PURPOSE:To improve the steering stability, particularly in the high speed traveling, by adjusting the working liquid feed/discharge high speed traveling by adjusting the working liquid feed/discharge action by a control valve utilizing the electromagnetic brake power due to the control electric current which is generated in accordance with the traveling state of a vehicle and inputted into the control valve. CONSTITUTION:A car speed signal (v) supplied from a car speed detecting means 25 is inputted into a control electric current generating means 27, and a solenoid valve 16 is perfectly opened by the control electric current (i) of the control electric current generating means 27, and at the same time, the control electric current (i) is supplied into an electromagnet 21, and then the working liquid supplied from a hydraulic pump 65 is supplied into a power cylinder 43 through a variable throttle iL, and supplied into an R chamber 66 through a variable throttle 3R. The working liquid supplied from the R chamber 60 is supplied into an L chamber 62 through the solenoid valve 16, and returned into a reservoir tank 14 through a variable throttle 2L. Since an electromagnetic brake power is generated between the electromagnet 21 and a core 19, the apparent rigidity of the torsion bar 33a of a valve shaft 33 increases, and the opening degree of the solenoid valve 16 reduces, and the assisting force of the power cylinder 43 is reduced. |
