An apparatus for measuring relative displacement between a first shaft and a second shaft includes first and second rotor assemblies. The first rotor assembly is coupled to the first shaft and is centered on an axis. The second rotor assembly is coupled to the second shaft. The second rotor assembly has first and second stator plates. Each of the first and second stator plates includes an upper surface and a lower surface. The upper and lower surfaces are parallel. The first and second stator plates include a plurality of teeth extending in a direction radial of the axis. The first and second stator plates form a gap between the lower surface of the first stator plate and the upper surface of the second stator plate. The apparatus further includes at least one magnet having a magnetic field and disposed on the first rotor assembly and a sensing device disposed within the gap for sensing a magnetic flux of the magnetic field.

An integrated torque and position sensor is set forth for measuring the relative rotational movement between an input and an output shaft and for measuring the final angle position of the output shaft. The integrated sensor includes a wheel that rotates with the shaft. An incremental sensing mechanism detects the incremental rotation of the shaft. In response to the shaft rotating to a predetermined angle, an actuation mechanism engages the wheel with a change gear for every new revolution in which the shaft passes. A segment sensing mechanism detects the segment in which the shaft is disposed. A method is set forth to calibrate and compensate the electrical outputs generated by the integrated torque and position sensor. The method produces common amplitudes and establishes a common angle with an expected phase angle shift for the electrical outputs. The compensated electrical outputs are inserted into a solver equation and the values generated by the solver equation are inserted into an algorithm to calculate the final angle position of the shaft.

A rack-and-pinion steering gear is provided. The gear comprises a lower shaft, a pinion gear, a first bearing, and a plurality of stakes. The lower shaft has a first end, a second end, and a shoulder depending radially outward from the lower shaft. The pinion gear is defined in a portion of the lower shaft proximate the first end. The first bearing has a first side, a second side, and an inner edge. The inner edge is disposed on the lower shaft such that the first side abuts the shoulder. The stakes have a first section that conforms to a radius defined at an intersection of the second side and the inner edge of the first bearing, and a second section resting against the second side of the first bearing.
