본 발명은 엔진의 배기가스가 배출되는 경로에 장착되어, 배기가스가 통과하면서 기류음과 고주파소음 및 저주파 부밍 소음이 모두 고르게 저감될 수 있도록 함은 물론, 보다 정숙한 차량의 주행감을 확보할 수 있도록 그 소음의 저감도를 극대화 한다.The present invention is mounted on a path through which the exhaust gas of the engine is discharged, so that the airflow, the high frequency noise, and the low frequency booming noise can be evenly reduced as the exhaust gas passes, as well as ensuring a quieter driving comfort. So that the noise reduction is maximized.

도 1을 참조하면, 본 발명 실시예는 중공 파이프 형상으로 길게 형성된 외통(1)과; 상기 외통(1)의 길이방향을 따라 4개의 공간을 구획하도록, 상기 외통(1)의 내부에 차례로 설치된 제1배플(3), 제2배플(5) 및 제3배플(7)과; 상기 제1배플(3)과의 사이에 제1챔버(9)를 형성하도록 상기 외통(1)의 일단부에 결합되는 입구측마감부재(11)와; 상기 제3배플(7)과의 사이에 제4챔버를 형성하도록 상기 외통(1)의 타단부에 결합되는 출구측마감부재(13)와; 상기 입구측마감부재(11)와 제1배플(3) 내지 제3배플(7)을 차례로 관통하도록 설치된 입구파이프(15)와; 상기 제1배플(3) 내지 제3배플(7)과 상기 출구측마감부재(13)를 차례로 관통하도록 설치된 출구파이프(17)와; 상기 제1배플(3)과 제2배플(5)을 관통하여 설치된 중간파이프(19)와; 상기 제1배플(3)과 제2배플(5) 사이의 제2챔버(23)에 채워진 흡음재(21) 를 포함하여 구성된다.Referring to Figure 1, the embodiment of the present invention and the outer cylinder (1) formed long in the shape of a hollow pipe; A first baffle (3), a second baffle (5) and a third baffle (7) sequentially installed in the inside of the outer cylinder (1) so as to partition four spaces along the longitudinal direction of the outer cylinder (1); An inlet side closing member (11) coupled to one end of the outer cylinder (1) to form a first chamber (9) between the first baffle (3); An outlet side closing member (13) coupled to the other end of the outer cylinder (1) to form a fourth chamber between the third baffle (7); An inlet pipe (15) installed to sequentially pass through the inlet side closing member (11) and the first baffle (3) to the third baffle (7); An outlet pipe (17) installed to sequentially pass through the first baffle (3) to the third baffle (7) and the outlet side closing member (13); An intermediate pipe (19) installed through the first baffle (3) and the second baffle (5); And a sound absorbing material 21 filled in the second chamber 23 between the first baffle 3 and the second baffle 5.

상기 흡음재(21)는 유리섬유(Glass Wool)로 이루어지고, 상기 입구측마감부재(11)는 상기 입구파이프(15)만 관통한 상태로 상기 외통(1)의 일측을 막아 밀봉하는 입구측캡으로 이루어지며, 상기 출구측마감부재(13)는 상기 출구파이프(17)만 관통한 상태로 상기 외통(1)의 타측을 막아 밀봉하는 출구측캡으로 이루어져 있다.The sound absorbing material 21 is made of glass wool, and the inlet side closing member 11 is an inlet side cap that seals one side of the outer cylinder 1 while sealing only the inlet pipe 15. The outlet side closing member 13 is formed of an outlet side cap that seals the other side of the outer cylinder 1 while sealing only the outlet pipe 17.

상기 제2챔버(23)를 지나는 상기 입구파이프(15)의 부분에는 상기 제2챔버(23)와 연통되는 제1연통홀(25)이 형성되고, 상기 제2챔버(23)를 지나는 상기 출구파이프(17)의 부분에는 상기 제2챔버(23)와 연통되는 제2연통홀(27)이 형성된다.A portion of the inlet pipe 15 passing through the second chamber 23 is formed with a first communication hole 25 communicating with the second chamber 23, and the outlet passing through the second chamber 23. A second communication hole 27 communicating with the second chamber 23 is formed in a portion of the pipe 17.

엔진으로부터의 배기가스는 상기 입구파이프(15)로 유입되어 흐르면서, 상기 제2챔버(23)를 지날 때 상기 제1연통홀(25)에 의해 기류음이 저감되게 되고, 상기 출구파이프(17)를 통해 소음기의 외부로 배출되는 동안에도 상기 제2챔버(23)를 지날 때 상기 제2연통홀(27)에 의해 그 기류음이 저감되게 된다.The exhaust gas from the engine flows into the inlet pipe 15 and flows through the first communication hole 25 to reduce the airflow sound when passing through the second chamber 23, and the outlet pipe 17. The airflow sound is reduced by the second communication hole 27 when passing through the second chamber 23 even while being discharged to the outside of the silencer.

상기 제1배플(3)에는 상기 제1챔버(9)와 제2챔버(23)를 연통시키는 제3연통홀(29)이 적어도 1개 이상 형성되고, 상기 제2배플(5)에는 상기 제2배플(5)과 제3배플(7) 사이의 제3챔버(31)를 상기 제2챔버(23)와 연통시키는 제4연통홀(33)이 적 어도 1개 이상 형성된다.At least one third communication hole 29 communicating the first chamber 9 and the second chamber 23 is formed in the first baffle 3, and the second baffle 5 is formed in the first baffle 3. At least one fourth communication hole 33 for communicating the third chamber 31 between the second baffle 5 and the third baffle 7 with the second chamber 23 is formed.

상기 제1배플(3)의 제3연통홀(29)과 제2배플(5)의 제4연통홀(33)은 양쪽에서 지저분한 고주파 소음을 저감시키는 역할을 수행한다.The third communication hole 29 of the first baffle 3 and the fourth communication hole 33 of the second baffle 5 serve to reduce dirty high frequency noise at both sides.

상기 입구측마감부재(11)로부터 상기 출구측마감부재(13)까지의 길이를 전체길이라고 할 때, 상기 제2배플(5)은 상기 입구측마감부재(11)로부터 상기 전체길이의 1/2 이내의 위치에 배치되어 있다.When the length from the inlet side closing member 11 to the outlet side closing member 13 is referred to as the total length, the second baffle 5 is one-third of the total length from the inlet side closing member 11. It is arrange | positioned in two or less positions.

따라서, 상기 제2배플(5)의 우측 공간을 충분히 확보할 수 있고, 이는 저주파 소음을 줄일 수 있는 공간을 확보할 수 있도록 해준다.Therefore, the right space of the second baffle 5 can be sufficiently secured, which makes it possible to secure a space for reducing low frequency noise.

상기 제3챔버(31)를 지나는 상기 입구파이프(15)의 부분에는 상기 제3챔버(31)와 연통되는 제5연통홀(35)이 형성되는데, 이는 상기와 같이 크게 확보된 제2배플(5) 우측의 공간에서 저주파 부밍 소음을 효과적으로 저감시키도록 하는 역할을 한다.A portion of the inlet pipe 15 passing through the third chamber 31 is formed with a fifth communication hole 35 communicating with the third chamber 31, which is secured as the second baffle ( 5) It plays a role to effectively reduce low frequency booming noise in the space on the right side.

즉, 상기 제5연통홀(35)에 의해 균일한 배기가스가 지나가면서 저주파음의 반사 현상을 통해 추가적인 소음 저감이 이루어지는 것이다. That is, while the uniform exhaust gas passes by the fifth communication hole 35, additional noise reduction is achieved through the reflection phenomenon of low frequency sound.

상기 제3배플(7)에는 상기 제3챔버(31)와 제4챔버(37)를 연통시키는 제6연통홀(39)이 적어도 1개 이상 형성된 구조이다. 물론, 상기 제4챔버(37)는 상기 제3배플(7)과 상기 출구측마감부재(13) 사이에 형성되는 공간이다.The third baffle 7 has a structure in which at least one sixth communication hole 39 for communicating the third chamber 31 and the fourth chamber 37 is formed. Of course, the fourth chamber 37 is a space formed between the third baffle 7 and the outlet side closing member 13.

따라서, 상기 제3배플(7)의 제6연통홀(39)을 통과하는 소음과 상기 제5연통홀(35)을 통과하는 소음이 서로 간섭하여 소음저감효과를 극대화할 수 있게 된다.Therefore, the noise passing through the sixth communication hole 39 of the third baffle 7 and the noise passing through the fifth communication hole 35 interfere with each other to maximize the noise reduction effect.

상기 제2챔버(23)를 통과하는 상기 중간파이프(19)의 부분에는 상기 제2챔버(23)와 연통되는 제7연통홀(41)이 형성된 구조이다.A portion of the intermediate pipe 19 passing through the second chamber 23 has a structure in which a seventh communication hole 41 communicating with the second chamber 23 is formed.

결론적으로, 상기 소음기로 유입되는 배기가스는 상기 입구파이프(15)를 통해 유입되어, 상기 제3챔버(31)에서 균일하게 빠져 나오고, 일부는 상기 제3배플(7) 및 제4챔버(37)를 경유하여 더욱 크게 돌아 빠져 나옴으로써, 저주파음들 사이의 간섭 및 반사 현상으로 더욱 효과적인 소음 저감이 이루어지는 것이다.In conclusion, the exhaust gas flowing into the muffler flows in through the inlet pipe 15 and exits the third chamber 31 evenly, and part of the third baffle 7 and the fourth chamber 37 is exhausted. By escaping more largely via), more effective noise reduction is achieved due to interference and reflection between low frequency sounds.

물론, 상기 제3챔버(31)로 빠져 나온 배기가스는 상기 중간파이프(19)를 통해 다시 제1챔버(9)로 빠져 나와서 출구파이프(17)를 통해 배출되면서 소음 저감 성능이 더욱 커지게 된다.Of course, the exhaust gas exited to the third chamber 31 exits the first chamber 9 again through the intermediate pipe 19 and is discharged through the outlet pipe 17 to increase the noise reduction performance. .

한편, 도 2에는 본 발명의 다른 실시예를 예시한 것으로서, 상기 제1배플(3)의 제3연통홀(29)과 제2배플(5)의 제4연통홀(33) 및 제3배플(7)의 제6연통홀(39)이 생략된 것인데, 물론, 상기 제3연통홀(29)과 제4연통홀(33) 및 제6연통홀(39)이 도 시된 바와 같이 모두 생략된 구성도 가능하지만, 이들 중 일부만 생략된 구성의 다른 조합도 가능할 것이다.Meanwhile, FIG. 2 illustrates another embodiment of the present invention, wherein the third communication hole 29 of the first baffle 3 and the fourth communication hole 33 and the third baffle of the second baffle 5 are illustrated. The sixth communication hole 39 of (7) is omitted, of course, the third communication hole 29, the fourth communication hole 33 and the sixth communication hole 39 are all omitted as shown Although configurations are possible, other combinations of configurations in which only some of these are omitted will be possible.
