Abstract
In a tandem wheel and axle suspension for suspending a vehicle chassis, a flexible joint assembly for connecting the underside of each distal end of a fore-and-aft leaf spring equalizer beam to the subadjacent end of a transverse axle comprising a downwardly projecting spring anchor mounted on the underside of the distal end of the bottom leaf of the leaf spring, a load cushion formed of elastomeric material having an upwardly open socket in which the projecting portion of the spring anchor is embedded, and an axle bracket mounted on the subadjacent end of the axle having an upwardly open socket formation into which the load cushion is seated. An elastomeric rebound cushion is mounted over each distal end to prevent the spring anchor from disengaging the load cushion axle and is without upper torque rods.
