Embodiment Construction

[0048] exist figure 1 with 2 Submodule 21 is shown in , where figure 1 show the internal structure and figure 2 Shows the external view. Inside the submodule 21 , in the embodiment shown here, five piezoelectric actuators 1 are arranged in a row. The internal electrodes (not shown) of each polarity of the piezoelectric actuator are connected in parallel through the external electrodes 1b. The piezoelectric actuators 1 are all multilayer actuators.

[0049] A flexible board 2 with conductor tracks 2b is soldered to an external electrode 1b of one polarity in each case. In this case, each external electrode 1 b of each piezoelectric actuator 1 is assigned a conductor track 2 b on the flexible board 2 . The solder connections (through-holes with through-hole plating) for the electrical connection of the external electrodes 1 b to the conductor tracks 2 b are marked with the reference numeral 3 . The solder connection for the mechanical connection of the external electrode...

Abstract

The invention relates to a force module (20) for generating forces in a highly dynamic manner by assembling a plurality of piezo actuators (1) for connecting to a voltage source. To enable the force module (20) to generate forces in the range of a few 100 kN in a highly dynamic and spatially resolved manner, according to the invention it is proposed that the force module (20) consists of at least two sub-modules (21), each having at least two piezo actuators (1) and their electrical contacting elements, and a controlling and protection module (16) for the piezo actuators (1) in the sub-modules (21), wherein all electric contacting elements of the sub-modules (21) are fed into the controlling and protection module (16).

Description

technical field [0001] The invention relates to a force module for generating a force in a highly dynamic manner by combining a plurality of piezoelectric actuators for connection to a voltage source and to the use of the force module. Background technique [0002] The current state of the art for generating forces in a highly dynamic manner is piezoelectric low-voltage actuators as piezoelectric actuators, which are constructed in a multilayer structure. The working capacity and thus also the force capacity are essentially determined by the volume of the piezoelectric actuator, for which process-dependent limits are established. Typically generateable forces are of the order of only a few kN. [0003] Although higher forces are achieved when known high-voltage actuators are used as piezoelectric actuators, spatial resolution is thus not possible because of the configuration of the high-voltage actuators formed by discrete piezoelectric disks. Can be constructed substantia...
