More Information
Summary:Device for accurate position control of a force-transmitting system comprising at least one solid-state piezo actuator (7), wherein the piezo actuator (7)comprises a metal block (11) which is positioned between end plates (12, 13) and in the direction of the force has at least one duct (14) into each of which a stacked piezo element (15) fits. The height of the block (11) is shorter than the length of the piezo elements (15) and the difference in height corresponds to the shortening of the piezo elements (15) under the maximum permissible axial load acting thereon, and wherein the piezo actuator (7) is incorporated transversely to the direction of force, without play, in such a way into an element of the force-transmitting system that only a force in the axial direction of the ducts (14) can be transmitted to the piezo elements (15).
