The invention discloses a full-axle steering system, and relates to the technical field of steering control. A piston rod of the control oil cylinder is connected with the steering wheel steering gear assembly; the front axle steering assembly is connected with a piston rod of the control oil cylinder; piston rods at the two ends of the double-outlet-rod hydraulic cylinder are rotationally connected with the left rear steering pull rod and the right rear steering pull rod correspondingly, the double-outlet-rod hydraulic cylinder is communicated with the control oil cylinder through a first pipeline and a second pipeline, and a two-position two-way reversing valve is arranged on one of the first pipeline and the second pipeline. A two-way overflow valve and a two-position four-way reversing valve are arranged between the first pipeline and the second pipeline, and the two-way overflow valve is close to the control oil cylinder. The controller is electrically connected with the two-way overflow valve, the two-position two-way reversing valve and the two-position four-way reversing valve. According to the invention, during turning, the rear tire can rotate at a certain angle, so that the friction force is reduced, and the tire wear is relieved.

    本发明公开了一种全桥转向系统,涉及转向控制技术领域,包括:方向盘转向器总成;控制油缸,控制油缸的活塞杆与方向盘转向器总成连接;前桥转向总成,前桥转向总成与控制油缸的活塞杆连接;双出杆液压缸,双出杆液压缸的两端的活塞杆分别与左后转向拉杆和右后转向拉杆转动连接,双出杆液压缸与控制油缸通过第一管路和第二管路连通,第一管路和第二管路两者之一上设置有二位二通换向阀,第一管路和第二管路之间设置有双向溢流阀和二位四通换向阀,且双向溢流阀靠近控制油缸;控制器,控制器分别与双向溢流阀、二位二通换向阀和二位四通换向阀电连接。本发明能够实现在转弯时,后轮胎能够发生一定角度的转动,减小摩擦力,减轻轮胎磨损。
