Abstract
An air spring of the type with a sleeve having a first rolling lobe connected at an end to a first piston, a second rolling lobe connected to an end to a second piston, and where the first piston is substantiallyfrustoconicalcylindricaland the second piston is substantiallycylindricalfrustoconicaland where the minimum effective area of thefirstsecondpiston is less than the minimum effective area of thesecondfirstpiston and where the maximum effective area of thefirstsecondpiston is greater than the maximum effective area of thesecondfirstpiston. The frustoconicalfirstsecondpiston allows the air spring to accommodate large angular suspension motion without degrading durability.
