Jounce bumpers are the primary component by which vertical wheel travel is limited in our suspensions. Typically, the jounce bumper is composed of closed or open cell urethane material, which has relatively low stiffness at initial compression with highly progressive stiffness at full compression. Due to this highly progressive stiffness at high load, peak loads are extremely sensitive to changes in input energy (affected by road surface, tire size, tire pressure, etc.) A “Dual Rate Jounce Bumper” concept is described that reduces this sensitivity. Additionally, various mechanizations of the concept are described as well as the specific program benefits, where applicable.
