VIBRATION CONTROLLER FOR DISK BRAKE

摘要

PURPOSE: To improve the performance of a vibration controller (performance of preventing a creak) by applying surely vibration to detect brake vibration with a first piezo electric element and damp the brake vibration with a second piezo electric element without being affected by the incorporating accuracy or the like of both piezo electric elements. CONSTITUTION: A first piezo electric element 7 for vibration detecting and a second piezo electric element 8 for vibration applying are in series disposed to be pressed against a pad 3. Thus, a difference between press forces of the first and second piezo electric elements is not generated, so that the vibration is stably detected and applied. Also. the performance is not degraded by that the detection and application of the vibration is performed by one element or the detecting point and vibration applying point are located in different positions respectively.
