ABSTRACT:
A vehicle air spring assembly having a pair of spaced end members which sealingly engage a flexible bladder to form an internal air chamber having an internal volume. One of the end members is a bead plate which has an annular outer end portion which is crimped to the bladder to provide an air tight seal therebetween. The end plate has a recessed portion located between the outer end portion which projects into the air chamber to reduce the volume of the air chamber to change the spring characteristic of the air spring. A plurality of reinforcing gussets extend between the recessed portion of the bead plate and a surrounding upstanding wall which extends between the outer end portion and recessed portion to enable the bead plate to be clamped by fasteners against an adjacent vehicle component and resist deformation when subjected to internal pressure.
