本考案は、金属積層形シリンダヘッドガスケットに関し、更に詳細には、シリ ンダ穴のシール部の構造に特徴のある金属積層形シリンダヘッドガスケットに関 するものである。 The present invention relates to a metal laminated cylinder head gasket, and more specifically, to a cylinder head gasket. Regarding the metal laminated cylinder head gasket, which has a unique structure of the seal part of the cylinder hole. It is something to do.
【０００２】0002
内燃機関の金属積層形シリンダヘッドガスケットのシリンダ穴には、例えば、 ドイツ特許公開第DE 3245383 A1 号公報に記載されているように、該シリンダ穴 の周囲を囲むビードと、該ビードを覆う金属板から成るグロメットとを設け、積 層板間に燃焼ガスが進入しないようにしたものがある。更に、別の金属積層形シ リンダヘッドガスケットとしては、高温高圧ガスをシールするために、シール部 を２重に設けたものが使用されていることは周知である。そして、前記２重シー ル部の構造としては、内燃機関のシリンダボアの構造に合わせて種々のものがあ る。 For example, in the cylinder hole of the metal laminated cylinder head gasket of an internal combustion engine, As described in German Patent Publication No. DE 3245383 A1, the cylinder bore A bead that surrounds the periphery and a grommet made of a metal plate that covers the bead are provided. Some are designed to prevent combustion gas from entering between the laminar plates. Furthermore, another metal laminated system As a cylinder head gasket, the seal part is used to seal high temperature and high pressure gas. It is well known that a double-layer structure is used. And the double sea There are various structures of the cylinder bore depending on the structure of the cylinder bore of the internal combustion engine. Ru.
【０００３】 即ち、前記２重シール部の特徴として、例えば、シリンダ穴に対し中側のシー ル部剛性を外側のシール部剛性より低くし、シリンダライナーの鍔部付け根部や 、シリンダボディの前記鍔の支持部の付け根に、集中応力が発生しないようにし たもの、かかる応力の発生が問題とならない場合には、前記と逆に、中側のシー ル部剛性を外側シール部剛性より高くし、シリンダ穴から接合面に燃焼ガスが侵 入することの防止を主体とし、外側シール部を補助的に考えるようにしたもの、 などがある。そして、高い剛性のシール部を得る手段として、ワイヤーリングと したものがある。また、ビードの弾性の調節は、ビードの幅や高さ、板厚、材質 の硬度などを変化させて行うことができる。0003 That is, as a feature of the double seal part, for example, the inner seal with respect to the cylinder hole The rigidity of the seal part is lower than that of the outer seal part, and the , to prevent concentrated stress from occurring at the base of the support part of the flange of the cylinder body. However, if the generation of such stress is not a problem, reverse the above, and The rigidity of the seal part is made higher than the rigidity of the outer seal part, and combustion gas invades the joint surface from the cylinder hole. The main purpose is to prevent water from entering, and the outer seal part is considered as an auxiliary part. and so on. Then, as a means to obtain a highly rigid seal, we used a wire ring. There is something I did. In addition, the elasticity of the bead can be adjusted by adjusting the bead width, height, plate thickness, and material. This can be done by changing the hardness etc.

以上の目的を達成するための本考案の金属積層形シリンダヘッドガスケットの 構成は、シリンダ穴の周囲に、中側にワイヤーリングから成る主シール部と外側 にビードから成る副シール部とから成る２重のシール部を形成し、シリンダ穴の 周囲を囲む金属薄板から成るグロメットを、該グロメットの一方の鍔部は主シー ル部のみ覆い、他方の鍔部は副シール部まで覆うように形成し、主シール部の圧 縮時厚みより、副シール部の合計板厚を薄くし、次いで、平坦部の合計板厚を薄 くしたものである。 The metal laminated cylinder head gasket of this invention was developed to achieve the above objectives. The structure consists of a main seal consisting of a wire ring around the cylinder hole, and a wire ring on the outside. A double seal part consisting of a sub-seal part consisting of a bead is formed at the bottom of the cylinder hole. A grommet made of a thin metal plate surrounding the periphery, one flange of the grommet is attached to the main seam. The other flange is formed to cover only the sub-seal part, and the pressure of the main seal part is The total plate thickness of the sub-seal part is made thinner than the reduced thickness, and then the total plate thickness of the flat part is made thinner. It's a good thing.
【０００６】 本考案は、前記のとおり、主シール部の圧縮時厚みより、副シール部の合計板 厚を薄くし、次いで、平坦部の合計板厚を薄くすることによって、シリンダ穴の 周縁で燃焼ガスの侵入を防止し、ヘッドボルトによる締め付けでシリンダヘッド が反り、接合面の間隙が変化した場合でも、この変化を補償し、主・副シール部 のそれぞれに所定のシール性能を発生させる作用がある。[0006] As mentioned above, in this invention, the total thickness of the sub-seal part is calculated based on the compressed thickness of the main seal part. of the cylinder hole by reducing the thickness and then reducing the total plate thickness of the flat section. The peripheral edge prevents combustion gas from entering, and the cylinder head can be tightened with head bolts. Even if the seal is warped and the gap between the joint surfaces changes, this change is compensated for and the main and sub seal parts are Each of them has the effect of generating a predetermined sealing performance.

以下添付の図を対照して、一実施例により本考案を具体的に説明する。 図１に示す実施例の金属積層形シリンダヘッドガスケット（以下単にガスケッ トという）１は、シリンダ穴２の周囲に取り付けたグロメット４、該グロメット ４の断面Ｕ状に折り返した部分に配置されたワイヤーリング５、一方の表面板を 兼ねるビード板６、中板８，10、及び、他方の表面板12から成るものであり、ビ ード板６には、ビード14を設けている。そして、シリンダ穴２を囲み、ワイヤー リング５による主シール部16と、ビード14による副シール部18とを形成し、前記 グロメット４の一方の鍔20は主シール部16のみ覆う幅に形成し、他方の鍔22は副 シール部18まで覆う幅に形成した。 Hereinafter, the present invention will be described in detail with reference to an embodiment with reference to the accompanying drawings. The metal laminated cylinder head gasket (hereinafter simply referred to as gasket) of the embodiment shown in Fig. 1 is a grommet 4 attached around the cylinder hole 2; Wire ring 5 placed on the folded part of 4 with a U-shaped cross section, one surface plate It consists of a bead plate 6, which also serves as a bead plate, middle plates 8 and 10, and the other surface plate 12. A bead 14 is provided on the board plate 6. Then, surround cylinder hole 2 and wire A main seal part 16 by the ring 5 and a sub-seal part 18 by the bead 14 are formed, and the above-mentioned One collar 20 of the grommet 4 is formed to a width that covers only the main seal portion 16, and the other collar 22 is formed to have a width that covers only the main seal portion 16. It is formed to have a width that covers up to the seal portion 18.
【０００８】 即ち、主シール部16は、ワイヤーリング５、グロメット４の鍔20,22 、ビード 板６、及び、表面板12によって形成し、ガスケット１をシリンダヘッド（図示せ ず）とシリンダボディ（同様に図示せず）で圧縮した際に、ワイヤーリング５の 弾性により高いシール面圧を発生させるようにした。 次に、副シール部18は、グロメット４の一方の鍔22、ビード板６のビード14を 設けた部分、中板10、及び表面板12によって形成し、積層した板6,10,12 及び22 の合計板厚を、主シール部16の圧縮時の厚みより薄く形成し、ガスケット１を圧 縮した際に、ビード14の弾性によって、シール面圧を発生させるようにした。し たがって、該副シール部18のシール面圧は、主シール部16のシール面圧より低い 値となる。[0008] That is, the main seal part 16 is formed by the wire ring 5, the collars 20 and 22 of the grommet 4, and the bead. The gasket 1 is formed by the plate 6 and the surface plate 12, and the gasket 1 is attached to the cylinder head (not shown). When compressed by the cylinder body (also not shown), the wire ring 5 The elasticity generates high seal surface pressure. Next, the sub seal portion 18 seals one collar 22 of the grommet 4 and the bead 14 of the bead plate 6. Laminated plates 6, 10, 12 and 22 formed by the provided portion, the middle plate 10, and the top plate 12 The total plate thickness of the main seal part 16 is formed to be thinner than the compressed thickness of the main seal part 16, and the gasket 1 is compressed. When contracted, the elasticity of the bead 14 generates sealing surface pressure. death Therefore, the seal surface pressure of the sub-seal section 18 is lower than the seal surface pressure of the main seal section 16. value.
【０００９】 更に、鍔22の外側の平坦部24は、ビード板６、中板８，10、及び表面板12によ って形成し、該平坦部24は、図示しないシリンダヘッドなどの接合面が、ヘッド ボルト（図示せず）の締め付け力により変形するなど、平坦性が失われた場合以 外、接合面に接触しないようにした。 即ち、主シール部16を圧縮した際の厚みをｔB で表し、副シール部18の合計板 厚をｔS で表し、平坦部24合計板厚をｔF で表すと、ｔB＞ｔS＞ｔF で表すこと ができる。以上説明した実施例のガスケット１を、図示しないシリンダヘッドと シリンダボディとの間に介装し、ヘッドボルトで締め付けると、主シール部16に 高いシール面圧が発生して燃焼ガスの侵入を防ぐと共に、副シール部18を高い圧 縮力と高温の燃焼ガスから保護する。したがって、なんらかの理由で主シール部 から燃焼ガスが洩れることがあっても、副シール部で確実に洩れを防止すること ができる。Furthermore, the flat part 24 on the outside of the flange 22 is formed by the bead plate 6, the middle plates 8, 10, and the surface plate 12, and the flat part 24 is such that the joint surface of a cylinder head (not shown) or the like is connected to the head. It was made so that it did not come into contact with the joint surface unless the flatness was lost, such as when it was deformed by the tightening force of a bolt (not shown). That is, if the thickness of the main seal part 16 when compressed is represented by t B , the total thickness of the sub-seal part 18 is represented by t S , and the total thickness of the flat part 24 is represented by t F , then t B > t S > tF . When the gasket 1 of the embodiment described above is interposed between a cylinder head and a cylinder body (not shown) and tightened with a head bolt, high seal surface pressure is generated in the main seal portion 16 to prevent combustion gas from entering. At the same time, the sub-seal portion 18 is protected from high compression force and high temperature combustion gas. Therefore, even if combustion gas leaks from the main seal part for some reason, the leakage can be reliably prevented by the sub seal part.

以上説明したように本考案の金属積層形シリンダヘッドガスケットを構成した ので、シリンダヘッドがヘッドボルトの締め付けにより変形し、シリンダ穴の周 囲で、接合面の間隙が開くなどのことがあっても、比較的簡単な構造で、ワイヤ ーリングによる中側の主シール部に最も高いシール面圧を発生させると共に、副 シール部を保護することができ、接合面とガスケットとの間に燃焼ガスが洩れる ことがなく、また、主シール部から、僅かに燃焼ガスが洩れても、副シール部で 確実に洩れをくい止めることができる。 As explained above, the metal laminated cylinder head gasket of the present invention was constructed. Therefore, the cylinder head may be deformed due to the tightening of the head bolts, causing damage to the circumference of the cylinder hole. Even if there is a gap between the joint surfaces, the wire can be The highest seal surface pressure is generated at the main seal part on the inside by the ring, and the secondary It can protect the seal part and prevent combustion gas from leaking between the joint surface and the gasket. In addition, even if a small amount of combustion gas leaks from the main seal, the sub-seal will not leak. You can definitely stop leaks.
