Embodiment Construction

[0019] figure 2 An exemplary track assembly 100 for a track-type machine is shown. For example, a tracked machine may be a loader, tractor, excavator, tank, or another mobile machine with tracked traction. When in operation, a drive sprocket of a track-type machine (not shown) may rotate track assembly 100 about one or more idlers or other guiding members (not shown) to facilitate movement of the track-type machine.

[0020] Track assembly 100 may include a series of links 100a interconnected to each other and to a series of links 110b by laterally disposed pins 120 . As shown, links 110a and 110b may be offset links. That is, they may have inwardly deflected ends 140a, 140b and outwardly deflected ends 150a, 150b. The inwardly deflected end 140a, 140b of each link 110a, 110b may be joined to the outwardly deflected end 150a, 150b of each adjacent link 110a, 110b. Additionally, the inwardly deflected end 140a of each link 110a may be coupled to the inwardly deflected end 1...

Abstract

Disclosed are various exemplary embodiments of a thrust ring for a track joint assembly. In one exemplary embodiment, the thrust ring may include a generally cylindrical outer surface. The thrust ring may also include a generally cylindrical inner surface including at least one protrusion extending toward a central axis of the thrust ring.

Description

technical field [0001] The present disclosure relates generally to track assemblies, and more particularly to track joint assemblies for engaging linkages of track assemblies. Background technique [0002] Many earth-moving machines, such as, for example, loaders, tractors, and excavators, include a tracked undercarriage to facilitate movement of the machine over the ground. Such undercarriages include drive sprockets that cause the track assemblies to rotate about one or more idlers or other guide members to propel the machine on the ground. Each track assembly includes a pair of parallel chains, each chain consisting of a series of links interconnected by pins and / or bushings (the combination of which is sometimes called a box assembly). Undercarriage maintenance costs often constitute more than a quarter of the total costs associated with operating an earth moving machine due to the extreme wear and tear experienced during use and impacts. [0003] FIG. 1 provides an ex...
