  • Publication number: 20040232641
    Abstract: The present invention relates to a thrust bushing formed in such a way as to maximize its lubrication during use to minimize its wear. Broadly, at least one surface of the bushing is formed with grooves that extend between its central aperture and its outer diameter to allow the free flow of lubricant between the two and thus lubricate the entire bushing surface of the thrust bushing as it rotates during steering. The grooves may take a variety of forms such as radially extending rectangular grooves or spiral grooves to better spread lubricant over the entire bushing surface. The bushings may be imposed directly between the axle and the lower yoke or may be packaged in a cartridge between a pair of discs to provide a self-contained, well-lubricated package.
