The invention discloses a hydraulic steering system, a chassis and an engineering vehicle, and relates to the field of engineering machinery. The hydraulic steering system comprises a pump, a steeringoil cylinder, a reversing valve and a control assembly. The pump is configured to provide hydraulic oil. The reversing valve is provided between the pump and the steering cylinder, and is configuredto switch an operation of the steering cylinder. The control assembly is connected with the reversing valves and is constructed to switch the valve positions of the reversing valves. The number of thesteering oil cylinders and the number of the reversing valves are both multiple, and the steering oil cylinders and the reversing valves are correspondingly arranged.
