PROBLEM TO BE SOLVED: To provide an air spring sufficiently adaptable to a large load difference between the maximum load and the minimum load. SOLUTION: A cylindrically formed laminated rubber 18 is arranged on the upper part of a lower face plate 12. The laminated rubber 18 is constructed by alternately laminating a plurality of ring plates 20 each formed of a metal into a ring shape and a plurality of elastic bodies 22 each formed of a rubber material into a ring shape. Between an upper face plate 32 and an intermediate material 26, a diaphragm 46 is arranged which is formed of a rubber material. A cross-formed through-hole 26A is provided in a central portion of the intermediate material 26. To a second port fitting 34 fixed to the upper face plate 32, a plurality of chains 54 are welded and connected at their ends. The chains 54 are welded and connected at their lower ends to a spherical body 52 through the through-hole 26A of the intermediate material 26. COPYRIGHT: (C)2006,JPO&NCIPI |
