Air spring, ASSY

The Air Spring is a standalone, air-filled component designed to be installed separately from the damper (shock absorber).
By adjusting internal air pressure in response to vehicle dynamics and road conditions, it actively controls suspension stiffness and ride height in real-time.

Function

  • Enhanced Ride Comfort: Provides superior vibration isolation compared to metal springs.

  • Adjustable Ride Height: Uses air pressure to maintain a constant vehicle height regardless of load.
  • Improved Driving Stability: Suppresses body roll during cornering and minimizes pitch (fore-and-aft movement) during sudden braking or acceleration.
Features
  • Compressed Air Spring: Uses compressed air as the elastic medium, offering significant weight reduction compared to metal springs.
  • Separated Structure (Easy Maintenance): Features a standalone design where the air spring is separated from the damper (shock absorber).
  • Variable Stiffness: Allows for spring rate adjustment by controlling the internal air pressure.
PyungHwa Advantages
  • We manufacture the bellows—the core component of air struts and air springs—entirely in-house. Our proprietary Axial Ply manufacturing process ensures superior durability and ride comfort.
  • With comprehensive capabilities spanning product design, assembly, process technology, and rigorous performance/durability testing infrastructure, we provide optimized quality solutions tailored to diverse OEM requirements.
