Title: Steering-force controller for power steering apparatus
Inventor: HONAGA SUSUMU
IPC: B62D5/22
Filed: 1984-04-23
Abstract: PURPOSE:To increase the effective area of a reaction piston and vary the necessary steering force by a small differential pressure by constituting the differential pressure generating means for generating the differential pressure corresponding to car speed onto the both sides of the reaction piston. CONSTITUTION:When the car speed exceeds a prescribed value, a solenoid driving circuit 71 is controlled according to the car-speed signal V input into a computer 70, and an electric current corresponding to the car speed is supplied into the solenoid 61 of an electromagnetic flow-rate control valve 52. A movable spool 62 and a valve shaft 63 shift against a spring 64 according to the electric- current value, and the communication area of a communication passage 67 is reduced. A differential pressure is generated between the flow passages 65 and 66 by the throttle action of the passage 67, and introduced into the both chambers of a reaction piston. Though the differential pressure corresponding to the car speed acts onto the piston, the effective area of the reaction piston can be increased, since the reaction piston is fitted into a cylinder chamber concentric to a servo valve, and the necessary pressing reaction force by the reaction piston can be obtained by a small differential pressure.
