The invention discloses a three-way automatic emergency switching valve, a wheel side driving steering hydraulic system, a wheel set with the system and a vehicle, and provides a steering hydraulic system suitable for a multi-shaft electric drive special vehicle, the reliability and the safety of a steering system of the electric drive vehicle are improved, and when a high-voltage electric drive system of the vehicle breaks down or the vehicle is dragged, the steering hydraulic system can be switched to the three-way automatic emergency switching valve. The front and rear axle steering function can still be realized, and the trafficability of the vehicle is improved; the wheel sets of independent suspension wheel set structures are adopted, the smoothness of the vehicle is improved, and meanwhile the internal space of the vehicle is not occupied; meanwhile, the three-way automatic emergency switching valve and the hydraulic power source system are provided, so that when any one power source fails, the other two power sources can still supply oil to the steering hydraulic system, and the safety of the system is guaranteed; when the three paths of oil sources work normally, two paths of oil sources return oil to the oil tank through the three paths of automatic emergency switching valves, and power consumption is reduced.
本发明公开了一种三路自动应急切换阀、轮边驱动转向液压系统、具备该系统的轮组和车辆,本发明提供了可适用于多轴电驱特种车转向液压系统,提高了电驱车辆的转向系统可靠性与安全性,在车辆高压电驱系统故障或车辆被牵引时,仍可实现前后桥转向功能,提高车辆的通过性;采用独立悬挂轮组结构的轮组,提高车辆的平顺性,同时不占据车辆内部空间;同时提供一种三路自动应急切换阀及液压动力源系统,实现了任一动力源失效时,其它两路动力源仍可以向转向液压系统供油,保证系统安全;当三路油源工作正常时,其中两路油源通过三路自动应急切换阀回油至油箱,降低功耗。
