Description
본 발명은 배기 메니폴드와 웜업 카탈리스트 셸 간의 결합 구조에 관한 것으로서, 종래에 배기 메니폴드와 웜업 카탈리스트 셸 간의 접촉 구조상 두 번의 용접을 하여 결합시키던 불편함을 해소하고자, 배기 메니폴드와 웜업 카탈리스트 셸 간의 구조를 변경하여 한 번의 용접으로 결합시킬 수 있도록 한 배기 메니폴드와 웜업 카탈리스트 셸 간의 결합 구조에 관한 것이다.The present invention relates to a coupling structure between an exhaust manifold and a warm-up catalyst shell, and to change the structure between the exhaust manifold and the warm-up catalyst shell in order to solve the inconvenience of combining the welding manifold and the warm-up catalyst shell by welding two times. And a coupling structure between the exhaust manifold and the warm-up catalyst shell, which can be joined by one welding.
통상적으로 엔진의 배기메니폴드에는 웜업 카탈리스트가 용접으로 결합되는데, 즉 웜업 카탈리스트의 최외곽을 이루는 셸의 상단부와 배기메니폴드의 하단부가 용접으로 결합된다.Typically, a warmup catalyst is welded to the exhaust manifold of the engine, that is, the upper end of the outer shell and the lower end of the exhaust manifold are welded.
여기서, 종래의 배기 메니폴드와 웜업 카탈리스트 셸 간의 결합 구조를 첨부한 도 2를 참조로 설명하면 다음과 같다.Herein, referring to FIG. 2 attached to a coupling structure between a conventional exhaust manifold and a warm-up catalyst shell, the following description will be made.
상기 배기메니폴드(10)의 하단 외측면에는 직각으로 절개된 밀착면(24)이 형성되어 있고, 상기 웜업 카탈리스트 셸(12)의 상단부는 만곡되게 이중 굴곡 처리된 절곡단(18)으로 형성되어 있다.The bottom outer surface of the exhaust manifold 10 is formed with a contact surface 24 cut at right angles, the upper end of the warm-up catalyst shell 12 is formed of a bent end 18 bent in a double bent to be curved. .
따라서, 상기 배기 메니폴드(10)의 하단 외측면의 밀착면(24)에 상기 셸(12)절곡단(18)을 밀착시키는 바, 이 밀착된 부분이 결합을 위한 용접부(28)가 된다.Accordingly, the bent end 18 of the shell 12 is brought into close contact with the close contact surface 24 of the lower outer surface of the exhaust manifold 10, and the close contact portion is a weld 28 for engagement.
한편, 상기 배기 메니폴드(10)의 하단끝은 셸(12)과 서포터(14)에 의하여 감싸여져 있는 촉매담체(14)의 상면 테두리와 일치하되, 닿지 않은 상태가 된다.On the other hand, the lower end of the exhaust manifold 10 coincides with the top edge of the catalyst carrier 14 wrapped by the shell 12 and the supporter 14, but is not in contact.
이때, 상기 용접부(28)는 이중 굴곡된 셸(12)의 상단부 형상에 의하여 곡선으로 이루어져 있기 때문에 용접부 면적이 넓고, 그에 따라 한 번에 용접이 이루어지지 않고 두 번에 걸쳐 용접 작업을 실시하여야 하는 작업상 불편함이 있었다.At this time, since the weld 28 is curved by the shape of the upper end of the double bent shell 12, the weld area is large, and thus welding is not performed at one time and the welding operation should be performed twice. There was work inconvenience.
또한, 상기 배기 메니폴드(10)의 하단끝은 촉매담체(14)의 상면 테두리와 닿아 있지 않기 때문에 서포터(16)의 상면이 노출되는 바, 배기 메니폴드(10)내의 배기가스가 서포터(16)쪽으로 흘러 서포터의 내구성을 떨어뜨리는 단점이 있었다.In addition, since the lower end of the exhaust manifold 10 does not contact the upper edge of the catalyst carrier 14, the upper surface of the supporter 16 is exposed, so that the exhaust gas in the exhaust manifold 10 is directed toward the supporter 16. There was a drawback to reduce the durability of the supporter.
따라서, 본 발명은 상기와 같은 점을 감안하여, 배기 메니폴드와 웜업 카탈리스트 셸 간의 접촉 구조를 용접 면적을 크게 줄여주는 면적으로 개선하여 용접을 한 번만 실시하여 배기 메니폴드와 웜업 카탈리스트 셸이 용이하게 결합되도록 하고, 배기가스가 서포터로 흐르지 않도록 배기메니폴드의 하단끝이 촉매담체의 상면에 밀착되게 하여 종래의 서포터의 내구성 저하를 방지할 수 있도록 한 배기 메니폴드와 웜업 카탈리스트 셸 간의 결합 구조를 제공하는데 그 목적이 있다.Accordingly, in view of the above, the present invention improves the contact structure between the exhaust manifold and the warm-up catalyst shell to an area that greatly reduces the welding area, so that the exhaust manifold and the warm-up catalyst shell are easily combined by performing the welding once. In addition, the lower end of the exhaust manifold is in close contact with the upper surface of the catalyst carrier so that the exhaust gas does not flow to the supporter to provide a coupling structure between the exhaust manifold and the warm-up catalyst shell to prevent the durability of the conventional supporter. have.

상기한 목적을 달성하기 위한 본 발명은 배기 메니폴드(10)와 웜업 카탈리스트 셸(12)간의 결합 구조에 있어서, 상기 배기 메니폴드(10)의 하단끝을 상기 셸(12)과 서포터(16)로 둘러싸인 촉매담체(14)의 상면에 밀착되게 연장시키는 동시에 직각의 밀착면(24)이 오목하게 형성된 배기 메니폴드(10)의 하단 외측면을 외부로 만곡되게 돌출시키고, 상기 셸(12)의 이중 굴곡되어 있던 상단끝을 제거하여 직선의 밀착단(20)으로 만들어 주어서, 상기 셸(12)의 밀착단(20)과 상기 배기 메니폴드(10)의 밀착면(24)이 밀착되어 만들어진 용접부(28) 면적을 줄여준 것을 특징으로 한다.The present invention for achieving the above object in the coupling structure between the exhaust manifold 10 and the warm-up catalyst shell 12, the lower end of the exhaust manifold 10 is surrounded by the shell 12 and the supporter 16 While extending in close contact with the upper surface of the catalyst carrier 14 and at the same time the perpendicular contact surface 24 protrudes outwardly the bottom outer surface of the exhaust manifold 10 is formed concave, the double bent of the shell 12 The upper end part was removed to make a straight contact end 20, whereby the contact part 20 of the shell 12 and the contact surface 24 of the exhaust manifold 10 were brought into close contact with each other. Characterized by reduced.
여기서 본 발명을 실시예로서, 첨부한 도면을 참조로 더욱 상세하게 설명하면 다음과 같다.Herein, the present invention will be described in more detail with reference to the accompanying drawings.
첨부한 도 1은 본 발명에 따른 배기 메니폴드와 웜업 카탈리스트 셸 간의 결합 구조를 나타내는 단면도로서, 도면부호 10은 배기 메니폴드이다.1 is a cross-sectional view illustrating a coupling structure between an exhaust manifold and a warm-up catalyst shell according to the present invention, and reference numeral 10 denotes an exhaust manifold.
상기 배기 메니폴드(10)의 출구는 웜업 카탈리스트와 결합되는데, 좀 더 상세하게는 배기 메니폴드(10)의 하단끝과 웜업 카탈리스트의 셸(12) 상단부가 접촉되어 용접으로 결합된다.The outlet of the exhaust manifold 10 is coupled with a warm-up catalyst. More specifically, the lower end of the exhaust manifold 10 and the upper end of the shell 12 of the warm-up catalyst are contacted and welded.
여기서, 상기 배기 메니폴드(10)의 하단끝을 웜업 카탈리스트 셀(12)과 그 안쪽에 위치한 서포터(16)에 의하여 둘러싸인 촉매담체(14)의 상면 테두리에 밀착되게 연장시키는 동시에 그 외측면을 만곡되게 돌출시켜 형성한다.Here, the lower end of the exhaust manifold 10 extends in close contact with the upper edge of the catalyst carrier 14 surrounded by the warm-up catalyst cell 12 and the supporter 16 located therein, and at the same time, the outer surface thereof is curved. Protrude to form.
이때, 상기 만곡되게 돌출된 배기 메니폴드(10)의 하단 외측면에는 직각의 절개된 밀착면(24)이 형성된다.In this case, a right angled cut contact surface 24 is formed on the bottom outer surface of the curved protruding exhaust manifold 10.
한편, 상기 웜업 카탈리스트 셀(12)의 상단부는 상기 밀착면(24)에 밀착되는 밀착단(20)으로 형성되는 바, 종래에 이중으로 굴곡 처리된 밀착단을 제거하여 짧은 길이의 직선 밀착단(20)으로 형성한다.On the other hand, the upper end of the warm-up catalyst cell 12 is formed of a close end 20 in close contact with the contact surface 24, bar is a conventional straight contact end of a short length by eliminating a double bent contact end ( 20).
따라서, 상기 배기 메니폴드(10)의 하단 외측면에 형성된 밀착면(24)에 웜업 카탈리스트 셸(12)의 상단에 형성된 직선의 밀착단(20)을 밀착되게 하는 바, 이 밀착된 부분이 용접부위가 된다.Accordingly, the straight contact end 20 formed at the upper end of the warm-up catalyst shell 12 is brought into close contact with the contact surface 24 formed at the lower outer surface of the exhaust manifold 10. Becomes
이에따라, 상기 밀착면(24)과 밀착단(20)의 밀착부분 즉, 용접부분은 직선 접촉을 하기 때문에 종래의 곡선 처리된 용접부분보다 그 용접면적이 크게 감소되어지고, 그에 따라 한 번의 용접으로 용이하게 결합시킬 수 있게 된다.Accordingly, the contact area of the contact surface 24 and the contact end 20, that is, the welding portion is in linear contact, so that the welding area is significantly reduced compared to the conventional curved welded portion, and accordingly one welding It can be easily combined.
아울러, 상기 배기 메니폴드(10)의 하단끝이 촉매담체(14)의 상면 테두리에 밀착된 상태로 있기 때문에 배기가스가 촉매담체(14)를 둘러싸고 있는 서포터(16)로 흐르지 않게 되어 종래의 서포터 내구성 저하를 방지할 수 있게 된다.In addition, since the lower end of the exhaust manifold 10 is in close contact with the upper edge of the catalyst carrier 14, the exhaust gas does not flow to the supporter 16 surrounding the catalyst carrier 14, thereby supporting conventional supporter durability. The fall can be prevented.
이상에서 본 바와 같이, 본 발명에 따른 배기 메니폴드와 웜업 카탈리스트 셸 간의 결합 구조에 의하면, 종래에 두 번에 걸쳐 실시하던 용접부보다 그 용접면적을 줄여줌으로써, 한 번의 용접작업으로 배기 메니폴드와 웜업 카탈리스트 셸을 결합시킬 수 있고, 아울러 상기 배기 메니폴드의 하단끝이 촉매담체의 상면 테두리에 밀착되게 하여 촉매담체를 둘러싸고 있는 서포터로 배기가스가 흐르지 않게 되어 종래에 배기가스에 의한 서포터 내구성 저하를 방지할 수 있는 장점이 있다.As described above, according to the coupling structure between the exhaust manifold and the warm-up catalyst shell according to the present invention, the exhaust manifold and the warm-up catalyst shell are reduced by one welding operation by reducing the welding area of the welding part which was conventionally performed twice. In addition, the lower end of the exhaust manifold is in close contact with the upper edge of the catalyst carrier so that the exhaust gas does not flow to the supporter surrounding the catalyst carrier to prevent the deterioration of the supporter durability by the conventional exhaust gas There is an advantage.
