Abstract (en)
[origin: WO03091082A2] Disclosed is a power-assisted hydraulic steering device in which a metering device feeding a pressurizing agent to steering cylinders is actuated according to a turning angle of the steering wheel. An additional quantity of the pressurizing agent can be directed to the steering cylinders via a control block. The inventive control block is triggered via a control circuit in which a control pressure lying essentially below the load pressure required for transmitting the steering torque on the steering cylinder is effective. Also disclosed is a spring arrangement for the control block. Two springs are connected in parallel, one of which is actuated only once the control slider has been raised to a given position, whereby a characteristic line can be set, according to which the control slider is biased in the zero position by means of a minimal bias, any overlap can be overridden by means of a small difference in the control pressure, and the control pressure range required for notching up the control block is sufficiently large.
