对降低机车车轮轮缘高度的可行性作了初步探讨。首先对我国机车和车辆的车轮轮缘高度作了分析比较,并介绍了美国及原苏联对机车轮缘高度的选取,指出更改机车车轮标准,降低机车轮缘高度3mm,与车辆轮缘高度取为相同是可行的。这样做可以延长踏面磨耗到限的走行公里,同时不会影响车轮的脱轨安全性。 The feasibility of reducing the rim height of locomotive wheels was discussed. Firstly, the wheel rim height of locomotives and vehicles is analyzed and compared. The selection of locomotive rim height by the United States and the former Soviet Union is introduced. It is pointed out that the standard of locomotive wheels should be changed, the wheel rim height should be reduced to 3mm, For the same is feasible. This will extend tread wear to the limit of kilometers traveled while not compromising wheel derailment safety.
