The invention relates to a steering system. The steering system comprises: a first steering axle being a double contrapositive steering axle and comprising a first oil port and a second oil port; a second steering axle comprising a fifth oil port and a sixth oil port; a steering gear communicated with the first oil port and the fifth oil port through a first steering oil port, communicated with the second oil port and the sixth oil port through a second steering oil port, and configured to control the flow direction of hydraulic oil of the first steering oil port and the second steering oil port according to a steering instruction; and a first hydraulic valve group arranged on a flow path from the steering gear to the first steering axle and the second steering axle, and configured to selectively communicate the first steering oil port with the first oil port and/or the fifth oil port and selectively communicate the second steering oil port with the second oil port and/or the sixth oilport according to a mode selection instruction. According to the embodiment of the invention, the operation convenience of the steering system can be improved, the response time of the steering system under the control signal is reduced, and the steering angle deviation of the steering system is reduced.

    本公开涉及一种转向系统,包括:第一转向车桥,为双对置油缸转向车桥,包括第一油口和第二油口;第二转向车桥,包括第五油口和第六油口;转向器,通过第一转向油口连通第一油口与第五油口,并通过第二转向油口连通第二油口与第六油口,并被配置为根据转向指令控制第一转向油口和第二转向油口的液压油流向;以及第一液压阀组,设置于转向器流至第一转向车桥和第二转向车桥的流路,并被配置为根据模式选择指令将第一转向油口有选择地连通第一油口和/或第五油口,并将第二转向油口有选择地连通第二油口和/或第六油口。本公开实施例能够提高对转向系统操作的方便性,减少转向系统在控制信号下的响应时间,并降低转向系统的转向角度偏差。
