PUSHER AXLE SUSPENSION SYSTEM HAVING SINGLE AIR SPRING

摘要

A pusher axle suspension system having a single air spring includes a pair of frames having mounting brackets integrally formed at lower front portions of the pair of frames, respectively. A link arm includes a front end connected to each mounting bracket of the pair of frames by a mounting bush. Axle sheets are disposed at lower portions of the pair of frames, respectively, to support a pusher axle. The axle sheets are connected to a rear end of the link arm by a hinge. A composite air spring is provided between a rear end of the axle sheet and a bottom surface of the pair of frames. The composite air spring moves the axle sheet upward or downward to adjust a height of the pusher axle and to absorb vibration due to a road surface during traveling.
