BRAKE MONITORING DEVICE AND COMPONENTS ASSOCIATED THEREWITH

摘要

The present invention refers to a monitoring device for detecting a value indicative of the actuation stroke and/or release stroke of a thrust element (31) of a brake actuating mechanism, the thrust element (31) being actuated by a lever (1;34) of said brake actuating mechanism, comprising a sensor (12; 19; 22; 27; 37) for sensing variations in a physical property of at least one part of said brake actuating mechanism, whereby the sensor (12; 19; 22; 27; 37) and said part of the brake actuating mechanism are arranged so that by the relative movement between said part of the brake actuating mechanism and the sensor (12; 19; 22; 27; 37) repeated variations in said physical property along a path (10; 17; 20; 28; 35) of said relative movement are created and sensed. Said path (10; 17; 20; 28; 35) is formed between the lever (1; 34) and a stationary part being adjacent to said lever (1; 34). The invention is directed both to drum brakes and to disc brakes.
