A gear mechanism usable in an electric power steering system is provided. The gear mechanism includes a gear housing including a passage formed therein, a gear positioned in the passage, and a signal transmission medium positioned in the passage adjacent the gear. A partition is inserted into the passage to prevent contact between the signal transmission medium and the gear.

A vehicle power steering assembly is provided. The vehicle power steering assembly includes an input shaft having first and second end portions that extend along an axis, and a first aperture that extends substantially axially into the first end portion. The vehicle power steering assembly further includes a torsion shaft having third and fourth end portions. The third end portion has a first plurality of splines and the fourth end portion has a second plurality of splines. The third end portion is disposed in the first aperture of the input shaft. The first plurality of splines on the third end portion fixedly couples the torsion shaft to the input shaft. The vehicle power steering assembly further includes an output shaft having fifth and sixth end portions, and a second aperture that extends substantially axially into the fifth end portion toward the sixth end portion. The fourth end portion of the torsion shaft is disposed in the second aperture of the output shaft. The second plurality of splines on the fourth end portion fixedly couples the torsion shaft to the output shaft. A rotational movement of the input shaft a predetermined distance in a first direction about the axis induces rotational movement of the output shaft in the first direction.

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.
