Abstract: A method of manufacturing an undercarriage track joint assembly includes forming at least a first portion of a seal assembly by laser brazing an annular, metal sealing washer to a first track link of the undercarriage track joint assembly. The method may also include performing the laser brazing to form at least one of an annular fillet of braze material between the first track link and at least a portion of an inner diameter surface of the washer and an annular fillet of braze material between the first track link and at least a portion of an outer diameter surface of the washer.

Abstract: Disclosed are various exemplary embodiments of a track joint assembly. In one exemplary embodiment, the track joint assembly may include a first link having a first bore. The track joint assembly may also include a second link having a second bore. Additionally, the track joint assembly may include a pin positioned at least partially within the first bore. The track joint assembly may also include an inner bushing positioned coaxially around the pin, and at least partially within the second bore. In addition, the track joint assembly may include an outer bushing positioned coaxially around the inner bushing. The track joint assembly may also include a seal assembly positioned between the first link and the second link to form a hermetic seal between the first link and the second link.

Abstract: Disclosed are various exemplary embodiments of a track joint assembly. In one exemplary embodiment, the track joint assembly may include a first link having a first bore. The track joint assembly may also include a second link having a second bore. In addition, the track joint assembly may include a solid pin positioned at least partially within the first bore. The track joint assembly may also include a bushing positioned coaxially around the pin. The bushing may include an axial end portion disposed in the second bore. The second link may include a sealing portion surrounding an axial end of the axial end portion. The sealing portion may include material having a different wear resistance than material of another portion of the second link.

Abstract: A track link assembly is disclosed for a machine. The track link assembly may include a first track link having a first thru hole and a second track link having a second thru hole aligned with the first thru hole. The track link assembly may further include a track pin disposed within the first and second thru holes. The track pin may have an end protruding from the first and second track links. The track link assembly may also include a ring-shaped flange integrally formed from the end of the track pin after insertion of the track pin into the first and second track links. The ring-shaped flange may have an outer diameter larger than a diameter of the first and second thru holes.

Abstract: Disclosed are various exemplary embodiments of a track joint assembly. In one exemplary embodiment, the track joint assembly may include a first link having a first bore. The track joint assembly may also include a second link having a second bore including first and second portions. The first and second portions may have different diameters. In addition, the track joint assembly may include a solid pin positioned at least partially within the first bore. The track joint may also include a bushing positioned coaxially around the pin. The bushing may include an axial end portion disposed in and contacting the first portion of the second bore. The bushing may also include an axial end-adjacent portion disposed in and contacting the second portion of the second bore. An outer diameter of the end-adjacent portion may be larger than an outer diameter of the end portion.
