日本铁道综合技术研究所、上田制动装置有限公司等单位联合开发了弹性结构型合成闸瓦,该种闸瓦既能确保钢轨湿润条件下的制动性能,也可减轻因热负荷导致对车轮的损伤,有效抑制车轮凹陷磨耗。文章介绍了基于开发的闸瓦进行的台架试验、现车的制动性能试验、长期耐久运行试验的结果。 Japan Railway Comprehensive Technology Research Institute, Ueda Brake Co., Ltd. and other units jointly developed a flexible structural type of synthetic brake shoe, brake of this kind of brake shoe can ensure rail wet conditions, but also reduce the heat load caused by the wheel Of the damage, effectively inhibit the wheel recess wear. The paper introduces the bench test based on the developed brake shoe, the braking performance test of the current vehicle and the result of the long-term durability running test.
