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 substantially frustoconical and the second piston is substantially cylindrical and where the minimum effective area of the first piston is less than the minimum effective area of the second piston and where the maximum effective area of the first piston is greater than the maximum effective area of the second piston. The frustoconical first piston allows the air spring to accommodate large angular suspension motion without degrading durability. |
