PURPOSE: To obtain a desired distribution of roll rigidity without causing any change in the posture of a vehicle by dividing a liquid pressure control system into two lines of the left front wheel/right rear wheel and the right front wheel/ left front wheel, and so constructing that the increase and decrease of pressure of the same value will be applied simultaneously to these control lines.
CONSTITUTION: On each wheel 11FL-11RR, oil hydraulic cylinders 10(10FL-10RR), the upper end of which are connected to a car body 12 side, are installed. Ports 10a of each oil hydraulic cylinder 10 of the left front wheel and right rear wheel are communicated with an oil passage 14, and ports 10a of oil hydraulic cylinders 10 of the right front wheel and left rear wheel are communicated with an oil passage 15. Accumulators 16, 17 are installed on each oil passage 14, 15, and a variable hydraulic cylinder 18 is inserted between oil passages 14, 15. The variable hydraulic cylinder 18 is so constructed that the hydraulic pressure of hydraulic pressure chambers 18b, 18c can be adjusted with the stroke of a piston 18a, and that the hydraulic pressure of one of two hydraulic pressure control lines can be increased while that of the other can be reduced simultaneously by the same pressure value.
