Wheel loss detection

摘要

A device and method for detecting wheel loss from a vehicle when the vehicle is in motion. The device (1) is provided with a housing (11) configured for, in use, mounting the device to a wheel (3) such that the device (1) abuts a wheel hub (5) of an axle to which the wheel is attached. A detector (6) is provided for detecting a proximity of the device (1) to the wheel hub (5), and a transmitter (8) is provided for sending an alarm signal in the event that the detector (6) detects that the device (1) is no longer in proximity to the wheel hub (5). In this way, if the wheel starts to become detached from the wheel hub, the detector (1) detects this and can send an alarm to, for example, a receiver unit in the drivers cabin, allowing the driver to take appropriate steps.

1. A device for detecting wheel loss from a vehicle while the vehicle is in motion, the device comprising:
a housing configured for, in use, mounting the device to a wheel rim of a wheel, such that the device indirectly abuts a wheel hub of an axle to which the wheel is attached, such that the wheel is disposed between the device and the wheel hub, said housing includes a mounting plate comprising an aperture arranged to fit over a wheel hub stud; a detector for detecting a proximity of the device to the wheel rim, and hence indirectly detecting a proximity of the device to the wheel hub; a transmitter for sending an alarm signal in the event that the detector indirectly detects that the device is no longer in proximity to the wheel hub; wherein the device is coupled to a mounting plate comprising an aperture arranged to fit over a wheel hub stud, such that, in use, the device abuts the wheel rim.
