Abstract
A dual variable-tooth rack and single pinion steering system includes a first elongated rack having an inner end, an outer end, and a set of teeth with a predetermined variable tooth profile located between its ends, a second elongated rack having an inner end, an outer end, and a set of teeth with a predetermined variable tooth profile located between its ends; and a pinion disposed to engage the inner end of the first rack and the inner end of the second rack to thereby define a set of rack displacements between the outer end of the first rack and the outer end of the second rack.
