A method of manufacturing a torsion bar includes cutting a stock torsion bar material to a desired torsion bar length to form the torsion bar. The method also includes forming a first end portion by removing material from the torsion bar to form a first annular groove extending circumferentially about the torsion bar. The method further includes forming a second end portion by removing material from the torsion bar to form a second annular groove extending circumferentially about the torsion bar.

Torsion bar active length control and method of manufacturing

An electric power steering assembly includes a rotor assembly that is rotatable about a longitudinal axis. The rotor assembly has an outer surface and an inner surface. The rotor assembly defines a plurality of magnet pockets that are disposed proximate the outer surface. The inner surface defines a plurality of rotor teeth.

Electric power steering assembly

A torsion bar includes a central portion extending in an axial direction about a longitudinal axis. The torsion bar also includes a first end portion having a splined outer surface, the first end portion disposed proximate a first end of the torsion bar, the first end portion spaced from the central portion with a first annular groove extending circumferentially about the torsion bar.

A method of assembling an electric power steering assembly includes providing a shaft that extends along a longitudinal axis between a first shaft end and a second shaft end. The method further includes extruding or drawing the shaft through a die to define a spline that extends between the first shaft end and the second shaft end. The spline includes a first tooth having a first tip. The method still further includes applying a sleeve over a portion of the spline, such that the sleeve extends from the second shaft end towards the first shaft end.

A steering system includes a tie rod and an actuator assembly. The tie rod is movably disposed within a tie rod housing. The actuator assembly includes a first member and a second member. The first member extends from an actuator. The second member has a second member first end operatively connected to the first member and a second member second end operatively connected to the tie rod. The second member first end is arranged to translate the tie rod along a first axis responsive to the actuator moving the second member first end relative to a second axis.
