However, the disc brake has larger power, its friction coefficient is stable, which can reduce the wheel tread wear. 由于盘形制动功率大、摩擦系数稳定,同时还可减小车轮踏面磨耗,一般在速度高于120km、h的列车上普遍采用盘形制动。
It is assumed as main factor which are pressure difference of master cylinder, disc process, friction variation and wheel alignment. 定义本文制动跑偏影响因素为制动主缸压差、制动盘、摩擦系数变差和车轮定位参数。
