TRACK CHAIN OF VEHICLE Russian patent published in 2009 - IPC B62D55/18 

FIELD: mechanical engineering.

SUBSTANCE: track chain contains tracks formed by links having internal and external lugs linked together by fingers. The external lugs contain rigidly connected bushings, while internal lugs are made as cast-solid structure with bushings for the drive wheel of tracking driver. Bushings of the external lugs are represented as cups. Circular stepped bores are made on the external surfaces of the cups from the side of dead end. The fingers are installed at radial clearance with regard to cups and bushings of the internal lugs and at axial clearance relative to cup ends.

EFFECT: improved operational reliability and durability of track chain, reduced manpower effort during repair.
