Wheel Loss & Hub Temperature Monitoring

Dynamic monitoring of wheel installation is the best way to prevent wheel loss. Continuous real-time monitoring of any wheel for the potential of a loosening nut is immediately reported to the driver and fleet manager. It is worth noting that a wheel never loosens or detaches from a stationary vehicle! Current solutions rely on a physical inspection and therefore do not address the fundamental problem of a loss of wheel during motion. Wheels are monitored even if the vehicle (e.g. trailer) is unpowered.?In addition monitoring rim temperatures will highlight any potential hub/brake temperature issues.

Wheel Loss Prevention – Reasons wheels come off

• Over torquing/tightening (causes stretching of stud threads)
• Painted or dirty/rusty wheel mating faces
• Training and skill levels on technicians
• Torque wrench calibration
• Incorrect torque setting/failure to re-torque
• Human error
• Lack of wheel and tyre procedures
• Snow chains (fretting of wheels)
• Aged nuts, stud drums and wheels (worn)
• Environmental issues (temperature change/wheel washing)
• Frequent wheel change (increase of risk)
• Inner tyre deflation/blow out
• Kerbing

Wheel Loss Monitoring

None of the current solutions in the market provide an in-motion driver or fleet manager alert for loosening nuts and cannot show accurate rim temperatures and early axle end issues. By including wheel loss sensors to outside wheels an opening for as little as 1mm is detected showing the early signs of potential wheel loss. Alerts are immediately transmitted to the driver together with the added security of immediate alerts also to the fleet manager, immediate action can be taken. Alerts are sent via text or email, together with location and vehicle details.

Utilising a bracket across two wheel nuts (2 per wheel) the sensor regularly transmits rim temperatures and nut movement and will send alerts should temperatures of 100 degrees centigrade be detected. The highest temperature is recorded for an audit trail.

Safety Check After Maintenance

Checks and warnings can be implemented to ensure drivers stop to re-tighten wheels after any maintenance events. Data would be visible to the fleet manager.

Hub/Brake Temperature Monitoring

Monitor temperature to detect hub or brake problems.
