Electronic control power steering reaction force device

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reaction force device for an electronically controlled power steering that assists a steering force as a steering device of a vehicle and more particularly to a reaction force plate and a reaction force piston provided on an input shaft and forming a guide pin around the reaction force piston And four reaction grooves are formed in the one reaction force piston, and one reaction force piston is used to increase the reference pressure according to the vehicle speed to improve the steering stability. And more particularly, to a reaction force device for an electronically controlled power steering capable of reducing the number of machining operations and improving manufacturing performance and manufacturing cost, and improving the function and performance of the apparatus.
