  • Patent number: 10704637
    Abstract: A bar pin bushing assembly for connecting components including a bar pin having at least one end with at least one bore to receive a fastener, the bar pin having a central portion having a diameter that is greater than a width or diameter of the at least one end of the bar pin, a compressible rubber section having a uniform thickness positioned around the central portion of the bar pin, the compressible rubber section further extending around downwardly tapering surfaces adjacent the central portion of the bar pin, a plurality of outer metal shells mold bonded to the compressible rubber section, wherein when the bushing assembly is inserted into a hub, the plurality of outer metal shells are configured to radially compress the compressible rubber section to provide a precompressed bushing assembly. A method of assembling the bar pin bushing assembly is also disclosed.
