본 발명은 차량의 배기시스템용 행거에 관한 것이며, 상세하게는 차량용 배기시스템의 배기파이프 및 머플러 등을 차체에 진동을 절연시켜 설치하는 고무제 행거에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanger for an exhaust system of a vehicle, and more particularly to a rubber hanger for installing exhaust pipes, mufflers, etc. of a vehicle exhaust system insulated from vibration.

주지하는 바와 같이 차량 중 내연기관을 사용하는 차량은 내연기관의 연소실에서 연소된 고온ㆍ고압의 연소가스가 대기중으로 방출될 때 배기시스템이 진동을 하게 되며, 상기 배기시스템의 진동을 절연하기 위하여 배기시스템을 차체의 저면 에 설치할 때 배기파이프 및 머플러 등과 차체 사이에 고무제 행거를 설치하고 있다.As is well known, in a vehicle using an internal combustion engine, the exhaust system vibrates when the high-temperature and high-pressure combustion gas combusted in the combustion chamber of the internal combustion engine is released into the atmosphere, and the exhaust system insulates the vibration of the exhaust system. When the system is installed on the bottom of the body, a rubber hanger is installed between the exhaust pipe and the muffler and the body.

상기한 행거는 도 3 및 도 4에 도시한 바와 같이, 고무제 행거본체(20)를 대략 타원형으로 형성함과 아울러 그 대향부에 행거 써포트 지지공(21a)(21b)을 형성하고, 상기 행거 써포트 지지공(21a)(21b) 사이에 임의단면의 진동흡수공동(22)을 형성한 것이다.As shown in Figs. 3 and 4, the hanger forms a rubber-shaped hanger main body 20 in a substantially elliptical shape, and forms hanger support supporting holes 21a and 21b at opposite sides thereof. The vibration absorbing cavity 22 of arbitrary cross section is formed between the support support holes 21a and 21b.

상기한 행거는 배기시스템을 차체에 간편하고 신속하게 설치하고, 또한 진동절연을 양호하게 하는 것이 바람직하다.It is preferable that the above-mentioned hanger installs the exhaust system in the vehicle body easily and quickly, and improves vibration insulation.

그러나 상기한 고무제 행거는 차체와 배기시스템에 고정한 행거 써포터에 행거 써포트 지지공(21a)(21b)을 삽입하여 설치할 때 그 고정을 견고하게 하기 위하여 행거본체(20)의 강성을 크게 하여 고탄성 계수의 재질을 선정하면 고정은 견고하게 되지만 진동절연 성능이 저하되고, 또한 행거 써포터에 행거 써포트 지지공(21a)(21b)을 삽입하거나 인출할 때 작업공수가 많이 소요되는 것이다.However, the above-mentioned rubber hanger has a high modulus of elasticity by increasing the rigidity of the hanger main body 20 so as to secure the fixing when the hanger support supporting holes 21a and 21b are inserted into the hanger supporter fixed to the vehicle body and the exhaust system. When the material is selected, the fixing becomes firm, but the vibration insulation performance is deteriorated, and a lot of work is required when inserting or drawing the hanger support supporting holes 21a and 21b into the hanger supporter.

한편 행거본체(20)의 재질을 저탄성 계수의 것으로 선정하면 행거본체(20)를 설치하거나 분리할 때 신속하여 작업공수를 절감할 수 있지만 행거본체(20)의 유동이 커짐으로써 주변 부품들과의 간극산포가 커지게 되어 간섭이 발생하는 문제점이 발생하는 것이다.On the other hand, if the material of the hanger main body 20 is selected to have a low modulus of elasticity, it is possible to reduce the work maneuver quickly when installing or removing the hanger main body 20, but the flow of the hanger main body 20 increases and the surrounding parts The gap dispersion of the becomes large, the interference occurs.

본 발명은 상기한 문제점을 시정하여, 설치가 신속하고, 진동감쇠가 양호한 차량의 배기시스템용 행거를 제공하는 것을 목적으로 한다.SUMMARY OF THE INVENTION An object of the present invention is to provide a hanger for an exhaust system of a vehicle, in which the above problems are corrected and the installation is quick and the vibration attenuation is good.

상기한 목적을 달성하기 위하여, 본 발명은 고무제 행거본체의 대향부에 행거 써포트 지지공을 형성함과 아울러 상기 행거 써포트 지지공 사이에 지지벽을 사이에 두고 진동흡수공동 AㆍB를 구획 형성하며, 상기 지지벽에 수개의 구멍을 형성한 강판제 보강판을 매설하여서, 구멍을 통하여 강판제 보강판 양측의 지지벽을 연결부로 일체화하여서 된 것이다.In order to achieve the above object, the present invention provides a hanger support support hole in an opposing portion of the rubber hanger body, and partitions the vibration absorbing cavity A and B with a support wall between the hanger support support holes. And embedding the reinforcing plate made of steel sheet having several holes in the supporting wall, and integrating the supporting walls on both sides of the reinforcing plate made of steel plate through the holes.

본 발명은 도 1 및 도 2에 도시한 바와 같이, 고무제 행거본체(10)의 대향부에 행거 써포트 지지공(11a)(11b)을 형성함과 아울러 상기 행거 써포트 지지공 (11a)(11b) 사이에 지지벽(12)을 사이에 두고 진동흡수공동 AㆍB(13a)(13b)를 구획 형성하며, 상기 지지벽(12)에 수개의 구멍(15)을 형성한 강판제 보강판(14)을 매설하여서, 구멍(15)을 통하여 강판제 보강판(14) 양측의 지지벽(12)을 연결부(16)로 일체화하여서 된 것이다.As shown in Figs. 1 and 2, the hanger support supporting holes 11a and 11b are formed on the opposite portions of the rubber hanger body 10, and the hanger support supporting holes 11a and 11b are formed. The steel plate reinforcement plate which partitions the vibration absorbing cavities A and B 13a and 13b with the support wall 12 between them, and forms several holes 15 in the support wall 12 ( 14 is embedded by integrating the support walls 12 on both sides of the steel reinforcement plate 14 through the holes 15 into the connecting portions 16.

상기 행거본체(10)는 4각형으로 형성하여 진동전달경로를 길게 함으로써 진동감쇠 효과를 증진한 것이다.The hanger main body 10 is formed in a quadrangular shape to enhance the vibration damping effect by lengthening the vibration transmission path.

상기 강판제 보강판(14)은 그 양측에 절곡부(24a)(24b)를 상호 반대방향으로 형성하여 그 면적을 증대하여 행거본체(10)의 유동시에 강판제 보강판(14)의 양측면이 행거본체(10)에 가하는 힘을 분산함으로써 응력집중을 방지하여 수명을 연장한 것이다.The steel plate reinforcing plate 14 has bent portions 24a and 24b formed on both sides thereof in opposite directions to increase the area thereof so that both sides of the steel plate reinforcing plate 14 are changed during the flow of the hanger body 10. By dispersing the force applied to the hanger main body 10, stress concentration is prevented and the life is extended.

그리고 상기 금속제 보강판(14)의 절곡부(24a)(24b)의 양측면은 행거본체 (10)에 매설하고, 전후면(25a)(25b)은 행거본체(10)를 관통하여 돌출시켜서 행거본 체(10)의 회전을 방지할 수 있도록 한 것이다.Both sides of the bent portions 24a and 24b of the metal reinforcing plate 14 are embedded in the hanger body 10, and the front and rear surfaces 25a and 25b protrude through the hanger body 10 to protrude. It is to prevent the rotation of the sieve (10).

이상과 같은 본 발명은 행거 써포트 지지공(11b)을 배기시스템에 고정한 행거 써포트에 삽입 설치하고, 행거 써포트 지지공(11a)을 차체에 설치한 행거 써포터에 삽입 설치하여 행거본체(10)를 설치하고 차량을 주행할 경우, 배기시스템의 진동에 의하여 그 진동이 행거 써포트 지지공(11b)에 전달되면 행거 써포트 지지공(11b)의 상부에 진동흡수공동 A(13a)가 형성되어 있음으로 그 진동은 대각선 방향으로 전달되며, 상기와 같이 대각선 방향으로 전달되는 진동은 지지벽(12)에 매설된 강판제 보강판(14)에 의하여 1차 차단되어 스톱퍼 기능을 한 후 강판제 보강판(14)에 형성한 구멍(15)을 통하여 일체화된 연결부(16)를 통하여 상부로 전달됨으로써 종래의 것에 비하여 진동의 전달경로가 길어지기 때문에 진동절연이 양호하여 진동감쇠가 양호하게 되는 것이다.According to the present invention as described above, the hanger support support hole 11b is inserted into the hanger support fixed to the exhaust system, and the hanger support support 11a is inserted into the hanger supporter provided in the vehicle body to install the hanger main body 10.

Is transmitted in a diagonal direction, and the vibration transmitted in the diagonal direction as described above is primarily blocked by the steel reinforcement plate 14 embedded in the support wall 12 to serve as a stopper, and then the steel reinforcement plate 14. Since the transmission path of vibration is longer than that of the related art by being transmitted upward through the connecting portion 16 integrated through the hole 15 formed in the hole, vibration isolation is good and vibration damping is good.

그리고 행거본체(10)가 회전진동을 받아 행거본체(10)의 유동이 발생할 때 금속제 보강판(14)이 이를 저지함으로써 내구성을 증진하는 것이다.In addition, when the hanger body 10 receives rotational vibration and the flow of the hanger body 10 occurs, the metal reinforcing plate 14 prevents it, thereby improving durability.

이상과 같이 본 발명은 행거본체의 재질을 적정의 탄성계수를 가진 것으로 선정할 수 있음으로 설치가 신속하고, 행거본체에 지지벽을 형성하여 금속제 보강판을 매설함과 아울러 금속제 보강판에 구멍을 형성하여 지지벽을 연결부로 일체화함으로써 하부의 진동이 상부로 전달될 때 1차로 금속제 보강판에 의하여 차단한 후 연결부를 통하여 상부로 전달되게 하여 진동전달경로를 길게 함으로써 진동감쇠가 양호하게 되는 것이다.As described above, according to the present invention, the material of the hanger main body can be selected to have an appropriate modulus of elasticity, so that the installation is quick, and the support wall is formed on the hanger main body to embed the metal reinforcement plate, and the hole in the metal reinforcement plate. When the vibration of the lower portion is formed by integrating the supporting wall to the upper portion, the vibration is attenuated by lengthening the vibration transmission path by blocking the first by the metal reinforcement plate and then transmitting the upper portion through the connecting portion.

또한 행거본체에 금속제 보강판을 매설함으로써 행거본체가 회전진동을 받을 경우에도 유동을 저지함으로써 처짐 및 회전을 억제하여 수명을 대폭 연장할 수 있는 것이다.Also, by embedding a metal reinforcing plate in the hanger body, even when the hanger body is subjected to rotational vibration, the hanger body can be prevented from sagging and rotation, thereby greatly extending the life.
