Abstract
A power steering system for transferring torque to a sector gear includes a first ball screw and a first ball nut circumscribing the first ball screw. The first ball nut is in torque-transfer communication with the first ball screw through a plurality of ball bearings and is meshed or engaged with the sector gear for torque transfer therewith. An electric motor is configured to selectively supply torque to the sector gear through the first ball nut.
