  • Directional bushing
    Patent number: 7762758
    Abstract: A directional bushing is provided for a pinned joint of an articulated structure such as a front end loader used with a work vehicle. The bushing has an annular ring portion and an oblong flange portion. The flange portion extends angularly outward from one side of the ring portion so as to form a wider rounded end. The flange portion is thicker at the area adjacent to the ring portion so as to provide additional support to the ring portion under load, and tapers to a more thin profile at the rounded end. The bushing is surface welded to the structure at the pinned joint with the flange portion oriented in the direction of the greatest load when the structure is articulated, so that the load is more evenly distributed over a wider area, thereby preventing weld failure.
