车辆闸瓦,真的只是一般的商品吗?多年来,铁路机械师们是这样看的,尽管闸瓦的生产厂家看法迥然不同。铁路摩擦产品公司(RFPC)市场销售副总经理吉姆·特纳曾解释说:“在早先年代里,铁路用的闸瓦都是铸铁的,把车辆闸瓦作为一项普通的商用产品,这种看法曾经不错。但是从过去这三、四十年对铁路闸瓦材料及设计做出的和有改进来看,情况早已并非如此”。 Brake shoes, really just general merchandise? Over the years, the railway mechanics are like this, despite the different views of the manufacturer of brake shoes. Jim Turner, vice president of marketing for RFPC, explained: “In the previous years, the brake shoes used on the railway were made of cast iron and used as a normal commercial brake shoe. The view has been good, but judging from the improvements made to the railway brake materials and designs in the past three to four decades, the situation has not always been the case. ”
