摘　　要：通过理论计算,一方面分析了在制动倍率不变的情况下使用高磷闸瓦易出现擦伤的原因;另一方面又根据制动距离的要求,在制动倍率调整后对高磷闸瓦和中磷闸瓦出现擦伤的概率进行了比较。Via theoretical calculation, on one side, when the braking leverage is constant, the causes to wheel tread flat in application of high phosphor cast iron brake shoe are analyzed; On the other side, according to the requirements of braking distance, after adjustment of the braking leverage, the probabilities of wheel tread flat in high phosphor cast iron brake shoes and medium phosphor cast iron brake shoes are compared.

关 键 词：高磷闸瓦 中磷闸瓦 踏面擦伤 制动倍率 货车
