The invention discloses a hinged bogie with hydraulic interconnection suspensions, a rubber wheel virtual rail train and a motion control method of the rubber wheel virtual rail train, and relates to the technical field of rail trains. The hinged bogie is provided with two axles, wheels capable of rotating relative to the axles are arranged at the two ends of the axles respectively, and two suspension devices are symmetrically arranged on each axle; the top of the suspension device is connected with the vehicle body; the suspension devices are hydraulic cylinders, and two independent oil ways are arranged among the four hydraulic cylinders of each hinged bogie, so that the four hydraulic cylinders of each hinged bogie form a hydraulic interconnection suspension. Motion modal decoupling can be ingeniously achieved through interconnection of different pipelines, forward design can be conducted on the hydraulic cylinder damping valve and the energy accumulator damping valve according to the optimal damping ratio of vehicle comfort and the optimal damping ratio of anti-roll, and the comfort is improved while the roll performance is greatly improved.

    本发明公开了一种具有液压互联悬架的铰接式转向架、胶轮虚拟轨道列车及其运动控制方法,涉及轨道列车技术领域,该铰接式转向架具有两个车桥,车桥的两端分别设有可相对于车桥转动的车轮,每个车桥上均对称设置有两个悬挂装置,悬挂装置的顶部与车体相接;悬挂装置为液压缸,每个铰接转向架的四个液压缸的之间设置两条独立油路,使每个铰接转向架的四个液压缸构成一个液压互联悬架。本发明通过不同的管路互联可以巧妙地实现运动模态解耦,可针对车辆舒适性最佳阻尼比、抗侧倾最佳阻尼比对液压缸阻尼阀和蓄能器阻尼阀进行正向设计,在极大提升侧倾性能的同时提升舒适性。
