Anti-Axle-Wrap Device Schematic - Leaf Spring with Wishbone Upper Link Concept

This document is a simple hand-drawn schematic (appears to be created in a basic paint program) illustrating a concept for an anti-axle-wrap device for a leaf-sprung solid axle, uploaded to the gallery of a 1984 Ford Bronco. The drawing shows a side view of an axle tube (large circle) with a leaf spring passing over it. Instead of the conventional clamped connection between the spring and axle, the design uses a pivot between the leaf spring and axle tube, marked with a red dot. A triangular/wishbone-style upper link extends from a second pivot on top of the axle housing rearward, labeled as being 'similar to that of a 3-link suspension.' The two red dots indicate the pivot points: one at the top of the axle housing for the wishbone upper link, and one at the spring-to-axle interface. The concept allows the leaf spring to locate the axle vertically and laterally while the upper wishbone link resists axle rotation (axle wrap) under torque, since the spring is pivoted rather than rigidly clamped. The document contains no year, model, part numbers, or dimensions, it is purely a conceptual suspension design sketch.
