AIR SPRING FOR MOVING BODY AND TRUCK FOR MOVING BODY

WIPO Patent Application WO/2011/004742

A1

Provided is an air spring to obtain a moving vehicle which provides a comfortable ride even when passing through a curve. The air spring for a moving body is provided with an outer cylinder, a lower surface plate and a diaphragm, and a rubber stopper provided between the lower surface plate and a holding plate. The air spring is provided with a displacement restriction mechanism for the rubber stopper, which is comprised of a first stopper provided on one of the holding plate and the lower surface plate and second stoppers which are provided on the other. Stop wall surfaces are shaped so that identical distances are maintained between the first stopper and the second stoppers, in a relative positional relationship between the first stopper and the second stoppers when the first or second stoppers are displaced along an arc having a center on a truck axle of a truck of the moving body. Or, the stop wall surfaces are shaped so that the distances between the first stopper and the second stoppers decrease as the amount of the displacement along the arc increases.
