PURPOSE: To aim at noninclinization in a car body by controlling each control valve so as to make the absolute value of a difference in the sum of internal pressure in air springs on respective diagonal lines of front and rear trucks, mean height of these right and left air springs and body inclination so as to settle within the respective set values, at a time when a vehicle is stopped at a curved railroad.
CONSTITUTION: Each pressure gauge 17 and height detector 5 are set up in each of air springs 1-4 installed at both right and left sides of front and rear trucks 9, 10 of a railway vehicle. In addition, air supply valves 11-14 and exhaust valves 21-24 are installed in a pipeline 7 and an exhaust pipe for connecting a main air reservoir 6 to each of these air springs 1-4. Then, in a controller 8, set differential pressure and set height are compared with each other, and a control signal is output. At this juncture, when the vehicle is in travel at low speed or in stoppage, internal pressure control is performed so as to make the absolute value of a difference in the sum of internal pressure in the air springs on diagonal lines of the front and rear trucks 9, 10 to settle within the set value, and then inclination control, which makes body inclination to settle within the set value, and air spring height control, which makes means height of right and left air sorings settle within the set value are performed.
