AIR SPRING AND RAILWAY VEHICLE

摘要

An air spring 2 includes: an upper surface plate 21; a lower surface plate 22; an elastic film 23 airtightly coupling a peripheral portion of the upper surface plate 21 and a peripheral portion of the lower surface plate 22 to each other to form an air chamber 24 inside the elastic film 23; an elastic stopper 25 connected to the lower surface plate 22; and at least one of an internal pipe 45 or internal wire 55 extending from an upper surface of the upper surface plate 21 to a side surface of the elastic stopper 25. A railcar 100 includes a carbody 11, a bogie 1, an interface plate 90 provided at the carbody 11, and the air spring 2 provided between the interface plate 90 and a bogie frame 3 of the bogie 1. A part of a pipe and/or wire extending between the carbody 11 and bogie 1 of the railcar 100 is constituted by the internal pipe 45 and/or internal wire 55 of the air spring 2.
