PURPOSE:To enable control of orientation and ensurance of the earthing force of wheels, by a method wherein a device is so constituted such that pressure oil is fed and discharged to and from hydraulic cylinders for both ends of the axles of front and rear wheels through a pressure oil feed and discharge mechanism, and to and from hydraulic cylinders for the axles of intermediate wheels by means of accumulators. CONSTITUTION:Hydraulic cylinders SA1-SA4 for front and rear axles FA and RA control orientation of a car body by feeding and discharging pressure oil, based on detection of car height sensors S2-S4 on a basis of the detecting value of the car height sensor S1 attached to the front axle SA1, through a pressure oil feed and discharge mechanism III with the aid of various valves VC1-VC4. Meanwhile, in intermediate axles NA1 and NA2, a piston reaction force is specified and an earthing force is specified by feeding and discharging the pressure oil to and from hydraulic cylinders SA5 and SA8 by means of accumulators Q5 and Q6 serving as a gas spring. This constitution enables ensurance of earthing togetherwith control of orientation. |
