Abstract

Perfeccionamientos en mecanismos de transmisión continuamente variable, del tipo que incorporan un variador que tiene un primer manguito de diámetro efectivo ajustable sobre un primer eje geométrico; un segundo manguito de diámetro efectivo ajustable sobre un segundo eje geométrico; una banda flexible de transmisión que une entre sí las dos poleas comprendiendo cada polea una mitad de polea axialmente fija y una mitad de polea axialmente móvil; una garganta en V para la banda de transmisión formada por superficies inclinadas y mutuamente encaradas de las mitades de polea y los medios de ajuste para empujar la mitad móvil de la polea hacia la mitad fija de la polea con el fin de ajustar la anchura de la garganta en V y, por lo tanto, el diámetro efectivo de la polea para acoplamiento con la banda, encarándose la mitad móvil de cada polea a la mitad fija de la otra polea con el fin de mantener la alineación de la banda con las poleas en una gama de ajuste y situándose los medios de ajuste para la segunda polea al lado de la mitad móvil de la polea opuesta a la mitad fija de la polea, caracterizados porque los medios de ajuste para la primera polea se sitúan al lado de la mitad fija de la polea opuesto a la mitad móvil de la polea por lo que ambos dispositivos de ajuste quedan en el mismo lado de la banda.
