ADDITIONAL SIDEWALL ARMATURE FOR A HEAVY GOODS VEHICLE TYRE

摘要

#CMT# #/CMT# The tire (10) has a radial carcass reinforcement (2) surmounted radially outside by a crown reinforcement (31), and with metallic stiffeners coated in a rubber coating material. The carcass reinforcement is anchored in beads (4) contacting a mounting rim, and one of walls (1) is extended between the corresponding bead and a crown (3). One wall includes an additional reinforcement (5) with two sets of parts having breaking strengths such that the strength of one set of parts is lesser than that of the other set of parts, where the parts are alternately arranged in a circumferential direction. #CMT# : #/CMT# The additional reinforcement has textile stiffeners chosen among textile stiffeners with polyamide/aramid nature or hybrid stiffeners formed of textile stiffeners with different natures. #CMT#USE : #/CMT# Tire for a heavy vehicle. Can also be used for an aircraft, work vehicle and agricultural vehicle. #CMT#ADVANTAGE : #/CMT# The additional reinforcement forms a barrier to the propagation of breakage of the metallic stiffeners, while limiting the circumferential length of an opening on one of the walls of the tire, thus reducing blast effect produced by the burst of the tire. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a meridian sectional view of a tire. 1 : Tire 2 : Radial carcass reinforcement 3 : Crown 4 : Beads 5 : Additional reinforcement 10 : Tire 31 : Crown reinforcement.
