이하 본 발명의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명에 의한 머플러장치의 평단면도이고, 도 2는 본 발명에 의한 머플러장치의 측단면도이다.1 is a plan sectional view of a muffler device according to the present invention, and FIG. 2 is a side sectional view of a muffler device according to the present invention.

본 발명의 머플러장치(1)는 강관으로 된 원통체(2)와 전방 및후방벽부재(3)(4), 보강배플(5), 배기가스유입파이프(6), 배기가스유출파이프(7) 및 연통파이프(8)를 포함하여 구성되어 있다.The muffler device 1 of the present invention is a cylindrical body 2 made of steel pipe and the front and rear wall members (3) (4), reinforcement baffle (5), exhaust gas inlet pipe (6), exhaust gas outlet pipe (7) And a communication pipe 8.

원통체(2)의 배기가스유입파이프(6)의 선단부(6a)는 전방배기파이프에 접속되고 그의 후단 개방부(9)는 전후방벽부재(3)(4)를 관통하여 제3공간(12)에 노출되어 있다.The front end 6a of the exhaust gas inflow pipe 6 of the cylindrical body 2 is connected to the front exhaust pipe, and the rear end opening 9 thereof penetrates the front and rear barrier members 3 and 4 to form a third space 12. ) Is exposed.

상기 연통파이프(8)는 제2공간(11)과 제3공간(12)을 연통하도록 후방벽부재(4)에 고정지지되고 있다.The communication pipe 8 is fixed to the rear wall member 4 so as to communicate the second space 11 and the third space 12.

그리고 상기 배기가스유출파이프(7)는 출구파이프(13)와 본체파이프(14)가 U자형관(15)에 의해 연결된 형태로서 출구파이프(13)의 일측개방단부(13a)는 상기 제2공간(11)에 노출되어 있다.In addition, the exhaust gas outlet pipe 7 has a form in which the outlet pipe 13 and the main body pipe 14 are connected by a U-shaped pipe 15, and one open end 13a of the outlet pipe 13 is the second space. Exposed to (11).

또 상기 출구파이프(13)는 도 2에서와 같이 원통체(2)의 바닥면(2a) 가까이에 수평으로 배설되며, 그로부터 연장된 U자형관(15)은 상향경사지게 뻣어나간후 출구파이프(13)보다 높은 위치를 가지는 본체파이프(14)에 접속되며, 이로써 배기가스는 U자형관(15)에 의해 그의 흐름이 180°로 방향 전환된다.In addition, the outlet pipe 13 is horizontally disposed near the bottom surface 2a of the cylindrical body 2, as shown in FIG. 2, and the U-shaped pipe 15 extending therefrom is stiffened upwardly and then the outlet pipe 13 Is connected to the main pipe 14 having a position higher than), whereby the exhaust gas is diverted by 180 degrees by the U-shaped pipe 15.

그리고 제1공간(10)을 통과하여 지나는 배기가스유입파이프(6)의 부분에는 구멍(16)이 형성되어 배기가스가 그 구멍(16)을 통해 제1공간(10)으로 드나들기 때문에 공명실의 역할을 하여 소음을 감쇄시키게 된다.A hole 16 is formed in the part of the exhaust gas inflow pipe 6 passing through the first space 10 so that the exhaust gas enters the first space 10 through the hole 16 and thus the resonance chamber. It acts as a damper for noise.

상기 보강배플(5)은 U자형단면(5a)을 부분적으로 가지고 있으며, 제2공간(11)내에 위치하도록 원통체(2)에 설치되나 제2공간(11)을 구획하지는 아니한다.The reinforcement baffle 5 partially has a U-shaped cross section 5a and is installed in the cylindrical body 2 so as to be located in the second space 11, but does not partition the second space 11.

이와같은 본 발명은 전방배기파이프(6)에 접속된 배기가스유입파이프(6)를 통해 제3공간(12)에 유입된 배기가스는 확산에 의해 압력이 저하되고 또 온도가 강하되며 다시 연통파이프(8)를 통하여 제2공간(11)으로 유입되면서 압력과 온도가 낮아지게 된다.In the present invention as described above, the exhaust gas introduced into the third space 12 through the exhaust gas inlet pipe 6 connected to the front exhaust pipe 6 is reduced in pressure due to diffusion, and the temperature is lowered. The pressure and temperature are lowered while entering the second space 11 through (8).

압력과 온도가 저하된 제2공간(11)내의 배기가스는 출구파이프(13), U자형관(15) 및 본체파이프(14)순으로 구성된 배기가스유출파이프(7)를 통하여 최후방의 테일파이프로 보내지며, 그 테일파이프를 거쳐 대기중에 배출된다.The exhaust gas in the second space 11 in which the pressure and the temperature are reduced is the tail pipe of the rearmost portion through the exhaust gas outlet pipe 7 composed of the outlet pipe 13, the U-shaped pipe 15, and the main body pipe 14. Is discharged to the atmosphere via the tailpipe.

이때 외기와의 온도 차이에 따라 배기가스유출파이프(7)내에 응축수가 생기게 되는데 이 응축수는 U자형관(15)을 통해 위치에너지가 낮은 출구파이프(13)측으로 흘러 바닥면(2a)으로 떨어져 회수된다.At this time, condensate is generated in the exhaust gas outlet pipe 7 according to the temperature difference between the outside air, and the condensate flows through the U-shaped pipe 15 toward the outlet pipe 13 having a low potential energy and is recovered to the bottom surface 2a. do.

또 본체파이프(14)에는 제2공간(11)과 제3공간(13)에 걸쳐 공간(17)을 두고 덮개관(18)이 장착되고, 덮개관(18)의 장착 부위에는 수많은 구멍(19)이 천공되어 있다.In addition, the cover pipe 18 is mounted in the main pipe 14 with the space 17 over the second space 11 and the third space 13, and a large number of holes 19 are provided in the mounting portion of the cover pipe 18. ) Is perforated.

특히, 상기한 보강배플의 형성위치는 전방벽부재와는 85mm 거리가 되며, 후방벽부재와는 140mm 거리가 되는 지점에 형성되는 것을 바람직하다.In particular, the formation position of the reinforcement baffle is preferably 85mm distance from the front wall member, it is preferably formed at a point that is 140mm away from the rear wall member.

이와같은 본 발명은 배기가스 유출파이프(7)가 본체파이프(14), U자형관(15) 및 출구파이프(13)로 연속되게 구성되어 테일파이프에 접속되므로 테일파이프의 전체 길이의 실질적 증가를 가져와 저주파 부밍 소음 감쇄에 효과가 있게 되는 것이다.In the present invention, since the exhaust gas outlet pipe 7 is continuously composed of the main pipe 14, the U-shaped pipe 15, and the outlet pipe 13 and connected to the tail pipe, a substantial increase in the overall length of the tail pipe is achieved. It is effective in reducing low frequency booming noise.

또 원통체(2)는 종래에는 단순한 타원형으로 형성되어 차량 후방에서의 시각적 심미감이 밋밋한데 비하여 본 발명의 경우 단면 형상이 복잡(상하가 다름)하여 심미감을 높이고 있다(도 2 참조).In addition, the cylindrical body 2 is conventionally formed in a simple elliptical shape, and the visual aesthetics of the rear of the vehicle are insignificant, whereas in the present invention, the cross-sectional shape is complicated (upper and lower sides) to enhance the aesthetics (see FIG. 2).

이상과 같은 본 발명은 테일파이프에 접속되는 원통체내의 배기가스 유출파이프를 U자형 관체로 형성하여 전체 길이를 연장하므로써 저주파 부밍 소음의 감쇄 효과를 얻을 수 있으며, 또 배기가스 유출파이프와 배기가스 유입 단부측은 위치가 낮고 본체 파이프측은 높게 형성하여 외부와의 온도차에 의해 발생한 응축수가 U자형 관에 의해 낮은 위치인 출구파이프로 흘러 원통체의 바닥면에 떨어지게 되므로 응축수의 배출성이 향상되며 또 보강 배플로 인하여 원통체의 강도가 보강되고 원통케이스에 의한 방사음을 저감시키게 되는 효과가 있다.According to the present invention as described above, the exhaust gas outflow pipe in the cylindrical body connected to the tail pipe is formed into a U-shaped tube to extend the overall length, thereby reducing the effect of low frequency booming noise, and exhaust gas outflow pipe and exhaust gas inflow. The end side has a low position and the main body pipe side is formed so that the condensed water generated by the temperature difference with the outside flows into the outlet pipe, which is a low position by the U-shaped pipe, and drops to the bottom surface of the cylindrical body. Due to this, the strength of the cylindrical body is reinforced and the effect of reducing the radiation caused by the cylindrical case is reduced.
