PURPOSE:To stabilize a posture of a car body at the time of its running at a curve, by so constituting that hydraulic pressure is fed to an ascending and descending cylinder of an external frame material of the curve by passing a fluid to be discharged by operation of a steering wheel through a throttle valve and by actuating a directional control valve for a feed liquid through the fluid of more than a passable quantity. CONSTITUTION:When a steering wheel 7 is operated hastily in a direction of arrow shown on a sketch a fluid of high pressure is returned to a tank 11 from a fluid discharge opening of a right side booster cylinder 10b through a throttle valve 13. At this time the fluid of more than a passable quantity through the throttle valve 13 acts upon a directional control valve 22b for a feed liquid as directional control pressure and opens the directional control valve 22b and a relief valve 25. A surplus high pressure fluid, therefore, is returned to a tank 11 and hydraulic oil is streamed into an upper chamber 6 of an ascending and descending cylinder 4 for a right side frame material from a pressure generator 16 through the directional control valve 22b and a feed duct 15b for lifting the frame. A car body at the time of running at a curve can be kept at an identical posture with that available at the time of running on an inclined road. |
