Abstract:
A vibration damper system for a vehicle brake including a vibration detector comprising piezoelectric elements for detecting vibration produced when a rotary member of the wheel brake is braked by a friction member, a control circuit, and a vibrator comprising piezoelectric elements, said vibration detector transmitting a vibration damping a signal based on the detected vibration to said vibrator through said control circuit to suppress vibration, said vibration damper system further comprising a higher voltage source and a plurality of changeover devices provided along a signal line connecting each of said piezoelectric elements of said vibration detector and said vibrator to said control circuit, said control circuit transmitting a changeover signal to at least one of said changeover devices in response to a timing signal inputted into said control circuit to selectively apply high voltage to at least one of said piezoelectric elements from said high voltage source.
