Claim 2:
3. The micromechanical rate-of-rotation sensor set-up as recited in claim 1, wherein the second rate-of-rotation sensor device capable of being driven linearly includes:
a frame device having a first frame and a second frame;
the second frame being at least partially surrounded by the first frame;
the first frame being able to be driven along the third axis in an oscillatory manner, and the second frame being able to be driven along the third axis in an oscillatory manner, in phase opposition to the first frame;
due to the third outer rate of rotation about the first axis, the first and second frames being able to be deflected in phase opposition along the second axis, in an oscillatory manner;
the first frame includes a first subframe and a second subframe, and the second frame including a third subframe and a fourth subframe;
a third coupling device, by which the first subframe and the third subframe are coupled in such a manner, that in-phase deflection of the first and third subframes along the third axis is suppressed and out-of-phase deflection of the first and third subframe along the third axis is enabled;
a fourth coupling device, by which the second subframe and the fourth subframe are coupled in such a manner, that in-phase deflection of the second and fourth subframes along third axis is suppressed and out-of-phase deflection of the second and fourth subframes along the third axis is enabled; and
a third detection device configured to measure out-of-phase deflection of the first and second frames along the second axis.
