ABSTRACT:
A vehicle suspension system in which an auxiliary spring having a lower spring rate than the mainspring provides a resilient ride under empty or lightly loaded conditions by urging the mainspring toward the lower limit of its vertical travel. The auxiliary spring, which can be added to an existing suspension system of conventional design, extends along the underside of the vehicle frame toward a hanger in which the mainspring is inserted. A sliding bracket with an anti-friction liner is carried by the auxiliary spring and engages the mainspring to reduce wear.
The size of the auxiliary spring is minimized by the use of multiple leaves. A pivoted attachment of the auxiliary spring permits its position to be adapted to the dimensions of a particular vehicle by varying the size or configuration of a spacer.
