Abstract: The invention relates to a device for measuring an angle and/or a torque on a rotatable body. The angle of rotation is detected by means of magnetic or optical sensors. In a preferred embodiment, two devices (7, 8) are provided that are provided with two optically readable code traces respectively. The two code traces (1a, 1b or 2a, 2b) of a device (7 or 8) are embodied in the same way and are arranged in such a way that said devices are offset against each other so that allocated sensors (4) output a digital signal. The angle of rotation is calculated from the offset of the two digital signals. In another embodiment, a torsional element (5) having a known torsional stiffness is arranged between the two devices (7, 8). A torque that is transmitted by the rotatable body (3) can thus by calculated from the difference angle of the two devices (7, 8). The inventive device is preferably used in the steering axle of a motor vehicle.

Abstract: A combined torque and angular position detector includes two disks (10, 12) rotatable about a common axis. Relative angular displacement of the disks results from torque applied thereto. Each disk has a number of regions of differing optical transmissivity and these control the transmission of optical radiation from a source (20) to an array (22) on which an image of the regions of the disks is formed. A data processor (24) processes image intensity data and determines the angular positions of the disks and their relative displacement. Alternative arrangements are described in which positional information is derived by (i) providing one disk regions of intermediate transmissivity of width varying around one disk, (ii) by having the regions of lesser transmissivity of width varying around one disk or (iii) by arranging combinations of regions of several different widths around one disk.
