Abstract: A hydraulic steering system, comprising a steering pump and a plurality of digital steering cylinder assemblies. Each digital steering cylinder assembly includes a steering cylinder and a digital hydraulic valve configured to selectively communicate a rodless cavity of the steering cylinder with one of the steering pump and a return oil circuit, and communicate a rod cavity of the steering cylinder with the other of the steering pump and the return oil circuit. A controller can be configured to emit a digital pulse signal to a motor and cause the digital hydraulic valve to move towards a first working position or a second working position. A mechanical feedback structure can be configured to be driven by a piston rod of the steering cylinder when the valve core of the digital hydraulic valve moves towards the first working position or the second working position, so as to drive the digital hydraulic valve to return to a neutral position.
