Abstract
El presente invento controla la circulación de fluido tal como aire comprimido para el cambio entre relaciones de una caja de velocidades, en respuesta a la presión del fluido hidráulico en el sistema de control del embrague. Así, el cambio de una caja de transmisión entre las relaciones baja y alta es permitido solamente cuando las condiciones de embrague del vehículo, particularmente la presión del fluido hidráulico del embrague, alcanzan un valor predeterminado. Utilizando el control de este invento, el conductor puede preseleccionar la relación de cambio, por ejemplo, de baja a alta, pero puede cambiar entre relaciones solamente si el fluido hidráulico del embrague alcanza una presión previamente ajustada, tal como aproximadamente 12,6 kg/cm2 o superior.
