Embodiment Construction

[0018] refer to figure 1 with 1A , a remote sensing system for an air spring 100 (also known as a gas spring) is shown generally at 10 . The sensing system 10 includes one or more wireless sensors 14 embedded in an elastomeric spring wall 102 (also known as a bellows or flex sleeve) of the air spring 100 for sensing various parameters, including but Not limited to temperature, pressure, air pressure, stress, strain, vibration, chemical properties, etc. Sensing system 10 obtains data for monitoring air spring properties or characteristics including, but not limited to, air spring pressure, temperature, elastomeric body integrity, and deflection characteristics. Non-uniformities in the elastomeric spring wall 102, such as bumps and broken plies, may also be monitored and / or discovered.

[0019] Wireless sensors 14 provide sensing data to data collection devices 16 (also referred to as readers or data acquisition circuits) located remotely from the sensors. The data collectio...

Abstract

The present invention relates to a sensor system for obtaining data from an air spring having an elastomeric body in which a plurality of wireless sensors is embedded. The sensor length-scales range from nano-to micro-scale devices that are small enough to avoid becoming occlusions within the elastomeric body. The air spring may include a spring wall having an internally reinforced elastomeric body portion with the sensors embedded within. The air spring may include a spring wall having an unreinforced elastomeric body portion with the sensors embedded within. The sensors may be configured to provide data related to one or more of temperature, pressure, sidewall flex, stress, strain, and other parameters. The sensors may be LCD sensors, and / or conductive polymer sensors, and / or bio-polymer sensors, and / or polymer diodes suitable for sensing data during the operation of the air spring.
