Abstract

PURPOSE: To provide a hydraulic reaction force developing mechanism for use in power steering system, in which an stopper arm and a limiting member adapted for engagement with projections of said stopper arm are fitted respectively in a stub shaft and a valve body in the manner that they are freely detachable and can be turned integrally, and hydraulic chambers and reaction pistons are provided in said limiting member, whereby it is enabled to attain smooth control of the steering force.
CONSTITUTION: Stopper arm 12 having a pair of radial projections 13 is fitted in stub shaft 4 in the manner that it is freely detachable and can be turned integrally with the shaft 4. A limiting member formed with recesses 16, into which projections 13 of stopper arm 12 are fitted for limiting the maximum displacement of valve body 6, is fitted in the valve body 6 at the end portion thereof, in the manner that it is freely detachable and can be turned integrally with valve body 6. Further, the limiting member is formed with hydraulic chambers 20 which are opened in the recesses 16 for receiving projections 13, and reaction pistons are disposed in respective hydraulic chambers 20, such that they are extended to their maximum stroke at the neutral position of the handle and come into abutment with projections 13. when displacement of rotational angle is caused, either of the reaction pistons acts steering reaction force to the stub shaft 4 by hydraulit pressure exerted in hydralulic chamber 20 which is sensed by the driver as steering feeling.
