본 발명은 엔진의 헤드커버에 사용되는 가스켓의 구조에 관한 것으로서, 보다 상세하게는 엔진의 실린더헤드와 헤드커버의 사이에 개재되는 가스켓의 구조에 관한 것이다.The present invention relates to a structure of a gasket used for the head cover of the engine, and more particularly to a structure of a gasket interposed between the cylinder head and the head cover of the engine.

일반적으로 엔진은 공기를 흡입하여 혼합기를 만들고, 이를 연소실에서 연소시킬 때 발생되는 동력을 피스톤과 커넥팅로드 및 크랭크샤프트를 통해 회전력으로 변환시키는 장치이다.In general, the engine is a device that sucks air to make a mixer, and converts the power generated when burning it in the combustion chamber to the rotational force through the piston, connecting rod and the crankshaft.

상기한 바와 같은 엔진은 실린더블록과 실린더헤드가 연소실 및 피스톤의 작동경로를 형성하도록 하여 실질적인 동력을 발생시킬 수 있도록 하고, 상기 실린더헤드측에는 다수의 흡/배기밸브가 설치되어 캠샤프트에 의해 구동되도록 되어 있는 바, 상기 실린더헤드의 상측은 다시 헤드커버로 덮여져 상기 밸브기구들의 작동에 의한 소음이나 밸브기구의 윤활에 사용되는 오일이 외부로 누출되는 것을 방지하도록 하고 있다.The engine as described above allows the cylinder block and the cylinder head to form an operating path of the combustion chamber and the piston to generate substantial power, and a plurality of intake / exhaust valves are installed at the cylinder head side to be driven by the cam shaft. As a result, the upper side of the cylinder head is covered with the head cover again to prevent noise caused by the operation of the valve mechanisms or oil used for lubrication of the valve mechanisms from leaking to the outside.

따라서, 상기 엔진의 실린더헤드와 헤드커버의 결합부위에는 가스켓이 사용되는 바, 종래에 사용되던 가스켓(100)의 형상은 통상 도 1에 도시된 바와 같이 고무재질의 일체형으로 된 것으로서, 그 단면은 도 2에 도시된 바와 같이 종형 또는 단순한 직선형이다.Therefore, a gasket is used at the coupling portion of the cylinder head and the head cover of the engine, and the shape of the gasket 100 used in the related art is generally one-piece of a rubber material as shown in FIG. As shown in FIG. 2, it is vertical or simple straight.

또한, 이러한 가스켓(100)의 설치를 위해 헤드커버(102)에는 도 3에 도시된 것과 같이 그루브(104)를 형성하여 여기에 상기 가스켓(100)이 끼워지도록 하며, 가스켓(100)의 중간중간에는 돌기(미도시)를 형성하여 상기 그루브(104)에 가스켓(100)이 압착되어 빠져나오지 않게 하고 있다.In addition, in order to install the gasket 100, the head cover 102 is formed with a groove 104 as shown in FIG. 3 so that the gasket 100 is fitted therein, and the intermediate middle of the gasket 100. Protrusions (not shown) are formed in the gasket 100 to prevent the gasket 100 from being pressed out.

상기와 같은 가스켓(100)의 설치는 헤드커버(102)에 상기한 바와 같이 가스켓(100)을 끼워 넣은 후 헤드커버(102)를 실린더헤드(106)에 올려놓고 다수의 볼트로 조여서 헤드커버(102)가 실린더헤드(106)에 장착됨과 동시에 가스켓(100)에 의한 밀폐작용이 이루어질 수 있도록 하고 있다.In the installation of the gasket 100 as described above, the gasket 100 is inserted into the head cover 102, and then the head cover 102 is placed on the cylinder head 106 and tightened with a plurality of bolts. 102 is mounted on the cylinder head 106 and at the same time the sealing operation by the gasket 100 can be made.

그런데, 상기와 같이 가스켓(100)을 설치하는 과정 중에는 상기 가스켓(100)을 헤드커버(102)의 그루브(104)에 끼운 상태에서 실린더헤드(106)에 헤드커버(102)를 위치시키기 위해 헤드커버(102)를 뒤집으면 상기 가스켓(100)이 종종 그루브(104)로부터 일부가 이탈되는 현상이 발생하여 작업성이 취약하며, 이를 간과하고 조립작업이 이루어지는 경우에는 기밀이 충분히 유지되지 못하는 문제점이 있다.However, in the process of installing the gasket 100 as described above, the head in order to position the head cover 102 on the cylinder head 106 in the state in which the gasket 100 is inserted into the groove 104 of the head cover 102. When the cover 102 is turned upside down, the gasket 100 is often deviated from the groove 104, so that workability is poor, and when the assembly is performed, the airtightness is not sufficiently maintained. have.

아울러, 종래의 가스켓(100) 단면 형상은 단순한 종형이나 직선형으로 밀폐성능이 충분하지 못하고 소음/진동의 감쇠 능력이 크지 못한 문제점이 있다.In addition, the cross-sectional shape of the conventional gasket 100 has a problem that the sealing performance is not sufficient as a simple vertical or straight shape and the damping ability of the noise / vibration is not large.

이에 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 조립작업시에 가스켓의 이탈 등에 의해 조립 후 기밀유지가 이루어지지 않는 문제를 해결함과 아울러 소음/진동의 감쇠 능력이 크게 향상된 엔진 헤드커버의 가스켓 구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the problems described above, an engine that solves the problem that the airtight is not maintained after assembly due to the separation of the gasket during the assembly operation, and greatly improved the noise / vibration damping ability The purpose is to provide a gasket structure of the head cover.

도 4 내지 도 7은 본 발명 엔진 헤드커버(102)의 가스켓 장착 구조를 도시한 것으로서, 도 4에는 본 발명에 따른 가스켓바아(1)가 도시되어 있고 도 5에는 상기 도 4에 도시된 것과 같은 가스켓바아(1)가 삽입되도록 헤드커버(102)와 실린더헤드(106)에 형성된 가스켓 설치레일(3)의 단면형상을 도시하고 있으며, 도 6에는 상기 가스켓바아(1)가 삽입되는 과정을 도시하고 있고 도 7에는 삽입된 상태의 단면이 도시되어 있다.4 to 7 illustrate a gasket mounting structure of the engine head cover 102 of the present invention, in which a gasket bar 1 according to the present invention is shown in FIG. 4 and FIG. 5 as shown in FIG. The cross-sectional shape of the gasket mounting rail 3 formed on the head cover 102 and the cylinder head 106 is inserted so that the gasket bar 1 is inserted, and FIG. 6 shows a process of inserting the gasket bar 1. 7 shows a cross section in the inserted state.

상기 도 4에 도시된 가스켓바아(1)는 단면형상이 "I"자형으로 형성된 철심(5)의 주위에 고무재질(7)을 둘러싸서 형성된 I자형 단면의 직선형 레일의 구조를 가지도록 만들어졌고, 상기 실린더헤드(106)와 헤드커버(102)에는 상기 가스켓바아(1)의 상측과 하측의 각 단면이 가스켓바아(1)의 길이방향으로 삽입될 수 있도록 가스켓 설치레일(3)이 형성되어 있는데, 이 가스켓 설치레일(3)은 "I"자형 단면의 상측 반은 상기 헤드커버(102)에 하측 반은 상기 실린더헤드(106)에 형성되도록 하여 구성한다.The gasket bar 1 shown in FIG. 4 is made to have a structure of a straight rail having an I-shaped cross section formed by enclosing the rubber material 7 around the iron core 5 having a cross-sectional shape having an “I” shape. In addition, the cylinder head 106 and the head cover 102 are formed with a gasket mounting rail (3) so that each cross section of the upper and lower sides of the gasket bar (1) can be inserted in the longitudinal direction of the gasket bar (1) The gasket mounting rail 3 is configured such that the upper half of the "I" shaped cross section is formed on the head cover 102 and the lower half on the cylinder head 106.

상기한 바와 같이 이루어진 본 발명 엔진 헤드커버의 가스켓 장착 구조는 그 조립과정을 살펴보면, 먼저 실린더헤드(106)의 상측에 헤드커버(102)를 위치시켜 상기 가스켓 설치레일(3)이 온전한 "I'자형을 이룰 수 있도록 한 상태로 가조립한 상태에서, 상기 가스켓바아(1)를 도 6에 도시된 것처럼 엔진의 주위를 둘러싸도록 차례로 다수개 삽입한다.In the gasket mounting structure of the engine head cover of the present invention made as described above, the head cover 102 is first positioned on the upper side of the cylinder head 106 so that the gasket installation rail 3 is intact. In the preassembled state in which it is possible to achieve a shape, a plurality of gasket bars 1 are sequentially inserted to surround the engine as shown in FIG. 6.

다음, 상기와 같은 상태를 지속적으로 유지하면서 볼트를 완전히 조여서 실린더헤드(106)에 헤드커버(102)를 완전히 장착하도록 하면, 상기 가스켓바아(1)는 상기 헤드커버(102)와 실린더헤드(106)에 의해 상하측에 압축력을 부여받아 기밀작용을 시작하게 된다.Next, when the head cover 102 is completely attached to the cylinder head 106 by completely tightening the bolt while maintaining the above state, the gasket bar 1 is connected to the head cover 102 and the cylinder head 106. The compressive force is given to the upper and lower sides by) to start the airtight action.

따라서, 이러한 구조의 헤드커버 가스켓 장착구조에 의하면 조립작업시에 가스켓이 잘못 안착되어 조립 후 원활한 기밀작용을 수행하지 못하는 문제가 근본적으로 해결되며, 상기한 바와 같이 가스켓바아(1)의 단면형상이 "I"자형으로 그 내부에는 "I"자형 철심이 들어 있어서, 소음/진동의 흡수 및 감쇠 특성이 더욱 향상되는 효과를 얻을 수 있다.Therefore, according to the head cover gasket mounting structure of this structure, the problem that the gasket is incorrectly seated at the time of assembling operation and failing to perform a smooth airtight action after assembly is basically solved. As described above, the cross-sectional shape of the gasket bar 1 The "I" shape and the "I" shape iron core are contained therein, so that the effect of further improving the absorption and attenuation characteristics of noise / vibration can be obtained.

이상 설명한 바와 같이 본 발명에 의하면, 가스켓 및 헤드커버의 조립작업시에 가스켓의 이탈 등에 의해 조립 후 기밀유지가 이루어지지 않는 문제를 해결함과 아울러 소음/진동의 감쇠 능력이 크게 향상되도록 한다.As described above, the present invention solves the problem of not maintaining airtightness after assembling due to detachment of the gasket during the assembling operation of the gasket and the head cover, and also greatly improves the noise / vibration damping ability.
