Abstract: A clamping master track link (202) comprises a body (204) that defines a first bore (218) and a second bore (220), a first aperture (222) disposed between the first bore (218) and the second bore (220), a second aperture (224) disposed between the first aperture (222) and the second bore (220), a first strut (226) with a first gap (228) disposed between the first aperture (222) and the second aperture (224), a second strut (234) with a second gap (236) disposed between the first aperture (222) and the first bore (218), and a bridge (246) disposed between the second aperture (224) and the second bore (220).

Abstract: A track assembly (14) for a machine (10) includes a track (16) having inner track seals (54a, 54b), a rotatable track engaging element (20) such as an idler or drive sprocket and a contact interface (40a, 40b) or protecting the seals (54a, 54b) during guiding the track (16) about the rotatable element (20). The contact interface (40a, 40b) may include sacrificial wear material (42a, 42b) on the rotatable element (20) and sacrificial wear material (44a, 44b) on corresponding track links (24a, 24b). The contact interface (40a, 40b) may have a configuration based on a location of the seals (54a, 54b), and is adapted to inhibit wear of the track links (24a, 24b) in regions adjacent the seals (54a, 54b). In another aspect, the contact interface (40a, 40b, 140a) is a guide interface (40a, 40b).

Abstract translation: 用于机器（10）的轨道组件（14）包括具有内部轨道密封件（54a，54b）的轨道（16），诸如惰轮或驱动链轮的可旋转轨道接合元件（20）和接触界面（40a， 40b）或在围绕可旋转元件（20）引导轨道（16）期间保护密封件（54a，54b）。 接触界面（40a，40b）可以包括在可旋转元件（20）上的牺牲耐磨材料（42a，42b）和对应轨道连接件（24a，24b）上的牺牲耐磨材料（44a，44b）。 接触界面（40a，40b）可以具有基于密封件（54a，54b）的位置的构造，并且适于抑制邻近密封件（54a，54b）的区域中的轨道连杆（24a，24b）的磨损， 。 另一方面，接触界面（40a，40b，140a）是引导界面（40a，40b）。
