Abstract
In some examples, a device configured to determine an estimated remaining use of a brake assembly includes a magnet configured to move in response to movement of a wear pin indicator of the brake assembly, a sensor configured to generate an output signal based on a position of the magnet relative to the sensor, and processing circuitry configured to determine the estimated remaining use of the brake assembly based on the output signal generated by the sensor.
Claims20
A device configured to determine an estimated remaining use of a brake assembly, the device comprising:
- a magnet configured to move in response to movement of a wear pin indicator of the brake assembly, wherein a position of the magnet corresponds to a remaining wear length of the wear pin indicator, and wherein the remaining wear length decreases with use of the brake assembly;
- a sensor configured to generate an output signal based on the position of the magnet relative to the sensor;
- and
- processing circuitry configured to determine the estimated remaining use of the brake assembly based on the output signal generated by the sensor.
A method of determining an estimated remaining use of a brake assembly, the method comprising:
- receiving an output signal generated by a sensor based on a position of a magnet relative to the sensor, wherein the magnet is configured to move in response to movement of a wear pin indicator of the brake assembly, wherein a position of the magnet corresponds to a remaining wear length of the wear pin indicator, and wherein the remaining wear length decreases with use of the brake assembly;
- and
- determining an estimated remaining use of the brake assembly based on the output signal generated by the sensor.
A device configured to determine an estimated remaining use of a brake assembly, the device comprising:
- a spring configured to expand or compress in response to movement of a wear pin indicator of the brake assembly;
- a mounting element coupled to an end of the spring and configured to move laterally in response to the movement of the wear pin indicator, wherein the mounting element is configured to move in a same direction as the movement of the wear pin indicator;
- a magnet coupled to the mounting element, wherein a position of the magnet corresponds to a remaining wear length of the wear pin indicator, and wherein the remaining wear length decreases with use of the brake assembly, and wherein the remaining wear length of the wear pin indicator corresponds to the estimated remaining use of the brake assembly;
- a sensor configured to generate an output signal based on the position of the magnet relative to the sensor;
- and
- processing circuitry configured to determine the estimated remaining use of the brake assembly based on the output signal generated by the sensor.
