一方面在促进铁道车辆的高速化时，另一方面需要降低维修面本。在普通线路上业已证明，非石棉闸瓦衬和低合金铸铁制动盘的结合显示出良好的特性。为了将钢质制动盘付诸实际应用，有必要开发一种用于钢盘的闸瓦衬，以期满足普通线路上高速铁道车辆的需要。钢盘在新干线上的应用 On the one hand, when promoting the speeding up of railway vehicles, on the other hand, there is a need to reduce the maintenance surface. It has been shown on common lines that the combination of a non-asbestos brake lining and a low alloy cast iron brake disc shows good characteristics. In order to put the steel brake disc into practical use, it is necessary to develop a brake lining for the steel disc to meet the needs of high-speed railway vehicles on ordinary lines.
