Abstract
Abstract The adjuster tube, threaded at opposite ends to an outer tie rod and an inner tie rod in a steering linkage, is provided at one end with anti-rotational means on the exterior thereof including a radial inward extending aperture means and the tie rod at this end has longitudinally extending splined grooves formed on a portion of the threaded end thereof engaged with the adjuster tube. The adjuster retainer is provided with protruding tabs at one end thereof to engage the splines in the tie rod, and is provided at its other end with means to engage the anti-rotational means of the adjuster tube.

Claim 4
Dependent Claim
247 words
An adjustable tie rod assembly comprising a tubular sleeve internally threaded at opposite ends, said sleeve having an anti-rotation means thereon including at least a radial extending aperture means adjacent one end thereof, a first tie rod threaded at one end, adjustably received in one end of said sleeve in threaded engagement therewith, a second tie rod, threaded at one end, adjustably received in the opposite end of said sleeve in threaded engagement therewith, said first tie rod having a plurality of axially extending spaced apart spline grooves thereon adjacent said one end, and a retainer means having means at one end thereof engaging said anti-rotation means of said sleeve to prevent rotation of said retainer means relative to said sleeve and having spline engaging tab means at its other end engaging at least one of said spline grooves of said first tie rod to lock said first tie rod against rotation relative to said sleeve, said retainer means including a semi-circular curved flange extending axially along said sleeve for abutment with the outer periphery of said sleeve, said curved flange having an aperture therethrough, a fastener extending through said aperture in said flange into threaded engagement with said aperture means in said sleeve, said retainer means further including a radial inward extending flange integral with one end of said curved flange, said radial flange having at least one retaining tab at the free end thereof engaging one of said spline grooves in said first tie rod.
Claim 5
Dependent Claim
278 words
An adjuster tie rod assembly comprising a tubular adjuster sleeve provided with opposite hand internal threads at opposite ends thereof, the outer peripheral surface of said tubular adjuster sleeve being provided with a flat adjacent to one end of said adjuster sleeve with a radially inward groove extending longitudinally of said flat surface, a first tie rod threaded at one end adjustably received in said one end of said adjuster sleeve in threaded engagement therewith, a second tie rod threaded at one end adjustably received in threaded engagement at the opposite end of said adjuster sleeve, said first tie rod having splined groove means thereon adjacent said one end, and a U-shaped spring adjuster retainer, said adjuster retainer having a first arm and a second arm with an interconnecting web therebetween, the free ends of said first arm and said second arm being normally resiliently biased away from each other, said first arm having an oblong hole therethrough of a nominal size to slidably encircle said one end of said first tie rod, said oblong hole providing an inner peripheral edge with radially inward extending tab means thereon of a configuration complementary to said groove means whereby said tab means when in alignment with said groove means can project into said groove means, said second arm having a substantially circular aperture therethrough defining at a segment thereof a flat edge with a tab projecting radially inward toward the center of said aperture, the nominal diameter of said aperture being such whereby said one end of said tubular sleeve with said flat thereon can be slidably received in said second arm and engaged therewith to prevent rotation relative thereto.
