The invention provides a steering hydraulic system which is characterized in that the system comprises a power unit, the power unit is connected with a plurality of damping hydraulic cylinders so as to provide power hydraulic oil for the damping hydraulic cylinders, and a control oil way of each damping hydraulic cylinder comprises a displacement closed-loop control oil way and a hydraulic cylinder damping oil way; pressure sensors are arranged in control oil ways of the damping hydraulic cylinders to monitor oil way pressure values in real time, and the electric control unit is in signal connection with the pressure sensors so as to correspondingly switch the control oil ways of the damping hydraulic cylinders according to the real-time oil way pressure detected by the pressure sensors. Therefore, different corresponding control oil ways are selected for the hydraulic system according to different vehicle running conditions.

    本发明提供一种转向液压系统,其特征在于:所述系统包括动力单元,所述动力单元分别与若干减震液压缸连接,以分别向若干减震液压缸提供动力液压油:每个所述减震液压缸的控制油路均包括位移闭环控制油路和液压缸减震阻尼油路;且在各减震液压缸的控制油路中设置有压力传感器实时监测油路压力值,电控单元与压力传感器信号连接,以根据压力传感器检测到的实时油路压力对减震液压缸的控制油路进行对应切换;从而根据不同的车辆行驶状况为液压系统选择对应不同的控制油路。
