우선 도 3 및 도 4에 도시된 바와같이, 본 발명의 자동차의 머플러 행거장치는 크게 고무재로 이루어진 진동흡수재(110)와, 상기 진동흡수재(110)의관통홀(112)내에 삽입되는 파이프(120)와, 상기 파이프(120)의 끝단에 결합되는 볼트(140)로 구성된다.First, as illustrated in FIGS. 3 and 4, the muffler hanger device of the vehicle of the present invention includes a vibration absorber 110 made of a rubber material and a pipe inserted into the through hole 112 of the vibration absorber 110. 120 and a bolt 140 coupled to the end of the pipe 120.

전술한 진동흡수재(110)는 차체프레임(3)에 고정되어 있으며 그 내부에 관통홀(112)이 형성되어 있다.The vibration absorbing member 110 is fixed to the vehicle body frame 3 and a through hole 112 is formed therein.

파이프(120)는 그 일측이 상기 머플러(1)에 고정되어 있고 타측이 상기 진동흡수재(110)의 관통홀(112)내에 삽입되어 있다. 상기 파이프(120)의 중간에는 상기 파이프(120)의 진행을 제한하는 돌기(122)가 형성되어 있다.One end of the pipe 120 is fixed to the muffler 1, and the other end of the pipe 120 is inserted into the through hole 112 of the vibration absorbing member 110. In the middle of the pipe 120, a protrusion 122 for limiting the progress of the pipe 120 is formed.

그리고, 볼트(140)는 너트(130)를 개재하여 상기 파이프(120)의 끝단에 결합되어 있다.The bolt 140 is coupled to the end of the pipe 120 via the nut 130.

도 5에 도시된 바와같이, 진동흡수재(110)는 그 내부에 상기 관통홀(112)을 중심으로 4개의 방사형 발(114)이 형성되고, 관통홀(112)의 중간에는 진동흡수재(110)의 변형을 방지하기 위한 보강링(116)이 마련되어 있다.As shown in FIG. 5, the vibration absorber 110 has four radial feet 114 formed around the through hole 112 therein, and the vibration absorber 110 in the middle of the through hole 112. The reinforcing ring 116 is provided to prevent the deformation of the.

이와같이 구성된 자동차의 머플러 행거장치의 작용을 설명하면 다음과 같다.Referring to the operation of the muffler hanger device of the vehicle thus configured as follows.

도 3 및 도 4를 참조하여 각 구성부품을 조립하는 과정을 살펴보면 우선, 진동방지재(110)를 볼트(3a) 체결하여 차체프레임(3)에 고정한다. 그 다음 머플러(1)에 고정된 브라켓(2)에 연결된 파이프(130)를 진동방지재(110)의 관통홀(112)에 삽입한다.Looking at the process of assembling each component with reference to Figures 3 and 4, first, the vibration damping member 110 is fastened to the vehicle body frame 3 by fastening the bolt (3a). Then, the pipe 130 connected to the bracket 2 fixed to the muffler 1 is inserted into the through hole 112 of the vibration damping material 110.

이 상태에서 파이프(120)의 반대측에서 너트(130)를 개재하여 볼트(140)를 진동방지재(110)의 관통홀(112)내, 보다 정확하게는 파이프(120)의 끝단에 삽입 결합시킨다.In this state, the bolt 140 is inserted into and coupled to the end of the pipe 120 more accurately in the through hole 112 of the vibration damping material 110 via the nut 130 on the opposite side of the pipe 120.

이렇게 파이프(120)에 볼트(140)를 체결함으로써 머플러(1)가 진동방지재(110)를 사이에 두고 차체 프레임(3)에 고정되는 것이다.By fastening the bolts 140 to the pipe 120 as described above, the muffler 1 is fixed to the vehicle body frame 3 with the vibration preventing member 110 interposed therebetween.

이상에서와 같이 각 구성부품의 조립이 완성되면 머플러(1)의 진동이 발생되더라도 4개의 발(114)에 의해서 상하 진동이 흡수됨은 물론 파이프(120) 및 너트(130)를 개재한 볼트(140)의 결합에 의해서 전후 좌우 진동이 효과적으로 흡수되는 것이다.As described above, even if the vibration of the muffler 1 is completed when the assembly of each component is completed, the upper and lower vibrations are absorbed by the four feet 114 as well as the bolt 140 via the pipe 120 and the nut 130. ), The front and rear left and right vibrations are effectively absorbed.

또한, 볼트(140)에 너트(130)를 개재함으로써 볼트(140)가 파이프(120)에 견고하게 고정되며, 진동흡수재(110)의 중간에 보강링(116)을 형성함으로써 머플러(1)가 심하게 진동하더라도 진동흡수재(110)가 크게 변형되는 것이 방지된다.In addition, the bolt 140 is firmly fixed to the pipe 120 by interposing the nut 130 to the bolt 140, and the muffler 1 is formed by forming a reinforcing ring 116 in the middle of the vibration absorber 110. Even if vibrating severely, the vibration absorbing member 110 is prevented from being greatly deformed.

이상에서와 같이 본 발명은 머플러의 진동을 흡수함에 있어서 상하 진동은 물론 전후좌우 진동을 모두 효과적으로 흡수할 수 있어 성능이 향상된 효과가 있다.As described above, the present invention can effectively absorb both vertical vibration as well as front, rear, left and right vibrations in absorbing the vibration of the muffler, thereby improving performance.

그리고, 전후좌우 변위의 규제가 가능하여 NVH 증대 효과가 매우 크다.In addition, the front, rear, left and right displacement can be regulated, and the NVH increase effect is very large.

또한, 부품수 및 공정수를 줄일 수 있으며, NVH 증대 효과로 승객의 편의가 증대된다.In addition, the number of parts and processes can be reduced, and the convenience of passengers is increased by the NVH increase effect.
