이하 본 고안의 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
도 1은 본 고안에 의한 배기장치를 나타내는 도면으로1 is a view showing an exhaust device according to the present invention
도면중 부호 1은 엔진이며, 엔진의 실린더헤드에는 배기매니폴드(2)가 접속되고, 배기매니폴드(2)에는 촉매변환기(3) 및 배기파이프(4)가 접속된다.In the drawing, reference numeral 1 denotes an engine, and an exhaust manifold 2 is connected to the cylinder head of the engine, and a catalytic converter 3 and an exhaust pipe 4 are connected to the exhaust manifold 2.
상기 배기파이프(4)는 축방향으로 길게 연장되어지고, 무거운 하중체인 배기매니폴드(2)와 촉매변환기(3)를 비롯한 장치 전체를 지지하기 위하여 강체인 지지부재(5)를 통해 엔진에 고정지지되고 있다.The exhaust pipe 4 extends in the axial direction and is fixed to the engine through a rigid support member 5 to support the entire apparatus including the heavy load body exhaust manifold 2 and the catalytic converter 3. It is supported.
상기 배기매니폴드(2)와 촉매변환기(3), 그리고 배기파이프(4)는 전체 윤곽이 대략 ㄴ자를 형성하도록 배치되며 각각의 부재(2)(3)(5)들은 가스켓(6)(7)을 개재하여 플랜지(8)(9)에 의해 타측부재와 상호 볼트체결되어 접속하고 있다.The exhaust manifold 2, the catalytic converter 3, and the exhaust pipe 4 are arranged so that the entire contour is approximately N-shaped, and each of the members 2, 3, 5 is a gasket 6, 7. ) Is bolted to and connected to the other member by the flanges (8) and (9).
상기 촉매변환기(3)의 후단측 플랜지(9)는 배기파이프(4) 선단의 스프링 커플링(10)과 접속되어지며 상기 스프링커플링(10)은 전후 좌우 방향으로의 굽힘이 자재로운 스프링몸체(11)와 스프링몸체(11) 양단의 플랜지(12)(13)로 구성된다.The rear flange 9 of the catalytic converter 3 is connected to the spring coupling 10 at the front end of the exhaust pipe 4, and the spring coupling 10 has a spring body that can be bent in the front and rear directions. (11) and the flanges 12, 13 at both ends of the spring body (11).
상기 스프링 커플링(10)의 일측 플랜지(13)는 배기파이프(4)에 용접 또는 플랜지 체결에 의해 고정되어지고 타측플랜지(12)는 촉매변환기(3)의 플랜지(9)와 맞대고 볼트 체결하여 접속하며 그 사이에는 가스 누설을 방지하기 위해 가스켓(7)이 삽입된다.One flange 13 of the spring coupling 10 is fixed to the exhaust pipe 4 by welding or flange fastening and the other flange 12 is bolted against the flange 9 of the catalytic converter 3 A gasket 7 is inserted in between to connect and prevent gas leakage.
또한 상기 스프링몸체(11)는 매우 탄력적일 뿐 아니라 매우 긴밀하게 밀착되어 있으며 양측 플랜지(12)(13)를 연결하는 원통형의 내열성 포직물(도시생략)속에 가스누설을 방지토록 수용되어질 수 있다.In addition, the spring body 11 is not only very elastic but also very tightly coupled and can be accommodated to prevent gas leakage in a cylindrical heat-resistant fabric (not shown) connecting both flanges 12 and 13.
이와같이 구성된 본 고안은 배기가스의 고열에 의해 배기매니폴드(2)와 촉매변환기(3)가 각기 열팽창에 의해 상하 방향에서 플랜지(8)부에 압력을 가하게 될 때 종래의 경우 배기파이프(4)가 고정지지부재(5)에 의해 고정되어 있기 때문에 열팽창을 흡수할 수 없어 접속되는 플랜지(8)부가 파손되어 가스누설이 발생하게 되는데 반하여 본 고안은 양측 부재(2)(3)의 열팽창을 스프링커플링(10)의 굽힘 변형을 통하여 흡수하게 되므로 플랜지(8) 접속부위의 손상을 방지할 수 있게 되는 것이다.According to the present invention, the exhaust manifold (2) and the catalytic converter (3) exert pressure on the flange (8) in the vertical direction by thermal expansion, respectively, due to the high heat of the exhaust gas. Is prevented from absorbing thermal expansion because it is fixed by the fixed support member 5, and the flange 8 connected to it is broken, causing gas leakage. However, the present invention prevents thermal expansion of both members (2) and (3). Since the absorbing through the bending deformation of the coupling 10 it is possible to prevent damage to the flange (8) connection.
이상과 같은 본원 고안의 배기장치에 의하면 촉매변환기와 배기파이프를 굽힘이 자재로운 스프링 커플링을 개재시켜 접속하므로써 배기매니폴드와 촉매변환기의 열팽창에 의한 양측 부재의 충돌을 방지하고 그 변형량을 스프링 커플링에서 흡수토록 하고 있기 때문에 플랜지 접속부위의 파손을 방지하여 내구성을 향상시키는 효과가 있게 된다.According to the exhaust device of the present invention as described above, by connecting the catalytic converter and the exhaust pipe through a spring coupling which is flexible, the collision of both members due to thermal expansion of the exhaust manifold and the catalytic converter is prevented, and the amount of deformation is the spring couple. Since it is absorbed by the ring, it is effective in preventing durability of the flange connection and improving durability.
