Title
(PT) Método para correção de uniformidade depneumáticos
Abstract
(PT)
"MéTODO PARA CORREçãO DE UNIFORMIDADE DEPNEUMáTICO". Um método para correção de força direcional depneumáticos que corrige simultaneamente força radial e tangencialexercida pelo pneumático (12). O método permite a correção deforças tangenciais independentemente da direção de rotação dopneumático (12). Esta invenção atinge este objetivo através deuma técnica aperfeiçoada de correção de forças, em que sãoutilizadas pelo menos duas rodas giratórias (16, 24). No métodoinventivo, a direção de rotação de um desbastador (16) estáinvertida em relação à direção de rotação do (s) outro (s)desbastador (es) (24). Deste modo, pelo menos um desbastador(16) engatará o pneumático em um modo de "desgasteascendente" e pelo menos um desbastador (24) engatará opneumático em um "modo de desgaste descendente". O resultadoé que através da largura da superfície de banda de rodagem dopneumático (12), alguns blocos de banda de rodagem terão umaaparência de "calcanhar-para-artelho", enquanto que outrosparecerão artelho-para-calcanhar". O efeito é que, não importa adireção em que o pneumático está girando enquanto em uso emum automóvel, a variação da força tangencial foi reduzida.
