独立车轮转向架在高速车辆中有良好的发展前景 ,但由于缺乏直线复位和曲线转向能力 ,长期没有得到普及和推广。本文通过理论分析和动力学计算表明 ,采取适当措施使独立车轮轮对以拖动的形式前进 ,可以有效解决独立车轮的导向问题。拖动式独立车轮轮对在直线上复位可靠 ,在曲线上借助径向调节装置能够近似地处于轨道的径向位置 ,与传统轮对比较 ,其横向动力学性能大为改善
Independent wheel bogies have good prospects for development in high-speed vehicles but have not been widely adopted and promoted for lack of linear reset and curve steering capabilities. In this paper, theoretical analysis and dynamic calculations show that taking appropriate measures to separate wheel pairs in the form of dragging can effectively solve the problem of guidance of independent wheels. Drag-independent wheelsets are reliably reset on the straight line and can be approximated by the radial adjustment device in the radial position of the track on the curve. Compared with the conventional wheel, the lateral dynamic performance is greatly improved
