随着列车运行速度的提高 ,转 8A转向架摇枕斜楔摩擦面磨耗板因开焊脱落而导致转向架定位失效的惯性故障越来越多。如在全路货车段修质量评估中 ,14辆被评估的车辆摇枕斜楔摩擦面磨耗板开焊或脱落故障 ,1999年达 17块之多 ,占被鉴定车辆总数的 30 .4 %;2 0 0 0年达 2 0块之多 ,
As the running speed of the train increases, the inertia failure of the turning bogie locating failure caused by turning off the welding wear plate of the turning bogie of turning 8A bogie is more and more frequent. For example, in the assessment of the quality of the entire freight train segment, 14 vehicles were evaluated for failure of the bolster wedge friction surface to open the welding plate or fall off, up to 17 in 1999, accounting for 30.4% of the total number of vehicles identified. As many as 20 in 2000,
