Rotation rate sensor for measuring rotation rate of rotational motion of rotatable body, has detection device and coriolis element that are connected by spring for coupling deflection in oscillation level to oscillation of detection device

摘要

The sensor (101) has a detection device comprising detection elements (119) that are coupled with one another by a double rocker (121), coupling rockers (121a, 121b) and a coupling beam (123). A drive device is connected with a coriolis element (113) for driving oscillation of the coriolis element. The detection device and the coriolis element are connected by a coupling spring (127) for coupling deflection in an oscillation level of the coriolis element in an orthogonal direction to oscillation of the detection device. The drive device comprises two power units (103) with drive combs (109).
