Abstract
A motor vehicle steering system having first and second linkage assemblies, each pivotally coupled to a steerable wheel to exert simultaneous pushes or pulls, depending upon the direction of a vehicle turn. The first linkage assembly has an inboard end which is pivotally coupled to a first T-shaped track-inducing member which is connected to the steering box of the vehicle. The second linkage assembly is connected to a second T-shaped track-inducing member. Ends of the track-inducing members opposite to the linkage assemblies are joined by an arm. Rotation of a vehicle steering wheel causes the first track-inducing member to rotate about a vertical axis defined by the steering box. The joinder of the track-inducing members results in displacements of the inboard ends of the linkage assemblies. Because the connections at the opposed ends of each track-inducing member are out of phase by less than 180.degree., displacements of the linkage assemblies along an axis parallel to the side-to-side extension of the vehicle are dissimilar, and both the first and second steerable wheels track the turn center of the vehicle.
