本发明提供了一种公铁两用车转向系统,包括前桥液压转向系统回路及后桥液压转向系统回路,前桥液压转向系统回路包括第一油泵、单路稳定分流阀、电磁换向阀、转向器、第一防冲击阀及两个第一液压油缸;后桥液压转向系统回路包括第二油泵、电比例换向阀、压差传感器、梭阀、节流塞、溢流阀、第二防冲击阀及两个第二液压油缸;其中一个第一液压油缸设有第一距离传感器,其中一个第二液压油缸设有第二距离传感器,前桥液压转向系统回路与后桥液压转向系统回路共用一个液压油箱。本发明可以实现公铁两用车的单桥转向和双桥同步转向,能够减小了车辆的转弯半径,使其公路、铁路作业切换的灵活性更好。
The invention provides a highway-railway dual-purpose vehicle steering system which comprises a front axle hydraulic steering system loop and a rear axle hydraulic steering system loop, and the frontaxle hydraulic steering system loop comprises a first oil pump, a one-way stable diverter valve, an electromagnetic reversing valve, a steering gear, a first anti-impact valve and two first hydraulicoil cylinders; the rear axle hydraulic steering system loop comprises a second oil pump, an electric proportional reversing valve, a differential pressure sensor, a shuttle valve, a throttle plug, anoverflow valve, a second anti-impact valve and two second hydraulic oil cylinders; one first hydraulic oil cylinder is provided with a first distance sensor, one second hydraulic oil cylinder is provided with a second distance sensor, and the front axle hydraulic steering system loop and the rear axle hydraulic steering system loop share one hydraulic oil tank. Single-axle steering and double-axlesynchronous steering of the highway-railway dual-purpose vehicle can be achieved, the turning radius of the vehicle can be reduced, and the flexibility of highway and railway operation switching of the vehicle is better.
