<p>The device described comprises a torsion element in the form of a spoked wheel (11). Every second spoke (28) is separated from the rim (23) of the wheel (11) and connected to a slotted disc (15). Another slotted disc (14) is coupled to the rim (23) of the spoked wheel (11). When the spokes (26) which function as flexion bars are bent, the two slotted discs (14, 15) are twisted with respect to each other. As a result, the impedance in a coil (16) carrying a high-frequency alternating current is modified in accordance with the eddy current principle. The measurement signal so produced is a function of the torque induced. The application of the measuring device is particularly advantageous in motor vehicles with power-assisted steering.</p> |
