Abstract

Circuito de control para un sistema de transmisión de vehículos que tiene una caja de cambios con relaciones múltiples, cuyas relaciones individuales son seleccionadas por excitación de un respectivo solenoide entre una pluralidad de solenoides, incluyendo el circuito de control de interruptor selector accionable manualmente que tiene una pluralidad de posiciones de selección en una de las cuales será excitado el correspondiente solenoide, teniendo también el interruptor selector una posición neutra en la que no es excitado ninguno de los solenoides, un primer transistor que tiene su recorrido colector-emisor conectado en serie con dicho interruptor, medios de mando de base para dicho primer transistor, medios de temporización accionables cuando se conecta el circuito a una fuente de corriente eléctrica, para encender dicho segundo transistor y posteriormente apagarlo, y un circuito de mando de base para dicho segundo transistor que en caso de que se encuentre dicho interruptor selector en una posición de selección, cuando es conectado el circuito de control a la fuente de alimentación, proporciona el mando de base para dicho segundo transistor y lo mantiene en un estado conductor independientemente del medio de temporización.
