本文介绍了206、207型转向架有关磨耗性能方面的现场调查情况及其技术经济分析结果,并且与202型转向架进行了比较。主要结论是,206、207型转向架具有良好的磨耗性能,其磨耗件(例如摇枕吊和制动销套等)的更换率及其更换费用比202型转向架低得多,因而表明该转向架具有较好的技术经济指标。文章还对206、207型转向架磨耗性能良好的原因进行了初步结构分析。同时,对存在的问题提出了改进建议。
This paper presents field investigations on the wear properties of 206,207 bogies and their technical and economic analysis and is compared with the 202 bogies. The main conclusion is that the 206,207 bogies have good wear properties and the replacement rates of their wearing parts (such as bolsters and stoppers, etc.) and their replacement costs are much lower than for the 202 bogie, Bogies have good technical and economic indicators. The paper also carried out a preliminary structural analysis of the reason that the 206,207 bogie has good wear performance. At the same time, some suggestions for improvement are put forward.
