Why are Air Springs Made of Rubber?
This is the most important role of rubber in air springs. The core
of air springs is to use the elasticity of compressed air, so air
tightness is crucial. Rubber has high elasticity and flexibility,
and can fit tightly on metal parts (such as pistons and end covers)
to form a reliable sealing interface. Even if it is repeatedly
deformed (compressed and stretched) during operation, rubber can
maintain a good sealing effect to prevent high-pressure air
leakage. This is difficult to match with metal or hard plastic.
- Excellent flexibility and elasticity
Air springs need to deform significantly and repeatedly to adapt to
load changes and road impact. Rubber has extremely high elastic
deformation capacity (elongation can reach hundreds or even
thousands of percent), and can easily withstand frequent
compression, stretching and bending deformation. The elastic
modulus of rubber is relatively low and adjustable, which can
provide the required flexibility and effectively absorb and buffer
vibration and impact.
- Excellent fatigue resistance
During vehicle driving, air springs may undergo several or even
dozens of compression/rebound cycles per second. Rubber has
excellent flex fatigue resistance and can maintain performance in
millions or even tens of millions of dynamic deformation cycles
without cracking or failure.
- Good mechanical strength and toughness:
Rubber materials (especially high-performance rubber used for air
springs) have sufficient tensile strength, tear strength and wear
resistance, and can withstand the stress generated by internal air
pressure, installation stress, and external forces such as friction
and scratching that may be encountered during use, ensuring the
durability of the airbag.
- Designability and processability
Rubber formulas can be adjusted according to specific needs (such
as the selection or combination of natural rubber, synthetic rubber
such as chloroprene rubber, butyl rubber, EPDM, etc.) to optimize
its weather resistance (anti-ozone, UV), temperature resistance,
oil resistance, damping characteristics, etc. Rubber can be formed
into complex airbag shapes (such as bladder type, sleeve type,
membrane type) through molding, vulcanization and other processes
to meet the needs of different structural designs.
The rubber material itself has a certain internal friction, which
can absorb part of the energy during the deformation process and
dissipate it as heat energy. This provides the air spring with a
certain inherent damping, which helps to suppress spring resonance
and rapidly decay vibrations. Although the main damping function is
usually undertaken by the shock absorber, the damping of the rubber
airbag itself is also a useful supplement.
Why not Choose Other Materials?
| Metal | Although strong, it lacks the necessary flexibility and sealing,
and cannot achieve the required large deformation and dynamic
sealing. |
| Hard plastic | The flexibility, elasticity and sealing are usually not as good as
rubber, the fatigue resistance is poor, and it is easy to become
brittle and crack under repeated deformation |
| Fabric | It is not sealed by itself and requires a coating (usually also
rubber-based), but pure fabric cannot provide reliable
airtightness. |
