METHOD FOR PRODUCING A HYBRID LEAF SPRING

摘要

In a method for making a hybrid leaf spring, at least one layer of composite material is molded onto a primary leaf (60) using a mold (62) with an interior cavity (64) having a curvature for receiving the primary leaf at a depressed camber (C2) relative to its initial camber (C1). The depressed camber is between unloaded and curb load cambers of the hybrid leaf spring. The primary leaf and the layer of composite material are positioned in the mold adjacent to one another and with a layer of adhesive therebetween. The layer of adhesive is cured for bonding together the primary leaf and the layer of composite material at the depressed camber so as to generally eliminate bond line shear stress when the camber of the hybrid leaf spring is at the curb height.
