Abstract: A torsion bar for a vehicle steering system includes a first end region. The torsion bar also includes a second end region. The torsion bar further includes a main body extending about a longitudinal axis of the torsion bar from the first end region to the second end region, wherein the main body defines a plurality of splines circumferentially spaced from each other to form a splined outer surface extending along the entire length of the main body.

Abstract: A power steering system includes a rack housing arranged to receive a longitudinally displaceable rack member. The system also includes an assist cover connected to the rack housing, the rack housing and the assist cover defining a cavity. The system further includes an assist assembly at least partially disposed within the cavity. The assist assembly includes a power pack connected to at least one of the rack housing and the assist cover, the power pack having a power pack shaft extending therefrom. The assist assembly also includes a drive pulley having a drive pulley shaft that extends between the rack housing and the assist cover, the drive pulley shaft and the power pack shaft separate shafts and operatively coupled to each other. The assist assembly further includes a driven pulley disposed about the rack member.

Abstract: A method of manufacturing a torsion bar for a steering system is provided. The method includes supporting a torsion bar blank on a cold forming machine with a plurality of dies at a first end region of the torsion bar blank and a second end region of the torsion bar blank. The method also includes rolling the torsion bar blank to form an end region having a cylindrical outer surface extending from an axial end surface and a serrated portion disposed proximate the end region and axially offset from the axial end surface.
