    摘要: An elastomer bushing having an increased axial rate, improved durability, and high fatigue life due to the compression and confinement of the rubber element is provided. The manufacture of the elastomer journal is conventional for commercial vehicle applications. In a primary embodiment, the rubber is bonded to a bar pin by an adhesive, wherein the rubber journal is then subsequently assembled into an outer tube. After assembly, the outer tube is curled to retain the rubber journal, and the center of the outer tube diameter is swaged or compressed so as to deform the outer tube into the rubber. The compressed groove in the outer tube comprises the unique feature of this bushing design. This groove provides a mechanical “footing” that resists movement when an axial load is applied.
