Timbren Industries says the 2007 diesel emission standards and a switch to tapered steel, composite, and air springs in medium and heavy-duty trucks led it to design new Aeon hollow rubber springs and mounting brackets. They are more compact, lighter and more powerful, but still provide gains in ride quality, stability and ease of installation, the company says.
 
Timbren provides suspension solutions for manufactured highway equipment, logging, commercial, emergency vehicle, and OEM applications.

The company makes four different Aeon designs as a supplement to conventional leaf springs, coil springs, torsion bars, or air springs. The empty ride is not affected. The spring is gradually brought into operation according to the load being applied and progressively increases in proportion to the load being carried. Initial take-up is very smooth, Timbren says, and the spring-rate increase is progressive, resulting in an improved ride, improved load handling, greater load stability, and longer spring life.

In logging applications Aeon hollow rubber springs act as vibration isolators.

Timbren says its engineering and design staff will recommend or adapt current designs or develop new rubber spring designs to meet user requirements.
