8K型电力机车使用的停车制动器为FSS216G型弹簧止轮器。这种止轮器具有使用方便、制动性能强等优点,可以使机车制停在36‰的坡道上。但我们在长期使用中也发现其在设计上存在着一定缺陷,其中因止轮器制动缸活塞皮碗破损漏风或连接软管破损等原因而造成的弹簧止轮器非正常上闸,即为较突出的问题。由于弹簧止轮器非正常上闸时司机室监视装置无显示,不能及时警示司机及早排除故障,易造成 The parking brake used on the 8K electric locomotive is the FSS216G spring stop. This type of stop has the advantages of easy to use and strong braking performance, which can make the locomotive stop at a ramp of 36 ‰. However, we also found some shortcomings in the long-term use of its design, which is due to brake wheel piston piston cup damaged air leakage or connection hose damage and other reasons caused the spring stop wheel abnormal gate, that is For more prominent problems. As the spring stop wheel brake abnormal monitoring unit no display, can not promptly alert the driver as early as possible to troubleshoot, easy to cause
