ABSTRACT:
An automotive power steering system including a power steering gear with detent reaction and a control system for the detent reaction. The detent reaction includes an annular collar in a detent pressure chamber, radially shiftable detent balls on a pinion head of the steering gear, and detent grooves in a stub shaft of the steering gear. A tension spring biases the collar to a retracted position away from the detent balls and detent pressure in the pressure chamber urges the collar toward the detent balls for detent reaction. The control system includes a detent pressure valve connecting the detent pressure chamber to a power steering pump between the pump and a rotary control valve of the steering gear. In a low vehicle speed range, the detent pressure valve exhausts the detent pressure chamber so that the detent balls are unloaded. In an intermediate speed range and a high speed range, the detent pressure valve communicates open-center backpressure to the detent pressure chamber to move the annular collar against the detent balls for detent reaction.
