Buckling groove for inner tie rod ball joint studs

摘要

The system and method of making an asymmetrical buckling portion in a linkage member that is formed at the same time a hexagonal holding feature is being formed. The presence of the elongated groove drives the force of a buckling event asymmetrically through the inner tie rod ball stud near the area of failure, which influences the tie rod assembly to buckle in the direction of the groove, prior to other components in the linkage system and thus negates the effects of inner tie rod ball stud run-out tolerances that are present in conventional inner tie rod ball studs formed by machining.
