Wheel tread, wheel, gauge-changeable steering system and vehicle
The invention relates to the technical field of rail transit equipment, and particularly relates to a wheel tread, a wheel, a gauge-changeable steering system and a vehicle. The wheel tread is appliedto a gauge-changeable rail, the rail matched with the wheel tread is provided with at least two rail cants, the wheel tread comprises a rim, a high-taper area, a normal working area and a low-taper area which are connected continuously and smoothly, and the rim and the high-taper area are provided with opposite arc-shaped end faces respectively; a rolling circle is formed in the normal working area, the position where the rolling circle is located is a tread horizontal datum line, and when the rolling circle transversely moves, the normal working area and the rail are matched with corresponding equivalent tapers under each set of gauges and rail cants respectively. The wheel tread can adapt to two or more gauge rail system environments, and can enable a high-speed train to have a good wheel-rail contact relation, so that the train can run more stably.
本发明涉及轨道交通设备技术领域，尤其涉及一种车轮踏面、车轮、变轨距转向系统及车辆。该车轮踏面适用于变轨距轨道，与该车轮踏面相匹配的轨道具有至少两个轨底坡，车轮踏面包括连续平滑连接的轮缘、高锥度区、常工作区和低锥度区，轮缘和高锥度区分别具有相反的弧形端面；常工作区内形成有滚动圆，滚动圆所在位置为踏面水平基准线，滚动圆在横移时，常工作区分别与轨道在各组轨距和轨底坡下匹配有对应的等效锥度。本发明的车轮踏面能够适应两种或两种以上的轨距轨道系统环境，可以使高速列车具有良好的轮轨接触关系，从而使列车运行更加平稳。
