Abstract

L’invention concerne un dispositif de changement de vitesse (100) pour engin de mobilité ledit dispositif présentant une pluralité de rapports entre un premier rapport dit rapport n°1 et un rapport supérieur, ledit dispositif de changement de vitesse comportant une série de pignons d’entrée (20, Fr1 à Frk) agencés pour tourner librement autour d’un arbre de sélection ( 200 ) d’ axe X2 , ledit arbre de sélection logeant une vis sans fin (132 ) et une navette (155) une série de pignons de sortie (30, F1 à Fk) d’axe X3, solidaires en rotation d’un arbre creux (230)un actionneur de changement de vitesse (150) agencé pour déplacer la navette (155) le long de la vis sans fin (132) entre une pluralité de positions et engager un rapport sélectionné. L’invention concerne également un engin de mobilité comportant un tel dispositif. Figure à publier avec l’abrégé : 3aThe invention relates to a gearshift device (100) for a mobility vehicle, said device having a plurality of ratios between a first gear called gear No. 1 and a higher gear, said gearshift device comprising a series of pinions of input (20, Fr1 to Frk) arranged to rotate freely around a selection shaft (200) of axis X2, said selection shaft housing a worm (132) and a shuttle (155) a series of pinions output (30, F1 to Fk) axis X3, integral in rotation with a hollow shaft (230) a gear change actuator (150) arranged to move the shuttle (155) along the endless screw ( 132) between a plurality of positions and engage a selected gear. The invention also relates to a mobility device comprising such a device. Figure to be published with abstract: 3a
