Abstract

The speed change performance of transmissions has become a serious issue because of the increase in the inertia moment that has accompanied increases in engine output and transmission size. Therefore, it is necessary to develop better wear resistant friction materials. In this study, an appropriate sintered friction component for the synchronizer ring of a diesel manual transmission was developed, and its bonding characteristics were analyzed. That is, a process for bonding an Fe-based base material and Cu-based sintered friction material was developed. BSE and EDX analyses of this bonding layer were conducted, along with a shear strength test, to determine the bonding characteristics.

엔진의 출력증대와 이에 따른 변속기의 크기 증가 등으로 인한 회전체의 관성증가로 변속기의 변속성능은 악조건이 되고 있다. 따라서, 이를 해결하기 위하여 내마모성이 높은 마찰소재의 개발이 요구된다. 디젤차량 수동변속기용 싱크로나이저 링에 요구되는 마찰특성에 적합한 소재를 개발하고, 이에 대한 접합 특성을 평가하였다. 즉, 철합금 모재와 동합금계 마찰재를 접합하는 공정을 개발하고, 접합층에 대하여 BSE분석, EDX분석을 수행하여 접합특성을 평가하였으며, 해당 시험편에 대하여 전단강도를 평가하였다.
