ABSTRACT:
An actuating device for loading a piezoelectric element including a loading element and a control element each fixed, respectively, upon one of a pair of relatively rotatable parts which may form part of a clutch. Cam projections on the control element intermittently lift the loading element away from the piezoelectric element whenever relative rotation of the two rotatable parts occurs in either direction. Sudden release of the loading element after being raised by the cam projections provides loading on the piezoelectric element to produce an electrical discharge thereby, for example, to indicate the occurrence of clutch slippage.
