Abstract

Perfeccionamientos introducidos en un mecanismo de transmisión para vehículo automóvil, que comprende un árbol motor, un árbol receptor equipado con un dispositivo de cambio de velocidad, un árbol de salida enganchado a las ruedas, un dispositivo de acoplamiento que une el árbol motor y el árbol receptor, un dispositivo de inversión del sentido de marcha que une el árbol receptor al árbol de salida, medios de accionamiento de un freno del árbol receptor y medios de selección manual de las posiciones de embrague "Marcha adelante" o "Marcha atrás", y de las posiciones "Punto muerto" y "Freno de estacionamiento" del dispositivo de inversión, constituido por un sistema articulado que comprende una palanca de mando manual de las posiciones citadas, caracterizados porque los medios de accionamiento cintados están constituidos por un circuito de alimentación del freno en fluido bajo presión, sobre el que está dispuesta una electroválvula, que interrumpe habitualmente el citado circuito cuando no está excitada, y cuyo circuito eléctrico de excitación comprende un primer interruptor habitualmente abierto, un primer órgano de cierre del citado primer interruptor, adecuado para ser accionado por la citada palanca cuando es maniobrado en el sentido del establecimiento de un enlace, al nivel del dispositivo de inversión, entre los árboles receptor y de salida citados, y porque el citado sistema articulado comprende un dispositivo elástico, susceptible de ser comprimido, cuando el esfuerzo de maniobras aplicado a la palanca citada alcanza un valor predeterminado.
