FIELD: mechanical engineering; crawler vehicle. ^ SUBSTANCE: invention relates to tracks and track link joints. Proposed track chain contains tracks formed by links with outer and inner lugs and race for track rollers. Track chain contains also shoes coupled with links. Outer and inner lugs of links are connected by two pins in series. Bushings located between inner lugs are rigidly connected with pins. Pins are provided with beads on one end and cone on other ends. Grooves are made on outer lugs. Through axial dummy hole is made in one of each pair of pins. Shoes and links are made in form of solid cast structure forming tracks. Holes of outer and inner lugs accommodate stepped bushings cast integral with lugs. ^ EFFECT: improved manufacturability, reliability, repairability of track chain, reduced metal usage of tracks. ^ 3 cl, 2 dwg |
