Publication number: 20080164645Abstract: 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.Type: ApplicationFiled: January 10, 2007Publication date: July 10, 2008Applicant: The Pullman CompanyInventors: Robert J. Bost, Ronald J. McLaughlin

Publication number: 20070063401Abstract: An elastomeric isolator has an elastomeric body which defines a void extending into the elastomeric body from one side and a void extending into the elastomeric body from the opposite side. One member for attaching the elastomeric body to a component is located inside of the two voids and another member for attaching the elastomeric body to a component is located outside of the two voids. The two voids overlap a specified distance to determine the stresses and stiffness for the isolator.Type: ApplicationFiled: September 22, 2005Publication date: March 22, 2007Applicant: The Pullman CompanyInventor: Troy Rodecker

Patent number: 7114712Abstract: A stabilizer bar assembly has a stabilizer bar and a pair of bushing assemblies. Each bushing assembly has an elastomeric bushing disposed around the stabilizer bar and an outer metal member disposed around the elastomeric bushing. The elastomeric bushing has a molded in rate plate to increase the stiffness of the elastomeric bushing. The outer metal member compresses the elastomeric bushing between the stabilizer bar and the outer metal member to a prespecified percent of compression. When the stabilizer bar rotates with respect to the outer metal member, the compression of the elastomeric bushing stops movement between the elastomeric bushing and the stabilizer bar and between the elastomeric bushing and the outer metal member. A fastening strap is attached to the outer metal member to attach the stabilizer bar assembly to a vehicle.Type: GrantFiled: June 28, 2004Date of Patent: October 3, 2006Assignee: The Pullman CompanyInventors: James Lewis, Richard Novy, Robert Missig, Robert Ferguson, Andrew Franzen

Patent number: 6854917Abstract: A pivot has a low friction rotational property by allowing the elastomeric bushing to rotate with respect to the inner metal. A low friction material can be incorporated between these two components to facilitate the rotation, if desired. The elastomeric bushing helps to isolate the pivot joint and prevent the transmission of vibrations. In one embodiment, the elastomeric bushing is also allowed to pivot about an axis generally perpendicular to its axis of rotation.Type: GrantFiled: February 12, 2002Date of Patent: February 15, 2005Assignee: The Pullman CompanyInventors: Edward M.
