본 고안은 배기파이프 고정용 이음체에 관한 것으로서, 더욱 상세하게는 배기 매니폴드에 결합된 배기파이프와 서브머플러를 암, 수으로 이루어진 이음체로 고정시킴으로써 배기가스의 누출을 방지함과 동시에 엔진에서 전달되는 진동을 효과적으로 감쇄시킬 수 있도록 한 배기파이프 고정용 이음체에 관한 것이다.The present invention relates to an exhaust pipe fixing joint, and more particularly, by fixing the exhaust pipe and the sub-muffler coupled to the exhaust manifold with a female and male joint to prevent leakage of the exhaust gas and at the same time, it is transmitted from the engine. The present invention relates to an exhaust pipe fixing joint body capable of effectively attenuating vibrations.

일반적으로 자동차 엔진의 실린더내에서 배기행정 후 연소되어 발생된 배기가스를 대기 속으로 유출시키기 위한 배기파이프는 서브머플러와 상호 고정되어 배기 매니폴드(exhaust manifold)으로부터 배출되는 가스를 소음기로 전달하여 온도와 압력을 낮추어 인체에 유해한 성분 및 소음을 저하시키는 역할을 한다.In general, an exhaust pipe for exhausting the exhaust gas generated by combustion after exhausting in a cylinder of an automobile engine into the atmosphere is fixed to a sub-muffler to transfer gas discharged from an exhaust manifold to a silencer. Lowers the pressure and reduces harmful ingredients and noise.

제1도는 배기파이프와 서브머플러를 고정시키는 종래의 플랜지를 나타낸 도면으로서, 실린더에 장착된 배기 매니폴드(도시되지 않음)와 결합되어 차체 하면에 보울트등 적당한 고정부재에 의해 설치된 배기파이프(10)와 이 배기파이프(10)와 연결되는 서브머플러(12)의 일끝단에 관통홀(14a)이 형성된 플랜지(14)가 용접등의 방법에 의해 고정되어 있으며, 상기 플랜지(14) 사이에는 플랜지로 고정된 부위에서 배기가스의 누출이 방지되도록 삽입홀(16a)이 형성된 가스켓(gasket)(16)이 내설되어 있다.FIG. 1 is a view showing a conventional flange for fixing an exhaust pipe and a sub muffler. The exhaust pipe 10 is coupled to an exhaust manifold (not shown) mounted on a cylinder and installed by a suitable fixing member such as a bolt on the lower surface of the vehicle body. And a flange 14 having a through-hole 14a formed at one end of the submuffler 12 connected to the exhaust pipe 10 is fixed by welding or the like, and a flange is formed between the flanges 14 by a flange. A gasket 16 is formed in which an insertion hole 16a is formed to prevent leakage of exhaust gas at a fixed portion.

이와같이 배기파이프(10) 및 서브머플러(12)의 일단부에 고정된 플랜지(14) 사이로 가스켓(16)을 내설시킨 상태에서 플랜지(14)에 형성된 관통홀(14a)과 가스켓(16)의 삽입홀(16a)이 일치되도록 밀착시킨 다음 보울트(18)를 삽입하고 너트(20)로 조여 배기가스를 유출시키는 것이다.The insertion of the through hole 14a and the gasket 16 formed in the flange 14 while the gasket 16 is insulated between the flange 14 fixed to one end of the exhaust pipe 10 and the sub muffler 12 as described above. The holes 16a are brought into close contact with each other, and then the bolt 18 is inserted and the nut 20 is tightened to drain the exhaust gas.

그러나, 상기와 같이 배기파이프와 서브머플러를 플랜지를 밀착시킨 후 보울트로 고정시켰기 때문에 고정작업시 보울트의 조임력 즉, 토오크의 조정이 어려움은 물론 작업공수가 증가되고, 상, 하 보울트의 토오크가 다를때 플랜지 사이에 내설된 가스켓이 편마모되어 배기가스가 누출되며, 엔진에서의 플랜지에 그대로 전달되므로 가스켓의 파손되어 유해성분의 누출로 인해 대기한경을 오염시키는 문제점이 있었다.However, since the exhaust pipe and the sub-muffler were fixed to the bolt after closely contacting the flange as described above, it is difficult to adjust the tightening force of the bolt, that is, the torque during the fixing operation, as well as increase the work labor, and the torque of the upper and lower bolts is different. When the internal gasket between the flange is worn out, the exhaust gas leaks, and as it is delivered to the flange in the engine, there is a problem of polluting the atmospheric environment due to the damage of the gasket and leakage of harmful components.

상기와 같이 구성된 본 고안에 따른 배기파이프 고정용 이음체의 작용효과를 설명하면 다음과 같다.Referring to the effect of the exhaust pipe fixing joint according to the present invention configured as described above are as follows.

배기파이프(30) 외주면에 가공된 나사산(30a)에 탭가공된 제1이음쇠(38)를 조이고, 서브머플러(36)의 나사산(36a)에 제2이음쇠(40)를 조인다.The first fitting 38 tapped on the thread 30a machined on the outer circumferential surface of the exhaust pipe 30 is tightened, and the second fitting 40 is tightened on the thread 36a of the submuffler 36.

이때 상기 제1 및 제2 이음쇠(38)(40)를 배기파이프(30)와 서브머플러(36)에 대해 전방으로 일부 나오도록 조인 상태에서 배기파이프(30)의 단턱부(32)에 서브머플러(36)의 돌출부(34)를 끼움과 동시에 제2이음쇠(40)의 볼록돌기(40a)를 제1이음쇠(38)에 삽입시키면 제1이음쇠(38)의 오목돌기(38a)가 바깥방향으로 벌어지고, 삽입완료후에는 초기상태로 복원되어 볼록돌기(40a)와 접촉하게 된다.In this case, the first and second fittings 38 and 40 are partially joined to the exhaust pipe 30 and the submuffler 36 in a forward direction, and the submuffler to the step portion 32 of the exhaust pipe 30. When the projection 34 of the 36 is inserted and the convex protrusion 40a of the second fitting 40 is inserted into the first fitting 38, the concave protrusion 38a of the first fitting 38 moves outward. After the insertion is completed, the initial state is restored to come into contact with the convex protrusion 40a.

그후, 제1 및 제2 이음쇠(38)(40)를 서로 반대방향으로 회전시키거나 또는 적어도 하나의 이음쇠를 회전시키면, 배기파이프(30)의 단턱부(32)에 서브머플러(36)의 돌출부(34)가 완전하게 끼워지게 되고, 오목돌기(38a)와 볼록돌기(40a)가 견고하게 접촉되어 엔진에서 발생된 전후, 좌우방향의 진동을 감소시킬 수 있는 것이다.Then, when the first and second fittings 38 and 40 are rotated in opposite directions or the at least one fitting is rotated, the protrusion of the submuffler 36 is formed on the stepped portion 32 of the exhaust pipe 30.
