Abstract
An electric power steering assembly includes an electric motor, a gearset, and a ball-screw assembly. The gearset couples the electric motor and a ball nut of the ball-screw assembly such that the electric motor is operable to rotate the ball nut relative to the ball shaft. A plurality of bearings are circulatable through a helical track, which is defined between the ball nut and a ball shaft of the ball-screw assembly, when the ball nut rotates relative to the ball shaft in order to translate the ball shaft relative to the ball nut.
