본 발명은 내연기관의 가스켓에 관한 것으로서, 보다 상세하게는 가스켓의 시일판(seal plate)을 개선하여 국부적인 열변형에 의해서도 시일성을 유지할 수 있게 한 내연기관의 가스켓에 관한 것이다.The present invention relates to a gasket of an internal combustion engine, and more particularly, to a gasket of an internal combustion engine that can improve the seal plate of the gasket to maintain sealing even by local thermal deformation.
일반적으로 실린더 헤드 가스켓이란 실린더 블록과 실린더 헤드 사이에 장착되어 실린더 헤드 볼트의 적정 출력에 의해 체결되어 엔진 작동시 폭발에 의한 최대 압력 증대시 가스의 노출을 방지하고 각 워터자켓과 오일홀들 사이의 누유를 방지하게 하는 부품이다.In general, the cylinder head gasket is mounted between the cylinder block and the cylinder head and is fastened by the proper output of the cylinder head bolt to prevent gas exposure when the maximum pressure caused by the explosion during engine operation increases, and between the water jacket and the oil holes This part prevents leakage.
실린더 헤드 가스켓은 석면계(ASBESTOS)에서 비석면계(ARAMIDE, GRAPHITE)로비석면계에서 스틸 박판(STEEL LAMINATE)계로 발전하였으며, 현재는 주류가 스틸 박판 타입이 대부분이다.The cylinder head gasket has developed from ASBESTOS to ARAMIDE, GRAPHITE and from asbestos to STEEL LAMINATE.
도3은 종래기술인 가스켓을 도시한 도면으로, 가스켓(2)은 상층부에 위치하고, 가장자리에 라운드형으로 절곡시킨 그로멧트(4)를 형성하고 있으며, 구멍(6)과 그로멧트(4)사이에 제1오목라인홈(8)을 형성한 제1시일판(10)을 두고 있다.Fig. 3 shows a gasket of the prior art, wherein the gasket 2 is located in the upper layer and forms a grommet 4 bent in a round shape at the edge, between the hole 6 and the grommet 4; A first seal plate 10 having a first concave line groove 8 is provided.
상기한 제1시일판(10)의 저면에는 구멍(6)에서 제1오목라인홈(8)전까지 개재된 제2오목라인홈(12)을 형성한 제2시일판(14)을 개재하고 있다.The bottom surface of the first seal plate 10 is interposed with a second seal plate 14 having a second concave line groove 12 interposed from the hole 6 to the first concave line groove 8. .
상기한 제2시일판(14)의 저면으로부터 제1시일판(10)의 그로멧트(4)에 개재되어 돌출 형성된 볼록라인홈(16)을 형성한 제3시일판(18)을 개재하여 이루어지고 있다.It is made through the third seal plate 18 formed with the convex line groove 16 protruding from the bottom of the second seal plate 14 to the grommet 4 of the first seal plate 10. ought.
상기한 가스켓(2)은 소형 고출력 대응을 위한 3-레이어 타입이다.The gasket 2 is a three-layer type for a small high power counterpart.
상기한 가스켓(2)은 실린더 헤드 볼트 체결시 제3시일판(18)의 볼록라인홈(16)에 최대 압력이 발생하고 제1오목라인홈(8)과 제2오목라인홈(12)을 형성하므로서 2차 3차까지 시일성을 보정하게 된다.When the gasket 2 is fastened to the cylinder head bolt, the maximum pressure is generated in the convex line groove 16 of the third seal plate 18 and the first concave line groove 8 and the second concave line groove 12 are formed. By forming, the sealing property is corrected up to the second to third order.
이러한 종래기술은 제3시일판을 제조하는 프레스 공정에서 금형에 의해 볼록라인홈을 성형하여 만드는 단순구조로 실린더 헤드의 열변형, 실린더 블록(B)의 열변형에 의한 전체적이거나 부분적인 평면도 공차범위를 상실했을 때는 시일성을 확신할 수 없는 문제점이 있다.This prior art is a simple structure made by forming a convex line groove by a mold in the press process for manufacturing the third seal plate, the overall or partial plan view tolerance range due to the heat deformation of the cylinder head, the heat deformation of the cylinder block (B). There is a problem when you can not be sure when the seal.
제3시일판의 볼록라인홈(16)에 P¹~P⁴걸쳐서 압력을 받으면 실린더 보어주변의 실린더 헤드나 실린더 블록(B)의 변형(국부적인 기계적 변형, 열변형)시는 변형된 공간까지 압력이 전달되지 않아 누유가 발생하는 문제점이 있다.When pressure is applied across the convex line groove 16 of the third seal plate, the pressure is applied to the deformed space during deformation (local mechanical deformation, thermal deformation) of the cylinder head or cylinder block B around the cylinder bore. There is a problem that the leakage does not occur.
상기한 바와 같은 종래기술의 문제점을 해소하기 위하여 발명된 것으로서, 본 발명의 목적은 가스켓의 시일판중 하나를 개선하여 국부적인 열변형에 의해서도 시일성을 유지할 수 있게 한 내연기관의 가스켓 구조를 제공하는데 있다.In order to solve the problems of the prior art as described above, an object of the present invention is to provide a gasket structure of the internal combustion engine to improve one of the seal plate of the gasket to maintain the sealability even by local thermal deformation. It is.

26:제3시일판 28:볼록라인홈 (a)(b)(c)(…):조각 플레이트26: Third seal 28: Convex line groove (a) (b) (c) (…): engraving plate
이를 실현하기 위하여 본 발명은 가스켓이 제1,2,3시일판으로 구성되어 이루어지는 내연기관의 가스켓에 있어서,In order to realize this, the present invention provides a gasket of an internal combustion engine comprising a gasket comprising first, second, and third seal plates,
제3시일판의 볼록라인홈을 형성한 부분이 원주 전둘레에 걸쳐 일정 크기의 조각 플레이트로 분할한 후 높낮이를 교대로 달리하여 형성함을 특징으로 하는 내연기관의 가스켓을 제공하는데 있다.It is to provide a gasket of the internal combustion engine, characterized in that the portion forming the convex line groove of the third seal plate is divided into pieces of a predetermined size over the entire circumference of the circumference and formed by alternating heights.
본 발명은 제3시일판의 볼록라인홈을 형성한 원주 전둘레에 걸쳐 일정 크기로 분할 절단하여 실린더 블록이나 실린더 헤드의 국부적인 변형 부위에서 각각의 조각 플레이트들이 각 실린더블럭이나 실린더 헤드부위에서 변형된 형태만큼 변형을 용이하게 일으킴에 따라 능동적으로 완벽한 시일성을 도모하게 된다.The present invention divides and cuts each piece plate at each cylinder block or cylinder head at a local deformation area of the cylinder block or cylinder head by dividing and cutting a predetermined size over the entire circumference of the circumference forming the convex line groove of the third seal plate. As the deformation is as easy as it is, the active seal can be perfectly sealed.
이하, 본 발명의 바람직한 일 실시예를 첨부한 도면에 의거하여 보다 상세히 설명한다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도1은 본 발명에 따른 가스켓을 도시한 사시도이고, 도2는 도1의 A부를 확대한 도면이다.1 is a perspective view showing a gasket according to the present invention, Figure 2 is an enlarged view of a portion A of FIG.
가스켓(20)이 제1,2,3시일판(22)(24)(26)으로 구성되어 이루어지는데, 여기에서 제3시일판(26)의 볼록라인홈(28)을 형성한 부분의 원주 전둘레에 걸쳐 일정 크기의 조각 플레이트(a)(b)(c)(…)로 분할한 후 높낮이를 교대로 달리하여 형성하고 있다.The gasket 20 is composed of first, second and third seal plates 22, 24 and 26, wherein the circumference of the portion where the convex line groove 28 of the third seal plate 26 is formed. After dividing into pieces (a) (b) (c) (...) of a certain size over the entire circumference, the height is alternately formed.
상기한 조작플레이트(a)(b)(c)등의 절개정도는 볼록라인홈(28)의 양측으로 연장된 제3시일판(26)과 동일 비율로 한다.The cutting degree of the operation plates (a), (b) and (c) described above is the same ratio as that of the third seal plate 26 extending to both sides of the convex line groove 28.
상기한 바와 같이 이루어지는 본 발명의 작용은 가스켓(20)의 제3시일판(26)에 형성한 볼록라인홈(28)을 따라 원주 전둘레에 걸쳐 일정 크기로 분할 절단하여 조작플레이트(a)(b)(c)(…)를 형성한다.The operation of the present invention made as described above is divided into a predetermined size over the entire circumference along the convex line groove 28 formed in the third seal plate 26 of the gasket 20 to operate the plate (a) ( b) (c) (...) is formed.
그리고 상기한 조각 플레이트(a)(b)(c)들은 상호 교대로 높낮이를 달리하여 형성하고 있음에 따라 탄성력을 보강하게 된다.And the piece plates (a) (b) (c) are to reinforce the elastic force as they are formed by alternating heights alternately.
이로서 실린더보어(30)실린더 블록이나 실린더 헤드의 국부적인 변형 부위에서 각각의 제3시일판(26)의 조각 플레이트(a)(b)(c)들이 각 실린더블럭이나 실린더 헤드부위에서 변형된 형태만큼 변형을 용이하게 일으키게 된다.As a result, the fragment plates (a) (b) (c) of each of the third seal plates 26 are deformed at each cylinder block or cylinder head at the local deformation of the cylinder bore 30 or the cylinder block 30. As much as deformation occurs.
이러한 제3시일판(26)에 조작플레이트(a)(b)(c)를 형성함에 따라 볼록라인홈(28)에 압력이 가해질 때 능동적으로 완벽한 시일성을 도모하게 된다.By forming the operation plates (a) (b) (c) in the third seal plate 26, active pressure is achieved perfectly when the pressure is applied to the convex line groove (28).
이러한 실린더 보어 주변의 블록이나 실린더 헤드의 국부적인 기계적, 열적 변형에서도 완벽한 시일성을 확보하게 된다.This ensures perfect sealing even in local mechanical and thermal deformation of blocks around the cylinder bore or cylinder head.
