铸铁闸瓦

鉴于铸铁闸瓦和低摩合成闸瓦的摩擦系数均受制动初速影响，所以相关的等效（二次换算）系数要按普通货物列车的制动初速约80km/h进行修正。

In view of the friction coefficient of cast iron brake shoe and low friction composite brake shoe are influenced by initial braking speed , the correlative equal effective ( 2nd conversion ) coefficients should be corrected under initial braking speed at 80 ? km / h.
