Spring beam suspension system

摘要

A suspension system includes a pair of spring beams with each spring beam pivotally mounted to a hanger bracket extending downwardly from a vehicle. An axle seat is mounted to an end of each spring beam and includes a passage extending therethrough. The spring beam passes through the passage formed in the axle seat and is permitted to deflect in response to vertical loads within the passage. A resilient bushing is positioned within the passage and intermediate the axle seat and the spring beam to permit the spring beam to assist in retaining the axle seat onto the beam, and to assure that the spring beam may flex along its entire length. The axle seat is retained on the spring beam by the pin connection extending through an eyelet formed in one end of the spring beam. In alternative embodiments, one end of the spring beam is movable relative to either the hanger bracket or the axle seat with the axle seat being retained on the spring beam by an adjustable link mounted via a pair of mounting pins to the hanger bracket or mounting hood and to the axle seat.
