Abstract

Perfeccionamientos en transmisiones, en particular para vehículos a motor, dotada de una correa de transmisión en V variable indefinidamente que posee una polea primaria y otra secundaria, dotada cada una respectivamente de un cilindro de actuación primaria y secundaria para el desplazamiento axial de al menos uno de los discos cónicos, dotada además de una unidad de transmisión hidrodinámica, caracterizados porque se han previsto medios para trabar la unida de transmisión hidrodinámica que son actuables en función de la presión del fluido en el cilindro de actuación primaria.
