Angle body of revolution and/or angular velocity and/or device null body of revolution the torque operation to this body of revolution

摘要

(57) According to the invention summary, an apparatus for measuring torque and / or angle in the rotating body is provided. In this device, the rotation angle is detected using an optical sensor or magnetic. Especially, in an advantageous embodiment, two units having optical scanning code channels each two (7, 8) are provided. Code channels of both units (7 to 8) of the (1a, 1b not to 2a, 2b) is constructed in the same way and are arranged offset from one another. This sensor, assigned (4) to transmit a digital one signal. The deviation of the two digital signals, the rotation angle is calculated. In another embodiment, between two units (7, 8), members (5) is adapted to be arranged with torsional rigidity torsional known. Therefore, it is possible from the angle difference between the units 7 and 8 of two, and also calculates the torque transmitted from the rotating body (3). The device is used in a steering shaft of an automobile advantageously.
