PROBLEM TO BE SOLVED: To provide a vehicular air spring structure capable of vertically moving a chassis frame without imposing unreasonableness on a diaphragm, by surely connecting an air spring body to a wheel shaft, without using a bolt. SOLUTION: This air spring structure constitutes an air spring body 10 by connecting a load side connecting member 1 and a support side connecting member 11 by a cylindrical piston 12 and the diaphragm 2. The support side connecting member 11 is provided with a fitting installing part 11a or a fitting part 11b for engaging with a projecting part 13a or a recessed part 13b formed in a vehicle side support 13, to thereby dispense with fastening of the support side connecting member 11 and the vehicle side support 13 by the bolt. Thus, installation cost of a device is reduced. A large space for inserting and fastening the bolt is not required, and a comfortable air spring having a large expansion quantity is formed by bringing an air spring near to a wheel shaft body, and the height of a frame and a loading space is lowered to the contrary, to facilitate boarding-alighting and loading-unloading of a cargo. The frame can be lifted, and the wheel shaft can be lowered, without supplying compressed air in the air spring. COPYRIGHT: (C)2005,JPO&NCIPI |
