본 고안은 배기매니폴드를 통해 배출되는 유해한 배기가스를 무해한 상태로서 산화, 환원시키도록 하는 캐털리스트(Catalyst, 촉매 컨버터)를 지지시키는 구조에 대한 것으로서, 상세하게는 배기장치에서 캐털리스트를 안전하게 지지되도록 하면서 배기계의 열팽창에 의한 변형을 흡수할 수 있도록 하는 배기장치에서의 캐털리스트 지지구조에 대한 것이다.The present invention relates to a structure for supporting a catalyst (catalytic converter) for oxidizing and reducing harmful exhaust gas discharged through an exhaust manifold as a harmless state, and in detail, safely supports the catalyst in an exhaust system. A catalyst support structure in an exhaust system that is capable of absorbing deformation due to thermal expansion of the exhaust system.

일반적으로 엔진에서 발생되는 배기가스는 인체에 유해난 CO, HC, NO와 같은 불완전연소가스가 대부분이므로 이러한 배기가스를 그대로 대기중으로 배출시키게 되면 환경공해에 대단히 치명적인 영향을 끼치게 되며, 따라서 대기로 배출시키기 전에 이러한 배기가스를 재차 산화 또는 환원을 시킬 필요가 있으므로 별도의 정화장치를 배기장치에 장착시키게 되는 것이다.In general, exhaust gases generated from engines are mostly incomplete combustion gases such as CO, HC, and NO, which are harmful to the human body. If these exhaust gases are emitted into the atmosphere as they are, they have a very harmful effect on environmental pollution. Since the exhaust gas needs to be oxidized or reduced again before it is installed, a separate purification device is installed in the exhaust device.

상기와 같은 유해한 배기가스의 정화를 위해 예전에는 배기파이프의 중간에 캐털리스트를 설치시키곤 하였으나, 정화효율이 미약하고, 특히 최근에는 배기가스에 대한 규제가 대폭 강화되어 배기가스의 정화효율을 대폭 촉진시키기 위해 캐털리스트를 배기매니폴드에 바로 연결시켜 촉매작용을 하도록 하고 있다.In the past, the catalyst was installed in the middle of the exhaust pipe to purify the harmful exhaust gas. However, the purification efficiency is weak. In particular, the regulation on the exhaust gas has been greatly strengthened recently, which greatly promotes the purification efficiency of the exhaust gas. To do this, the catalyst is connected directly to the exhaust manifold for catalysis.

그러나 이렇게 배기매니폴드에 캐털리스트를 바로 연결시키게 되면 캐털리스트의 자체중량에 의해 엔진의 진동시 연결부가 헐거워져 정화되지 않은 가스가 새거나 심하게 요동을 일으키게 되므로 캐털리스트가 쉽게 손상될 수가 있으므로 중량을 최소화시켜야만 가능해지나, 이렇게 작은 사이즈로 형성시키게 되면 그만큼 정화효율이 저하되게 되므로 실용적이지 못하다.However, if the catalyst is directly connected to the exhaust manifold, the connection weight is loosened when the engine vibrates due to the catalyst's own weight, which causes unpurified gas to leak or cause severe fluctuations. It is possible to do this, but if it is formed in such a small size it is not practical because the purification efficiency is reduced by that much.

따라서 보다 충분한 정화효율을 갖는 사이즈의 캐털리스트를 별도의 브라켓으로 실린더블럭과 연결되도록 하기도 하였으나, 이렇게 브라켓을 캐털리스트에 직접 연결시키다보면 캐털리스트 및 배기매니폴드의 열변형에 의해 상기 브라켓의 강도가 약해져 변형이 되거나 파손되기도 하고, 상대적으로 실린더블럭보다 약한 재질인 브라켓이 결착되는 캐털리스트의 케이싱이 손상되어 캐털리스트를 사용불능상태로 되게 하며, 특히 고온의 배기가스가 통과하는 배기매니폴드와 캐털리스트가 전체적으로 실린더블럭으로부터 멀어지게 되는 열팽창이 생기게 되면 상기 브라켓이나 캐털리스트의 케이싱이 파손되는 사례가 많은 문제점이 있는 것이다.Therefore, although the size of the catalyst having a more sufficient purification efficiency is connected to the cylinder block by a separate bracket, when the bracket is directly connected to the catalyst, the strength of the bracket is increased by thermal deformation of the catalyst and the exhaust manifold. It weakens, deforms or breaks, and damages the casing of the catalyst, which is relatively weaker than the cylinder block, and renders the catalyst unusable. In particular, the exhaust manifold and the caterpillar through which high-temperature exhaust gas passes. There are many problems in which the bracket or the casing of the catalyst is broken when the thermal expansion that causes the wrist to move away from the cylinder block as a whole occurs.

또한 상기와 같은 브라켓으로 지지시키게 되는 때에는 캐털리스트의 열변형과 함께 엔진의 심한 진동에 의해서도 상기 브라켓의 변형이 가속화되므로 브라켓이 쉽게 손상되어 잦은 교체를 해야만 하는 문제점도 있는 것이다.In addition, when the bracket is supported by the bracket, the deformation of the bracket is accelerated by the severe vibration of the engine together with the thermal deformation of the catalyst, so that the bracket is easily damaged and frequent replacement is required.

이에 본 고안은 상기한 문제점들을 해소시키고자 안출한 것으로서, 본 고안의 주된 목적은 실린더블럭의 심한 진동에도 캐털리스트를 안전하게 지지될 수 있도록 하기 위한 것이다.The present invention is to solve the above problems, the main purpose of the present invention is to be able to safely support the catalyst even in the severe vibration of the cylinder block.

또한 본 고안의 다른 목적으로는 캐털리스트의 변형을 방지시킬 수 있도록 하는데 있다.In addition, another object of the present invention is to prevent deformation of the catalyst.

상기와 같은 목적에 따른 본 고안의 구성은, 실린더헤드에 체결된 배기매니폴드의 단부로 캐털리스트의 일단부가 체결되도, 그 타단부는 전방 배기파이프의 일단부와 체결되도록 하는 캐털리스트의 장착구성에 있어서,The configuration of the present invention according to the above object, even if one end of the catalyst is fastened to the end of the exhaust manifold fastened to the cylinder head, the other end of the mounting configuration of the catalyst to be fastened to one end of the front exhaust pipe To

전체적으로 반원형상인 일단부는 실린더블럭의 외측면에 고정착설되며, 타단부는 전방 배기파이프의 외주면에 밀착되어 클램프에 의해 압착체결되도록 하여서 되는 것이다.One end of the semi-circular shape as a whole is fixedly installed on the outer surface of the cylinder block, and the other end is in close contact with the outer circumferential surface of the front exhaust pipe so as to be crimped together by a clamp.

상기의 구성을 좀더 상세히 설명하면 다음과 같다.The configuration of the above is described in more detail as follows.

도면 제1도에서 보는 바와 같이 본 고안은 배기매니폴드(40)에 바로 연설되는 캐털리스트(30)를 측단면이 반원형상인 브라켓(10)과 상기 브라켓(10)를 전방 배기파이프(60)에서 고정시키는 클램프(20)로서 지지될 수 있도록 한 것으로서 상기 브라켓(10)은 일단부가 실린더블럭(50)에 고정착설되도록 하고, 타단부는 상기 전방 배기파이프(60)의 외주면으로 밀착되도록 한 후 환상의 클램프(20)를 일측에서 보울트로 체결시켜 고정되도록 하는 구도이다.As shown in FIG. 1, the present invention provides a bracket 30 directly speaking to the exhaust manifold 40, and a bracket 10 having a semicircular side surface, and the bracket 10 from the front exhaust pipe 60. FIG. The bracket 10 is to be supported as a clamp 20 to be fixed so that one end is fixedly installed in the cylinder block 50, the other end is in close contact with the outer peripheral surface of the front exhaust pipe 60 and then annular The clamp 20 is a composition to be fixed by fastening with a bolt on one side.

즉 도면 제2도에서 보는 바와 같이 상기 브라켓(10)은 측면 전체형상이 반원형상인 탄성을 갖는 금속박판인 지지플레이트로서, 일단부는 절곡시켜 실린더블럭(50) 외주면에 나사결합시키고, 타단부는 전방 배기파이프(60)의 외주면으로 밀착되도록 하는 호형의 확개부(12)가 형성된 형상이다.That is, as shown in FIG. 2, the bracket 10 is a support plate which is a metal thin plate having an elastic shape having a semi-circular side shape, one end of which is screwed to the outer peripheral surface of the cylinder block 50, and the other end is front. It is a shape in which the arc-shaped expansion part 12 is formed in close contact with the outer circumferential surface of the exhaust pipe 60.

또한 상기 클램프(20)는 도면 제3도의 일실시예에서 보는 바와 같이 단면이 원형인 박판을 일측에서 양단부를 외측으로 나란히 절곡시켜 서로 관통되는 보울트구멍을 천공시킨 조임수단으로서, 전방 배기파이프(60)의 외주면에 상기 브라켓(10)의 타단부를 밀착되도록 한 후 그 단부와 전방 배기파이프(60)의 주면 위로 환설되도록 한 후 일측의 절곡단부(21)로 보울트를 체결하여 양 절곡단부(21)의 간격을 더욱 좁혀지게 하면서 상기 배기파이프(60)에 압착도정될 수 있도록 한 것이다.In addition, the clamp 20 is a fastening means for punching the bolt holes penetrating each other by bending a thin plate having a circular cross section side by side from one side to the outside as shown in the embodiment of FIG. 3, the front exhaust pipe 60 After the other end of the bracket 10 is in close contact with the outer circumferential surface of the ()) and then turned over the main surface of the end and the front exhaust pipe (60) and then fastened the bolt to the bent end 21 of one side both ends of the bent (21) By narrowing the gap between the) and to be compressed and clamped to the exhaust pipe (60).

상기 구성에 따른 본 고안의 작용 및 효과를 설명하면 본 고안은 배기가스를 정화시키기 위한 캐털리스트(30)를 배기매니폴드(40)에 직접 연결시키도록 되는 배기장치의 구조에서 상기 캐털리스트(30)를 안전하게 지지될 수 있도록 하는 지지수단인 브라켓(10)과 상기 브라켓(10)을 고정시키는 클램프(20)를 실린더블럭(50)과 전방 배기파이프(60)로 착설토록 하여서 되는 구조이다.Referring to the operation and effect of the present invention according to the above configuration, the present invention is the catalyst 30 in the structure of the exhaust device to directly connect the catalyst 30 for purifying the exhaust gas to the exhaust manifold 40 ) And a clamp 10 for fixing the bracket 10 and the clamp 20 for fixing the bracket 10 to the cylinder block 50 and the front exhaust pipe 60.

즉 측면형상이 반원형상인 브라켓(10)의 일단부는 실린더블럭(50)에 고정착설되도록 하고, 타단부는 전방 배기파이프(60)의 외주면에 밀착되어 클램프(20)에 의해서 압착고정되도록 하여 엔진이 심하게 진동하더라도 반원형상의 브라켓(10) 본체(11)의 탄성에 의해서 어느쪽방향에서의 진동에서도 충격이 흡수될 수 있게 되는 것이며, 고온의 열과 직접적으로 접촉되지 않는 구성이므로 본 고안의 브라켓(10)이나 클램프(20)의 변형등을 방지할 수가 있는 것이다.That is, one end of the bracket 10 having a semicircular side shape is fixed to the cylinder block 50, and the other end is pressed against the outer circumferential surface of the front exhaust pipe 60 to be crimped and fixed by the clamp 20. Even if severely vibrated, the shock of the semicircular bracket 10 may be absorbed by the elasticity of the main body 11 in any direction, and the bracket 10 according to the present invention is not directly contacted with high temperature heat. Or deformation of the clamp 20 can be prevented.

따라서 브라켓(10)의 고정상태를 견고하게 유지시킬 수가 있게 되며, 특히 체결성을 향상시키게되는 장점이 있는 것이다.Therefore, the fixing state of the bracket 10 can be maintained firmly, in particular, there is an advantage of improving the fastening property.

또한 캐털리스트(30)에 직접 브라켓을 체결시켜 지지토록 하므로서 상기 캐털리스트(30)의 과열에 의해 브라켓이 손상되게 되는 종래의 캐털리스트 지지구조에 비해 본 고안은 지지수단인 브라켓(10)를 실린더블럭(50)과 전방 배기파이프(60)에 걸쳐 설치되도록 하여 직접적인 열의 영향으로부터 벗어나도록 하므로서 변형이나 파손을 방지시키며, 특히 상기 브라켓(10)의 본체(11)를 반원의 탄성을 갖는 금속재의 플레이트구조로 되도록 하여 엔진의 심한 요동시에도 진동충격을 감쇄시키도록 하여 캐털리스트(30)가 안전하게 지지될 수 있도록 한 것이다.In addition, compared to the conventional catalyst support structure in which the bracket is damaged by overheating of the catalyst 30 by fastening the bracket directly to the catalyst 30, the present invention provides a cylinder for supporting the bracket 10 as a support means. It is installed over the block 50 and the front exhaust pipe 60 to prevent deformation or breakage by deviating from the direct heat effect. In particular, the main body 11 of the bracket 10 has a semicircular elastic plate. The structure is to reduce the vibration shock even when the engine is severely swinging so that the catalyst 30 can be safely supported.

그러므로 본 고안은 캐털리스트(30)를 안전하게 지지되도록 하면서 견고한 결착상태를 유지되도록 함과 동시에 엔진의 과열현상이 방지되며, 지지수단도 최초 체결상태대로 유지 보호될 수 있도록 한 구조인 것이다.Therefore, the present invention is to ensure that the catalyst 30 is securely supported while maintaining a solid binding state and at the same time to prevent overheating of the engine, the support means is also a structure that can be maintained and protected in the initial fastening state.

또한 일단 실린더블럭(50)에 보울트결합공만 형성시키게 되면 상기 지지수단을 매우 쉽게 장착시킬 수가 있으므로 체결성이 우수하고, 장시간 사용에 따른 브라켓(10)의 교체가 용이하고 편리한 고안인 것이다.In addition, once only the bolt coupling hole is formed in the cylinder block 50, the support means can be mounted very easily, and thus, the fastening property is excellent, and the replacement of the bracket 10 for a long time is easy and convenient.
