Description

本発明は、例えば自動車の内燃機関におけるシリンダブロック及びチェーンケースとシリンダヘッドなどのような、三つの部材の組み合わせにより形成される三面合わせ部をシールするために用いられるガスケットに関する。   The present invention relates to a gasket used for sealing a three-faced joint formed by a combination of three members such as a cylinder block and a chain case and a cylinder head in an internal combustion engine of an automobile.

自動車の内燃機関においては、シリンダブロックとシリンダヘッドとの合わせ面間がシリンダヘッドガスケットによって密封されている。この種のシリンダヘッドガスケットは、例えば表面に薄い合成ゴム層を塗布した薄いステンレスばね鋼鈑等、適当な弾性を有する金属板からなるものであって、シリンダブロックの各燃焼室と対応する複数のボアや、オイルを通すための油穴やエンジン冷却水を通すための冷却水穴と対応する複数の弾性体保持穴が開設され、これらの弾性体保持穴の周囲に沿って、それぞれシール用のビードが形成された構造を有する。   In an internal combustion engine of an automobile, a space between the mating surfaces of a cylinder block and a cylinder head is sealed with a cylinder head gasket. This type of cylinder head gasket is made of a metal plate having appropriate elasticity, such as a thin stainless spring steel plate coated with a thin synthetic rubber layer on the surface, and has a plurality of cylinder chambers corresponding to each combustion chamber. A plurality of elastic body holding holes corresponding to bores, oil holes for passing oil and cooling water holes for passing engine cooling water are established, and each of the elastic body holding holes is sealed along the periphery of these elastic body holding holes. It has a structure in which a bead is formed.

また、シリンダブロック及びシリンダヘッドとチェーンケースとの三面合わせ部では、寸法の僅かな誤差や熱膨張差などによって、シリンダブロック、シリンダヘッド、チェーンケース及びシリンダヘッドガスケットの間で段差を発生するため、このような段差に起因する部分的な面圧不足を生じ、シール性が損なわれやすい。そこで従来、シリンダヘッドガスケットにおける前記三面合わせ部と対応する部分に弾性体を配置することによって、前記段差を吸収してシール性を確保するようにしたものや（下記の特許文献１参照）、シリンダヘッドガスケットにおける前記三面合わせ部と対応する部分に弾性体を配置すると共に、この弾性体に液状ガスケット（液体パッキン）を塗布するもの（下記の特許文献２参照）などが知られている。   In addition, in the three-surface mating part between the cylinder block and cylinder head and the chain case, a step is generated between the cylinder block, cylinder head, chain case and cylinder head gasket due to a slight error in dimensions or a difference in thermal expansion. A partial surface pressure deficiency due to such a step is generated, and the sealing performance is easily impaired. Therefore, conventionally, an elastic body is disposed at a portion corresponding to the three-surface mating portion in the cylinder head gasket so as to absorb the step and ensure sealing performance (see Patent Document 1 below), cylinder There is known a structure in which an elastic body is disposed at a portion corresponding to the three-surface mating portion in the head gasket and a liquid gasket (liquid packing) is applied to the elastic body (see Patent Document 2 below).

特開平１０−２９２８６５号公報JP-A-10-292865 特開２００２−７１０２６号公報JP 2002-71026 A

しかしながら、特許文献１に記載のようなガスケットは、部材間の段差を吸収することにおいて有効ではあるが、段差を吸収する弾性体が、予めガスケットのフルビードによる凹部に未加硫のゴム材を塗布し、このゴム材がエンジンの熱で加硫することによって設けられたものであるため、前記フルビードによる凹部内の弾性体の充填量が少なく、このため段差に十分に追随して隙間を埋めて確実にシールすることが困難な場合がある。   However, the gasket as described in Patent Document 1 is effective in absorbing a step between members, but an elastic body that absorbs the step applies an unvulcanized rubber material in advance to a recess by a full bead of the gasket. However, since this rubber material is provided by vulcanizing with the heat of the engine, the filling amount of the elastic body in the concave portion by the full beads is small, so that the gap is sufficiently filled by following the step. It may be difficult to seal reliably.

また、特許文献２に記載のようなガスケットは、複数の板を積層したガスケットにおける前記三面合わせ部と対応する部分に弾性体を配置すると共に、この弾性体に液体パッキンを塗布した構成となっているため、部品数が多く、しかも弾性体を保持する嵌合穴が非貫通であるため、弾性体の配置や液体パッキンの塗布量などを確認することが困難であるといった問題がある。   In addition, the gasket as described in Patent Document 2 has a configuration in which an elastic body is disposed in a portion corresponding to the three-surface mating portion in a gasket in which a plurality of plates are laminated, and liquid packing is applied to the elastic body. Therefore, since there are many parts and the fitting hole holding an elastic body is non-penetrating, there exists a problem that it is difficult to confirm the arrangement | positioning of an elastic body, the coating amount of liquid packing, etc.

本発明は、以上のような点に鑑みてなされたものであって、その技術的課題は、互いに結合された三部材の間の三面合せ部における優れたシール性を奏することの可能なガスケットを提供することにある。   The present invention has been made in view of the above points, and its technical problem is to provide a gasket capable of exhibiting excellent sealing performance at a three-sided joint portion between three members joined together. It is to provide.

上述した技術的課題を有効に解決するための手段として、請求項１の発明に係る三面合わせ部用ガスケットは、第一の部材及び第二の部材と第三の部材との間に介在される板状のガスケット本体及びゴム状弾性体からなり、前記ガスケット本体は、装着状態において前記第一の部材と前記第二の部材の境界を跨ぐように延びる複数のビードが形成されると共に、隣接するビードの間に、装着状態において前記境界を跨ぐ位置に弾性体保持穴が貫通形成されたものであり、前記ゴム状弾性体は、前記弾性体保持穴に保持され、前記第一の部材、第二の部材及び第三の部材に密接されるものである。   As means for effectively solving the technical problem described above, the gasket for a three-sided joint according to the invention of claim 1 is interposed between the first member and the second member and the third member. The gasket main body is composed of a plate-like gasket main body and a rubber-like elastic body, and the gasket main body is adjacent to each other with a plurality of beads extending across the boundary between the first member and the second member in the mounted state. Between the beads, an elastic body holding hole is formed at a position across the boundary in the mounted state, and the rubber-like elastic body is held in the elastic body holding hole, and the first member, It is in close contact with the second member and the third member.

請求項２の発明に係る三面合わせ部用ガスケットは、請求項１に記載の構成において、隣接するビードの互いの間隔が、弾性体保持穴の両側を通る部分で広くなっているものである。   According to a second aspect of the present invention, there is provided the gasket for a three-surface mating portion according to the first aspect, wherein an interval between adjacent beads is widened at a portion passing through both sides of the elastic body holding hole.

請求項３の発明に係る三面合わせ部用ガスケットは、請求項１又は２に記載の構成において、ゴム状弾性体が液状ガスケットの硬化物からなるものである。   The gasket for a three-surface mating portion according to the invention of claim 3 is the structure according to claim 1 or 2, wherein the rubber-like elastic body is a cured product of a liquid gasket.

本発明に係る三面合わせ部用ガスケットによれば、ガスケット本体の互いに隣接するビードの間に開設された弾性体保持穴にゴム状弾性体が充填された構成としたため、部品数が少なくなると共に、ゴム状弾性体の保持量を多くして三部材間の三面合わせ部の段差を有効に吸収することができ、しかもゴム状弾性体を保持する弾性体保持穴がガスケット本体を貫通していることによって、このゴム状弾性体が第一の部材、第二の部材及び第三の部材に密接されるので、優れたシール性を奏することができる。   According to the gasket for a three-sided joint portion according to the present invention, since the elastic body holding hole opened between the beads adjacent to each other of the gasket body is filled with the rubber-like elastic body, the number of parts is reduced, The holding amount of the rubber-like elastic body can be increased to effectively absorb the step of the three-faced joint between the three members, and the elastic body holding hole for holding the rubber-like elastic body must penetrate the gasket body By this, since this rubber-like elastic body is brought into close contact with the first member, the second member, and the third member, excellent sealing performance can be achieved.

また、隣接するビードの互いの間隔を、弾性体保持穴の両側を通る部分で広くすることによって、ゴム状弾性体の保持量を一層多くすることができ、ゴム状弾性体が液状ガスケットの硬化物からなるものとすれば、この液状ガスケットを三部材間の三面合わせ部によくいきわたった状態として硬化させることができるので、シール性を一層高めることができる。   Further, by widening the interval between adjacent beads at the portions passing through both sides of the elastic body holding hole, it is possible to further increase the holding amount of the rubber-like elastic body, and the rubber-like elastic body cures the liquid gasket. If it consists of a thing, since this liquid gasket can be hardened as the state which spread | circulated well on the three-surface joining part between three members, a sealing performance can be improved further.

以下、本発明に係る三面合わせ部用ガスケットの好ましい実施の形態について、図面を参照しながら詳細に説明する。   Hereinafter, preferred embodiments of the gasket for a three-surface mating portion according to the present invention will be described in detail with reference to the drawings.

まず図１〜図５に示す第一の実施の形態としてのガスケットは、自動車の内燃機関におけるシリンダブロック及びチェーンケースとシリンダヘッドなどのような三つの部材（図４及び図５に示す第一の部材１０１、第二の部材１０２及び第三の部材１０３）の組み合わせにより形成される三面合わせ部をシールするもので、ガスケット本体１と、このガスケット本体１に保持されたゴム状弾性体２からなる。   First, a gasket as a first embodiment shown in FIGS. 1 to 5 includes three members such as a cylinder block, a chain case, and a cylinder head in an internal combustion engine of an automobile (the first embodiment shown in FIGS. 4 and 5). This seals a three-sided joint formed by a combination of the member 101, the second member 102, and the third member 103), and comprises a gasket body 1 and a rubber-like elastic body 2 held by the gasket body 1. .

ガスケット本体１は図１、図２及び図３に示すように、環状に連続した板状の金属からなるものであって、内周側及び外周側のフルビードからなる二条のビード１１，１１が周設され、この互いに隣接して延びるビード１１，１１の間に、ビード１１，１１の延長方向へ細長い長孔状の一対の弾性体保持穴１２と、ボルト挿通穴などの複数の円形穴１３が開設されている。そして、ビード１１，１１や弾性体保持穴１２及び円形穴１３以外の部分は、平坦な平板部１４となっている。   As shown in FIGS. 1, 2, and 3, the gasket body 1 is made of a plate-like metal that is continuous in an annular shape, and has two strips of beads 11, 11 made of inner and outer full beads. Between the beads 11 and 11 extending adjacent to each other, there are a pair of elastic hole holding holes 12 elongated in the extending direction of the beads 11 and 11 and a plurality of circular holes 13 such as bolt insertion holes. It has been established. The portions other than the beads 11, 11, the elastic body holding holes 12, and the circular holes 13 are flat plate portions 14.

ガスケット本体１のビード１１，１１は、図３に示すように円弧面状の山形に打ち出し形成されたものであって、弾性体保持穴１２や円形穴１３の両側を通る部分では、ビード１１，１１の互いの間隔が広くなっている。   As shown in FIG. 3, the beads 11, 11 of the gasket body 1 are formed by punching into an arcuate chevron, and the beads 11, 11 pass through both sides of the elastic body holding hole 12 and the circular hole 13. The space | interval of 11 mutually becomes large.

図１に示す二点鎖線１００は図４及び図５に示す第一の部材１０１と第二の部材１０２の境界（合わせ面）を示しており、ガスケット本体１に開設された一対の弾性体保持穴１２は、装着状態において前記境界１００を跨ぐ位置、すなわち第一の部材１０１と第二の部材１０２に跨がる位置に開設されている。   A two-dot chain line 100 shown in FIG. 1 indicates a boundary (mating surface) between the first member 101 and the second member 102 shown in FIGS. 4 and 5, and holds a pair of elastic bodies provided in the gasket body 1. The hole 12 is opened at a position straddling the boundary 100 in the mounted state, that is, a position straddling the first member 101 and the second member 102.

図４及び図５に示すゴム状弾性体２は、ＦＩＰＧ（Formed-in-Place Gasket)などの液状ガスケットの硬化物からなるものであって、すなわち前記液状ガスケットが高粘度の液状すなわち未加硫状態でガスケット本体１の弾性体保持穴１２及びその周囲に塗布され、加硫硬化することによって前記弾性体保持穴１２保持され、第一の部材１０１、第二の部材１０２及び第三の部材１０３に密接されるものである。   The rubber-like elastic body 2 shown in FIGS. 4 and 5 is made of a cured product of a liquid gasket such as FIPG (Formed-in-Place Gasket), that is, the liquid gasket is a highly viscous liquid, that is, unvulcanized. In this state, the elastic body holding hole 12 is applied to and around the elastic body holding hole 12 and vulcanized and cured to hold the elastic body holding hole 12, and the first member 101, the second member 102, and the third member 103. Is closely related to

以上のように構成された三面合わせ部用ガスケットは、ガスケット本体１とこれに開設された弾性体保持穴１２に保持されたゴム状弾性体２からなるものであるため、部品数が少なく、安価に提供することができる。   The gasket for the three-surface mating portion configured as described above is composed of the gasket main body 1 and the rubber-like elastic body 2 held in the elastic body holding hole 12 provided in the gasket main body 1. Can be provided.

この三面合わせ部用ガスケットは、例えば図４及び図５に示すように、第一の部材１０１及び第二の部材１０２と、その双方と対向するように接合される第三の部材１０３の間に介装されることによって、これら第一の部材１０１、第二の部材１０２及び第三の部材１０３による三面合わせ部をシールするものである。   As shown in FIGS. 4 and 5, for example, the gasket for the three-surface mating portion is provided between the first member 101 and the second member 102 and the third member 103 joined so as to face both of them. By being interposed, the three-surface mating portion formed by the first member 101, the second member 102, and the third member 103 is sealed.

そしてこの装着状態では、ガスケット本体１のビード１１，１１が、第三の部材１０３における第一の部材１０１及び第二の部材１０２との対向面に、適当な変形を受けた状態で密接されると共に、ガスケット本体１の平板部１４におけるビード１１の突出方向と反対側の面が、第一の部材１０１及び第二の部材１０２に跨がって密接され、ガスケット本体１の弾性体保持穴１２に保持されたゴム状弾性体２は、第一の部材１０１と第二の部材１０２の境界１００を跨ぐ位置で互いの間隔が広がっているビード１１，１１の間で、第一の部材１０１及び第二の部材１０２と第三の部材１０３に密接されている。   In this mounted state, the beads 11, 11 of the gasket body 1 are brought into close contact with the first member 101 and the second member 102 of the third member 103 facing the first member 101 and the second member 102 in an appropriately deformed state. At the same time, the surface of the flat plate portion 14 of the gasket body 1 opposite to the protruding direction of the beads 11 is in close contact with the first member 101 and the second member 102, and the elastic body holding hole 12 of the gasket body 1. The rubber-like elastic body 2 held by the first member 101 and the bead 11, 11 that are spaced apart from each other at a position across the boundary 100 between the first member 101 and the second member 102. It is in close contact with the second member 102 and the third member 103.

ここでゴム状弾性体２は、先に説明したように、予めＦＩＰＧなどの液状ガスケットを未加硫の高粘度の液状のままで、ガスケット本体１の弾性体保持穴１２及びその周囲、すなわち図２に破線で示す部分に塗布してから、このガスケット本体１を第一の部材１０１及び第二の部材１０２と、第三の部材１０３との間に介装し、内燃機関からの熱で前記液状ガスケットを加硫硬化させたものである。   Here, as described above, the rubber-like elastic body 2 is a liquid gasket such as FIPG in the form of an unvulcanized high-viscosity liquid, and the elastic body holding hole 12 of the gasket body 1 and its surroundings, that is, FIG. 2, the gasket body 1 is interposed between the first member 101 and the second member 102 and the third member 103, and is heated by the heat from the internal combustion engine. A liquid gasket is vulcanized and cured.

このとき、ガスケット本体１における液状ガスケットの塗布個所には弾性体保持穴１２が開設されているので、塗布量が充分であるかを確認しながら液状ガスケットを塗布することができる。   At this time, since the elastic body holding hole 12 is opened at the application portion of the liquid gasket in the gasket body 1, the liquid gasket can be applied while confirming whether the application amount is sufficient.

そして、液状ガスケットを塗布したガスケット本体１を、第一の部材１０１及び第二の部材１０２と、第三の部材１０３との間に介装してこれら第一の部材１０１、第二の部材１０２及び第三の部材１０３を締結する過程で、ガスケット本体１が、ビード１１，１１がつぶされるような変形を受けることによって、前記液状ガスケットが第一の部材１０１及び第二の部材１０２と第三の部材１０３との間で押され、図４及び図５に示すように弾性体保持穴１２内を埋めると共にその周囲に広がって、第一の部材１０１、第二の部材１０２及び第三の部材１０３による三面合わせ部によくいきわたるので、第三の部材１０３に対する第一の部材１０１の対向面１０１ａと第二の部材１０２の対向面１０２ａに、両者の加工公差や、熱膨張差、あるいは微小な取付誤差などによる段差があっても、これを埋めることができ、このような状態で加硫硬化したゴム状弾性体２は、第一の部材１０１及び第二の部材１０２と第三の部材１０３に良好に密接することになる。   And the gasket main body 1 which apply | coated the liquid gasket is interposed between the 1st member 101, the 2nd member 102, and the 3rd member 103, and these 1st member 101 and the 2nd member 102 are interposed. In the process of fastening the third member 103, the gasket body 1 is deformed such that the beads 11, 11 are crushed, so that the liquid gasket is in contact with the first member 101 and the second member 102. The first member 101, the second member 102, and the third member are pressed between the first member 103 and the elastic member holding hole 12 as shown in FIGS. 103 is often applied to the three-surface mating portion, so that the opposing surface 101a of the first member 101 and the opposing surface 102a of the second member 102 with respect to the third member 103 have processing tolerances, thermal expansion differences, Even if there is a step due to a minute mounting error, it can be filled, and the rubber-like elastic body 2 vulcanized and cured in such a state is combined with the first member 101 and the second member 102. Good contact with the third member 103 is obtained.

しかも、ゴム状弾性体２は弾性体保持穴１２内を埋めると共に、ビード１１，１１の間隔が広がっている部分に保持されているので、その保持量が十分に多く、このため、優れたシール性を奏することができる。   In addition, since the rubber-like elastic body 2 fills the elastic body holding hole 12 and is held in a portion where the distance between the beads 11 and 11 is widened, the holding amount is sufficiently large, and thus an excellent seal is achieved. Can play sex.

上述した第一の実施の形態は、ビード１１，１１がフルビードからなるものであるが、図６及び図７に示す第二の実施の形態は、ビード１１，１１がハーフビードからなるものである。   In the first embodiment described above, the beads 11 and 11 are made of full beads. In the second embodiment shown in FIGS. 6 and 7, the beads 11 and 11 are made of half beads.

すなわちガスケット本体１には、内周側及び外周側のハーフビードからなる二条のビード１１，１１が周設されている。すなわちガスケット本体１のビード１１，１１は、なだらかな段差状に打ち出し形成されたハーフビードからなるものであって、長孔状の弾性体保持穴１２や、ボルト挿通穴などの複数の円形穴１３（図１参照）は、このビード１１，１１の間の平坦な***部１４ａに開設されている。   That is, the gasket body 1 is provided with two beads 11, 11 formed of inner and outer half beads. That is, the beads 11 and 11 of the gasket body 1 are made of half beads that are formed in a gentle step shape, and are formed of a plurality of circular holes 13 (e.g., long hole-like elastic body holding holes 12 and bolt insertion holes). 1) is provided in a flat raised portion 14a between the beads 11, 11.

ＦＩＰＧ（Formed-in-Place Gasket)などの液状ガスケットの硬化物からなるゴム状弾性体２は、高粘度の液状すなわち未加硫状態でガスケット本体１の弾性体保持穴１２及びその周囲に塗布され、加硫硬化することによって前記弾性体保持穴１２保持されており、第一の部材１０１、第二の部材１０２及び第三の部材１０３に密接されるものである。   A rubber-like elastic body 2 made of a cured product of a liquid gasket such as FIPG (Formed-in-Place Gasket) is applied to the elastic body holding hole 12 of the gasket body 1 and its surroundings in a highly viscous liquid state, that is, in an unvulcanized state. The elastic body holding hole 12 is held by vulcanization and curing, and is in close contact with the first member 101, the second member 102, and the third member 103.

したがって、この実施の形態による三面合わせ部用ガスケットも、先に説明した第一の実施の形態と同様の効果を実現することができる。   Therefore, the gasket for the three-surface mating portion according to this embodiment can also achieve the same effects as those of the first embodiment described above.

なお、ビード１１としては、図示の例のようなフルビードやハーフビードのほかにも、台形状に屈曲形成したビードなど、種々のビードが適用可能である。   As the bead 11, various beads such as a bead bent in a trapezoidal shape can be applied in addition to the full bead and the half bead as shown in the illustrated example.

本発明に係る三面合わせ部用ガスケットは、自動車の内燃機関におけるシリンダブロック及びチェーンケースとシリンダヘッドなどのような、三つの部材の組み合わせにより形成される三面合わせ部のシール手段として利用することができる。   The gasket for a three-surface mating portion according to the present invention can be used as a sealing means for a three-surface mating portion formed by a combination of three members such as a cylinder block and a chain case and a cylinder head in an internal combustion engine of an automobile. .
