Abstract

La presente invención se refiere a aparato de control de toma de fuerza para una transmisión, que incluye un accionador sensible a la presión de fluido para engranar y desengranar selectivamente un mecanismo de toma de fuerza, una válvula de control para la aplicación e interrupción selectiva de presión de fluido al accionador, teniendo la transmisión mecanismos de escala de velocidades, cambiables mediante el movimiento de una varilla selectora de la escala de velocidades, entre una escala de velocidades del mecanismo de alta velocidad en donde la transmisión es operable en una primera pluralidad de relación de engranaje y una escala de velocidades del mecanismo de baja velocidad en donde la transmisión es operable en una segunda pluralidad de relación de engranaje, un control operado por fluído para el movimiento de la varilla selectora de la escala de velocidades, entre una primera posición que engrana la escala de velocidades del mecanismo de alta velocidad y una segunda posición que engrana la escala de velocidades del mecanismo de baja velocidad, caracterizado el aparato de control de toma de fuerza, por primeros medios que dan respuesta a la válvula de control aplicando presión de fluido al accionador para engranar el mecanismo de toma de fuerza, inhibiendo al control operado por fluído desde el movimiento de la varilla selectora de la escala de velocidades ya sea a la primera o a la segunda posiciones y segundos medios, para dar respuesta a la válvula de control aplicando presión de fluido al accionador para engranar el mecanismo de toma de fuerza, para la colocación de la varilla selectora de la escala de velocidades en una posición intermedia entre la primera y segunda posiciones con lo cual la transmisión se mantiene en neutral cuando la presión fluente se aplica al accionador del mecanismo de toma de fuerza mencionado.
