| 摘要 |
The invention refers to a brake monitoring device for sensing a value which reflects the actuation stroke and/or the release stroke of a thrust element (8) of a brake actuating mechanism (4), which thrust element (8) is guided in a housing of a brake caliper (1), wherein the thrust element (8) acts via a brake lining (3) onto a brake disc and is actuated by a lever (5), comprising a sensor (11) which is configured to detect variations of a physical quantity at at least one component of the brake actuating mechanism (4), wherein the sensor (11) and the component are arranged such that due to a relative movement between the sensor (11) and the component constantly repeating variations of the physical quantity along a path (B) are generated and detected, wherein the path (B) is formed between the component of the thrust element (8) and the sensor (11) in axial direction of the thrust element (8), and wherein said path (B) is formed by means of a linear extension (9;15;20) which extends from the end of the thrust element (8) facing the brake disc, axially away from the brake disc. |
