Abstract
An apparatus for use in turning steerable vehicle wheels includes a steering member connected to at least one steerable vehicle wheel. The steering member moves axially to effect turning movement of the at least one steerable vehicle wheel. The steering member has an externally threaded portion. A ball nut assembly is connected with the externally threaded portion of the steering member. The ball nut assembly is rotatable relative to the steering member to axially move the steering member. A first gear member is rotatable in response to rotation of a steering wheel. A second gear member disposed in meshing engagement with the first gear member rotates in response to rotation of the first gear member. The ball nut assembly rotates relative to the steering member in response to rotation of the second gear member.
