도 1은 본 발명에 의한 배기계의 평면도이며, 도 2는 본 발명에 의한 센터머플러의 지지구조를 도시한 단면도로서, 도면부호 12는 배기파이프의 도중에 형성되는 센터머플러이고 도면부호 14는 배기계가 장착되는 차체이다.1 is a plan view of an exhaust system according to the present invention, Figure 2 is a cross-sectional view showing a support structure of the center muffler according to the present invention, reference numeral 12 is a center muffler formed in the middle of the exhaust pipe and 14 is an exhaust system mounted It is a car body.

상기한 센터머플러(12)는 길이가 긴 원통형으로 형성하며, 촉매컨버터(11)의 후단으로 배기파이프(10)의 도중에 형성한다.The center muffler 12 is formed in a long cylindrical shape, and is formed in the middle of the exhaust pipe 10 to the rear end of the catalytic converter 11.

상기한 센터머플러(12)의 후미에 연결되는 배기파이프(10)는 메인머플러(13)의 입력측에 형성되는 입력파이프(13a)와 플랜지결합한다.The exhaust pipe 10 connected to the rear of the center muffler 12 is flanged to the input pipe 13a formed on the input side of the main muffler 13.

그리고 상기와 같이 구성되는 배기계를 차체(14)의 하방에 마운팅하기 위하여 프론트머플러(15)의 전방에 배기계의 전방을 차체에 고정하기 위한 전방장착부(15a)를 형성하고, 상기한 메인머플러(13)의 상부측으로도 상기한 배기계의 후방을 매달기 위한 후방장착부(13b)를 형성한다.Then, in order to mount the exhaust system configured as described above under the vehicle body 14, a front mounting portion 15a is formed at the front of the front muffler 15 to fix the front of the exhaust system to the vehicle body, and the main muffler 13 described above. The rear mounting portion 13b for hanging the rear of the exhaust system is also formed on the upper side of

특히, 상기한 센터머플러(12)가 형성되는 배기계의 중간부를 지지하기 위해서 상기 센터머플러(12)의 도중에는 메인로드(21)를 형성하는데, 상기한 메인로드(21)는 상기 센터머플러(12)를 아래쪽에서 지지하도록 철봉을 상기 센터머플러(12)의 외주연을 따라 일정각도 절곡하고, 상기한 센터머플러(12)와 접하는 일측을 상기 센터머플러(12)의 양측면 하방에 대칭되도록 용접한다.In particular, the main rod 21 is formed in the middle of the center muffler 12 so as to support an intermediate portion of the exhaust system in which the center muffler 12 is formed, and the main rod 21 is the center muffler 12. The iron bar is bent at an angle along the outer periphery of the center muffler 12 so as to support the bottom, and one side contacting the center muffler 12 is welded to be symmetrical to both sides of the center muffler 12 below.

또한, 상기 센터머플러(12)에 용접된 메인로드(21)와 동일선 상으로 보강로드(22)를 용접하는데, 상기한 보강로드(22)도 철봉을 센터머플러(12)의 외주를 따라 일정각도 절곡한 후, 그 일측면은 센터머플러(12)의 양측면 상방에 용접하고 타측면은 상기 메인로드(21)와 용접한다.In addition, the reinforcing rod 22 is welded on the same line as the main rod 21 welded to the center muffler 12. The reinforcing rod 22 also moves the iron rod at a predetermined angle along the outer periphery of the center muffler 12. After bending, one side is welded above both sides of the center muffler 12 and the other side is welded with the main rod 21.

그리고 배기계가 장착되는 차체의 하부에는 별도 형성되는 고무행거(30)를 고정로드(23)로써 장착하는데, 상기한 고정로드(23)는 철봉을 절곡하여 차체에 일면을 용접하여 상기 고무행거(30)가 힌지결합되도록 한다. 특히 상기한 고무행거(30)의 장착은 정면에서 바라볼 때 일정각도(약 40 ~ 50도) 경사지게 형성하는 것이 바람직하다. 또한 상기한 센터머플러(12)를 지지하는 메인로드(21), 보강로드(22), 고무행거(30)는 평면상에서 볼 때 차체의 길이방향과 직각으로 장착되도록 한다.And the lower part of the vehicle body is equipped with the exhaust system is equipped with a rubber hanger 30 is formed separately as a fixed rod 23, the fixed rod 23 is bent the iron bar to weld one surface to the body to the rubber hanger (30) ) Is hinged. In particular, the mounting of the rubber hanger 30 is preferably formed to be inclined at a predetermined angle (about 40 to 50 degrees) when viewed from the front. In addition, the main rod 21, the reinforcing rod 22, the rubber hanger 30 for supporting the center muffler 12 is to be mounted at right angles to the longitudinal direction of the vehicle body in plan view.

상기한 고무행거(30)는 원형이나 타원형으로 중앙부에 완충공(31)을 형성하는 것이 바람직하며, 양측으로는 상기한 메인로드(21)의 일단(21a)과 고정로드(23)의 일단(23a)을 끼우기 위한 결합공(32,33)이 형성된 것이다.The rubber hanger 30 is preferably formed in the center or the buffer hole 31 in a circular or elliptical, both ends one end 21a of the main rod 21 and one end of the fixed rod 23 ( Joining holes (32, 33) for fitting 23a) is formed.

이상과 같이 구성된 본 발명의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the present invention configured as described above are as follows.

센터머플러(12)의 자중에 의한 수직분력과, 메인로드(21) 및 보강로드(22)에 의한 수평분력과, 일정각도로 경사지게 장착되는 고무행거에 의한 분력이 상호작용하여 상기한 센터머플러(12)의 좌우유동이 감소하게 된다.The vertical component due to the weight of the center muffler 12, the horizontal component due to the main rod 21 and the reinforcing rod 22, and the component due to the rubber hanger mounted inclined at a predetermined angle interact with each other. The flow of left and right in 12 is reduced.

또한, 종래처럼 배기파이프에 로드를 연결할 경우보다 센터머플러(12)의 직경이 배기머플러(10)의 직경보다 크기 때문에 메인로드(21)의 길이가 짧아지므로 결합부재의 진동량이 감소되고 그 만큼 소음이 감소하게 된다.In addition, since the diameter of the center muffler 12 is larger than the diameter of the exhaust muffler 10, the length of the main rod 21 is shorter than the case of connecting the rod to the exhaust pipe as in the prior art, so the vibration amount of the coupling member is reduced and the noise is as much as that. This decreases.

이상과 같은 본 발명은 센터머플러를 지지하기 위하여 상기 센터머플러의 측면에 메인로드와 보강로드를 아래위에서 용접결합하고, 상기 메인로드를 차체에 경사지게 장착되는 고무행거의 결합공에 끼움으로서 센터머플러의 자중에 의한 수직분력과, 메인로드 및 보강로드에 의한 수평분력과, 일정각도로 경사지게 차체에 힌지장착되는 고무행거에 의한 분력이 상호작용하여 상기한 센터머플러의 좌우유동이 감소하게 될뿐만 아니라, 종래처럼 배기파이프에 로드를 연결할 경우보다 센터머플러의 직경이 배기머플러의 직경보다 크기 때문에 메인로드의 길이가 짧아지므로 결합부재의 진동량이 감소되고 그 만큼 소음이 감소되는 커다란 효과가 있는 것이다.The present invention as described above welds the main rod and the reinforcing rod on the side of the center muffler from above to support the center muffler, and by fitting the main rod into the coupling hole of the rubber hanger which is inclined to the body of the center muffler The vertical component due to its own weight, the horizontal component due to the main rod and the reinforcing rod, and the component force due to the rubber hanger hinged to the vehicle body inclined at a predetermined angle interact with each other to reduce the left and right flow of the center muffler. Since the diameter of the center muffler is larger than the diameter of the exhaust muffler than the case of connecting the rod to the exhaust pipe as in the prior art, since the length of the main rod is shortened, the amount of vibration of the coupling member is reduced and the noise is reduced as much.
