차량용 배기계 행어{Hanger for exhaust assembly of automobile}Hanger for exhaust assembly of automobile

본 발명은 배기계가 차량의 바닥부에 고정될 수 있도록 배기계를 지지하는 차량용 배기계 행어에 관한 것이다.The present invention relates to a vehicle exhaust system hanger for supporting the exhaust system so that the exhaust system can be fixed to the bottom of the vehicle.

일반적으로, 도 1에 도시된 바와 같이, 배기계(100)는 차량(100) 하부에 위치하며, 배기파이프, 머플러와 같은 배기계(110)의 구성부품이 차량(100) 바닥부에 고무 재질의 행어(120)를 이용하여 차량 바닥부에 고정된다.In general, as shown in FIG. 1, the exhaust system 100 is located under the vehicle 100, and components of the exhaust system 110, such as an exhaust pipe and a muffler, have a rubber hanger at the bottom of the vehicle 100. It is fixed to the vehicle bottom using the 120.

이러한 배기계(110)에는 엔진 진동, 배기가스유동 등으로 인해 진동이 발생하고, 주행 중 차량(100)의 움직임에 다른 관성력에 의해 움직이게 되는데, 이러한 진동 및 움직임에 의한 하중이 행어(120)를 통해 차체에 전달된다.Vibration is generated in the exhaust system 110 due to engine vibration, exhaust gas flow, and the like, and is moved by other inertial force to the movement of the vehicle 100 while driving. Delivered to the body.

따라서, 행어(120)는 배기계(110)에서 발생된 진동이나 움직임이 차량(100)에 전달되지 않도록 특성이 부드럽게 설정되어야 한다.Therefore, the hanger 120 should be set smoothly so that the vibration or movement generated in the exhaust system 110 is not transmitted to the vehicle 100.

하지만, 행어(120)의 특성이 부드러워지면, 도 1에 화살표 A로 도시된 바와 같이 배기계(110)가 처질 수 있고, 차량(100) 주행중 발생하는 관성력에 의한 배기 계(110)의 움직임도 커지고, 차체, 서스펜션 등의 주변 부품과 간섭 및 파손이 발생하는 문제점이 있다.However, when the characteristics of the hanger 120 are softened, the exhaust system 110 may sag as illustrated by arrow A in FIG. 1, and the movement of the exhaust system 110 due to the inertial force generated while driving the vehicle 100 also increases. There is a problem in that interference and breakage occur with peripheral components such as a vehicle body and a suspension.

또한, 배기계(110)의 움직임이 크면, 배기계(110) 주변의 공간을 크게 확보해야되고, 도 1에 'B'로 표시된 바와 같이 주행 중 돌기(102)를 넘거나 상하방향 충격시 지면과 가까워져 파손되는 문제점이 있다.In addition, when the movement of the exhaust system 110 is large, the space around the exhaust system 110 must be largely secured, and as shown by 'B' in FIG. 1, the protrusion 102 is overrun or close to the ground during the vertical impact. There is a problem that is broken.
