HINGELESS RUBBER-REINFORCED TRACK FOR HARVESTER Russian patent published in 2010 - IPC B62D55/253 

FIELD: transport.

SUBSTANCE: invention relates to transport machine building. Hingeless rubber-reinforced track for harvester contains metal reinforcing elements made integral with track wheel guides and set at certain distance from each other throughout the length. Steel-wire cord is made as cable and wraps reinforcing elements from outside. Steel-wire cord and reinforcing elements are cured together in rubber into single endless chain with treads and bearing surface. On the bearing surface under each tread throughout track length, longitudinal projections are made at the edges of which there are transversal grousers. The grousers have chamfer towards track side faces. The bearing surface between longitudinal projections in its cross-section is made convex away from reinforcing element along ellipse curve and forms ellipsoid cavity throughout track length in longitudinal direction of track chain.

EFFECT: improvement of harvester flotation ability and decrease in destruction soil covering due to making track bearing surface concaved along ellipse curve.
