lip 42 for retention on the bead plates 16 18 the ring 28 of fig4 is formed by two stamped metal pieces 44 46 the piece 44 forming the contact surface is similar to the ring 28 of fig1 the second piece 46 is secured to the open trough of the first piece 44 to result in a more structurally stable ring 28 the ring 28 of fig5 is formed of conventional thermoplastic or thermoset materials of the type used to manufacture airspring pistons to obtain the necessary structural stability needed the ring 28 is formed as a series of accordion ribs 48 the outer surface of the ring 28 approximates the contact surface of the other exemplary rings 28 and enables the airsleeve 10 to move in the desired manner fig6 and 6a illustrate another variation of the stamped metal ring 28 the ring 28 has both a radially inner extending flange 40 and a radially outer extending flange 50 the outer extending flange 50 may be continuous about the outer circumference of the ring 28 or the width of the flange 50 may vary when the air spring 10 is to be mounted on a narrow surface such as a beam 52 the edges of the air spring 10 overhang the beam 52 to provide additional reinforcement the flange width is increased to a maximum width at two opposite locations that then contact the beam 52 when the air spring 10 is mounted variations in the present invention are possible in light of the description.
