Air spring upper retainer

摘要

An air spring ( 1 ) has a cylindrical flexible sleeve ( 2 ) secured at each end to form a fluid chamber ( 14 ). One end ( 6 ) of the sleeve ( 2 ) is secured to a retainer ( 8 ). The retainer ( 8 ) has a ribbed reinforcement structure ( 16 ) which allows the air spring ( 1 ) to be directly mounted to a moveable part of a vehicle or other machinery. The retainer ( 8 ) has an extending mounting structure ( 13 ) on one side of the reinforcement structure ( 16 ) and a bead-seating surface ( 12 ) adjacent to the reinforcement structure ( 16 ).
