CAR BODY TILT CONTROL DEVICE FOR ROLLING STOCK AND ITS CAR BODY TILT CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To accurately control tilt displacement when a car body is tilted, perform ordinary car body tilt control when the device is in failure. ;SOLUTION: A car body tilt control device is provided, in which a tilt beam 3 is interposed between a car body 1 and a bogie 2, in an actuator 5 suspension supported to both ends of the tilt beam 3, both ends of a torsion bar 6 horizontally provided between side beams of the bogie 2 are flexibly connected through a link 7. Height adjusting valves 10a, 10b, 10c of air spring are set up in three parts of right/left sides and center between the bogie and the tilt beam. Between an air source 13 and right/left air spring 9 is connected by a pipe 11 by interposing the right/left height adjusting valves 10a, 10b, between the right/left air springs is connected by a pipe 12, between a pipe central part and the air source 13 is connected by a pipe 11 by interposing the height adjusting valve 10c in the center, in the halfway of a pipe between each height adjusting valve and the right/left air spring, opening/closing control valves 14a, 14b are provided.;COPYRIGHT: (C)1998,JPO
