Abstract
In some examples, device is configured to determine an estimated remaining use of a brake assembly. The device includes a transceiver configured to transmit a signal towards a wear pin in the brake assembly at a first time. The transceiver is also configured to receive a reflection of the signal from the wear pin at a second time. The device further includes processing circuitry configured to determine a difference of the first time and the second time. The processing circuitry is also configured to determine the estimated remaining use of the brake assembly based on the difference of the first time and the second time.
Claims20
A device configured to determine an estimated remaining use of a brake assembly, the device comprising:
- an attachment element configured to attach the device to a brake carrier of the brake assembly without the device contacting a wear pin in the brake assembly;
- a transceiver configured to:
- transmit a signal towards the wear pin at a first time, wherein the wear pin moves relative to the brake carrier as a brake lining of the brake assembly wears down over time;
- and
- receive a reflection of the signal from the wear pin at a second time;
- and
- processing circuitry configured to:
- determine a difference of the first time and the second time;
- and
- determine the estimated remaining use of the brake assembly based on the difference of the first time and the second time.
A method comprising:
- causing a transceiver attached to a brake carrier of a brake assembly without the transceiver contacting a wear pin in the brake assembly to transmit a signal towards the wear pin in the brake assembly at a first time, wherein the wear pin moves relative to the brake carrier as a brake lining of the brake assembly wears down over time;
- causing the transceiver to receive a reflection of the signal from the wear pin at a second time;
- determining a difference of the first time and the second time;
- and
- determining an estimated remaining use of a brake assembly based on the difference of the first time and the second time.
A device configured to determine a rate of wear for a brake assembly, the device comprising:
- a transceiver configured to:
- transmit a first signal towards a wear pin in the brake assembly at a first time;
- receive a first reflection of the first signal from the wear pin at a second time;
- transmit a second signal towards the wear pin at a third time;
- and
- receive a second reflection of the second signal from the wear pin at a fourth time;
- and
- processing circuitry configured to:
- determine a first estimated remaining use of the brake assembly based on a difference of the first time and the second time;
- determine a second estimated remaining use of the brake assembly based on a difference of the third time and the fourth time;
- determine a number of braking events between the first time and the third time;
- and
- determine the rate of wear based on the first estimated remaining use of the brake assembly, the second estimated remaining use of the brake assembly, and the number of braking events.
