ABSTRACT:
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.
