An undercarriage assembly associated with a machine is provided. The undercarriage assembly includes a ground engaging track adapted to crawl on a ground surface. The ground engaging track includes a plurality of track shoes. The ground engaging track also includes a plurality of pairs of track links pivotally connected to one another. Each of the track links includes a body member having a first side surface and a second side surface. The body member also includes a mounting hole defined in the body member. The mounting hole extends angularly with respect to the shoe surface. The ground engaging track further includes a coupling mechanism. The coupling mechanism includes a coupling member adapted to be received within the mounting hole, and welded to the track shoe to couple each of the plurality of track shoes with the respective track links.

Undercarriage assembly

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. The method may still further include inserting a second portion of the seal assembly into a counterbore formed in an axial face of a second track link of the track joint assembly such that an axial sealing face of the washer opposite from the first track link slidably engages with the second portion of the seal assembly on the second track link of the track joint assembly to form a sealing surface between the first and second track links.

Laser brazing of annular metal seal member on track link

A construction machine includes a chassis, at least one continuous track supporting the chassis, at least one rim operatively associated with the continuous track, a shaft rotatably associated with the rim, and a collar operatively associated with the shaft and a guard plate. The collar has a variably angled face interfacing with the rim, and a labyrinth is formed between the collar and the rim via the variably angled face.

Track link

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.

Track joint assemblies

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.

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.

A roller for a machine undercarriage may include a roller body constructed from a single, unitary piece of parent material. The roller may also include a first roller tread disposed between a first end of the roller body and a second end of the roller body. Additionally, the roller may include a second roller tread disposed between the first and second ends of the roller body.

Roller for a machine undercarriage

An idler for a machine undercarriage includes a hub. The idler may also include a body extending radially outward from the hub, the body including a single solid disk with a first substantially planar side and a second substantially planar side opposite the first substantially planar side.
