본 발명은 배기계와 실린저 블록 사이에 설치되는 스테이의 구조를 변경하여 엔진 작동시 진동하중을 전달받는 배기계를 지지하는 스테이에 발생하는 굽힘 반복하중에 의한 파손을 방지하고, 상기 스테이에 설치되는 볼트가 풀리는 현상을 방지하여 사용할 수 있는 배기계 스테이 구조에 관한 것이다.The present invention changes the structure of the stay installed between the exhaust system and the cylinder block to prevent breakage due to repeated bending loads generated in the stay supporting the exhaust system receiving the vibration load during the operation of the engine, and bolts installed in the stay The present invention relates to an exhaust system stay structure that can be used to prevent the phenomenon of loosening.

일반적으로, 차량에 설치된 엔진의 실린더 내부에서 가솔린 또는 경유가 연소된 후에 상기 실린더에서 가스가 배출되어 배기관을 통해 배기 가스가 대기중으 로 방출된다.In general, after gasoline or diesel is combusted in a cylinder of an engine installed in a vehicle, gas is discharged from the cylinder and exhaust gas is discharged into the atmosphere through an exhaust pipe.

첨부된 도 1에 도시된 바와 같이, 일반적인 차량의 배기계(2)는 실린더헤드(1)와 연결 설치되는 배기매니폴드(2a)와, 상기 배기매니폴드(2a)의 하단에 연결되어 배기가스에서 배출되는 CO, HC, NOx등의 유해한 가스를 산화 환원반응을 통하여 무해한 가스로 변환하는 촉매변환기(2b)와, 상기한 촉매변환기(2b)와 연결되어 무해한 가스를 대기중으로 방출하는 배기파이프(미도시)와 상기 실린더 블록(4)과 촉매변환기(2b) 사이에 설치되어 상기 배기계(2)를 지지하는 스테이(2c)를 포함하여 구성된다.As shown in FIG. 1, the exhaust system 2 of a general vehicle is connected to an exhaust manifold 2a that is installed in connection with a cylinder head 1, and is connected to a lower end of the exhaust manifold 2a to exhaust gas from the exhaust gas. Catalytic converter 2b for converting the harmful gases such as CO, HC, NOx discharged into harmless gas through redox reaction, and exhaust pipe connected with the catalytic converter 2b to discharge harmless gas into the atmosphere And a stay (2c) provided between the cylinder block (4) and the catalytic converter (2b) for supporting the exhaust system (2).

상기한 배기계(2)는 열충격 하중과 엔진으로부터 전달되는 진동하중에 대해 지속적으로 영향을 받기 때문에 적정한 강성 유지가 필요하다.Since the exhaust system 2 is continuously affected by the thermal shock load and the vibration load transmitted from the engine, it is necessary to maintain proper rigidity.

상기 배기계(2)는 엔진 작동시에 고온상태에서 상하방향으로 팽창하면서 진동하중을 받기 때문에 상기 배기계(2)를 지지하는 스테이(2c)는 전후좌우 방향에 대한 충분한 강성을 가져야하며, 상하방향에 대한 열변형에 의한 구속에 대한 파손을 방지하기 위해 일정량의 유연성(Flexibility)를 가져야 한다.Since the exhaust system 2 receives the vibration load while expanding in the vertical direction at a high temperature during engine operation, the stay 2c supporting the exhaust system 2 should have sufficient rigidity in the front, rear, left, and right directions, and It must have a certain amount of flexibility to prevent damage to restraint caused by thermal deformation.

그러나, 실제 차량에 설치되어 사용되는 일반적인 스테이는 상기 배기계(2)의 열변형 및 진동하중에 의해 상기 스테이(2c)가 설치된 실린더 블록(4)의 체결부에서는 인장력과 굽힘모멘트를 동시에 받게된다.However, a general stay installed and used in an actual vehicle receives both a tensile force and a bending moment at the fastening portion of the cylinder block 4 in which the stay 2c is installed due to the heat deformation and vibration load of the exhaust system 2.

또한, 상기 체결부의 접촉면에 설치된 볼트가 상기 인장력 또는 굽힘모멘트에 의해 체결상태가 해제되어 볼트가 풀리는 현상이 쉽게 발생되는 문제점이 있으며, 상기 볼트가 체결부상에서 미안착되는 현상이 발생되었다.In addition, there is a problem that the bolt is installed on the contact surface of the fastening portion is released by the tension force or bending moment, the bolt is easily released, the bolt is unsettled on the fastening portion.

상기한 스테이(2c)는 굽힘모멘트에 의한 반복 하중에 상당히 취약한 구조로 되어 있어서 쉽게 파손이 발생되는 문제점이 야기되었다.The stay 2c has a structure that is quite vulnerable to the repetitive load caused by the bending moment, causing a problem that breakage occurs easily.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 기존의 배기계를 지지하기 위해 설치되는 스테이의 구조를 변경하고, 상기 배기계와 실린더 블록 사이에 평행하게 설치하여 굽힘모멘트에 의한 스테이의 변형을 방지하여 사용할 수 있는 배기계 스테이 구조를 제공 하는데 그 목적이 있다.The present invention has been made to solve the above problems, the structure of the stay is installed to support the existing exhaust system, and installed in parallel between the exhaust system and the cylinder block to prevent deformation of the stay by the bending moment The purpose is to provide an exhaust system stay structure that can be used.
