PAVEMENT ACCELERATED LOADING TESTING APPARATUS WITH GASBAG PNEUMATIC SUSPENSION

摘要

A gasbag type pavement accelerated loading test apparatus is disclosed. The test apparatus comprises a main frame (7), roller wheels (1) and a pneumatic suspension system. The pneumatic suspension consists of gasbags (2), ventilated bolts (5), spokes (6), inflating valve (10) and a communicating shaft (11) constituting an air storing space interconnecting each of the gasbags (2). The air storing space can be inflated or deflated through the inflating valve (10). The gasbags (2) are disposed between the spokes (6) and rockers (3) which are hinge-jointed to the spokes (6).
