FIELD: transport engineering; crawler vehicles. ^ SUBSTANCE: proposed track chain contains links connected by pins and provided with eyes with holes of edges to receive connecting pins. Grousers in form of straight-line ribs arranged in parallel with pin axis are made on outer side of link. Track chain is furnished additionally with axle for fastening grousers, two floating bearings and two rubber bands. The latter are arranged in body of links and connected to provide rigid fastening of grousers on their axle. Said axle is installed by ends on two floating bearings, each secured on its rubber band. Grousers can freely rotate around axle within the limits of space. Space is made inside link to that its wall in direction of vehicle movement is made square to support surface of link, and upper part and opposite wall are made in form of common spherical surface providing angle of rocking of grouser equal to angle between support surface and surface of link at moment of their touching. ^ EFFECT: reduced energy consumption at operation of track unit, reduced negative action onto surface of ground, increased traction and coupling properties. ^ 1 dwg |
