An electromechanical steering system comprises a steering shaft, with a magnetic torque sensor device for measuring a torque applied to the steering shaft and with a shielding element. The steering shaft comprises an input shaft which can be rotationally fixedly connected to a steering handle and penetrates through the shielding element, and an output shaft which is connected to the input shaft via a twistable torsion bar. The torque sensor device comprises a multipole magnetic ring rotationally fixedly connected to the input shaft, a stator ring element rotationally fixedly connected to the output shaft and surrounding the magnetic ring, a magnetic flux collector and a sensor for detecting a magnetic flux density. The shielding element is arranged following the magnetic ring, the shielding element covering the surface of the magnetic ring and the stator ring element with respect to the steering handle.

Steering system comprising a shielded magnetic torque sensor device

A steering system for a motor vehicle having a rotation sensor may include a magnetic element that is attached to a steering shaft and is rotatable with the latter about an axis, two stator elements that are arranged fixed coaxially relative to the steering shaft. The stator elements may be spaced apart axially from one another and may be operatively connected to at least one sensor element via two flux conductors. A flux conductor in each case has a collecting portion, a connecting portion, and a compensator portion. The collecting portion is connected to a stator element and is connected to the compensator portion via a connecting portion. The sensor element may be arranged between the two flux conductors. The compensator portion may have a compensator surface that is smaller than or equal to a collecting surface of the collecting portion.
