Abstract

Perfeccionamientos en las transmisiones de tipo mecánico y de variación continua de velocidad, particularmente para cultivadoras, tractores y máquinas similares accionadas a motor, caracterizados porque la transmisión comprende un primer árbol acoplado directamente a un árbol motor o cigüeñal de motor y que acciona un segundo árbol por medio de un grupo motor de reducción variable continua, estando conectados dichos árboles primero y segundo cinemáticamente a un sistema diferencial acoplado a un tercer árbol, que gira a una velocidad proporcional a la diferencia de velocidad rotativa entre dichos árboles primero y segundo, accionando dicho tercer árbol la ruedas motrices de la máquina a través de una conexión cinemática, y accionando dicho primer árbol una toma de fuerza a través de un tren cinemático.
