본 발명은 자동차의 머플러를 차체에 고정시켜주는 행거에 관한 것으로 더욱 상세히는 행거의 구조를 개선하여 향상된 머플러의 진동흡수효과를 통해 차량의 진동감쇄성능을 더욱 향상시킬 수 있도록 한 자동차의 머플러 고정용 행거에 관한 것이다.The present invention relates to a hanger for fixing a muffler of an automobile to a vehicle body, and more particularly, to fix a muffler of a vehicle so that the vibration damping performance of the vehicle can be further improved through an improved vibration absorbing effect of the muffler. It's about a hanger.

일반적으로 자동차의 엔진은 다실린더 엔진으로서 각 실린더가 흡입, 압축, 팽창, 배기의 한 사이클을 피스톤의 4행정, 즉 크랭크축 2회전으로 1회의 폭발을 갖으며, 배기행정에 의한 고온고압의 배기가스는 배기장치를 통해 외부로 배출된다.In general, the engine of a vehicle is a multi-cylinder engine, in which each cylinder has one cycle of intake, compression, expansion, and exhaust in one stroke of four strokes of the piston, that is, two revolutions of the crankshaft. The gas is discharged to the outside through the exhaust device.

그리고 상기 배기장치는 각 실린더에서 배기가스를 끌어모으는 배기매니폴드와 배기가스를 차량 뒤쪽의 배출구로 유도하는 배기관 및 배기소음을 저하시키는 머플러(소음기)로 구성된다.The exhaust device includes an exhaust manifold that collects exhaust gas from each cylinder, an exhaust pipe that guides the exhaust gas to the exhaust port at the rear of the vehicle, and a muffler that reduces exhaust noise.

여기서 상기 배기매니폴드는 다실린더 엔진의 각 실린더에서 배출되는 배기가스를 모아 배기관으로 유도하는 부품이며, 배기관은 배기매니폴드에서 나온 배기가스를 차량뒤쪽의 배출구로 유도하는 통로로서 촉매나 소음기를 도중에 넣기 때문에 몇개로 분할되어서 구성된다. Here, the exhaust manifold is a component that collects the exhaust gas discharged from each cylinder of the multicylinder engine and directs it to the exhaust pipe, and the exhaust pipe is a passage that guides the exhaust gas from the exhaust manifold to the exhaust port at the rear of the vehicle. Because it is put in, it is divided into several pieces.

그리고 배기관을 통해 이동되는 배기가스를 대기중에 그대로 내보내게 되면 폭음이 되므로 배기관의 끝단에 머플러를 설치하므로서 상기 머플러를 통하여 그 음을 작게 한다. And when the exhaust gas moved through the exhaust pipe as it is in the air is a sound explosion, the sound is reduced through the muffler by installing a muffler at the end of the exhaust pipe.

한편, 상기 머플러는 탄성체인 행거에 의해 차체에 고정되는데, 이때 행거의 특성이 적절하지 못할 경우 머플러가 차체 또는 지면 등에 부딪치게 되면서 소음이 발생하게 되거나 파손될 수 있으며, 배기관에 공진을 일으켜 내구성을 떨어뜨릴 수도 있는 것이다.On the other hand, the muffler is fixed to the vehicle body by a hanger which is an elastic body, when the characteristics of the hanger is not appropriate, the muffler hits the car body or the ground, etc., noise may be generated or broken, and the exhaust pipe may cause resonance to reduce durability. It could be.

즉, 도 1 은 머플러가 행거에 의해 차체에 고정된 상태를 도시한 것이며, 도 2 는 도 1 의 행거만을 확대하여 도시한 것으로 머플러(20)를 차체(도면중 미도시)의 저면에 설치할 경우 머플러(20)의 진동이 차체로 전달되는 것을 최대한 방지하기 위하여 머플러(20)를 차체에 직접 연결시키지 않고 차체고정용 브라켓(30)과 머플러(20)에 각각 연결구(31)(21)를 형성한 후 상기 연결구(31)(21)의 사이에 행거(10)를 설치하여 차량의 주행에 따른 머플러(20)의 진동이 차체에 직접 전달되는 것을 방지하고 있다.That is, FIG. 1 illustrates a state in which a muffler is fixed to a vehicle body by a hanger, and FIG. 2 illustrates an enlarged view of the hanger of FIG. 1 when the muffler 20 is installed on the bottom of a vehicle body (not shown in the figure). In order to prevent the vibration of the muffler 20 from being transmitted to the vehicle body as much as possible, connectors 31 and 21 are formed in the vehicle body fixing bracket 30 and the muffler 20, respectively, without directly connecting the muffler 20 to the vehicle body. After that, the hanger 10 is installed between the connectors 31 and 21 to prevent the vibration of the muffler 20 from being directly transmitted to the vehicle body.

그러나 상기와 같은 종래의 행거(10)의 경우 하나의 재질을 사용한 일체형으로 구성됨에 따라 행거(10)를 고탄성계수의 재질을 사용하여 제작하게 되면 진동 절연 성능이 저하되고, 장착 또한 용이하지 못하게 되며, 행거(10)를 저탄성계수의 재질을 사용하여 제작할 경우 머플러(20)의 유동이 커지면서 차체 또는 주변부품과의 접촉으로 인하여 소음이 발생하게 되고 머플러(20)가 쉽게 손상되는 문제점이 있었다.However, in the case of the conventional hanger 10 as described above, when the hanger 10 is manufactured using a material having a high modulus of elasticity, the vibration insulation performance is lowered and the mounting is not easy. , When the hanger 10 is manufactured using a material having a low modulus of elasticity, noise is generated due to the contact of the vehicle body or surrounding parts while the flow of the muffler 20 increases, and the muffler 20 is easily damaged.

도면중 미설명 부호(11)은 행거(10)의 내부 중앙에 관통되게 형성되어 행거(10)의 상하부가 탄성을 가지면서 완충작용을 할 수 있도록 한 중공부이고, (12)는 차체고정용 브라켓(30)의 연결구(31)가 끼워지는 설치공이고, (13)은 머플러(20)의 연결구(21)가 끼워지는 설치공이다.In the figure, reference numeral 11 is a hollow part formed to penetrate through the inner center of the hanger 10 so that the upper and lower parts of the hanger 10 may have elasticity and have a buffering action, and 12 is for fixing the vehicle body. The connection hole 31 of the bracket 30 is fitted, and the installation hole 13 is an installation hole to which the connector 21 of the muffler 20 is fitted.

따라서 본 발명의 목적은 상기와 같은 문제점을 해결하기 위한 것으로서, 차체에 머플러를 고정시켜주는 행거를 구성함에 있어서 형상의 변경을 통해 머플러의 진동은 효과적으로 감쇄시키고, 차체 또는 주변 부품과의 간섭을 방지하여 차량의 진동감쇄성능을 더욱 향상시킬 수 있도록 한 자동차의 머플러 고정용 행거를 제공하는데 있다.Accordingly, an object of the present invention is to solve the above problems, in the configuration of the hanger for fixing the muffler to the vehicle body by effectively changing the shape of the vibration of the muffler effectively prevents interference with the vehicle body or peripheral parts In order to further improve the vibration damping performance of the vehicle is to provide a hanger for fixing the muffler of the vehicle.

이와 같은 본 발명의 목적은 머플러의 진동이 차체로 전달되지 않도록 상하부에는 차체고정용 브라켓의 연결구와 머플러의 연결구가 결합되는 설치공이 형성되고, 중앙에는 관통된 중공부가 구비된 행거를 구성함에 있어서, 행거몸체의 중공부 내부 저면에 제1돌출부를 돌출되게 연장시켜 형성하고, 상기 제1돌출부의 상면에는 제1돌출부보다 직경이 작은 제2돌출부를 돌출되게 연장시켜 구성하므로서 달성되는 것이다.The object of the present invention as described above is formed in the upper and lower mounting holes for coupling the connector of the vehicle body fixing bracket and the coupling of the muffler so that the vibration of the muffler is not transmitted to the vehicle body, and in the center of the hanger is provided with a hollow portion, The first protrusion is formed to protrude from the inner bottom of the hollow part of the hanger body, and the second protrusion is smaller than the first protrusion to protrude from the upper surface of the first protrusion.

이러한 본 발명은 행거몸체에 중공부만이 형성될 경우 머플러의 과도한 유동에 따른 진동에 충분히 대응하지 못하지만 본 발명에서는 머플러가 과도하게 유동되더라도 중공부에 위치한 제1,2돌출부가 중공부의 내부 상면과 접촉되면서 머플러의 유동에 따른 진동을 순차적으로 완충시켜 진동감쇄성능을 더욱 향상시킬 수 있으므로 상기 목적을 달성할 수 있는 것이다.The present invention does not sufficiently cope with vibration caused by excessive flow of the muffler when only the hollow part is formed in the hanger body. However, in the present invention, the first and second protrusions positioned in the hollow part have an inner upper surface of the hollow part even though the muffler is excessively flowed. By vibrating the vibrations in accordance with the flow of the muffler while being in contact with each other to further improve the vibration damping performance will achieve the above object.

이하, 본 발명의 특징을 효과적으로 달성할 수 있는 바람직한 실시 예로서 그 기술구성 및 작용효과를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the technical configuration and operational effects as a preferred embodiment that can effectively achieve the features of the present invention will be described.

즉, 도 3 은 본 발명에 따른 행거를 예시한 사시도이고, 도 4 는 본 발명에 따른 행거의 정면도이며, 도 5 는 본 발명에 따른 행거의 측면도이다.3 is a perspective view illustrating a hanger according to the present invention, FIG. 4 is a front view of the hanger according to the present invention, and FIG. 5 is a side view of the hanger according to the present invention.

이에 예시한 바와 같이 본 발명은 머플러(도면중 미도시)의 진동이 차체로 전달되지 않도록 상하부에는 차체고정용 브라켓(도면중 미도시)의 연결구(310)와 머플러의 연결구(210)가 결합될 수 있는 설치공(120)(130)이 형성되고, 중앙에는 관통된 중공부(110)가 구비된 행거를 구성함에 있어서, As illustrated in the present invention, the upper and lower portions of the connector 310 of the vehicle body fixing bracket (not shown in the drawing) and the connector 210 of the muffler are coupled to the upper and lower parts so that the vibration of the muffler (not shown) is transmitted to the vehicle body. In the installation hole 120, 130 can be formed, and in forming a hanger provided with a hollow portion 110 through the center,

행거몸체(100)의 중공부(110) 내부 저면(110a)에 제1돌출부(111)를 돌출되게 연장시켜 형성하고, 상기 제1돌출부(111)의 상면에는 제1돌출부(111)보다 직경이 작은 제2돌출부(112)를 돌출되게 연장시켜 형성하며, The first protrusion 111 is formed to protrude from the bottom surface 110a of the hollow body 110 of the hanger body 100, and the diameter of the first protrusion 111 is greater than that of the first protrusion 111. Is formed by extending the small second protrusion 112 to protrude,

행거몸체(100)의 중공부(110) 양측에 위치한 행거몸체(100)의 양측부(140) 두께는 다른부위에 비하여 비하여 얇게 구성하고, 행거몸체(100)의 상면과 저면에는 서로 다른 형상을 가지는 위치확인용 표시부(151)(152)를 형성한 것이 특징인 것이다.The thickness of both sides 140 of the hanger body 100 located on both sides of the hollow part 110 of the hanger body 100 is thinner than other parts, and the upper and lower surfaces of the hanger body 100 have different shapes. The branch is characterized in that the position display unit 151, 152 is formed.

도면중 미설명 부호(113)은 제1돌출부(111)와 제2돌출부(112)의 사이 및 제2돌출부(112)의 상면에 형성된 안착부이다.In the drawing, reference numeral 113 is a seating portion formed between the first protrusion 111 and the second protrusion 112 and on the upper surface of the second protrusion 112.

이러한 본 발명은 차체에 머플러를 고정시키되 완충작용을 하면서 머플러가 차체 또는 타 부품과 간섭되지 않도록 하기 위하여 차체와 머플러의 사이에 설치되는 행거를 구성함에 있어서, 행거몸체(100)의 중공부(110)에 2단으로 이루어지는 제1,2돌출부(111)(112)를 구비하고 행거몸체(100)의 양측부(140) 두께를 타부위에 비해 얇게 구성하므로서 행거몸체(100)의 완충능력을 더욱 향상시킴에 따라 머플러의 진동이 효과적으로 제어되면서 차량의 진동감쇄성능이 더욱 배가될 수 있도록 한 것이다.In the present invention, while fixing the muffler to the vehicle body, while configuring a hanger installed between the vehicle body and the muffler in order to prevent the muffler from interfering with the vehicle body or other components, the hollow portion 110 of the hanger body 100 2) the first and second protrusions 111 and 112 having two steps, and the thickness of both sides 140 of the hanger body 100 is thinner than the other parts, thereby further buffering the hanger body 100. As the vibration of the muffler is effectively controlled, the vibration damping performance of the vehicle can be further increased.

즉, 도 3 은 본 발명에 따른 행거몸체를 예시한 것으로서, 그 구조를 상세히 살펴보면 우선, 행거몸체(100)의 상측과 하측에 차체고정용 브라켓에 형성된 연결구(310)와 머플러에 형성된 연결구(210)가 끼워져 결합될 수 있도록 설치공(120)(130)이 형성되고, 행거몸체(100)의 중앙부위에 관통된 형태의 중공부(110)가 형성되어 상기 중공부(110)에 의해 행거몸체(100)가 상하부간의 탄성을 가지면서 완충작용이 가능하도록 한 구성은 종래의 구성과 동일하다고 할 수 있다.That is, Figure 3 illustrates a hanger body according to the present invention, looking at the structure in detail, first, the connector 310 formed in the bracket for fixing the vehicle body on the upper side and the lower side of the hanger body 100 and the connector 210 formed in the muffler The mounting holes 120 and 130 are formed to be coupled to each other, and the hollow part 110 having a penetrated shape is formed in the center of the hanger body 100 so that the hanger body is formed by the hollow part 110. It can be said that the configuration that the buffer 100 is capable of buffering action while having elasticity between the upper and lower portions is the same as the conventional configuration.

여기서 본 발명의 특징은 행거몸체(100)에 형성되는 중공부(110)만으로는 행거몸체(100)의 완충작용이 효과적으로 이루어지기 어려운 문제점을 해결하고자 하는 것으로서, 상기 중공부(110)의 크기를 필요이상 작게 형성하거나, 필요이상 크게 형성하게 되면 완충작용이 제대로 이루어지지 못하여 진동감소효과가 떨어지게 되거나, 타부품과의 간섭으로 인하여 소음 또는 머플러의 손상을 가져오게 되는 것이다.The feature of the present invention is to solve the problem that it is difficult to effectively buffer the hanger body 100 by the hollow portion 110 formed on the hanger body 100, the size of the hollow portion 110 is required If it is formed smaller or larger than necessary, the shock absorbing effect is not properly made, the vibration reduction effect is reduced, or the noise or damage to the muffler due to interference with other parts.

따라서 본 발명에서는 중공부(110)의 내부 저면(110a)에 상측으로 돌출되어 연장되는 형태의 제1돌출부(111)가 형성되고, 상기 제1돌출부(111)의 상면에는 역시 상측으로 돌출되어 연장되는 제2돌출부(112)가 적층되는 상태로 형성되며, 이때 상기 제1돌출부(111)의 직경에 비하여 제2돌출부(112)의 직경은 작게 형성된 것이고, 제2돌출부(112)의 상면과 중공부(110)의 내부 상면(110b)과는 일정한 간격이 유지되도록 한 것이다.Therefore, in the present invention, a first protrusion 111 having a shape protruding upward from the inner bottom surface 110a of the hollow part 110 is formed, and protrudes upward from the top surface of the first protrusion 111. The second protrusion 112 is formed in a stacked state, wherein the diameter of the second protrusion 112 is smaller than that of the first protrusion 111, and the upper surface and the hollow of the second protrusion 112 are formed. It is to maintain a constant distance from the inner upper surface (110b) of the portion (110).

여기서 상기 제1돌출부(111)와 제2돌출부(112)를 직경이 서로 다른 형태로 구성하여 적층되게 형성한 것은 동일한 직경을 가지는 하나의 돌출부에 비하여 완충효과가 더욱 크기 때문이다.In this case, the first protrusion 111 and the second protrusion 112 are formed to have different diameters and are stacked so that the buffering effect is greater than that of one protrusion having the same diameter.

즉, 행거몸체(100)가 머플러의 진동에 의해 유동되면 행거몸체(100)의 중공부(110) 상/저면(110b)(110a)의 간격이 변형되면서 그 진동을 감쇄시키게 되는데, 이때 상기 중공부(110) 상/저면(110b)(110a) 간격의 변형이 큰 경우에는 제2돌출부(112)가 중공부(110)의 내부 상면(110b)과 접촉되면서 제2돌출부(112)의 변형에 의해 1차적으로 진동이 감소될 수 있는 것이며, 상기 제2돌출부(112)의 변형을 초과하는 진동은 연속된 제1돌출부(111)의 변형에 의해 2차적으로 진동이 감소됨에 따라 상기 제1돌출부(111)와 제2돌출부(112)에 의해 행거몸체(100)의 완충성능은 더욱 향상될 수 있는 것이다.That is, when the hanger body 100 flows due to the vibration of the muffler, the gap between the upper and lower surfaces 110b and 110a of the hollow part 110 of the hanger body 100 is deformed to attenuate the vibration. When the deformation of the upper and lower surfaces 110b and 110a of the upper part 110 is large, the second protruding portion 112 contacts the inner upper surface 110b of the hollow part 110 and thus the second protruding portion 112 deforms. The vibration may be primarily reduced by the vibration, and the vibration exceeding the deformation of the second projection 112 may be reduced by the vibration of the first projection 111 continuously. By the 111 and the second protrusion 112, the buffering performance of the hanger body 100 can be further improved.

그리고 상기와 같이 제1돌출부(111)와 제2돌출부(112)를 형성함에 있어서, 제1돌출부(111)와 제2돌출부(112)의 연결부위 및 제2돌출부(112)의 상면에 각각 제1돌출부(111)와 제2돌출부(112)의 직경에 보다 큰 직경을 가지는 안착부(113)를 형성하게 되면 제1돌출부(111)와 제2돌출부(112)의 접지면적 및 제2돌출부(112)와 중공부(110) 상면(110b)과의 접지면적이 증가하게 되면서 진동의 감소효과를 더욱 크게 할 수 있는 것이다.In forming the first protrusion 111 and the second protrusion 112 as described above, the first protrusion 111 and the second protrusion 112 are connected to the first protrusion 111 and the second protrusion 112, respectively, on the upper surface of the second protrusion 112. When the seating portion 113 having a larger diameter is formed in the diameter of the first protrusion 111 and the second protrusion 112, the ground area and the second protrusion of the first protrusion 111 and the second protrusion 112 are formed. As the ground area between 112 and the hollow part 110, the upper surface 110b is increased, the vibration reduction effect can be further increased.

Through the display units 151 and 152, the installation work can be more accurately and effectively.

여기서 상기 위치확인용 표시부(151)(152)는 여러가지의 형태나 색상 또는 크기 등으로 구분시켜 형성할 수 있으며, 본 발명에서는 행거몸체(100)의 상면에 위치한 위치확인용 표시부(151)를 저면에 위치한 위치확인용 표시부(152)보다 크게 형성하여 구분되도록 한 것이다.Wherein the positioning display unit 151, 152 may be formed in various forms, colors or sizes, and the like, in the present invention, the positioning display unit 151 located on the upper surface of the hanger body 100 It is to be formed by forming larger than the positioning display unit 152 located in.

이상과 같이 본 발명의 바람직한 실시 예를 설명하였으나 본 발명은 다양한 변화와 변경 및 균등물을 사용할 수가 있으며, 상기 실시 예를 적절히 변형하여 동일하게 응용할 수 있음이 명확하다. 따라서 상기 기재 내용은 하기 특허청구범위의 한계에 의해 정해지는 본 발명의 범위를 한정하는 것은 아니다.As described above, the preferred embodiment of the present invention has been described, but the present invention may use various changes, modifications, and equivalents, and it is clear that the above embodiments may be appropriately modified and applied in the same manner. Therefore, the above description does not limit the scope of the invention defined by the limitations of the following claims.

이상에서 상술한 바와 같이 본 발명은 행거몸체의 중공부에 2단으로 이루어진 돌출부를 형성하여 머플러가 과도하게 유동될 경우 상기 돌출부가 중공부의 내부 상면과 접촉되면서 머플러의 유동에 따른 진동을 순차적으로 완충시켜 진동감쇄성능을 더욱 향상시킬 수 있는 것이며, 아울러 행거몸체의 양측부가 얇게 구성됨에 따라 행거몸체의 신축성을 더욱 향상될 수 있고, 행거몸체의 상면과 저면에 각각 위치확인용 표시부가 형성됨에 따라 행거의 설치작업성을 더욱 향상시킬 수 있는 것이다.As described above, the present invention forms a protrusion having two stages in the hollow portion of the hanger body when the muffler is excessively flown while the protrusion is in contact with the inner upper surface of the hollow portion to sequentially damp vibrations caused by the flow of the muffler. The vibration damping performance can be further improved, and both sides of the hanger body can be made thinner, and thus the elasticity of the hanger body can be further improved. It is possible to further improve the installation workability.
