摘要：
A piezoelectric assembly, a method for producing a structural unit with a prestressed piezoelectric actuator and a method for producing a hollow body for prestressing the piezoelectric actuator include an actuator pushed into a spring sleeve and force-lockingly and/or form-lockingly connected under prestress to two ends of the spring sleeve. This provides a structural unit in which the prestressing force of the piezoelectric actuator is permanently fixed by the production process.
