Abstract

An axle suspension system wherein shock-absorbing members (31, 32) allow vertical movement of an axle (25) relative to a frame (16). Unequal vertical movement of the ends of the axle (25) is restrained by a torsion bar (40) spaced from and parallel to the axle and mounted (41, 42) on the frame for axial rotation and by rods (46-49) extending between the ends of the torsion bar (40) and the axle (25), the rods each having a non-rotatable connection (53a-d) with the torsion bar (40) and a universal connection (58a-d) with the axle (25). Unequal vertical movement of the ends of the axle (25) imposes a torque on the torsion bar (40) which resists such axle movement The axle suspension system has particular utility in single-axle tractor units of tractor-scraper vehicles.
