The reversible sleeve air spring has a piston which is an additional component that the convoluted air spring does not have. The piston is the component that is fastened to the moving trailing arm or axle mount and, as a result, plunges in and out of the air cavity within the rubber bellows.
In general, a piston gives the reversible sleeve air spring an advantage over the convoluted air spring in that spring, rates can be further tuned using a variety of piston profiles. For straight-sided pistons, the reversible sleeve air spring has an advantage over the convoluted air spring, in that a constant load for a given internal pressure may be maintained over a range of heights.
A permanent part of the bead plate assembly used to attach the airspring to the suspension.
- Combo Stud
Combination mounting stud and air fitting.
- Bead Plate
Permanently crimped onto the bellows at the factory allowing complete part leak testing prior to shipment.
The heart of an Airide spring. Includes at least four plies, or layers, of material–an inner layer, two plies of cord-reinforced fabric, and an outer layer.
- Bumper (Optional)
A solid molded rubber fail-safe device used on many suspension applications. Prevents
excessive damage to vehicle and suspension in the case of sudden air pressure loss.
The lower section of the 1T and 1X style of airspring made from aluminum, steel or fiber reinforced
plastic. Provides lower mounting arrangement for the airspring in the form of tapped holes or studs.
- Piston Bolt
Attaches the piston to the bellows assembly. Extended, in some cases, to serve as a means of attaching the spring to the suspension.
