Abstract
La présente invention concerne un dispositif de changement de vitesses pour une boîte de vitesses d'un véhicule, comprenant un arbre (1), un pignon de vitesse (2), un élément à complémentarité de forme (3) et un élément de changement de vitesses (10). Selon l'invention, l'élément de changement de vitesses présente un élément en forme de douille (11) pouvant coulisser axialement, un coulissement axial de cet élément en forme de douille provoquant un déplacement axial de l'élément à complémentarité de forme le long de l'axe longitudinal (1.1) de l'arbre, un couple pouvant être transmis entre l'élément à complémentarité de forme et l'élément en forme de douille et/ou entre l'arbre et l'élément en forme de douille. Toujours selon l'invention, l'élément de changement de vitesses présente un actionneur (12) qui, à l'état activé, est en liaison fonctionnelle avec l'élément en forme de douille et qui, à l'état activé, provoque un déplacement axial de l'élément en forme de douille le long de l'axe longitudinal de l'arbre. L'invention concerne également une boîte de vitesses.
