Patent number: 8777245Abstract: A torque rod assembly includes a pair of end joint assemblies with a thin wall connecting tube disposed between them. The end joint assemblies each include an eye which is friction welded to the thin wall connecting tube. The use of the thin wall connecting tube and the friction welding process allow the friction weld to be located immediately adjacent a bore extending through the eye. The eyes and the thin wall connecting tube can be cast, extruded or formed from steel, aluminum or cast iron.Type: GrantFiled: November 16, 2012Date of Patent: July 15, 2014Assignee: The Pullman CompanyInventor: Christopher G.

Publication number: 20140077428Abstract: A mount having a bolt through configuration couples two components of a vehicle. The mount includes a first elastomeric member that defines a first portion of a first chamber and a second elastomeric member that defines a second portion of the first chamber and defines a second chamber. An inner tube assembly defines an opening for receiving the bolt. The first and the second elastomeric members are bonded to the inner tube assembly. An annular member is disposed between the first and the second chambers. The annular member defines a fluid-track which fluidly couples the first and the second chambers. The mount dampens vibrations at varying amplitudes by pushing fluid between the first and the second chambers via the fluid-track. The mount may also include a decoupler by way of a decoupler ring and decoupler cap to isolate the mount at a predetermined amplitude at varying frequencies.Type: ApplicationFiled: September 17, 2013Publication date: March 20, 2014Applicant: The Pullman CompanyInventors: Zoren E. Gaspar, Jay W. Thornhill

Patent number: 8646761Abstract: An elastomeric isolator has an elastomeric body which incorporates an inner structural member and an outer structural member. The elastomeric body includes a shear hub extending between radial flanges defined by the inner and outer structural members that undergo shearing stresses during deflection of the elastomeric isolator. The inner and outer structural members are designed to provide a travel stop for the elastomeric isolator in order to avoid compression of the shear hub during high loads. The elastomeric bushing can also include an optional integral elastomeric heat shield which protects the shear hub.Type: GrantFiled: November 21, 2012Date of Patent: February 11, 2014Assignee: The Pullman CompanyInventor: Troy P. Rodecker

Patent number: 8453787Abstract: A V-shaped torque rod includes an apex joint assembly that is attached to a component of a vehicle using only a single fastener. The apex joint assembly includes a housing, an inner metal, an elastomeric member disposed between the housing and the inner metal and a post that engages the inner metal. The single fastener extends through the inner metal and through the post to secure the apex joint assembly to the vehicle. The post can be a tapered post or the post can be a non-tapered post.Type: GrantFiled: February 7, 2011Date of Patent: June 4, 2013Assignee: The Pullman CompanyInventors: Christopher G. Rager, Kenneth A. McGill, Joseph F. Cerri, III, Russell E. Butler

Patent number: 8366069Abstract: An isolator assembly includes an elastomeric assembly which is disposed within a socket defined by a supporting structure. The socket defines a transition portion, a retention rib and a stopping rib. The elastomeric assembly is positioned in the socket by sliding the elastomeric assembly through the transition portion so that the elastomeric assembly is compressed as it moves into the retention rib. The stopping rib engages an end surface of the elastomeric assembly once it has been properly positioned in the socket.Type: GrantFiled: January 19, 2011Date of Patent: February 5, 2013Assignee: The Pullman CompanyInventor: Troy P. Rodecker

Patent number: 8347702Abstract: A testing machine tests the durability of backer pads on the track shoe assembly and the surface of the road wheel. The test machine utilizes two eccentric drives to move a section of a road wheel to simulate actual vehicle conditions. A positioning system positions the track shoe assembly with respect to the road wheel to adjust the loading between the two components.Type: GrantFiled: August 4, 2010Date of Patent: January 8, 2013Assignee: The Pullman CompanyInventor: Kenneth A.

Patent number: 8231115Abstract: A hydraulic mount has an upper support member and a lower support member. An upper elastomeric spring and a lower elastomeric spring are disposed between the upper support member and the lower support member to define an upper fluid chamber and a lower fluid chamber. A channel extends between the upper and lower chambers. During compression and extension of the hydraulic mount, fluid transfers between the upper and lower chamber to provide a damping force for the hydraulic mount.Type: GrantFiled: March 4, 2009Date of Patent: July 31, 2012Assignee: The Pullman CompanyInventors: Robert J. Goudie, Zoren E. Gaspar
