Abstract

치차 변환 변속기의 싱크로 장치의 싱크로링(1)과/또는 카프링링(2)은 내마모성면을 가진 철소재로 되어있다.고 크롬 함유량의 페라이트나 오스테나이트 강으로 최소한 최적비 30%의 카바이트를 함유한 최소 20㎛ 두께로된 카바이트가 풍만한 영역이 그의 표면층으로 사용된다. 마찰카프링은 이에 따라서 그의 마찰표면들은 마모/접착마멸이 적게 된다.The synchro ring (1) and/or the coupling ring (2) of the synchro unit of the gear shift transmission are made of iron material with a wear-resistant surface. Ferritic or austenitic steel with a high chromium content, containing at least 30% carbide in optimum ratio. A carbide-rich region with a thickness of at least 20 μm is used as its surface layer. The friction coupling is thus less prone to wear/adhesive wear on its friction surfaces.
