Camber adjusting means

Claim 1

In an automobile front end suspension system including a chassis forward cross-frame, a lower support arm and a pivot bolt extending from the cross-frame, the pivot bolt extending perpendicular the longitudinal length of the cross-frame and being threaded at the outer end, the inner end of the lower support arm having an opening therethrough, the axis of said opening being perpendicular the longitudinal length of the lower support arm, improved means of adjustably pivotally supporting the lower support arm to the pivot bolt as a means of adjusting the front wheel camber, comprising: a bushing having a cylindrical external surface rotatably received in said opening in the lower support arm, said bushing having a longitudinal opening therethrough, the axis of which is parallel the bushing cylindrical axis, the bushing opening being eccentric to the cylindrical exterior, the bushing receiving said pivot bolt by said longitudinal opening, the length of said bushing measured parallel the cylindrical axis being greater than the thickness of said lower support arm measured parallel the axis of said opening therethrough whereby a portion of said bushing extends exteriorly on both sides of said support arm, and wherein said bushing includes opposed wrench flats on the external cylindrical surface of said portion of said bushing extending exteriorly and rearwardly of said lower support arm, said flats serving as a means of rotatably positioning said bushing on said pivot bolt to thereby longitudinally position said lower support arm, a nut threadably received on said threaded outer end of said pivot nut, said bolt when inwardly threadably advanced serving to directly clamp said bushing against said cross-frame to prevent the rotation thereof; and a tubular bearing interposed between said bushing and said lower support arm opening.
