An air spring ( ) for use in a motor vehicle suspension system is provided. The air spring includes a generally cylindrical flexible bladder ( ) having a circular upper opening ( ), a support unit ( ) sealingly connected to the flexible bladder ( ), and a unitary integrated top assembly ( ) connected to the upper opening ( ) in an air-tight manner. The support unit ( ) further includes an installation fastener ( ) for connection to vehicle support brackets ( ). The top assembly ( ) includes a sealed body ( ) having an interior open volume ( ) and optional attachment components positioned on the body to connect the top assembly to a vehicle main frame. The top assembly further includes an optional connection port ( ) adapted for pneumatic intercommunication with other air springs and an optional fill port ( ) for connection to a pressurized air system.

Integrated air spring

An integral one-piece end plate and bracket combination is formed of a high strength plastic and is mounted in an airtight sealing engagement with an open end of a flexible elastomeric sleeve which forms the fluid pressure chamber of an air spring. The end plate includes a semi-circular wall which extends perpendicular to a longitudinal axis of the air spring and a semi-circular opening. The bracket includes an upstanding wall perpendicular to the semi-circular wall of the end plate and a half dome-shaped wall, which together with the upstanding wall, forms an auxiliary fluid chamber which is in fluid communication through the semi-circular opening with the main fluid chamber of the flexible sleeve. The upstanding wall includes attachments for securing the bracket and end plate to a support structure which aligns with a longitudinal axis of the air spring. A fluid inlet conduit extends outwardly from the upstanding bracket wall to provide fluid communication between the auxiliary fluid chamber of the bracket and an external source of pressurized fluid. A plurality of reinforcing ribs are formed on the walls of the bracket and on the end plate to provide a rigid structure.
