Abstract: An axle suspension includes a vehicular frame and first and second mounting fixtures mounted in spaced relation beneath the vehicular frame. First and second swing arms have first and second ends and are substantially parallel. The first ends are pivotally mounted to the first mounting fixture for vertical pivotal movement about a substantially horizontal first pivot axis. An axle is positioned on top of and perpendicular to the first swing arm and the second swing arm. The axle is mounted toward the second end of the first swing arm and the second swing arm by underlying resilient elastomer bushings wherein limited movement of the axle is accommodated about a substantially horizontal second pivot axis. Air spring suspension is positioned between the axle and the frame wherein pivotal movement in an upward direction about the first pivot axis is dampened.
