Abstract
An exemplary self-balancing air spring includes a first chamber, the first chamber defining a primary volume, the first chamber including a movable piston, a second chamber fluidicly coupled to the first chamber via a first orifice and a second orifice, the second chamber defining a secondary volume, and an actuator coupled to the movable piston. In some aspects, the first orifice is an electromechanical valve and the second orifice is a bleed valve that equalizes the pressure between the first and second chambers.
