| 貨車空重車自動無級調(diào)整裝置技術(shù)分析(37 卷) |
| 英文標題 |
| Technical Analysis on the Automatic Continuously Variable Adjustment Device of Empty and Loaded Freight Cars |
| 摘要 |
| 貨車空重車自動無級調(diào)整裝置為桶形閥體結(jié)構(gòu)，主要部件有錐形彈簧、活塞、活塞外套、調(diào)整彈簧、調(diào)整套、恢復彈簧和作用桿等。該裝置通過控制閥體上端作用桿行程距離，自動調(diào)整制動缸壓力平衡。試驗證明，貨車空重車自動無級調(diào)整裝置能大幅度降低輪對踏面的擦傷，減小貨車提速 |
