Abstract
A leaf spring for a vehicle suspension is formed from a composite material and includes first and second ends that are longitudinally spaced apart from each other. A resilient element is attached to at least one of the first and second ends. The resilient element includes at least one hole that receives a connecting element. The resilient element and the connecting element cooperate to attach the leaf spring to a vehicle structure. In one example, the resilient element comprises a rubber block that is bonded to the leaf spring. In another example, the resilient element comprises a longitudinally orientated bushing that is inserted through a thickness of the leaf spring.
