摘　　要：本文通过C80B型敞车在制动管减压50kPa时静态闸瓦压力和制动缸压力检测,统计了段修前和段修后C80B型敞车制动压力和闸瓦压力值,对比分析了段修前后车辆静态闸瓦压力和制动缸压力的变化规律。In this paper,the static brake shoe pressure and brake cylinder pressure of C80B freight were meas-ured when the brake tube was decompressed by 50 kPa.The valucs of brake pressure and brake shoe pressure of C80B freight before and after depot repair were statistically analyzed.The variation pattern of statie brake shoe pressure and brake cylinder pressure of C80B freight before and after regular repair were compared and analyzed.

关 键 词：段修前 段修后 小减压量 静态 闸瓦压力 制动缸压力
