Abstract

차량의 경량화를 위하여 알루미늄 합금과 같은 열팽창 계수가 큰 재질로 형성된 엔진의 운전 시 크랭크 샤프트를 지지하는 베어링과 열적 팽창율이 달라서 크랭크 샤프트의 지지 구조가 이완되는 것을 방지하기 위해 크랭크 샤프트와 비슷한 열팽창 계수를 갖는 재질의 베어링 지지부를 엔진의 주물 성형시의 인서트 하여 크랭크 샤프트를 효과적으로 지지함으로써 엔진의 성능을 향상시킬 수 있는 효과가 있다.In order to reduce the weight of the vehicle, a bearing supporting the crankshaft is different from a bearing supporting the crankshaft when operating an engine formed of a material having a high coefficient of thermal expansion such as an aluminum alloy so that the support structure of the crankshaft is relaxed to prevent the crankshaft from loosening. There is an effect that the performance of the engine can be improved by inserting a bearing support part of a material having an insert during the casting of the engine to effectively support the crankshaft.
