Sensor för beröringsfri avkänning av förslitningen av ett bromsbelägg i ett fordon

The device has a gear mechanism (4) for converting the wear-induced displacement into a rotary movement and a sensor (2) for detecting the rotary movement. A contact-free coupling (3a,3b) is also provided for transmitting the rotary movement to the sensor. The sensor generates an analogue or pulse-width-modulated detection signal, which determines the wear-induced displacement of the brake lining and detection signal, corresponds to the respective displacement caused by the rotary movement. Independent claims are also included for the following: (1) brake for motor vehicle, has a device for measurement of wear caused by adjustment of a brake lining (2) motor vehicle (3) method for the measurement of wear caused by adjustment of brake lining opposite to an associated brake caliper, involves detecting corresponding signal to the respective adjustment caused by the rotating motion.
