Abstract
L'invention concerne une boîte de vitesses simple. La boîte 10 comporte un arbre primaire 12 portant un pignon 14 constamment en prise avec un pignon 24 calé sur un arbre intermédiaire 16 auquel sont fixés des pignons 26 à 40 constamment en prise avec des pignons 42 à 54 qui entourent un arbre secondaire 18 auquell ils peuvent être sélectivement embrayés par des organes d'embrayage 56 à 62 pour changer les rapports de vitesse entre l'arbre primaire et l'arbre secondaire. L'arbre intermédiaire est en deux parties 20, 22 accouplées au moyen d'un engrenage de renvoi 70 en prise avec des pignons 32, 34 dont l'un est porté par la première partie et l'autre par la seconde partie pour assurer une démultiplication entre les deux parties. La boîte a une gamme de rapports étendue et un nombre élevé de rapports tandis que la distance entre les axes des arbres 16 et 8 est minimale.
