Abstract:
A suspension assembly between a sprung element and an unsprung element includes an active suspension system having a controllable load-carrying spring element arranged with a negative stiffness element between the sprung element and the unsprung element. The negative stiffness element has a negative stiffness constant that opposes a positive spring rate of the active suspension system to achieve a zero total spring stiffness of the suspension assembly under static conditions.
