Abstract

A side load compensating air spring piston (20) having an elliptical cross-section. The side load compensating air spring (100) comprises an air spring sleeve (10) forming a chamber and having a rolling lobe (15). One end of the sleeve is attached to a tilted end cap (11) for side load compensation. The other end of the sleeve has a rolling lobe engaged with a piston elliptical outer surface. The piston elliptical outer surface is disposed at a 90° angle to an elliptical stress distribution in the sleeve, thereby rendering the stress distribution uniform in the sleeve rolling lobe portion as it rolls on the piston.
