摘　　要：详细分析了传统轮对、独立旋转车轮及耦合轮对等3种不同模式轮轨系统的导向机理,认为传统轮对虽然存在蛇行运动,但其自身却具有直线上的自动对中能力和曲线上的自动导向能力,应用也较广;独立旋转车轮虽然不存在蛇行运动,但在直线上的自动复原能力不如传统轮对,近年来在城市轨道车辆上被广泛采用;耦合轮对兼具前二者的优点,但其工程化尚有难度,相信不久的将来会成功地应用于铁道车辆中。Guiding principles of three different modes of wheel.rail systems, traditional wheelset, independently rotating wheel and coupling wheelset, are analyzed in details, It is viewed that despite of the hunting movement of the traditional wheelset, it features automatic centralization in straight line and automatic guiding in curves as well as wide application. The independently rotating wheel is inferior to the traditional wheelset in automatic recovery in straight lines though without hunting movemant and is widely applied in mass transit vehicles. The coupling wheelset features advantages of both modes but is difficult in engineering. It is believed that in the near future it will he successfully applied to rail vehicles.
