<p>An air spring sleeve. The sleeve comprises an elastomer body having two plies. Each ply comprises a cord embedded in the elastomer body. Each cord is wound about the sleeve in an opposing direction from the other and each having a helix . The first cord helix angle and the second cord helix angle comprise a cord differential helix angle. The first or inner cord helix angle is greater than a second or outer cord helix angle. The cord differential helix angle is in the range of approximately 0o to 2.5o.</p> |
