AIR SPRING FOR RAILROAD VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide an air spring capable of improving a curved rail travel performance of a railroad vehicle by including a structure of the air spring which allows displacement relative to a car body or a truck frame, for a reduced air spring reactive force, resulting in reduced lateral pressure.SOLUTION: An air spring is provided with an upper surface part which faces a car body of a railroad vehicle and a lower surface part which faces a truck frame, connecting the car body to the truck frame. It includes a position displacement means in which either the upper surface part or the lower surface part is fitted with the air spring along an advancing direction of the railroad vehicle, for displacement.SELECTED DRAWING: Figure 1
