Abstract

This paper is to study the examples for rubber damage and weaken reliability of timing belt, constant velocity joint boot and weather strip in vehicle. The first example, when the service man replaced the new timing-belt of rubber material, he assembled the belt that was weaken it's contact surface because of material transform. He knew the abnormally tearing failure by friction action between belt and sprocket. The second example, it certified the fact that the grease is leaked out boot protecting of constant velocity joint by split of rubber surface because of durability badness. The third example, the weather stripe took the minutely tearing because of damage produced the material transform by crack of chemistry change. It certified the production phenomenon of a tiny noise by coming with outside air because of overlapped the rubber of weather stripe when driving after closing the door. Therefore, the driver must always manage the rubber system part of vehicle.

이 논문은 자동차 타이밍벨트, 등속조인트 부트, 웨더 스트립에 적용되는 고무시스템의 손상이나 내구성 약화에 대한 사례 연구를 하는 것이 목적이다. 첫 번째 사례에서는 신품의 타이밍 벨트를 교환할 때 벨트의 내구성이 떨어진 벨트를 교환하여 타이밍 벨트와 스프로킷의 마찰작용에 의해 비정상적으로 타이밍 벨트 캔버스가 마멸된 것을 확인하였다. 두 번째 사례에서는 등속 조인트에 그리스의 밀봉역할을 하는 고무 부트의 내구성이 떨어져 경화되고 갈라져 이 틈으로 그리스가 누설된 것을 확인하였다. 세 번째 사례에서는 웨더 스트립이 화학적 변화에 따른 균열로 재료 변형이 생겨 웨더 스트립 고무가 찢어졌다. 이러한 현상은 문을 닫을 때 웨더 스트립 고무를 겹쳐지게 해 운행중 외부공기가 유입되어 미세한 소음이 발생되는 것을 확인했다.따라서, 자동차에 적용되는 고무재질의 부품들의 내구성 약화나 손상으로 인한 자동차의 고장사례가 발생하지 않도록 관리하여야 한다.
