The invention relates to a hydraulic steering system, and aims at overcoming the defect that an existing hydraulic steering system is large in impact. The hydraulic steering system comprises steering cylinders, a flow amplifying valve, a steering pump and a steering device, the steering pump is connected with the steering device and the flow amplifying valve, the steering cylinders are connected with the flow amplifying valve, the steering pump supplies oil to the steering pump through the flow amplifying valve, and the control output end of the steering device is connected with the hydraulic control end of the flow amplifying valve; the hydraulic steering system further comprises a control device, and normally open solenoid valves are connected between the control output end of the steering device and the hydraulic control end of the flow amplifying valve; the control device comprises trigger mechanisms which send out trigger signals when the steering cylinders stretch and retract to preset positions, and the control device is connected with the electronic control ends of the solenoid valves and closes the solenoid valves when the trigger mechanisms give out the trigger signals. According to the hydraulic steering system, non-contact cutting is adopted by a steering buffer limiting technology, and the impact force is reduced; steering is smooth and comfortable, a part which needs to be cut off and steered is not prone to damage and invalidation, and the steering reliability of a whole machine is improved.
