What is an Air Spring?
In simple terms, an air spring is an inflatable rubber bladder. It
uses the elasticity of compressed air within a confined space to
support loads and absorb shock and vibration. Its operating
principle is similar to that of a car tire, but its design and
purpose are completely different.
Basic Structure: It typically consists of an air bladder made of
high-quality rubber (such as natural rubber) (reinforced with one
or more layers of cord) and upper and lower metal cover plates
(usually pressure plates).
How it works: By injecting compressed air, the internal pressure
increases, generating support force and elastic deformation. The
higher the pressure, the greater the load capacity and stiffness.
Why Choose "Rubber"?
Main material: Typically made of high-strength, highly elastic
natural rubber.
Reinforcement: Multiple layers of high-strength cord (such as
nylon, polyester, or aramid) are sandwiched within the rubber. This
layer is crucial for bearing pressure, similar to the structure of
a tire, preventing the airbag from inflating indefinitely,
deforming, or even exploding.
Features:
Excellent flexibility and fatigue life: Capable of withstanding
high-speed reciprocating compression and deformation hundreds of
times per minute.
Excellent airtightness: Ensures compressed air leaks and stable
pressure.
Oil resistance: The rubber formula must be oil-resistant in
environments where lubricants may be present.
Aging resistance: Able to withstand long-term operation under
certain temperature and environmental conditions.
Selection and Maintenance Key Points
Selection Parameters:
Installation Space and Stroke: Determine the available installation
height, compressed height, and required stroke.
Operating Pressure: Select based on the required load capacity and
the manufacturer's recommended pressure range.
Interface Size: The thread size of the air inlet.
Common Faults:
Rupture of the Rubber Bladder: Usually caused by overcompression,
overinflation, aging, or scratches from sharp objects.
Air Leakage: Damage to the bladder or failure of the seals at the
upper/lower metal pressure plates.
Daily Maintenance:
Regularly inspect the surface for cracks, scratches, or bulges.
Ensure use within the specified pressure and stroke range.
Keep the air source dry and clean to prevent moisture and
impurities from entering the bladder, which can accelerate aging.
