Abstract
An improved composite air spring with a simplified construction is disclosed. The piston is has a series of internal floating ribs. The ribs extend from the underside of the piston platform to the lower end of the piston. Circumferential forces acting on the piston when the sleeve rolls down onto the piston are absorbed by the piston and the floating ribs.
