Abstract

Dispositif de changement de vitesse pour boîte de vitesses avec dispositifs d'arrêt et de rappel pour la position de changement de vitesse et de porte d'un levier de changement de vitesse (2), dont les mouvements selon le schéma H ou HH sont transmis par l'organe de changement de vitesse à la boîte de vitesses et où la recherche des portes et/ou des rapports s'effectue par des crans à ressort de forces différentes, les crans à ressort (3) étant affectés à différents rapports et portes en fonction d'au moins un paramètre de marche du véhicule et, dans une configuration avantageuse, un rapport n'étant offert au conducteur qu'après sélection d'un mode de conduite orienté d'un côté performant ou économique. Cette offre se produit toujours lorsque le levier de changement de vitesse (2) est amené en position de point mort (45) et ne nécessite, pour rentrer un rapport, que le dépassement du seuil de force (4) agissant dans la direction du changement de vitesse. Si l'on doit rentre à partir de cette offre un rapport supérieur ou inférieur, il faut en outre surmonter les premières forces de sélection (31). Comme les rétrogradages ne sont admis que pour un rapport voisin, dans un cas exceptionnel pour un rapport supplémentaire, les changements de vitesse en haut s'effectuent également dans des rapports supérieurs après dépassement d'autres seuils de force dans la direction de sélection (32). L'offre de rapport pour le conducteur est réalisée par un dispositif à piston (7) agissant simplement et fonctionnant de par l'action d'un milieu sous pression, en liaison avec un axe de changement de vitesse (6) et une coulisse d'arrêt (62).
