Abstract
A hydraulically assisted steering system comprises a steering gear operatively connected to a steering wheel and to a set of steerable wheels to effect turning of the steerable wheels in response to rotation of the steering wheel. A hydraulic motor is operatively connected to the set of steerable wheels to assist in turning of the steerable wheels. A pump is fluidly connected to the hydraulic motor to deliver a flow of fluid to the hydraulic motor via a flow path from the hydraulic pump to the hydraulic motor. The flow path from the hydraulic pump to the hydraulic motor is free of any rotary steering control valve. Pressure control apparatus monitors and adjusts hydraulic fluid pressure in the hydraulic motor. The pressure control apparatus adjusts hydraulic fluid pressure in the hydraulic motor by controlling one of pump speed and pump displacement. Direction control apparatus controls direction of hydraulic fluid flow to the hydraulic motor.
