Abstract

Sistema de regulación para una transmisión con dos pares de poleas cónicas (6 - 8, 13 -11) acopladas entre sí por un medio de transmisión sinfín (14) y ajustables con relación al radio de recorrido de las mismas, en el cual al menos una polea (8-13) de cada par (6 - 8, 13 - 11) está acoplada con al menos un actuador hidráulico (7, 12) que determina la posición axial de la polea, y en el cual la abertura de conexión (15, 17) de cada actuador (7, 12) está conectada con una de las dos aberturas (23, 20) de una primera motobomba hidráulica (19) regulable en cuatro cuadrantes y comprendiendo además una conexión entre una reserva de medio hidráulico y al menos uno (12) de los actuadores (7, 12), incluyendo dicha conexión un segundo órgano de bombeo hidráulico (25), caracterizado porque dicho segundo órgano de bombeo hidráulico (25) es una segunda motobomba, regulable en dos cuadrantes, estando conectado el orificio o abertura de salida (24) dedicha segunda motobomba (25), durante el funcionamiento de la misma, con la abertura de admisión (17) de uno (12) de los actuadores (7, 12).
