Abstract

Dispositif à transmission mécanique à planétaire et à organes d'enclenchement à manoeuvre hydraulique destinés à la mise en prise sélectionnée des éléments de la transmission, ce dispositif comprenant un distributeur de commande qui est sous la dépendance de la position d'un levier de sélection de vitesses se manoeuvrant à la main. Un distributeur d'enclenchement 5 qui est sous la dépendance de la position de la pédale d'accélération 40 et qui est monté dans la canalisation 4, 6 d'alimentation en fluide sous pression de commande provoque le débrayage au moins lorsque le véhicule est à l'arrêt et que le levier de sélection de vitesses est à la position de marche sur route D et lorsque la pédale d'accélération n'est pas actionnée. Application aux boîtes à vitesses automatiques des voitures automobiles pour éviter le rampage.
