Abstract: A suspension for a front double-axle vehicle is provided in which when an axial load is input from either a first front axle or a second front axle, the axial load is transmitted and dispersed to the other axle. The suspension includes an intermediate bracket that is disposed between a front leaf spring coupled to the first front axle and a rear leaf spring coupled to the second front axle. A front shackle is rotatably coupled at a first end thereof to a rear end of the front leaf spring. Additionally, a connector is rotatably coupled at a first end thereof to a second end of the front shackle and at a second end thereof to a front eye end of the rear leaf spring, and is rotatably coupled to the intermediate bracket at an intermediate portion thereof between the first and second ends.

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.
