Abstract
Polea (12) motriz para una transmisión (10) continuamente variable, siendo la polea (12) motriz susceptible de ser montada coaxialmente en torno a un eje (16) motriz, y giratoria a una velocidad de giro variable, comprendiendo la polea (12) motriz: una primera pestaña (22), que tiene un lado dotado de una pared (22a) cónica; una segunda pestaña (24), que tiene un primer y un segundo lados opuestos, siendo la segunda pestaña (24) coaxial con la primera pestaña (22), y teniendo de una pared (24a) cónica prevista en el primer lado de la misma, enfrentándose la pared cónica (24a) con la pared cónica (22a) de la primera pestaña (22) para formar una ranura (25) de recepción de correa de transmisión, alrededor de la cual se arrolla parcialmente una correa (20) de transmisión, siendo la segunda pestaña (24) axialmente móvil con relación a la primera pestaña (22) entre una posición distal y una posición proximal, siendo la ranura (25) de recepción de correa de transmisión más ancha que la correa detransmisión (20) cuando la segunda pestaña (24) se encuentra en posición distal, con lo que no existe contacto entre la pared (24a) cónica de la segunda pestaña (24) y el lado correspondiente de la correa (20) de transmisión cuando la segunda pestaña (24) está en posición distal; un primer medio de conexión de la primera pestaña (22) con el eje (16) motriz, en relación de enganche de transmisión de par motor; un segundo medio de conexión de la segunda pestaña (24) con el eje (16) motriz, en relación de enganche de transmisión de par motor; un tercer medio para la generación de una primera fuerza que empuja a la segunda pestaña (24) a moverse hacia la primera pestaña (22), actuando el tercer medio en respuesta a la velocidad de giro de la polea (12) motriz, y un cuarto medio para la generación de una segunda fuerza que empuja a la segunda pestaña (24) a moverse hacia fuera de la primera pestaña (22); estando la polea (12) motriz caracterizada porque el cuarto medio comprende al menos un muelle (30) de torsión que tiene al menos una porción (30a) arrollada y un brazo de palanca (30b), estando el brazo de palanca (30b) en relación de enganche deslizante con una rampa (50) curvada en forma convexa correspondiente, estando la porción (30a) arrollada conectada a una de entre la segunda pestaña (24) y la placa (32) extrema, y estando prevista la rampa (50) curvada convexamente en la otra de ellas, con lo que el cuarto medio genera la segunda fuerza con magnitud máxima cuando la segunda pestaña (24) está sustancialmente en posición distal, y con magnitud mínima cuando la segunda pestaña (24) está sustancialmente en posición proximal.
