Abstract

"SUB-CAMADA DE TECIDO PARA MELHORAR A RIGIDEZ CIRCUNFERENCIAL E MERIDIONAL" Trata-se de um pneu para carro de passageiros com lona radial (10) que tem uma banda de rodagem (12), uma carcaça (25) com dois costados (18, 19), duas ou mais lonas radiais (30, 40), dois talões anulares (26), uma estrutura de cinta (16) localizada radialmente entre a estrutura de banda de rodagem e a estrutura de lona radial 37) e uma sub-camada de tecido (60) distribuída entre a carcaça e a estrutura de cinta. A sub-camada (60) contém fibras ou cordas co alto módulo alinhadas circunferencialmente (62) que, em combinação com a estrutura de cinta do metal (16) induz pré-tensões compressivas na estrutura da correia, aumentando assim a rigidez da estrutura de cinta e banda de rodagem sobreposta. Em particular, a sub-camada de tecido (60) induz maior resistência da banda de rodagem a abaulamento para cima de seu centro durante a operação de rodar vazio e também retarda a formação de ondas estacionárias na banda de rodagem (12) e costados (18, 19) durante a operação a alta velocidade com inflação normal."FABRIC SUB-LAYER TO IMPROVE CIRCUMFERENTIAL AND SOUTHERN RIGIDITY" It is a passenger car tire with radial tarpaulin (10) that has a tread (12), a carcass (25) with two sides (18 , 19), two or more radial plies (30, 40), two annular beads (26), a belt structure (16) located radially between the tread structure and the radial canvas structure 37) and a sub- layer of fabric (60) distributed between the carcass and the strap structure. The sub-layer (60) contains fibers or ropes with high modulus circumferentially aligned (62) which, in combination with the metal strap structure (16) induces compressive pre-stresses in the belt structure, thus increasing the rigidity of the belt structure. strap and superimposed tread. In particular, the fabric sub-layer (60) induces greater resistance of the tread to bulging upward from its center during the empty run operation and also slows the formation of stationary waves in the tread (12) and sides ( 18, 19) during high speed operation with normal inflation.
