The system comprises an oil tank, an oil pump, an electromagnetic valve, a steering gear, a first oil cylinder, a second oil cylinder and a flow amplifying valve, the oil pump extracts hydraulic oil from the oil tank and provides pressure oil through an oil outlet of the oil pump, and the electromagnetic valve is provided with a first electromagnetic valve position and a second electromagnetic valve position and used for switching oil paths. The steering gear is provided with an oil inlet, an oil return port, an oil supply port L and an oil supply port R, oil liquid is distributed according to a steering instruction, when the electromagnetic valve is closed, the first oil cylinder small cavity and the second oil cylinder large cavity are controlled to obtain oil or the first oil cylinder large cavity and the second oil cylinder small cavity are controlled to obtain oil, and when the reversing valve is switched, the oil return port is opened. The oil way used for reversing of the reversing valve can be used for supplementing power to the oil cylinders and achieving rapid rotation, when the electromagnetic valve is powered on, hydraulic oil bypasses the flow amplifying valve and directly enters the first oil cylinder large cavity or the second oil cylinder large cavity, slow steering operation is completed, and the applicability and economical efficiency of a steering system are improved by integrating the rapid steering effect and the slow steering effect.

    本发明公开了一种双速转向系统及转向方法,该系统包括油箱、油泵、电磁阀、转向器、第一油缸、第二油缸和流量放大阀,油泵从油箱抽取液压油并通过油泵出油口提供压力油,电磁阀具有第一电磁阀位和第二电磁阀位,用于切换油液路径,转向器具有进油口、回油口及L供油口和R供油口,根据转向指令分配油液,当电磁阀关闭时,控制第一油缸小腔和第二油缸大腔得油或控制第一油缸大腔和第二油缸小腔得油,并且在换向阀切换时,用于换向阀换向的油路能够用于补充油缸动力,实现快速转动,当电磁阀得电时,液压油绕过流量放大阀直接进入第一油缸大腔或第二油缸大腔,完成慢速转向操作,通过兼具快速和慢速转向的效果,从而提高转向系统的适用性和经济性。
