Key Components and Functionality
1. Air Spring Basics:
Uses compressed air within a flexible bellows to provide adjustable support, damping, and load-bearing capabilities. Common in vehicles (trucks, buses, trains) and industrial machinery.
2. Flange Connection:
Design: Features a protruding rim (flange) at one or both ends, typically with bolt holes for secure mounting. The flange ensures alignment and distributes stress evenly.
Sealing: Often includes gaskets, O-rings, or sealed grooves to maintain airtightness, critical for pressure retention.
Materials: Flanges are usually made of durable metals (steel, aluminum) to withstand high pressure, vibration, and environmental stressors.
