Title: Inverse piezoelectric actuated clutch
Inventor: JANG GUO-TSAI
IPC: F16D65/18
Filed: 2002-09-20
Granted: 2003-11-21
Abstract: Disclosed is an inverse piezoelectric actuated clutch, comprising a driving element and a driven friction element which one of the driving element and the driven friction element is constituted by piezoelectric elements. The driving element is fix connected with a motor spindle while the driven friction element is fix connected with a driven shaft. When the motor is powered, the driving element rotates synchronously with the output spindle of the motor. If the piezoelectric element is applied with an alternating current power source with a frequency close to the inherent frequency of the piezoelectric element, the piezoelectric element will be subject to the inverse piezoelectric effect and generates a mechanical resonance, so as to separate the contact surface with the driven friction element, thereby unable to drive the driven friction element to rotate the driven shaft. On the other hand, if the driving power source of the piezoelectric elements is cut off, the piezoelectric element cannot generate driving force for the mechanical resonance and the driving element is tightly connected with the driven friction element, enabling the driven shaft to rotate to output torque.
