Title (EN) GEARBOX WITH RADIAL COUPLING AND ELECTRONIC CONTROL
(FR) BOITE DE VITESSES A EMBRAYAGES RADIAUX ET CONTROLE ELECTRONIQUE
Abstract:
(EN) The gearbox is designed in a known manner to establish a relationship by suitable gear reduction between the number of revolutions per minute of a primary shaft (3) and the number of revolutions per minute of at least one secondary shaft (4). It comprises fixed gears (1-REV, 1-I, 1-II and 1-III) on the primary shaft (3) which engage at all times with the idler gears (2-REV, 2-I, 2-II and 2-III) on the secondary shaft (4), and coupling means for individually locking said idler gears in rotation on their shafts. According to the invention, said coupling means (52, 24a, 25a; 52, 24b, 25b) are located between said idler gears and their respective shafts. These coupling means are fixed on said shafts and act radially with respect to the axis of rotation of the said shafts.
(FR) La boîte de vitesse est adaptée, d'une manière connue en soi, à mettre en corrélation, par une démultiplication appropriée, le nombre de tours d'un arbre primaire (3) et le nombre de tours d'au moins un arbre secondaire (4) et elle comporte des pignons montés fixes (1-AR, 1-I, 1-II et 1-III) sur l'arbre primaire (3) qui engrènent de façon permanente des pignons montés fous (2-AR, 2-I, 2-II et 2-III) sur l'arbre secondaire (4), et des moyens d'accouplement adaptés à bloquer individuellement en rotation lesdits pignons montés fous sur leur arbre. Selon l'invention, lesdits moyens d'accouplement (52, 24a, 25a; 52, 24b, 25b) sont interposés entre lesdits pignons montés fous et leurs arbres respectifs, ces moyens d'accouplement étant montés fixes sur lesdits arbres et agissant radialement par rapport à l'axe de rotation dudit arbre.
