ABSTRACT:
An air spring apparatus for a vehicle suspension. An active air cylinder and piston of the apparatus are connected in series with the vehicle suspension. An inactive air cylinder constituting an air column extension of the active air cylinder is connected in series with the active air cylinder by an air conduit. The spring rate of the system is automatically adjustable to produce optimum isolation of impulsive forces and to maintain the forces on the road under dynamic conditions essentially equal to those forces under static conditions.
