More Information
Summary:A bellows type air spring having a circular lobed body member with an inner an outer rubberized fabric reinforcing ply and a bead ring at each end. The turn up portion at each end of the fabric layers is wrapped around the bead ring with the turn up portion of the inner ply extending axially inwardly from the bead ring a substantial distance beyond the end of the turn up portion of the outer ply on both ends of the spring to provide longer flex life and prevent premature cracking of the body member in the areas of the end bead rings. The manufacturing method involves the use of an inner fabric ply that is substantially longer in the axial direction than the outer ply instead of using both inner plies of the same axial length.
