Abstract: An undercarriage assembly for a mobile machine includes a continuous track having a plurality of mated track links that can translate with respect to the machine. Each track link may include a shoe portion and a body portion. The body portion includes a plurality of projecting pin lugs each having a pin bore to receive a bin and link adjacent track links together. The pin lugs can include a pair of sprocket lugs for making rolling contact with a sprocket, a pair of roller lugs for making rolling contact with a plurality of rollers, and a side lug having a protruding shoulder to assist in aligning the plurality of rollers.

Abstract: A cartridge assembly for a track chain includes a bushing and a track pin. The bushing has an outer surface and an inner surface, the inner surface defining a passage in the form of a cylindrical bore. The bushing forms a lubrication reservoir adjacent the inner surface and extending towards the outer surface of the bushing. The track pin is disposed within the cylindrical bore, and the bushing is rotatable with respect to the track pin. An outer surface of the track pin is in fluid communication with the lubrication reservoir. The outer surface of the bushing corresponds with an outer diameter of the cartridge assembly. The outer diameter of the cartridge assembly is less than a diameter of supporting bores such that the cartridge assembly is rotatable with respect to inside surfaces of the supporting bores.

Abstract translation: 用于履带链的卡盘组件包括衬套和轨道销。 衬套具有外表面和内表面，内表面限定了圆柱孔形式的通道。 衬套在内表面附近形成润滑容器并且朝衬套的外表面延伸。 轨道销布置在圆柱形孔内，衬套可相对于履带销旋转。 轨道销的外表面与润滑油箱流体连通。 衬套的外表面对应于盒组件的外径。 盒组件的外径小于支撑孔的直径，使得盒组件相对于支撑孔的内表面是可旋转的。
