ABSTRACT:
A power steering system for use in a large vehicle comprises: a main booster; an auxiliary booster; a main hydraulic line for connecting the main booster to a hydraulic pump; an auxiliary hydraulic line branching off from the main hydraulic line and connecting the auxiliary booster to the hydraulic pump; a control valve disposed in the main hydraulic line; a reaction pressure supply passage for the control valve; a reaction pressure supply-side variable throttle disposed in the reaction pressure supply passage; a reaction pressure relief-side variable throttle disposed in a reaction pressure relief passage for the control valve; and a load sensing valve. A controller opens and closes the variable throttles in response to the vehicle speed to control the flow rate of hydraulic oil flowing into a reaction chamber of the control valve and flowing out from the reaction chamber, and a hydraulic reaction force generated in the control valve is controlled. At that juncture, the load sensing valve is opened and closed in response to the load applied to the main booster, thereby allowing the auxiliary booster to compensate the steering power of the main booster.
