Patent number: 6755403Abstract: 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 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: February 13, 2002Date of Patent: June 29, 2004Assignee: The Pullman CompanyInventors: James Lewis, Richard Novy, Robert Missig

Patent number: 5397112Abstract: A circular cylindrical elastomeric member is formed with an annular recess and two spaced apart pockets in communication with the recess. An outer metal tube receives an inner ring in interference fit in the tube bore, the ring having at least one peripheral depression in an outer surface and a pair of spaced apertures through the ring each communicating with a different corresponding aperture forming at least one channel communicating with the pockets and apertures which are congruent with the pockets. The member is axially forced into the ring and outer tube while submerged in an imcompressible hydraulic fluid to radially compress and elongate the member during member insertion and fill the channel and pockets with the fluid. The ring seats in the member recess. An inner tube is then axial forced into the bore of the elastomeric member and locked to the member by the radial compressive forces without vulcanization or a bonding agent.Type: GrantFiled: May 5, 1994Date of Patent: March 14, 1995Assignee: The Pullman CompanyInventors: Stephen F.
