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.
