Abstract
PURPOSE:To enhance drivability by constituting an oil supply device suitable for a four-wheel steering device delivering oil, decreasing with an increase of car speed, to the first oil line, when the car speed is in a predetermined value or less, and oil, increasing with the increase of car speed, to the second oil line when the car speed is in the predetermined value or more. CONSTITUTION:Delivering working fluid from an oil pump 6, the fluid, governed in its pressure by a servo valve 4, is supplied to a power cylinder 2 in a power steering device, and a spool 41 of the servo valve 4 is driven by an oil hydraulic actuator 8 with working fluid controlled in a hydraulic control valve device 7. Working fluid from a variable displacement oil pump 10 of bidirectional delivery type is supplied to the hydraulic control valve device 7 through oil lines 28, 29. Here the oil pump 10 is connected to a drive shaft 9b integrally formed with a carrier 9a of a planetary gears 9, while respectively connecting a sun gear 9d to an output shaft T/M of a transmission and a ring gear 9e to an output shaft M of an electric motor, the oil pump 10 can be individually driven.
