摘要

A rail vehicle (1) comprising: a vehicle body (1) in which passengers board; a chassis (2) having an air spring (6) elastically supporting the vehicle body (1); Air suspension displacement suppressing devices (95) that control the rigidity in a longitudinal direction of the air spring (6); wherein the air suspension displacement suppressing devices (95) are arranged so as to face each other along the longitudinal direction of the vehicle body (1) from both sides of the air spring (6), characterized in that there is provided a control device (7) having a traveling direction of the rail vehicle (1). which is formed of the vehicle body (1) and the chassis (2), and controls the Luftfederverlagerungsunterdrückungsvorrichtungen (95) controls, and that the Luftfederverlagerungsunterdrückungsvorrichtungen (95) each having a cover plate (84) in contact with a membrane (63) of the Air spring (6) passes; and an actuator (81) connected to the cover plate (84) and adjusting a distance between the diaphragm (63) and the cover plate (84).
