ABSTRACT:
A two-part, spliced air sleeve assembly for use with an air spring damper includes a first corded, resilient sleeve member bonded to a second corded, resilient sleeve member. The bond angles and fabrics of the first sleeve members are selected so that the first sleeve inflates to a smaller diameter than the second sleeve. A first fastener secures the first sleeve member to the second portion of a damper. A second fastener secures the upper sleeve to a piston rod of the damper to form a closed chamber for receiving pressurized fluid. When inflated for operation, the first sleeve has a smaller diameter than the second sleeve.
