| 摘要 |
The invention relates to a piezoactuator ( 1 ) comprising a piezoelectric body ( 4 ) and elements for pre-tensioning the piezoelectric body, consisting of a first ( 2 ) and a second ( 3 ) connecting element for transferring forces to the piezoelectric body ( 4 ). The actuator is provided with an element ( 6 ) for transferring tensile/pressure forces between the connecting elements ( 2, 3 ), said element being at least partially located in a gap ( 5 ) in the form of a bore in the piezoelectric body ( 4 ). According to the invention, the piezoactuator ( 1 ) is set to a defined working curve using the pre-tensioning elements ( 2, 3, 6 ). The piezoelectric body ( 4 ) is preferably produced by the lamination of piezoelectric layers, into which a gap is drilled after lamination and the component is subsequently sintered. |
