Abstract
(EN)
A vehicle transmission system includes an input shaft (2) connected to a differential mechanism, which has two output shafts (12, 20). The two output shafts carry first and second coaxially mounted sun wheels (10, 12), respectively, of an epicyclic gear system which mesh with first and second sets of planet wheels (P1, P2), respectively, which mesh with first and second annulus wheels (A1, A2), respectively. Each planet wheel (P1, P2) is mounted to rotate independently about a respective planet shaft (22) and the planet shafts are connected to a common carrier (24), which is rotatably mounted coaxially with the first and second sun wheels. The first and second annulus wheels (A1, A2) are connected together. The carrier (24) is connected to selectively operable speed changing means (28) arranged to increase or decrease the speed of rotation of the carrier about its axis.
(FR)
La présente invention concerne un système de transmission de véhicule comprenant un arbre d'entrée (2) relié à un mécanisme différentiel qui présente deux arbres de sortie (12, 20). Les deux arbres de sortie portent une première et une seconde roue solaire (10, 12) montées de façon coaxiale appartenant respectivement à un système d'engrenage épicyclique qui s'engrène avec un premier et une second ensemble de roues planétaires (P1, P2) qui s'engrènent respectivement avec une première et une seconde roue annulaire (A1, A2). Chaque roue planétaire (P1, P2) est montée pour tourner indépendamment autour d'un arbre planétaire respectif (22) et les arbres planétaires sont reliés à un support commun (24) qui est monté rotatif de façon coaxiale avec la première et la seconde roue solaire. La première et la seconde roue annulaire (A1, A2) sont reliées. Le support (24) est relié à un système de changement de vitesse (28) à fonctionnement sélectif conçu pour augmenter ou réduire la vitesse de rotation du support autour de son axe.
