| 发明名称 | Resilient track frame pivot mechanism | ||
| 摘要 | 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. | ||
