Abstract

POLIA TENSORA DE CORREIA COM ELEMENTO AMORTECEDOR. A presente invenção refere-se a uma polia tensora (10, 70, 110) para a tensão de uma correia, que compreende um alojamento de suporte (12, 84, 130), definindo pelo menos em parte, uma cavidade de mola (16). Um elemento amortecedor (24, 72, 112) que apresenta uma primeira superfície de apoio de fricção (56; 96, 98; 164, 166) está, pelo menos parcialmente, disposta na cavidade de mola (16). Um braço (14) provido de eixo central e conectado ao alojamento de suporte (12, 84, 130) apresenta uma segunda superfície de apoio de fricção (58, 114). Uma mola (18, 118) está localizada na cavidade da mola (16) e conectada de modo operante ao braço (14) e ao elemento amortecedor (24, 72,112) para fazer girar o elemento amortecedor em torno de uma posição de eixo de modo tal que a primeira superfície de apoio de fricção (56; 96, 98; 164, 166) do elemento amortecedor (24, 72, 112) fica predisposto contra a segunda superfície de apoio de fricção (58, 114) do braço (14) para amortecer o movimento relativo entre o braço (14) e o alojamento de suporte (12, 84,130).
