Abstract

An improved polymeric knuckle pin with at least one indented area that elastomer rings rest in. The indented area is strategically placed in an area on the shaft of the pin where the coupler-knuckle connection exerts impact, force, and stress on the pin. The elastomer rings in the indented area provide cushion to the pin from the impact, force, and stress, allow the pin to avoid hard contact with the coupler and knuckle, distribute the loads exerted by the coupler and knuckle more evenly, realign the coupler and knuckle positions, and protect the pin itself from surface cuts and scratches. The elastomer rings on the shaft of the pin improve the life of both the coupler-knuckle assembly and the pin.
