Description
본 발명에 따른 자동차용 누유 방지용 헤드커버 가스켓 구조에 관한 것으로서, 더욱 상세하게는 실린더 헤드와 헤드 커버의 접합면 사이에 설치되는 헤드커버 가스켓의 접촉 리브의 형상을 변경하여 오일이 외부로 누출되는 것을 방지할 수 있는 자동차용 누유 방지용 헤드커버 가스켓 구조에 관한 것이다.The present invention relates to a leakproof head cover gasket structure for an automobile according to the present invention. More particularly, the oil leaks to the outside by changing the shape of the contact ribs of the head cover gasket installed between the joining surface of the cylinder head and the head cover. The present invention relates to a structure for preventing leakage of a car head that can be prevented.
일반적으로 자동차용 헤드 커버 가스켓은 가솔린과 공기를 혼합한 혼합기를 실린더 내부에 흡입 후 피스톤으로 압축하여 이것에 스파크 플러그에 의해 전기 불꽃으로 점화 연소시켜서 이때 발생하는 압력을 피스톤으로 받아 동력을 발생시키는 엔진 본체에 형성한 실린더 헤드와 헤드 커버 사이의 접합면에 끼워져 엔진 오일이나 연소 가스가 누출되는 것을 방지하는 작용을 한다.In general, the head cover gasket for an automobile is an engine that generates gas by injecting a mixture of gasoline and air into a cylinder, compresses it with a piston, and then ignites and burns it with an electric spark by a spark plug. It is fitted to the joint surface between the cylinder head and the head cover formed in the main body to prevent leakage of engine oil or combustion gas.
상기 헤드 커버 가스켓은 온도 변화에 신축성있게 대응하고 고온에 견디는 불소계 성질이 강한 것을 써야 하며 또한 오일에 잠겨있기 때문에 내유성이 있는 재질을 사용해야 한다.The head cover gasket should be made of a material that is flexible to cope with temperature changes and has a strong fluorine-based property to withstand high temperatures, and is also resistant to oil, and thus should be oil-resistant.
도 3와 도 4에 도시된 바와 같이, 상기 헤드 커버 가스켓(100)은 실린더 헤드(200)와 헤드커버(300)의 접합면 형상과 동일한 형상으로 이루어져 있으며, 특히 스파크 플러그 홀(미도시)에도 헤드커버 가스켓(110)이 설치되어 있다.As shown in FIGS. 3 and 4, the head cover gasket 100 is formed in the same shape as the joining surface shape of the cylinder head 200 and the head cover 300, and particularly in the spark plug hole (not shown). The head cover gasket 110 is installed.
또한, 상기 헤드커버 가스켓(100)의 단면 형상은 도 5에 도시된 바와 같이, 상기 실린더 헤드(200)에 헤드커버 가스켓(100)의 접촉 리브(110)가 2열로 배열되어 접촉 리브(110)와 동일한 형상의 삽입홈(210)에 삽입되어 있고, 헤드커버(300)의 가스켓 수용홈(310)에는 독립열의 접촉 리브(110)가 수용되어 있으며, 이 가스켓 수용홈(310)에는 압착된 피프(pip)(120)가 장착되어 있는바, 상기 피프(120)는 헤드커버 가스켓(100)이 이탈되지 않도록 하는 역할을 한다.In addition, the cross-sectional shape of the head cover gasket 100 is as shown in FIG. 5, the contact ribs 110 of the head cover gasket 100 are arranged in two rows on the cylinder head 200 so that the contact ribs 110 are formed. It is inserted into the insertion groove 210 of the same shape as, and the gasket receiving groove 310 of the head cover 300 is housed in a separate row of contact ribs 110, the gasket receiving groove 310 is compressed (pip) 120 is mounted, the pipe 120 serves to prevent the head cover gasket 100 from being separated.
그런데, 종래의 헤드커버 가스켓(100)은 상기 접촉 돌기(110)의 접촉 상태가 나쁠 경우, 뒤틀리게 되고, 그로인해 상기 헤드커버 가스켓(100)의 밀폐 불량이 발생되어 실린더 헤드(200) 안의 오일이 누출되는 경우가 자주 발생하게 되는 문제점이 있다.However, the conventional head cover gasket 100 is distorted when the contact state of the contact protrusion 110 is bad, thereby causing a poor sealing of the head cover gasket 100, so that oil in the cylinder head 200 may be leaked. There is a problem that frequently occurs leaks.
따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 안출한 것으로서, 2열로 배열된 접촉 리브에 일정간격을 두고 수직으로 배치된 지지부를 일체 형성하여 상기 접촉 리브가 서로 지지될 수 있도록 함으로써, 헤드커버 가스켓의 오일 밀폐 효율을 크게 향상시킬 수 있는 자동차용 누유 방지용 헤드커버 가스켓 구조를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, by integrally forming a support portion arranged vertically at regular intervals on the contact ribs arranged in two rows so that the contact ribs can be supported with each other, the head cover gasket It is an object of the present invention to provide a leak-proof head cover gasket structure for automobiles that can greatly improve the oil sealing efficiency of the vehicle.

이하, 상기와 같은 목적을 달성하기 위한 본 발명의 특징에 대해 설명하면 다음과 같다.Hereinafter, the features of the present invention for achieving the above object are as follows.
본 발명은 실린더 헤드(200)와 헤드커버(300)의 실링성을 위해 장착되며, 2열로 배열된 접촉 리브(110)가 구비된 헤드커버 가스켓(100)에 있어서,In the present invention, the head cover gasket 100 is mounted for sealing of the cylinder head 200 and the head cover 300, and is provided with contact ribs 110 arranged in two rows.
상기 접촉 리브(11)의 뒤틀림을 방지할 수 있도록 2열의 접촉 리브(11)에는일정간격마다 각 열 사이를 가로지르는 지지부(11a)가 일체 형성된 것을 특징으로 한다.In order to prevent the contact ribs 11 from being warped, two rows of contact ribs 11 may be integrally formed with support portions 11a crossing each row at regular intervals.
이하, 첨부도면을 참조하여 본 발명의 구성에 대해 상세하게 설명하면 다음과 같다.Hereinafter, the configuration of the present invention with reference to the accompanying drawings in detail.
도 1은 본 발명에 따른 자동차용 누유 방지용 헤드커버 가스켓 구조를 나타내는 사시도이고, 도 2는 도 1의 'A-A'선 단면도를 나타낸다.1 is a perspective view showing the structure of the vehicle leakage preventing head cover gasket according to the present invention, Figure 2 is a cross-sectional view taken along the line 'A-A' of FIG.
도 1에 도시된 바와 같이, 실린더 헤드(200)와 헤드커버(300) 사이의 접합면에 밀착되는 접촉 리브(310)가 형성된 헤드커버 가스켓(100)에 있어서, 상기 헤드커버 가스켓(10)은 헤드커버(300)의 가스켓 수용홈(310)에 수용되어 압착되는 피프(pip)(12)가 일체 형성되어 있는바, 상기 피프(12)는 가스켓 하우징의 좌우 측면에 각각 반원통 형상으로 형성되어 있다.As shown in FIG. 1, in the head cover gasket 100 having contact ribs 310 formed in close contact with the bonding surface between the cylinder head 200 and the head cover 300, the head cover gasket 10 is formed. A pipe 12 that is received and compressed in the gasket receiving groove 310 of the head cover 300 is integrally formed. The pipes 12 are formed in semi-cylindrical shapes on the left and right sides of the gasket housing, respectively. have.
한편, 상기 헤드커버 가스켓(10)의 상단면과 하단면에는 가스켓의 실링(sealing)성을 향상하기 위한 접촉 리브(11)가 형성되어 있는바, 상기 헤드커버(300)의 가스켓 수용홈(310)에는 독립열로 배열된 접촉 리브(11)가 피프(12)와 더불어 압착되어 있으며, 하단에는 헤드커버 가스켓(10)의 접촉 리브(11)가 2열로 배열되어 접촉 리브(11)와 동일한 형상의 실린더 헤드(200)의 삽입홈(210)에 삽입되어 있다.On the other hand, the upper and lower surfaces of the head cover gasket 10 is formed with contact ribs 11 for improving the sealing (sealing) of the gasket bar gasket receiving groove 310 of the head cover 300 The contact ribs 11 arranged in an independent row are pressed together with the pipes 12, and the contact ribs 11 of the head cover gasket 10 are arranged in two rows at the bottom thereof to have the same shape as the contact ribs 11. It is inserted into the insertion groove 210 of the cylinder head 200.
상기와 같은 구성으로 이루어진 헤드커버 가스켓(10)의 오일 밀폐 효율을 더욱 향상하기 위해 본 발명은 실린더 헤드(200)의 삽입홈(210)에 삽입되는 2열로 배열된 접촉 리브(11)에 일정간격을 두고 수직으로 배치된 지지부(11a)가 일체 형성되어 있는바, 상기 지지부(11a)는 2열로 배열된 접촉 리브(11)를 서로 지지하기 때문에 상기 접촉 리브(11)의 뒤틀림에 의한 헤드커버 가스켓(10)의 밀폐 불량을 방지할 수 있다.In order to further improve the oil sealing efficiency of the head cover gasket 10 having the configuration described above, the present invention provides a predetermined interval between the contact ribs 11 arranged in two rows inserted into the insertion groove 210 of the cylinder head 200. Since the support portions 11a vertically arranged with respect to each other are integrally formed, the support portions 11a support the contact ribs 11 arranged in two rows, so that the head cover gasket due to the twisting of the contact ribs 11 is provided. Poor sealing of (10) can be prevented.
이상에서 상술한 바와 같이, 본 발명에 따른 자동차용 누유 방지용 헤드커버 가스켓 구조는 2열로 배열된 접촉 리브에 일정간격을 두고 수직으로 배치된 지지부를 일체 형성함으로써, 실린더 헤드와 헤드커버의 접합면 사이에 설치되는 헤드커버 가스켓의 접촉 돌기의 접촉 상태가 나쁠 경우, 뒤틀리게 되고, 그로인해 밀폐 불량이 발생된 기존의 헤드커버 가스켓 대비, 오일 밀폐 효율을 크게 향상시킬 수 있는 효과가 있다.As described above, the vehicle leakage preventing head cover gasket structure according to the present invention is integrally formed between the contact surfaces of the cylinder head and the head cover by integrally forming a support part vertically disposed at regular intervals in contact ribs arranged in two rows. If the contact state of the contact projection of the head cover gasket to be installed in the bad, it is distorted, thereby resulting in an effect that can significantly improve the oil sealing efficiency, compared to the existing head cover gasket where the sealing failure occurs.
