Abstract: A device for measuring torque in a rotating shaft of a vehicle steering column including a magnetic-field generator situated in a plane of cross section of the rotating shaft and a detector which delivers a signal proportional to the torque in the rotating shaft as a result of the relative angular offset between the field generator and the detector. A first electronic circuit inside the steering column is fixed to a support that concentrates the magnetic field and moves past the magnetic field generator together with a mechanical connection for angular return of two sections of the rotating shaft. Measurement sensors carried by the first electronic circuit deliver signals to a second electronic circuit outside the steering column, for processing those signals and for operating receiver devices.

Abstract: Two members for generating a magnetic field are fixed symmetrically with respect to a shaft in a first plane perpendicular to the shaft, and two members for detecting the magnetic field are fixed, symmetrically with respect to the shaft, in a second plane which is parallel and axially offset with respect to the first plane. A routing member for routing the magnetic field lines, made of ferromagnetic material, rotationally integral with the shaft and surrounding the shaft, is provided at the periphery of the members for detecting and for generating a magnetic field, on at least that portion of the shaft which lies between the first and second plane.

Abstract: Two magnetic field generators are fixed symmetrically with respect to a shaft in a first plane perpendicular to the shaft, and two magnetic field detector units are fixed symmetrically with respect to the shaft, in a second plane parallel to, and axially offset with respect to, the first plane. The detector units deliver a signal proportional to the torque owing to the relative angular offset of the generators with respect to the detector units such that the plane median to the first plane and second plane passes through the point of maximum deflection of the shaft under a longitudinal flexion force.
