ABSTRACT:
A member of a vehicle steering gear moves longitudinally to effect steering movement of steerable wheels of a vehicle. A bearing is fixed in a housing and supports the member for the longitudinal movement. The bearing includes an electric coil for, when energized, generating lines of magnetic flux. A brass sleeve is fixed to the member and moves in opposite axial directions from a neutral position to change the reluctance of the path for the lines of magnetic flux and to provide a different reluctance at different positions of the brass sleeve relative to the bearing. The reluctance of the path decreases when the brass sleeve moves in one axial direction from the neutral position and increases when the brass sleeve moves in the other axial direction from the neutral position. A signal associated with the reluctance of the magnetic path is sensed to thereby provide a signal indicative of the position of the member.
