Abstract:
A rubber track made of an elastomer material, comprising:a strip forming a closed loop with an inside surface and an outside surface, said strip made mainly of an elastomer material and being reinforced by at least one reinforcement armature whose reinforcing elements are essentially orientated in the longitudinal direction of the strip; a plurality of relief elements projecting from the outside surface, said relief elements being intended to make contact with the ground to ensure good traction of the vehicle fitted with said rubber track; a plurality of guide teeth made of an elastomer material and projecting from the inside surface, said guide teeth comprising lateral faces and front and rear faces in the longitudinal direction; at least one insert arranged inside each guide tooth or inside each relief element on the outside surface; and each insert has a generally hollow shape forming a free volume, said free volume being able to absorb the thermal expansion of the elastomer material surrounding said insert in the guide tooth or relief element resulting from the increase in temperature during the molding and vulcanization of the elastomer material of each tooth of the rubber track.
