Abstract

acionamento por tração de velocidade variável toroidal um acionador por tração de velocidade variável toroidal é fornecido. o acionador compreende um disco de acionamento (11) e um disco acionado (10). os discos (10, 11) possuem um eixo geométrico comum de rotação. a face interna de cada disco (10, 11) é formada com um formato negativo de um toróide. o acionador compreende adiconalmente uma pluralidade de conjuntos de cilindro intercalados entre os discos (10, 11) cada conjunto de cilindro compreendendo um cilindro (1). os discos (10, 11) são empurrados juntos contra os conjuntos de cilindro intercalados por uma força de fixação. cada cilindro (1) de cada conjunto de cilindro contata cada disco (10, 11) nos pontos de contato (387, 39); cada conjunto de cilindro sendo conectado a um munhão rotativo correspondente (28); cada munhão (28) possuindo um eixo geométrico de rotação que passa através de uma cavidade toroidal formada pelas faces internas de formato opostos dos discos (10, 11); onde pela rotação de um munhão (28) em torno do eixo geométrico de rotação do munhão o munhão (28) aplica uma força de direcionamento ao conjunto de cilindro correspondente em um ponto relativo ao conjunto de cilindro correspondente; a força de direcionamento aplicada fazendo com que o cilindro (1) do conjunto de cilindro correspondente direcione e adote pontos de contato diferentes (38, 39); onde o ponto no qual a força de direcionamento é aplicada é localizado desviado do eixo geométrico de rotação de munhão em uma distância fixa e também localizado desviado de uma linha que forma uma interseção com os pontos de contato (38, 39).
