Problems solved by technology

[0013] However, the existing pushrod type axle suspension system needs to lift the air spring 109 and the suspension spring 111, thereby complicating the structure together with the air supply system and reducing productivity
[0014] In addition, when the axle plate 103 is operated up / down by lifting the air spring 109, the load is concentrated on the mounting bush to connect the axle plate 103 and the lift arm 107 with the front frame 101, so that the mounting bush shortened service life

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2014-0155663 filed in the Korean Intellectual Property Office on Nov. 10, 2014, the entire contents of which are incorporated herein by reference. technical field [0003] This application relates to pushrod axle suspension systems. More particularly, the present application relates to a pushrod axle suspension system having a single air spring capable of performing the functions of both a lift air spring and a ride air spring. Background technique [0004] In a pushrod axle suspension system for a vehicle, the rear wheel axle of a large vehicle (eg, a vehicle with five axles) moves up when the vehicle is unloaded, and moves down when the vehicle is loaded. That is, when the vehicle is unladen, the travel resistance is reduced by moving the pushrod axle up when the pushrod axle tends to move down. When the vehicle is loaded, the acc...
