ABSTRACT:
A power steering apparatus includes an electric motor having an output member which is drivingly connected with a planetary gear set. An output member of the planetary gear set rotates a ball nut. A member which is connected with a steering linkage has an external thread convolution which is engaged by the ball nut. Upon rotation of a steering wheel, the electric motor is energized to drive the planetary gear set. The planetary gear set in turn drives the ball nut to move the drive member which is connected with the steering linkage.
