Abstract

Perfeccionamientos en las cajas de engranajes para cambio de velocidades para tractores agrícolas y vehículos similares, del tipo que comprenden una caja alargada, un eje de entrada montado giratorio en la caja y que se extiende longitudinalmente a través de la misma sobresaliendo por sus extremos opuestos, cuyos extremos sobresalientes del eje de entrada reciben respectivamente accionamiento de un motor del vehículo y constituyen una toma de fuerza, un eje de salida montado giratorio en la caja paralelo al eje de entrada y sobresaliente de la caja en el extremo correspondiente a la toma de fuerza, medios de reducción accionables por dicho eje de entrada y accionables selectivamente para proporcionar una de una pluralidad de relaciones de reducción, y una etapa de engranaje mecánica final que establece una conexión entre los medios de reducción y el eje de salida.
