20090058182 | ENDLESS TRACK CHAIN ASSEMBLY WITH IN SITU REPLACEABLE WEAR PARTS - An endless track chain assembly for an endless track vehicle having drive teeth received in tapered slots in a drive wheel. The drive teeth are replaceable in situ by a movement in a direction parallel to the rotational axis of the drive wheel. The drive teeth inter-fit with tapered inserts on the endless chain assembly so that all the driving forces are transmitted between the two replaceable wear elements. The inserts are inter-connected with pairs of links in a three point mounting as a structural unit to increase torsional rigidity and enable bushings that inter-connect adjacent links to be smaller that conventional bushings. The inserts on the endless chain assembly are readily replaceable by fasteners accessed from the exterior of the endless chain assembly. | 03-05-2009 |
20100102623 | TRACK IDLER WITH REPLACEABLE WEAR PADS - An idler for use with an endless track of a track-type vehicle comprises a wheel and a rim. The rim comprises fasteners and replaceable wear pads releasably mounted to and positioned about the periphery of the wheel using the fasteners. | 04-29-2010 |
20100102624 | Dual-Bushing Track Chain Cartridge - An endless track chairs for use with a track-type vehicle comprises a cartridge joined to the links of first and second link sets for relative rotation between the link sets. | 04-29-2010 |
20110049975 | Track Chain Joint With Rotatable Pin - A track chain joint for an endless track chain of a track-type vehicle is configured to engage first and second sprockets of a drive wheel of the track-type vehicle. | 03-03-2011 |
20110198917 | Track Assembly With Symmetric Track Chain Link - A track chain link for use in an endless track chain has a longitudinal (or “x”) dimension and a lateral (or “y”) dimension. The track chain link has an x-y plane of symmetry about which the track chain link is symmetric. | 08-18-2011 |
20130092459 | TRACK CHAIN JOINT FOR A CRAWLER TYPE WORK VEHICLE - A track chain assembly for a crawler type work vehicle includes a plurality of links pivotally connected together at respective link joints.

20150060157 | RESILIENT TRACK FRAME PIVOT MECHANISM - The present disclosure provides a pivot joint about which a track frame pivots relative to a main frame of a work machine. The pivot joint includes a housing having a first cover portion, a second cover portion, and at least one load-bearing rib. The pivot joint also includes a holder configured to be coupled to the main frame and includes a first leg and a second leg. An upper body and a lower body are coupled to one another and are adapted to be coupled to the track frame. The pivot joint further includes a plurality of plates stacked on top of one another. The plurality of plates is positioned between the first leg and second leg of the holder and between the upper body and lower body. The plurality of plates defines a pivot axis of the pivot joint. | 03-05-2015 |
