Description
본 고안은 배기매니폴드의 시일성 향상을 위한 접속 구조 개선에 관한 것이다.The present invention is directed to improving the connection structure for improving the sealability of the exhaust manifold.
종래 배기매니폴드(10)와 배기매니폴드(11)의 접속부는 도 2 내지 도 4에서와 같이 시일을 위해 익스펜숀링(12)과 시일링(13)을 사용하여 접속부위를 통한 가스의 누설을 방지하고 있다.The connection portion of the conventional exhaust manifold 10 and the exhaust manifold 11 uses an expansion ring 12 and a seal ring 13 for sealing as shown in FIGS. 2 to 4, and leakage of gas through the connection portion. Is preventing.
그러나 상기한 구조는 도시된 것과 같이 익스펜숀링(12)과 시일링(13)의 단면 형상이 각기 4각으로 되어 있어 탄성력이 축과 직각방향으로만 작용하므로 양측부재의 경계부위인 모서리부에의 밀착성 감소로 인해 각 부재들의 접촉 틈새를 통해 가스가 외부로 누설되는 문제점이 있다.However, the structure described above has four cross-sectional shapes of the expansion ring 12 and the seal ring 13, respectively, so that the elastic force acts only in the direction perpendicular to the axis. Due to the reduced adhesion of the gas through the contact gap of each member there is a problem that the gas leaks to the outside.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 바는 배기매니폴드의 접속부위의 시일성을 향상하여 배기가스의 누설을 차단하는 접속 구조를 제공하는 데 있다.The present invention has been proposed in view of the above problems, and an object thereof is to provide a connection structure for preventing leakage of exhaust gas by improving the sealability of the connection portion of the exhaust manifold.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
도 1은 본 고안에 의한 배기매니폴드의 시일 접속구조를 나타내는 도면으로 도면에 있어서, 부호 1과 2는 각각 상호 접속되는 배기매니폴드이다.BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a view showing a seal connecting structure of an exhaust manifold according to the present invention, wherein reference numerals 1 and 2 denote exhaust manifolds which are connected to each other.
7일측 배기매니폴드(1)는 타측 배기매니폴드(2)의 확관부(3)내로 삽입되고 양측부재 사이에 형성되는 공간부(4)에는 익스펜숀링(5)과 익스펜숀링(5)의 외주에 밀착하는 2개의 시일링(6)(6)이 내장된다.7 The one-side exhaust manifold 1 is inserted into the expansion portion 3 of the other exhaust manifold 2 and has an expansion ring 5 and an expansion ring 5 in the space portion 4 formed between the two members. Two sealing rings (6) (6) in close contact with the outer periphery of the inner part are incorporated.
상기 익스펜숀링(5)은 그의 단면이 반원형으로 형성되며 몸체 일부는 개방되어 있다.The expansion ring 5 has a semicircular cross section and a part of the body is open.
그의 반원형 표면에 밀착하는 상기 시일링(6)(6)의 접촉면(6a)은 반원과 동일한 곡률을 갖는 곡면형상으로 되어 있다. 즉 4각 단면의 한쪽 모서리가 라운딩 형태로 형성되므로써 이에따라 조립시 시일링(6)(6)의 반원형 익스펜숀링(5)의 탄성력에 의해 방사상 방향으로 밀려나면서 공간부(4)의 양측 모서리부에 밀착하게 되어 시일성이 향상된다.The contact surfaces 6a of the seal rings 6 and 6 in close contact with the semicircular surfaces thereof are curved surfaces having the same curvature as the semicircles. That is, since one corner of the quadrilateral cross section is formed in a rounded shape, it is pushed in the radial direction by the elastic force of the semi-circular expansion ring 5 of the seal ring 6 and 6 during assembly. It comes in close contact with and the sealing property improves.
이상과 같은 본 고안에 의한 배기매니폴드의 시일성을 향상하기 위한 접속구조에 의하면 양측 접속 부위의 틈새를 밀봉하기 위하여 사용되는 익스펜숀링이 반원형 단면으로 형성되고 익스펜숀링의 탄성력에 의해 확개되어 밀착하는 시일링은 모서리 일부가 상기 반원의 곡률과 같은 곡면으로 형성되어 곡면 접촉하므로서 익스펜숀링의 탄성력에 의해 시일링이 양측 접속부위의 틈새를 밀봉토록 방사상으로 밀려나 밀착하게 되므로 시일성을 향상하여 배기가스 누출을 방지하게 된다.According to the connection structure for improving the sealability of the exhaust manifold according to the present invention as described above, the expansion ring used to seal the gap between the two connection portions is formed in a semicircular cross section and is expanded by the elastic force of the expansion ring. The sealing ring is in close contact with the curvature of the semi-circle, and the surface of the sealing ring is curved so that the sealing ring is pushed radially to seal the gap between both connecting portions by the elastic force of the expansion ring, thereby improving the sealing property. To prevent the leakage of exhaust gases.
