Anatomy of an Aeon® hollow rubber spring – Part 1

Rusty Aeon

One of the staff at Timbren Industries found it lying on the side of the road just outside our manufacturing facility in Whitby, Ontario, Canada.

As you can see, the truck frame is completely rusted and flattened. But the rubber spring is still good!

If you have ever wondered how Aeon® rubber springs work, perhaps you need a crash course in rubber spring technology.

Why don’t we take a look at the unique characteristics and qualities of Aeon® spring helpers?

Built into every Aeon® rubber spring are some unique characteristics:

  1. Progressive Spring Rate

Aeon® rubber springs automatically adjust to the load. When the load increases, the rubber spring dramatically increases in spring rate.

That’s because as the Aeon® spring begins to deflect, the rubber gets progressively denser. Instead of deflecting in a linear fashion (like a metal spring), an Aeon® spring holds the weight with very little deflection.

The result is extra stability, no sagging and a vehicle that remains level under load.

  1. Self-Damping Properties

Aeon® rubber springs are able to reduce shock and vibration. That’s because of a little thing called “hysteresis.”

In other words, Aeon® rubber springs have the ability to absorb the energy that extra weight produces. The absorption effect is the same as that of a shock absorber. The result is a smooth ride.

  1. Vibration Isolation

Due to their ability to reduce the transfer of energy, Aeon® rubber springs dampen shock and vibration. The result for a truck suspension is a quiet ride and greater control.

Doesn’t this give you some idea why an Aeon® rubber spring would outlast and outperform a rusty, old frame?

We’ve been saying it for over 40 years, and we still think it’s true:  Aeon® springs are “stronger than steel, more reliable than air.”
