Patent attributes
A sensor apparatus for a power steering system on a vehicle, where the apparatus includes an input shaft for receiving a steering input and for rotating about a rotational axis. An output shaft is provided for transmitting the steering input from the input shaft to a steered wheel assembly of the vehicle. A torque transmitting member connects between the input shaft and the output shaft for transmitting a torque from the input shaft to the output shaft. A sensor provides an analog output voltage in response to a sensed magnetic field. A magnet is located adjacent and in radially spaced relation to the sensor, and a magnetic field varying member is positioned in a magnetic field of the magnet, where the magnetic field varying member is movable in a longitudinal direction generally parallel to the rotational axis to vary a magnetic flux between the magnet and the sensor in response to relative movement between the input shaft and the output shaft.
