Abstract
An air spring assembly having a flexible member and moveable piston is provided. A bead surface of the flexible member is secured into a channel 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.
