MUMBAI, India, Nov. 14 -- Intellectual Property India has published a patent application (202517095596 A) filed by Caterpillar Inc., Peoria, U.S.A., on Oct. 5, for 'ultra-deep induction hardening for track pads.'
Inventor(s) include Magner, Scott Howard; Dumitru, Mircea; Loeffler, Brian Konrad; Maniruzzaman, Mohammed; Li, Yongqiang; and Jiang, Simon.
The application for the patent was published on Nov. 14, under issue no. 46/2025.
According to the abstract released by the Intellectual Property India: "Disclosed herein is an example track pad (112) having a ground-contacting portion (202) for use in a track-based machine (100) to propel and support the machine (100) across a supporting surface. The track pad (112) may be a track pad (112) that forms a link of a chain forming the track (102) for the track-based machine (100). The track pad (112) includes a cast body (114) formed of a first alloy steel having a first strength and toughness. The track pad (112) includes a roll path (116) that contacts a roller (502) of the track-based machine (100). The roll path (116) is hardened through an induction hardening process to achieve a hardness level at a depth of 32 millimeters or more from the surface of the roll path (116). The roll path (116) is shaped and positioned to contact rollers (110) of the track drive assembly and thereby reduce wear and fatigue on the track pad (112) as a result of contact and force transferred through the roller (502)."
The patent application was internationally filed on Feb. 21, 2024, under International application No.PCT/US2024/016594.
