Abstract

MECANISMO DE ACIONAMENTO PARA TRANSMISSãO INFINITAMENTE VARIáVEL. Uma transmissão de variador compreende um eixo de entrada (18), um disco de entrada (10) montado no eixo de entrada para rotação com ele e um disco de saída (12) opondo-se ao disco de entrada e disposto para girar coaxialmente entre eles, os discos de entrada e saida definindo entre eles uma cavidade toroidal. Dois roletes (14, 16) estão localizados na cavidade toroidal e primeiro e segundo dispositivos de carro de rolete são fornecidos sob os quais os primeiro e segundo roletes são respectivamente montados de modo rotatório e dispositivos de carga final (34, 36) urgem os roletes em contato com os discos de entrada e saida para transmitir acionamento. Os dois dispositivos de carro de rolete são montados em lados opostos do eixo geométrico pivotante de uma alavanca (50) e o eixo geométrico pivotante da alavanca (50) é movível na direção radial com respeito ao eixo geométrico rotacional dos discos de entrada e saída.
