METHOD OF ATTACHMENT OF FLEXIBLE MEMBER TO STAMPED STEEL PISTON.

摘要

An air spring assembly having a flexible member (12) and moveable piston (14) is provided. A bead surface (32) of the flexible member is secured into a channel (42) in the moveable piston to create an air-tight seal which can withstand tensile stress. The hollow piston increases the volume of the air reservoir which contributes to a reduction in the spring rate.
