Patent number: 11655864Abstract: A brake pad for a motor vehicle is provided. The brake pad includes a body having an upper edge and a lower edge. The upper edge is configured for positioning relative to an outer diameter of a rotor. The brake pad also includes a friction surface extending between the upper edge and the lower edge for engaging the rotor. The brake pad further includes a relieved portion located along a section of the upper edge. The relieved portion is configured to reduce squeal noise caused by tangential modes of the rotor, during engagement of the brake pad with the rotor, by minimizing contact between the friction surface of the brake pad and the outer diameter of the rotor at an area of the rotor having a potential for high modal displacement in a tangential direction.Type: GrantFiled: August 16, 2019Date of Patent: May 23, 2023Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Yuri Anatoly Karpenko, Charles K. Evans, J. Chris Oakwood, Peter Kowalow

Patent number: 10309469Abstract: A friction damping cast component and method of production are disclosed. The components may be rotary, such as a cast brake rotor, or may be non-rotary, such as a cast suspension part or a cast engine block. Regardless of the type of component, a two-part vibration-damping insert having a thin metal core and a thin metal sheath is provided. The sheath fully encompasses the core in such a way that a dry sliding friction contact develops at their interfaces. The outer surface of the sheath with the metal core inside is rigidly bonded to the cast material that surrounds it during the casting process. The sheath surfaces may have a number of openings that allow a limited infiltration of molten cast iron material just inside the immediate vicinity of the sheath openings for spot rigid bonding between the surrounding cast material and the insert surfaces during casting.Type: GrantFiled: April 12, 2017Date of Patent: June 4, 2019Assignee: Ford Global Technologies, LLCInventors: Yuri A. Karpenko, David Allen, James Maurice Boileau, J. Chris Oakwood, Peter Kowalow, Laura Dammeyer, Steven Swisher, Robert Gordon Rentschler

Dry friction damped mechanical and structural metal components and methods of manufacturing the same
Patent number: 10060495Abstract: A method and system for increasing damping capacity in cast metal parts by utilizing dry friction between individual wires of a sheathed rope is disclosed. The rope is embedded into the part during casting. Sheathing the ropes in a thin layer of the same metal as the casting prevents molten metal from infiltrating individual wires during casting, thus allowing inter-wire friction during the part vibration. There are two ways to distribute the ropes within a part during casting. The first way is to distribute the ropes uniformly across an entire part whereby damping capacity of the metal part increases uniformly as well. The second way of distributing the ropes is to spatially distribute them according to a pattern to increase the damping capacity only in the part regions that have the highest vibration amplitudes or stress during system vibration. Both methods of distribution may be combined in a single part.Type: GrantFiled: September 15, 2016Date of Patent: August 28, 2018Assignee: Ford Global Technologies, LLCInventors: James Maurice Boileau, Yuri Anatoly Karpenko, J.
