Abstract
A Coriolis gyro having an arrangement which comprises a substrate, at least two individual structures and spring elements. The spring elements couple the individual structures to the substrate and to one another. Force transmitters and taps are provided. The arrangement has at least one excitation mode which can be excited by the force transmitters and at least one detection mode which can be measured by the taps. The excitation mode and the detection mode are closed, as a result of which no disturbance excitations of the excitation mode and of the detection mode can be caused by linear accelerations and/or vibrations if there is no need to take account of manufacturing tolerances.

23. A Coriolis gyro having an arrangement which comprises a substrate, at least four individual structures and spring elements, wherein the spring elements couple the individual structures to the substrate and to one another, having force transmitters and having taps, wherein the arrangement has at least one excitation mode which can be excited by the force transmitters and at least one detection mode which can be measured by the taps, wherein the detection mode can be excited, in the excited excitation mode, on the basis of a Coriolis force when the Coriolis gyro is rotated about a sensitive axis, wherein the excitation mode comprises two antiphase-coupled linear oscillations, which are once again in antiphase, of in each case two of the individual structures;
-
characterized in that the detection mode comprises a mixed form of two coupled, antiphase rotary oscillations and two antiphase linear oscillations, which are once again in antiphase, of in each case two of the individual structures, with the excitation mode and the detection mode being closed eigenmodes of the arrangement, by means of which theoretically, that is to say if manufactured optimally without any manufacturing tolerances, no forces or moments can be extended on the surrounding area of the Coriolis gyro. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
