发明名称 Variable rate leaf spring construction
摘要 A variable rate leaf spring construction for a vehicle including a composite leaf spring composed of fiber reinforced resin. The ends of the spring are adapted to be connected to the frame of the vehicle and an axle is mounted to the central portion of the spring. A resilient bumper is mounted on the frame and is disposed to be engaged by the spring as a load is applied to the frame. The bumper is tapered downwardly and the lower end of the bumper terminates in a generally rounded tip. The rounded tip provides a low or soft spring rate on initial contact with the leaf spring, while further loading will compress the bumper to provide a higher spring rate.
