Description
본 고안은 배기매니폴드와 촉매변환기의 접속플랜지부의 열팽창에 의한 가스누설을 방지하기 위한 배기파이프의 지지장치에 관한 것이다.The present invention relates to an apparatus for supporting an exhaust pipe for preventing gas leakage due to thermal expansion of the connection flange portion of the exhaust manifold and the catalytic converter.
종래 배기가스 배출장치는 도 4에 도시하는 것과같이 실린더헤드의 배기포트부에 접속되는 배기매니폴드(1)와 배기매니폴드(1)에 접속되는 촉매변환기(2) 및 촉매변환기(2)의 후단에 접속되는 배기파이프(3)등으로 구성되어 있다.Conventionally, the exhaust gas discharge device includes an exhaust manifold 1 connected to an exhaust port portion of a cylinder head and a catalytic converter 2 and a catalytic converter 2 connected to the exhaust manifold 1, as shown in FIG. The exhaust pipe 3 etc. connected to the rear end are comprised.
또한 배기파이프(3)는 차체를 따라 길게 연장되기 때문에 실린더블록(10)에 지지부재(9)를 통해 움직이지 않도록 고정되어 있다.In addition, since the exhaust pipe 3 extends long along the vehicle body, the exhaust pipe 3 is fixed to the cylinder block 10 so as not to move through the support member 9.
그러나 상기한 배기가스 배출장치는 전체가 L자 형상으로 구부러져 고정되어 있으며 배기매니폴드(1)와 촉매변환기(2, Closed Coupled Catalytic Converter)의 질량이 커서 고온운전시 양측부재(1)(2)를 접속한 플랜지부(5,6)가 상하로 열팽창에 의한 과다한 열적부하를 받기 때문에 플랜지부(5,6)의 틈새가 벌어지고 가스켓(4)이 반복되는 압축팽창에 의해 손상되므로써 배기가스가 누설되는 문제점이 발생하고 있다.However, the exhaust gas exhaust device is bent in a L-shape as a whole and is fixed, and the mass of the exhaust manifold 1 and the catalytic converter (2, Closed Coupled Catalytic Converter) is large, so that both members (1) and (2) are operated at high temperature. Of the flanges 5 and 6, which are connected to each other, are subjected to excessive thermal load due to thermal expansion up and down, so that the gap between the flanges 5 and 6 is widened and the gasket 4 is damaged by repeated compression expansion. There is a problem of leakage.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는바는 배기매니폴드와 촉매변환기를 접속하는 접속플랜지부의 열적부하에 의한 손상 및 이에따른 배기가스 누설을 방지할 수 있는 배기장치의 시일성 확보를 위한 배기파이프의 지지장치를 제공하는데 있다.Therefore, the present invention has been proposed in view of the above problems, and an object thereof is an exhaust device capable of preventing damage due to thermal load of the connecting flange portion connecting the exhaust manifold and the catalytic converter and consequent exhaust gas leakage. To provide a support device for the exhaust pipe to ensure the sealing of the.

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 배기파이프 지지장치의 일실시예를 나타내는 도면이며1 is a view showing an embodiment of an exhaust pipe support apparatus according to the present invention;
도 2는 도 1의 A-A 단면도이며2 is a cross-sectional view taken along the line A-A of FIG.

도면에 있어서 부호 1은 실린더헤드에 접속되는 배기매니폴드이며 부호 2는 배기매니폴드(1)에 가스켓(4)을 개재하여 플랜지(5,6) 체결되는 촉매변환기, 부호 3은 상기 촉매변환기(2)에 플랜지(7,8) 접속되는 배기파이프이며 상기 구성의 배기장치의 전체 형상은 대략 ㄴ자 형상을 이룬다.In the drawing, reference numeral 1 denotes an exhaust manifold connected to the cylinder head, numeral 2 denotes a catalytic converter which is fastened to the exhaust manifold 1 via a gasket 4, and flange 3, 6 denotes a catalytic converter ( The exhaust pipes connected to the flanges 7 and 8 are formed in 2), and the overall shape of the exhaust device having the above-described configuration has an approximately C shape.
상기 배기파이프(3)는 차체 길이를 따라 길게 연장되며 질량이 큰 배기매니폴드(1)와 촉매변환기(2)의 하중을 지지하고 진동으로부터의 떨림을 방지하기 위해 지지부재(9)에 의해 실린더블록(10)에 고정지지되어 있다.The exhaust pipe 3 extends along the length of the vehicle body and is supported by the support member 9 to support the load of the large exhaust manifold 1 and the catalytic converter 2 and to prevent shaking from vibration. It is fixedly supported by the block 10.
상기 지지부재(9)의 중간은 절단되고 양측에 플랜지(11,12)를 갖는 나선형 코일 형태의 강성스프링(13)이 플랜지 접속되어 있다.The middle of the support member 9 is cut and a rigid coil 13 in the form of a spiral coil having flanges 11 and 12 on both sides thereof is flanged.
이와같은 본원 고안은 과도한 열적부하가 작용하여 배기매니폴드(1)와 촉매변환기(2)가 반복되는 인장 및 압축작용에 의해 상1Q하1Q좌1Q우로 열팽창 변형되더라도 그 변형량을 배기장치의 전체하중을 지지하고 있는 지지부재(9)의 강성스프링(13)이 흡수하므로 플랜지접속부(5,6)(7,8)의 파손을 방지하여 시일성을 확보하는 효과가 있다.This invention devises that even if the thermal manifold is deformed from the upper 1Q to the lower 1Q left 1Q due to the repeated thermal and compressive action of the exhaust manifold 1 and the catalytic converter 2 due to excessive thermal load, the total amount of deformation of the exhaust system is calculated. Since the rigid spring 13 of the support member 9 for supporting the absorption is absorbed, there is an effect of preventing the breakage of the flange connection portion 5, 6, (7, 8) to ensure the sealability.
