Abstract: A first shaft and a second shaft are connected coaxially. A torsion bar converts a torque applied between two shafts into a torsion displacement. A multipolar magnet is fixed to the first shaft. One set of magnetic yokes is fixed to the second shaft and disposed in a magnetic field generated by the multipolar magnet. The magnetic yokes are opposed to each other via an air gap in an axial direction. A magnetic sensor is provided for detecting the density of magnetic flux generated in the air gap. A non-magnetic spacer is disposed between the magnetic yokes as a means for positioning the magnetic yokes. The spacer and the magnetic yokes are integrated by resin molding.

This device detects the angle of rotation of a rotary member with the output signals from the magnetic sensors. In the target of the spur gear shape, moreover, the two circumferential end portions of the crests of all the teeth are formed into angular portions.

Abstract: A driving control unit (21b) of a controller (21) determines which of an input shaft (32) and an output shaft (33) in a steering shaft (3) is dynamically superior and when the output shaft (33) is dynamically superior to the input shaft (32), a motor (6) is driven so that torque resulting in a time integral value smaller than a time integral value of relative torque between the input shaft (32) and the output shaft (33) is generated in a backward assist direction.

Abstract: The present invention is an apparatus for obtaining an indication of torque, axial alignment and axial location for a shaft rotating about an axis of rotation. A first set of detectable elements are operably connected to the shaft and positioned parallel to the axis of rotation. A second set of detectable elements parallel to the axis of rotation are interlaced in a sensing plane with said first set of detectable elements. The second set of detectable elements have a variable relative position with respect to the first set of detectable elements. A third set of detectable elements are positioned laterally to the first set of detectable elements and the second set of detectable elements in an alignment plane parallel to the sensing plane. The third set of detectable elements are positioned at an offset angle to the axis of rotation.

Abstract: A torque sensing device adapted for use in an electric power assisted steering system is provided. In one embodiment, the device comprises first and second shafts interconnected by a torsion bar, a bushing disposed about the torsion bar and frictionally engaged with one of the shafts, and a stator/sensing device assembly. One of the shafts defines a projection while the other shaft defines a recess. The recess receives the projection and allows a limited degree or rotational movement of the projection within the recess. A plurality of magnets is disposed circumferentially about bushing. As a result of the frictional engagement with one of the shafts, the bushing rotates independently of the stator assembly. A sensing device, such as a Hall effect sensor, is positioned within a clearance between first and second poles within the stator and detects relative rotation of the bushing, which is indicative of rotation of the frictionally engaged shaft, within the stator.
