The Problem
Bearing on the motor was failing prematurely in certain vehicle locations. There was uncertainty as to whether temperature was a contributory factor (this was the element SET
was asked to investigate)
Challenges for SET
- Installing under-vehicle data-logging equipment
- Installing temperature sensors to multiple locations without mechanical fixings allowed
Solution
- Custom sensors produced for each location, and installation method developed to allow on-vehicle installation process
- Data logger enclosure with high impact resistance and additional robustness added by modifying underframe bay door
- Exhaust silencer eliminated as contributory factor (an early theory based on proximity of exhaust to bearing cover)
- Inadvertent heating of motor air intake identifi ed as an issue
