Document Type and Number:
WIPO Patent Application WO/2022/007595
Kind Code:
A1
Abstract:
An excavator linkage, a linkage assembly, and an excavator linkage lubricating system. The excavator linkage comprises: a main plate body (10), wherein hinged shaft sleeves are respectively arranged at the upper and lower ends of the main plate body, lubricating point locations are provided in the hinged shaft sleeves, and a distributor mounting structure is arranged on the main plate body (10), and is used for mounting a grease distributor (2) on the main plate body (10); and a plurality of in-plate flow channels which comprise oil output flow channels, wherein outer ports of at least some of the oil output flow channels extend to the edge of the main plate body or a position close to the edge, and are used for being in communication with the lubricating point locations in the hinged shaft sleeves; and inner ports of the in-plate flow channels are located on the same side plate face of the main plate body, mutually gather in a mounting area (20) of the grease distributor, and are in communication with corresponding oil openings of the grease distributor (2) after the grease distributor (2) is mounted on the main plate body (10). When the excavator linkage is used, oil is supplied to the lubricating point locations by means of the in-plate flow channels inside the main plate body (10), such that the excavator linkage has a simple structure and is aesthetic, and an oil way cannot be damaged, thereby ensuring the reliability of oil supply and lubrication.
