Guided vrhicle

Abstract

In a guided vehicle of air spring suspension for running along exclusive guideways, decreasing of center distance of the left and right air spring to mount air springs of increased dimension and increased load carrying capacity, which decreasing of the center distance induces decrease in rolling stiffness of the vehicle resulting in deteriorated ride quality and also induces difficulty in adjusting vehicle height resulting in spending long time in height adjusting operation, will not be required even when load carrying capacity of air springs is required to be increased in order to comply with increased vehicle load. A plurality of air spring elements are mounted tandem along the longitudinal direction of the vehicle with the air spring elements connected with each other so that air pressure thereof is always equal.

1 . A guided vehicle having air springs to support the vehicle body on axles thereof for traveling exclusive guideways, wherein the air spring is composed of a plurality of air spring elements connected to one another so that their inside rooms are communicated to one another. 
     
     
         2 . A guided vehicle according to  claim 1 , wherein said air spring elements are mounted such that they are arranged tandem along the longitudinal direction of the vehicle and symmetrically with respect to the center line of the axle of the vehicle. 
     
     
         3 . A guided vehicle according to  claim 1 , wherein said plurality of air spring elements are arranged such that the centers of the spring elements are on a circle. 
     
     
         4 . A guided vehicle according to  claim 1 , wherein said plurality of air spring elements are provided with a common cover-dish. 
     
     
         5 . A guided vehicle according to  claim 1 , wherein said plurality of air spring elements are connected via flexible communicating pipes.
