Publication number: 20110316209Abstract: A dual rate shock absorbing apparatus for a suspension system of a heavy off-road vehicle including a housing having two axially elongated members. A dual rate spring package is disposed in the housing. Such spring package includes a first spring assembly for absorbing, dissipating and returning a first predetermined level of energy imparted to the shock absorbing apparatus. One end of the first spring assembly acts against a closed end of the housing and a second end acts against a spring seat. A second spring assembly absorbs, dissipates and returns a second predetermined level of energy. One end of the second spring assembly acts against an opposed closed end of the housing and a second end acts against the spring seat. An axially elongated guide assembly, extending substantially the cumulative length of the first and second spring assemblies, controls axial compression of the first and second spring assemblies.Type: ApplicationFiled: June 24, 2010Publication date: December 29, 2011Inventors: Ronald W. KERR, Richard J. BERANEK

Patent number: 8061695Abstract: A device of the invention includes a vibration isolator with an elastomeric damper and inner and outer connectors. The inner connector has external and internal threads, and the outer connector has internal threads. A method of the invention includes attaching the vibration isolator to a block by screwing external threads of an internal connector of the isolator into the block. The block with attached isolators is inserted into an enclosure, and each isolator is loosened as necessary to make a flush fit with the enclosure. A screw is then inserted into each isolator and fastens the isolator to the block at the flush position. Finally, a screw is inserted through the enclosure into each isolator to connect the isolators to the enclosure.Type: GrantFiled: June 6, 2007Date of Patent: November 22, 2011Assignee: Honeywell International Inc.Inventor: Nicolas D.

Patent number: 8061698Abstract: A geometric shaped side bearing pad includes a top and a surface extending an angle ? towards the top, wherein the bearing pad has a geometric shape and a non-linear spring rate which levels out a reaction force without buckling. The surface of the bearing pad can have two sides or four sides, can have spacing within the surface, or can be solid. The angle ? can be within the range of about 20 degrees and 85 degrees, and may preferably be within the range of about 30 degrees and 45 degrees to achieve non-linear load/deflection. The top of the bearing pad can have a slot defined therethrough to accommodate a protrusion in a fixture to engage the bearing pad. The bearing pad can provide a friction contact with an object and enables lateral force transfer to the bearing pad, thereby providing lateral stiffness.Type: GrantFiled: October 20, 2006Date of Patent: November 22, 2011Assignee: Chemtura CorporationInventor: Richard L.

Patent number: 8042793Abstract: A mounting scheme for attaching a power train to a motor vehicle frame includes a plurality of mounts. At least one of the mounts is a solid engine mount having a metal housing and an elastomeric bushing. The elastomeric bushing contains no voids other than a central bore used to attach the mount to a bracket. The elastomeric bushing includes frustoconical portions, where one end of each of the frustoconical portions is unconstrained by the metal housing. The stiffness of the mount may be tuned to reduce noise and improve handling. The stiffnesses of any of the axes may be adjusted so that the power train roll center aligns with the power train center of gravity.Type: GrantFiled: September 6, 2006Date of Patent: October 25, 2011Assignee: Honda Motor Co., Ltd.Inventor: Hajime Igami

Publication number: 20110133380Abstract: The present invention provides an improved Micro Cellular Urethane (hereinafter ‘MCU’) bump stop/spring aid having a plurality of struts adapted to level the rate transition as sections are folded onto one another. MCU bump stops/spring aids are well known in the art to assist vehicle suspension systems. More particularly, bump stops/spring aids are frequently used with vehicle suspension systems in connection with shocks and strut assemblies. These assemblies provide a comfortable ride in addition to influencing the control and handling of the vehicle. The struts are positioned around the circumference of the MCU bump stop/spring aid. The added struts between the undercuts partially support the outer surfaces of the MCU bump stop/spring aid. Struts are generally molded between the outer surfaces. Struts may also be molded on an inner surface. The plurality of struts improves upon existing technology by improving performance characteristics.Type: ApplicationFiled: December 8, 2010Publication date: June 9, 2011Applicant: Trelleborg YSH, Inc.Inventors: James D.
