본 발명은 자동차의 배기장치 행거러버에 관한 것으로서, 구체적으로 소정의 지지력을 갖는 지지프레임이 행거러버의 내주면을 따라 밀착되게 삽입되어 설치되어 행거러버의 지지력 및 방진기능을 향상시키는 자동차의 배기장치 행거러버에 관한 것이다.The present invention relates to an exhaust system hanger rubber of a vehicle, and more specifically, a support frame having a predetermined support force is inserted and installed in close contact with an inner circumferential surface of a hanger rubber to improve the support force and the dustproof function of the hanger rubber. It's about rubber.

일반적으로 자동차의 배기장치는 엔진의 연소실에서 발생된 배기가스를 외부로 배출하기 위하여 사용되는 장치로서, 엔진과 배기파이프 사이에 연결되어 엔진의 연소실에서 발생된 배기가스를 모아서 배기파이프로 방출하는 배기 매니폴드(Exhaust Manifold)와, 매니폴드에 연결되는 배기파이프 및, 배기파이프에 연결되어 배기소음을 감쇠하는 소음기로 구성된다.In general, the exhaust system of a vehicle is a device used to exhaust the exhaust gas generated in the combustion chamber of the engine to the outside, and is connected between the engine and the exhaust pipe to collect the exhaust gas generated in the combustion chamber of the engine and discharge it to the exhaust pipe An exhaust manifold, an exhaust pipe connected to the manifold, and a silencer connected to the exhaust pipe to attenuate exhaust noise.

행거러버(Hanger Rubber)란 통상 탄성의 성질을 갖는 고무재질로 제작되며, 고온/고압의 배기가스가 배기장치를 통과하는 과정에서 발생되는 진동이 차체까지 전달되는 것을 저감하는 방진기능을 함께 수행하는 배기장치 고정구이다.Hanger rubber (Hanger Rubber) is usually made of a rubber material having an elastic property, and performs a dust-proof function to reduce the transmission of vibration generated in the process of passing the exhaust gas of high temperature / high pressure to the vehicle body Exhaust fixture.

즉, 배기장치는 도 1에 도시된 바와 같이 행거러버(Hanger Rubber)에 의해 차량의 저면부에 장착된다. 행거러버(10)는 배기장치(20)를 차량(30) 저면에 고정시키게 되며, 탄성을 갖는 몸통부(70)와, 몸통부에 형성된 차체 고정홀(40) 및 배기장치 고정홀(50)과, 방진기능을 위한 완충홀(60)로 구성된다.That is, the exhaust device is mounted to the bottom of the vehicle by a hanger rubber (Hanger Rubber) as shown in FIG. The hanger rubber 10 fixes the exhaust device 20 to the bottom surface of the vehicle 30, and has a body portion 70 having elasticity, a vehicle body fixing hole 40 formed in the body portion, and an exhaust device fixing hole 50. And, it is composed of a buffer hole 60 for the dust-proof function.

그러나, 기존의 행거러버는 배기장치에서 발생되는 열과 배기장치 자체 무게에 의한 하중을 견디지 못하여 파손되는 경우가 빈번하다는 문제점이 있다. 특히, 배기규제 법규의 강화에 따라 매연여과장치(DPF)가 배기장치에 추가적으로 설치됨에 따라 배기장치의 무게 및 발열량이 증가되는 것이 최근의 추세이기 때문에 종래 의 행거러버는 내구성이 떨어지고 방진기능이 약화되는 문제점이 있다.However, there is a problem that the existing hanger rubber is often damaged due to the heat generated in the exhaust device and the load due to the weight of the exhaust device itself. In particular, in accordance with the recent tightening of exhaust regulations, the weight and calorific value of the exhaust system is increased as the exhaust filter (DPF) is additionally installed in the exhaust system. Therefore, the hanger rubber is less durable and the dustproof function is weakened. There is a problem.

본 발명은 상기와 같은 문제점을 감안하여 안출된 것으로서, 기존의 탄성 재질의 몸체를 그대로 사용하면서도 지지력 및 방진기능이 향상된 자동차의 배기장치 행거러버를 제공하는데 그 목적이 있다.The present invention has been made in view of the above problems, it is an object of the present invention to provide an exhaust system hanger rubber of the vehicle with improved support and anti-vibration function while using the body of the existing elastic material as it is.

상기 목적을 달성하기 위한 본 발명에 따른 자동차의 배기장치 행거러버는, 탄성을 갖는 몸통부와, 상기 몸통부 일측에 형성된 차체 고정홀과, 상기 몸통부 타측에 형성된 배기장치 고정홀, 및 상기 몸통부에 형성되어 충격을 흡수하는 완충홀로 구성된 자동차의 배기장치 행거러버에 있어서, 상기 행거러버의 내주면을 따라 밀착되는 지지프레임이 상기 행거러버의 내부로 삽입되어 설치되는 것을 특징으로 한다.Exhaust hanger rubber of the vehicle according to the present invention for achieving the above object, the body portion having elasticity, the vehicle body fixing hole formed on one side of the body portion, the exhaust device fixing hole formed on the other side of the body portion, and the body In the exhaust system hanger rubber of a vehicle formed of a buffer hole for absorbing the shock is formed, the support frame which is in close contact along the inner circumferential surface of the hanger rubber is characterized in that is installed inserted into the hanger rubber.

또한, 상기 지지프레임에는 상기 몸통부 내부로 연장되는 날개편이 형성되는 것이 바람직하다.In addition, the support frame is preferably formed with a wing piece extending into the body portion.

또한, 상기 지지프레임은 알루미늄 재질로 형성되는 것이 바람직하다.In addition, the support frame is preferably formed of an aluminum material.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 따른 자동차의 배기장치 행거러버를 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail an exhaust system hanger rubber of a vehicle according to an embodiment of the present invention.

도 2는 본 발명의 실시예에 따른 자동차의 배기장치 행거러버의 일부가 절개 된 사시도이며, 도 3은 도 2에 따른 자동차의 배기장치 행거러버의 단면도이다.2 is a perspective view of a portion of the exhaust system hanger rubber of the vehicle according to the embodiment of the present invention, Figure 3 is a cross-sectional view of the exhaust system hanger rubber of the vehicle according to FIG.

도시된 바와 같이, 본 발명에 따른 자동차의 배기장치 행거러버는 몸통부(110), 고정홀(120)(130) 및, 완충홀(140)로 구성된 행거러버(100)에 있어서, 지지프레임(200)이 상기 행거러버(100)의 내부에 삽입되어 설치된다.As shown, the exhaust system hanger rubber of the vehicle according to the present invention in the hanger rubber 100 consisting of a body portion 110, a fixing hole 120, 130, and a buffer hole 140, the support frame ( 200 is inserted into the hanger rubber 100 is installed.

몸통부(110)는 탄성을 가진 방진고무로 형성되어 배기장치가 진동을 하는 경우, 진동에 의한 운동에너지를 흡수하여 운전자에게 진동이 전해지는 것을 방지하게 된다. The trunk portion 110 is formed of an elastic dustproof rubber to prevent the vibration from being transmitted to the driver by absorbing the kinetic energy caused by the vibration when the exhaust device vibrates.

차체 고정홀(120)에는 차량의 저면에 형성된 차량 브라켓이 삽입되고, 배기장치 고정홀(130)에는 배기장치 브라켓이 삽입되어 차량 저면부에 배기장치를 연결시킨다. A vehicle bracket formed on the bottom of the vehicle is inserted into the vehicle body fixing hole 120, and an exhaust device bracket is inserted into the exhaust device fixing hole 130 to connect the exhaust device to the bottom surface of the vehicle.

완충홀(140)은 충격을 흡수하기 위한 것으로 몸통부(110)를 관통하여 적어도 하나 이상 형성된다.At least one buffer hole 140 is formed to penetrate the body part 110 to absorb the shock.

지지프레임(200)은 상기 행거러버(100)의 내부로 삽입되어 설치되는데, 이러한 지지프레임(200)은 행거러버(100)의 내구성 및 방진기능을 강화시키기 위한 것이다. 즉, 지지프레임(200)이 행거러버(100)의 내주면에 밀착고정되어 상기 행거러버(100)가 배기장치의 하중 및 발열로 인해 찢어지거나 파손되는 것을 방지하는 역할을 한다. 여기서 내주면이란 상기 행거러버(100)의 최외각 표면의 안쪽 둘레를 말하는 것으로서, 상기 지지프레임(200)은 최외각 표면의 안쪽 둘레에 밀착되어 설치된다.The support frame 200 is inserted into the hanger rubber 100 and installed therein. The support frame 200 is for reinforcing the durability and dustproof function of the hanger rubber 100. That is, the support frame 200 is fixed to the inner circumferential surface of the hanger rubber 100 to prevent the hanger rubber 100 from being torn or broken due to the load and heat of the exhaust device. Herein, the inner circumferential surface refers to the inner circumference of the outermost surface of the hanger rubber 100, and the support frame 200 is installed in close contact with the inner circumference of the outermost surface.

다시 말해, 행거러버(100)의 몸통부(110)는 탄성을 갖는 방진고무로 형성되 기 때문에 과도한 하중이 걸리거나 고온의 환경에 놓이게 되면 파손이 될 우려가 있는데, 상기 지지프레임(200)이 행거러버(100)의 내주면에 삽입됨으로써, 홀(120)(130)(140) 주위의 몸통부(110)가 단락되더라도 배기장치가 이탈되는 것을 방지하게 되는 것이다.In other words, since the trunk portion 110 of the hanger rubber 100 is formed of an anti-vibration rubber having elasticity, there is a risk of being damaged when excessive load is applied or placed in a high temperature environment, and the support frame 200 is hanger By being inserted into the inner circumferential surface of the rubber 100, even if the body portion 110 around the holes 120, 130, 140 is short-circuited is to prevent the exhaust device from being separated.

따라서, 상기 지지프레임(200)에는 소정의 날개편(210)이 행거러버(100)의 내부로 연장형성되는 것이 더 바람직하다. 또한, 상기 지지프레임(200)은 알루미늄과 같이 내열성 및 내구성이 좋은 금속재질로 형성되는 것이 유리하다. Therefore, it is more preferable that a predetermined wing piece 210 extends into the hanger rubber 100 in the support frame 200. In addition, the support frame 200 is advantageously formed of a metal material having good heat resistance and durability, such as aluminum.

결국, 차체 브라켓이 삽입되는 차체 고정홀(120)과 배기장치 브라켓이 삽입되는 배기장치 고정홀(130) 부위는 방진고무로 이루어져 진동을 흡수하고 전체 외곽부위는 알루미늄 재질의 지지프레임(200)이 삽입되어 몸통부(110)가 찢어지거나 파손되더라도 차체 브라켓 또는 배기장치 브라켓이 행거러버(100)로부터 이탈되는 것이 방지되는 것이다.As a result, the body fixing hole 120 into which the body bracket is inserted and the exhaust device fixing hole 130 into which the exhaust device bracket are inserted are made of anti-vibration rubber to absorb vibration and the entire outer portion of the support frame 200 is made of aluminum. Even if the torso 110 is torn or broken, the body bracket or the exhaust device bracket is prevented from being separated from the hanger rubber 100.

이상에서 본 발명의 바람직한 실시예에 대하여 설명하였으나 본 발명은 상술한 특정의 실시예에 한정되지 아니한다. 즉, 본 발명이 속하는 기술분야에서 통상의 지식을 가지는 자라면 첨부된 특허청구범위의 사상 및 범주를 일탈함이 없이 본 발명에 대한 다수의 변경 및 수정이 가능하며, 그러한 모든 적절한 변경 및 수정의 균등물들도 본 발명의 범위에 속하는 것으로 간주되어야 할 것이다.Although preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described specific embodiments.
