Abstract

Anvelopa de pneu, prevazuta cu o armatura de vîrf, formata din cel putin doua straturi din fire sau cabluri, paralele între ele în interiorul fiecarui strat si impregnate, cu solidarizarea între ele. Cel putin în zonele cele mai distantate de planul ecuatorial al pneului straturile formeaza, fata de directia longitudinala a pneului, unghiuri avînd o valoare de cel putin 45 degree . De asemenea anvelopa este prevazuta cu o bara de rulare a carei suprafata de contact cu solul este mai îngusta decît arma tura de vîrf. Pe cel putin o latura a planului ecuatorial cele doua straturi ale armaturii de vîrf apar la suprafata laterala fata de controlul portiunii benzii de rulare, fara a veni în contact cu solul, lungimea lor axiala fiind cel mult egala cu jumatate din semilargimea axiala corespunzatoare a benzii de rulare, masurata în locul în care armatura de vîrf este la suprafata din banda de rulare. portiunea armaturii de vîrf ce iese la suprafata este acoperita din toate partile sale de un strat de cauciuc a carui suprafata marcheaza fata radiala, fiind distantata de o axa dee rotatie, inferioara acesteia a zonei de contact cu solul. Cele doua straturi ale armaturii de vîrf iese la suprafata cu o lungime axiala inferioara la 20%, de preferinta de 4...10% din semilungimea axiala a benzii de rulare în punctul de iesire. Largimile axiale ale straturilor de vîrf masurate între planul ecuatorial si extremitatile acestora valoarea maxima a latimii axiale exterioare a anvelopei de pneuri masurata la nivelul flancurilor. Inventia se aplica în industria prelucrarii cauciucului.
