Abstract: A track link is fixable to a track shoe with nuts and bolts. The track link comprises connecting holes that are spaced in a link pitch direction and receive connection members, first and second through holes that extend orthogonally to the connecting holes and receive bolts, a first surface in which the first through hole opens and on which a first nut is positionable, a second surface in which the second through hole opens and on which a second nut is positionable, first projecting portions that project from the first surface and face each other across the first through hole, and second projecting portions that project from the second surface and face each other across the second through hole. Only one of the first projecting portions engages the first nut. At least one of the second projecting portions engages the second nut that is positionable between the second projecting portions.

Abstract: A track link for a ground-engaging track system includes an elongate link body having an upper rail surface located in part upon each of a first link strap, a second link strap, and a middle section of the track link. The upper rail surface is formed by a wear band of sacrificial wear material having a hardness that is varied lengthwise along the upper rail surface to retard scalloping of the track link during service and forming relatively softer zones in the first and second link straps and a relatively harder zone within the middle section. Methodology for making such a track link is also disclosed.

Abstract: Traction enhancing detachable spikes are disposed on, and between, the grousers and the shoes of continuous tracks of motorized vehicles such as bull dozers, excavators, tanks, skid steers and the like. Spike receptacles are permanently affixed to the track of continuous track construction machinery, which spike receptacles house outwardly protruding spikes. The spikes are easily detachable and removable from the spike receptacle to facilitate use of the subject motorized vehicles on flat and graded surfaces, such as pavement.

Abstract: The present invention is directed generally to track segments for track vehicles and, more specifically, to a track segment having an ethylene propylene diene monomer (EP(D)M) rubber based backer, and a method of making. In one embodiment, the track segment includes an EP(D)M rubber based backer including a rubber compound having 100 phr EP(D)M rubber wherein the diene component is optionally present, a peroxide curing agent, and one or more acrylic and/or methacrylic coagents. The track segment further includes a track pad and a track body. The track pad and backer cooperate with the track body to define the track segment for use in a track for a track vehicle. The EP(D)M rubber based compound provides a desirable balance of low heat build-up under heavy dynamic cyclic compression conditions, and also has a desirable load carrying capability, high heat resistance, and good cut/tear strength in hot climates.

Abstract: Undercarriage assembly components of track-type machines having a PTA welded wear-resistant coating and methods for forming such coated undercarriage assembly components are disclosed. Bodies of the undercarriage assembly components, formed of an iron-based alloy, have a material PTA welded on a surface or into an undercut or channel of the iron-based alloy. A heat treatment of the formed component further hardens the body. The portion of the outer surface of the undercarriage assembly components having the wear-resistant coating corresponds to a wear surface of the component during operation of the endless track of the track-type vehicle.

The pin is located within the tubular supports by elastomeric bushings that accommodate relative pivotal movement by torsional deflection.

Abstract: In the operation of a track type machine in highly abrasive material, premature wear of the track shoes has been a common occurrence. The present invention provides a track shoe that has a grouser that defines a plurality of grooves that extend in a direction that is substantially the same as that of the grouser. The grooves are formed on both the leading and trailing sides of the grouser and are filled with an abrasion resistant material. The grooves are arranged such that the strips of abrasion resistant material on the first side are aligned with the spaces between the strips on the opposite side and vice versa.

Abstract: The stamped-metal clip is suitable for use with an endless track belt cooperating with slide rails. The clip comprises a main portion having a hardened bearing surface to be engaged against at least one of the slide rails. The bearing surface has a hardness greater than 35 HRC, preferably between 40 and 60 HRC. The clip further comprises an unhardened fastening portion comprising two curved wings to clamp the main portion to the track belt without rupture. These curved wings have a hardness smaller than the hardness of the bearing surface, preferably smaller than 35 HRC. The hardness of the bearing surface makes it resistant to wear and friction and the smaller hardness of the wings enables the clip to be clamped to the track belt without rupture.

Abstract: Improved snowmobile acceleration and higher snowmobile top speeds can be obtained using a studded snowmobile belt track with lightweight studs preferably made of aluminum. Higher snowmobile top speeds and improved snowmobile acceleration are accomplished because aluminum studs weigh as much as 66 percent less than conventional steel studs. The aluminum studs can be push-through type studs with or without a spade face, or T-nut type studs with or without a spade face. Spade faces on the push-through studs are preferably tapered at 5.degree. in relation to a longitudinal axis of the stud. Push-through type studs preferably have a grip ridge that projects from the head of the stud into the snowmobile belt to prevent bulging of the belt near the stud.

Abstract: A crawler block rubber pad for a crawler which has an endless path of movement and which is used for a vehicle. Links are axially supported and connected by pins in an endless shape, and crawler blocks are attached to outer surfaces of the links. In the crawler block rubber pad, a rubber pad is formed integrally, by vulcanization and adhesion, to an outer side surface of a crawler block and to end portions of the crawler block as seen from a longitudinal direction of the links. Preferably, the rubber pad is vulcanized and adhered to both end portions of the crawler block in the longitudinal direction of the links. Even if a small stone or the like becomes caught in a space between crawler blocks which space widens when the crawler is trained around an idler or the like, because a thickness of rubber material is provided so as to be larger than a radius of a small stone, no unwanted force is applied to the pins and the links.
