WEAR MONITORING DEVICE, EXPANSION MODULE FOR A WEAR MONITORING DEVICE, AND DISC BRAKE HAVING A WEAR MONITORING DEVICE OF THIS TYPE OR HAVING AN EXPANSION MODULE OF THIS TYPE

摘要

The invention relates to a wear monitoring device for a disc brake which has a brake disc, a first brake lining on a first side of the brake disc, and a second brake lining on a second side of the brake disc, in particular for utility vehicles. The wear monitoring device has: a first sensor device (22), which quantitatively senses the cumulative wear of the first and second brake linings and emits a first electrical output signal, associated with the cumulative wear, at the output terminal thereof; an evaluation device (28); and a signal line (26), which is connected on one side to the output terminal of the first sensor device and on the other side to the evaluation device. The signal line is arranged such that it meets a stop when a predefined first wear limit of the first or second brake lining is reached.
