夫々に対し非接触の状態であることから、従来例のようにマウントの 減衰性能や防振基体の耐久性に何ら影響を及ぼすことがなく、ストッパーがない 防振マウントと同等の減衰性能と耐久性とを確保することが可能であり、また、 ストッパーが独立した別部品となることから、従来ではその当たり面まで防振基 体の加硫ゴムで覆われていたのに対し、上記ゴムとは異なる衝撃性に優れた適正 なゴムを使用することができ、マウントの過負荷時の信頼性をさらに向上させる ことが可能であるとの顕著な効果を奏するものである。 そしてさらに、上記過負荷時に、液室の壁部がマウントの周方向に拡がって支 持部材が壁部の凹部から外れたとしても、ストッパーは内筒と外筒とに挟まれて いることから該ストッパーの液室内の相対位置は変わらず、従って、液室が復元 する際には、上記支持部材は元のようにその両端部が上記凹部に嵌合するとの作 用効果も有するものである。 As described above, the liquid-filled anti-vibration mount with stopper of the present invention restricts the radial deformation of the liquid chamber by being sandwiched between the inner and outer cylinders when the mount is overloaded. In an anti-vibration mount having a stopper, the stopper is provided with a support member extending from both sides thereof in a tangential direction or an axial direction of the mount, and both end portions of the support member are opposed to a liquid chamber in a circumferential direction or an axial direction of the mount. The stopper is supported and fixed so that the stopper fits in the recesses respectively provided in the walls and the contact surface of the stopper has a required gap with respect to each of the inner cylinder and the outer cylinder. The support member is supported by the rubber wall of the anti-vibration substrate, and the stopper itself is in non-contact with the inner cylinder and the outer cylinder. It does not affect the durability of the body, it is possible to secure the same damping performance and durability as the anti-vibration mount without a stopper, and because the stopper is a separate and independent part, In the past, the contact surface was covered with the vulcanized rubber of the anti-vibration base, but it is possible to use a proper rubber with excellent impact resistance different from the above rubber, and the reliability when the mount is overloaded It has a remarkable effect that it is possible to further improve the property. Further, even if the wall of the liquid chamber expands in the circumferential direction of the mount and the supporting member comes off the recess of the wall at the time of the above-mentioned overload, the stopper is sandwiched between the inner cylinder and the outer cylinder. The relative position of the stopper in the liquid chamber does not change. Therefore, when the liquid chamber is restored, both ends of the support member are fitted in the recesses as they were originally. ..
