蒸汽机车的机车和煤水车之间,是用楔铁式中间缓冲器连接的。为了使蒸汽机车能顺利地通过曲线,在设计和保养中间缓冲器时,均要求在滑铁与滑铁套之间留3.85毫米间隙。但在机车运行过程中,这一间隙会引起机车的纵向振动和冲击,增加机车运行的不平稳和乘务 Between the steam locomotive and the coal-water truck, a wedge iron intermediate damper is used. In order for the steam locomotive to pass the curve smoothly, a clearance of 3.85 mm between the skid and the skid was required when designing and maintaining the intermediate bumper. However, during locomotive operation, this gap will cause longitudinal vibration and impact of the locomotive, increasing the locomotive running instability and crew
