Abstract:
A micromechanical yaw rate sensor, comprising:a substrate; a bridge; an anchoring device provided on the substrate and including two opposite bases that are connected fixedly with the substrate and that are connected with one another via the bridge; a flexural spring device; and an annular flywheel that is connected via the flexural spring device with the anchoring device such that an area of connection with the anchoring device is located essentially in a center of a ring of the flexural spring device, so that the annular flywheel is displaceable, elastically from a rest position, about an axis of rotation situated perpendicular to a surface of the substrate, and about at least one axis of rotation situated parallel to the surface of the substrate, wherein: at least one V-shaped flexural spring of the flexural spring device is attached to each of opposite sides of the bridge in such a way that an apex is situated on the bridge and limbs of the V-shaped flexural spring are spread towards the annular flywheel with an opening angle other than 90 degrees.
