A Study on Friction Coefficient of Disk Brake Lining for Rolling Stock According to Disk Type

디스크 타입에 따른 철도차량용 디스크 브레이크 라이닝의 마찰계수 특성에 관한 연구

In this study, we investigate the change characteristic of friction coefficient of disk brake lining for rolling stock according to disk type, The actual brake tests were carried out under constant brake force and operating sequence by using dynamo-tester. Test results showed that instant friction coefficient was higher in the case of devided disk type rather than single body disk type, Also, averge friction coefficient was appeared similer to the above result. It is thought that ,in the case of devided disk type, friction resistance was increased due to the gap between both side of half disk.
