Bar pin bushing for vehicle suspension

A bar pin bushing assembly for connecting components in a vehicular system, the assembly comprising:

• a bar pin having at least one end with at least one bore to receive a fastener, the at least one bore extending through the at least one end, 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 or tubular outer metal wall, the plurality of outer metal shells are configured to radially compress the compressible rubber section to provide a precompressed bushing assembly;
• wherein each of the plurality of outer metal shells has first and second longitudinal edges that are forced into engagement with the edge of an adjacent outer metal shell when the bushing assembly is inserted into the hub;
• and
• wherein longitudinal voids are positioned in the compressible rubber section between adjacent edges of the outer metal shells;
• wherein the longitudinal voids are positioned in the compressible rubber section, and wherein rubber on an outer surface of the compressible rubber section is forced into the longitudinal voids between and radially outwardly from the compressible rubber section when the bushing assembly is inserted into the hub.
