Abstract:
A suspension assembly between a sprung element and an unsprung element includes load-carrying spring arranged in parallel with a negative stiffness element between the sprung element and the unsprung element. The spring is configured with a positive spring rate to support a static load of the sprung element. The negative stiffness element is configured with a negative spring rate and to exert a force opposing the spring rate of the spring. The negative spring rate has a magnitude that cancels the positive spring rate at a zero deflection point of the suspension assembly.
