Abstract

Dispositif de commande d'une transmission, destiné à provoquer automatiquement des changements de vitesse. Il comporte un détecteur électronique de vitesse et un élément de distribution qui change automatiquement le rapport de vitesse de la transmission afin de faire passer cette dernière d'une vitesse relativement élevée à une vitesse plus faible lorsque le véhicule avance sur le sol à une première vitesse prédéterminée Lorsque le véhicule reprend de la vitesse, l'élément de distribution fait repasser automatiquement la transmission du rapport de vitesse inférieur au rapport supérieur. Domaine d'application tracteur à benne chargeuse, engins de travaux publics, etc.
