Abstract

L'invention concerne un dispositif de mise au point pour une boîte de vitesse à changement de vitesse d'un véhicule, comprenant un axe du levier de commande de changement de vitesse (6) disposé dans un logement (2) pour boîte de vitesse, pouvant se déplacer de manière axiale et rotative, et qui présente un levier de vitesse (8) disposé sur le logement et conçu pour activer le changement de vitesse, ledit levier étant relié de manière cinématique à un levier manuel. Ledit dispositif comprend également une masse supplémentaire (14, 20) qui agit sur le levier de vitesse (8) et qui est disposée, de manière à pouvoir tourner, à l'intérieur du logement (2) de boîte de vitesse, relié à l'axe du levier de commande de changement de vitesse (6) au moyen d'un élément articulé (18), de sorte que le moment d'inertie de la masse de l'axe du levier de commande de changement de vitesse (6) est amélioré. Selon l'invention, le centre de gravité de la masse supplémentaire (14, 20) correspond sensiblement à l'axe de rotation (16, 22) de la masse supplémentaire (14, 20).
