缓冲器能降低调车时和列车中的纵向力,因而减少机车车辆和所运货物的损失,所以研制缓冲器是一个迫切的任务。除了苏联研制大容量缓冲器的经验外,研究其他国家的最新成果具有重大的意义。特别是卡德威尔——威斯汀豪斯公司的H-60型液压摩擦缓冲器引起很大的兴趣。该缓冲器供四轴货车用,其轮廓尺寸与苏联制造的缓冲器相同。 H—60型缓冲器(图1)为平板式结构。缓冲器箱体内有摩擦部件和支承组合件。摩擦部件的 The bumper reduces the longitudinal forces in the shunting and in the train, thus reducing the loss of the rolling stock and the goods transported. Therefore, the development of the bumper is an urgent task. In addition to the Soviet Union’s experience in developing large-capacity buffers, it is of great significance to study the latest achievements of other countries. In particular, the Cadenville-Westinghouse H-60 ​​type hydraulic friction damper is of great interest. The buffer for four-axis trucks, the outline of the size and the Soviet-made buffer the same. H-60 type buffer (Figure 1) for the flat structure. The bumper box has frictional components and support assemblies. Friction parts
