Abstract[English]
The invention relates to an automatic gear transmission system for a vehicle including a motor capable of rotating an input shaft (1), the system comprising a first short-gear clutch device and a second long-gear clutch device according to the speed of rotation of the output shaft (1), the clutch devices comprising a common hub (9), or separate hubs, which is mechanically connected to the output shaft (1) and which includes: - drive means for transmitting the movement of the input shaft to the output shaft; - disengageable coupling means, which couple the drive means to the output shaft; - at least one control device capable of controlling the engagement and disengagement of the clutch devices, in order to switch from one gear to the other; and - a one-way coupling means (6) between the drive means of the first short-gear clutch device and the output shaft (1).[French]
L' invention concerne un système de transmission automatique de vitesse pour un véhicule comportant un moteur apte à actionner en rotation un arbre d'entrée (1), ledit système comprenant un premier dispositif d'embrayage de rapport court et un deuxième dispositif d'embrayage de rapport long selon le régime de l'arbre de sortie (1), les dispositifs d'embrayage comprenant un moyeu commun (9), ou des moyens distincts, qui est lié mécaniquement à l'arbre de sortie (1) et qui comporte - des moyens d'entraînement pour transmettre le mouvement de l'arbre d'entrée à l'arbre de sortie, - des moyens d'accouplement débrayable, qui couplent le moyen d'entrainement à l'arbre de sortie, - au moins un dispositif de commande apte à commander l'engagement et le désengagement des dispositifs d'embrayage, pour passer d'un rapport à l'autre - un moyen d'accouplement unidirectionnel (6) entre les moyens d'entraînement du premier dispositif d'embrayage de rapport court et l'arbre de sortie (1).
