Composite bead plate and an air spring using the same

摘要

The present invention discloses an air spring comprising a piston, a top plate, a clamp ring, a snap ring, and a flexible member which is affixed to the piston and the top plate, wherein the piston, the top plate and the flexible member define a pressurizable chamber, wherein the snap ring is affixed to the clamp ring, wherein the clamp ring affixes an upper portion of the flexible member to the top plate, wherein the clamp ring affixes the snap ring to the top plate, and wherein the top plate is affixed between the snap ring and the flexible member.

主权项

1. An air spring comprising a piston, a top plate, a clamp ring, a retaining ring, and a flexible member,
wherein the flexible member is affixed to the piston and the top plate, wherein the piston, the top plate and the flexible member define a pressurizable chamber, wherein the clamp ring affixes an upper portion of the flexible member to the top plate and holds the flexible member in the air-tight contact with the top plate, wherein the clamp ring comprises a plurality of clamp ring fingers, wherein the top plate comprises a plurality of top plate fingers, wherein the clamp ring fingers interleave with the top plate fingers, wherein the clamp ring fingers and the top plate fingers jointly form a channel which is adapted to accommodate the retaining ring, and wherein a relative position between the clamp ring and the top plate is substantially fixed by the retaining ring.
