The present invention relates to a mounting structure of an exhaust pipe where exhaust gas generated in an engine flows, comprising: an exhaust pipe; and an insulating mount fixedly mounted to a vehicle body member in which an insulator made of elastic material is embedded and a fastening bolt coupled to the insulator protrudes from the outside to be connected to the exhaust pipe. In addition, vibration generated in the exhaust pipe is transferred to the insulator via the fastening bolt, and is absorbed by elastic deformation in material of the insulator. According to the present invention, the insulating mount used for a vibration reduction purpose instead of a flexible tube is mounted such that production costs can be reduced by improving NVH performance and eliminating the flexible tube.
본 발명은, 엔진에서 생성된 배기가스가 유동하는 배기파이프의 장착구조에 있어서, 배기파이프; 및 차체부재에 고정장착되되, 탄성을 갖는 재질로 제조된 인슐레이터가 내장되고 상기 인슐레이터와 결합된 체결볼트가 외부로 돌출되어 상기 체결볼트가 배기파이프와 연결되는 절연마운트;를 포함하며, 상기 배기파이프에서 발생하는 진동은 체결볼트를 통해 인슐레이터로 전달되고 상기 인슐레이터 재질의 탄성변형에 의해 흡수되는 것을 특징으로 한다. 전술한 바와 같은 구성을 갖는 본 발명은 플렉시블튜브를 대신하여 진동 감쇠 전용으로 사용되는 절연마운트가 장착되므로 NVH 성능을 증대시킬 수 있고 플렉시블튜브를 삭제하여 생산원가를 증대시킬 수 있다.
