独立车轮在低地板轻轨车辆上的应用

Application of independently rotating wheels in low-floor light rail vehicles

参考国内外对独立车轮应用于铁路车辆及低地板轻轨车辆所做的理论及试验研究 ,分析讨论了独立车轮的运行特性、可能发生的问题以及应采取的措施 ,特别强调车轮踏面设计的重要性 ,并指出磨耗形踏面的等效斜度概念已不复存在 ,应采取踏面接触角差作为重要设计参数。

A lot of theoretical and experimental research on application of independently rotating wheels for rail vehicles and low floor light rail vehicles has been undertaken at home and abroad. Referring to the aforesaid research, the running behavior, potential problems, and measures to be taken of independently rotating wheels were discussed. Emphasis was put on the importance of wheel profile design. The concept of effective conicity of wear profiles no longer had any meaning for independently rotating wheels and the difference for wheel/rail contact angles between right and left wheels should be used as a key parameter of profile design.
