BRAKE DISC STACK WEAR MEASUREMENT

摘要

In some examples, a brake wear measurement system includes an emitter configured to emit a signal and a passive powered sensor system including a controller and a sensor configured to sense the signal emitted by the emitter. The emitter and the sensor of the sensor system are mounted on the brake assembly such as the emitter and the sensor may be configured to move relative to each other as the brake disc stack wears. Thus, a characteristic of the signal emitted by the emitter and sensed by the sensor may change as a function of the brake disc stack wear. The brake wear measurement may further include a processor configured to receive the output generated by the sensor and determine, based on the output, an amount of wear of the brake disc stack assembly.

1. A system comprising:
a brake disc stack; an emitter configured to emit a signal; a sensor configured to sense the emitted signal, generate an output indicative of a characteristic of the sensed signal, wherein the sensor and the emitter are configured to move relative to each other as the brake disk stack wears; and a passively powered controller operatively coupled to the sensor and configured to:
wirelessly receive power from a remote device,receive the output generated by the sensor, and a processor configured to determine an amount of wear of the brake disc stack based on the output generated by the sensor, wherein the controller is configured to transmit, to the remote device, at least one of: information indicative of the output generated by the sensor or the amount of wear of the brake disc stack determined based on the output.
