FIELD: transport.SUBSTANCE: track chain of running gear contains tracks interconnected by means of pins and braces with cogs. Track represents support plate with holes for pins, grousers provided on its face side, transversally oriented and spaced apart along length, and guiding flanges provided on its rear side, longitudinally oriented and spaced apart along width forming rail for single-row track roller groups of running gear, as well as with paired left and right wideners made of elastic material with reinforcing cord. The support plate is made as metal tray with niche at its outer side, with turned-out front and rear edges with creation of the mentioned grousers and with load-bearing elements. Length of load-bearing elements corresponds to track length. The wideners are structurally combined into single piece-insert the central part of which forming common base is recessed in tray niche and left and right parts are positioned outside the tray with possibility to interact with ground.EFFECT: better floatation, simplification of track chain design and higher reliability.5 cl, 10 dwg |
