Title (EN) DIFFERENTIAL TRANSMISSION DRIVE UNIT
(FR) UNITE D"ENTRAINEMENT A TRANSMISSION DIFFERENTIELLE
Abstract: front page image
(EN)A power splitting differential transmission unit (10) by which input power is transmitted in a controlled manner to one or both of two differential output shafts (24, 26) at continuously variable output/input speed ratios. The unit includes an integrated pair of continuously variable transmission units (70, 72) by which the output/input speed ratio for each output shaft may be adjusted synchronuously for driving both output shafts at equal speeds within the speed ratio range of the unit, for varying the output/input speed ratio for each output shaft (24, 26) independently or for simultaneously increasing the output/input speed ratio with respect to one output shaft (24, 26) while decreasing the same ratio with respect to the other (26, or 24) of the two shafts.
(FR)Une unite de transmission differentielle a partage d"energie (10) permet de transmettre l"energie d"entree de maniere controlee a l"un des deux ou aux deux arbres de sortie differentielle (24, 26) a des rapports de vitesse sortie/entree variables en permanence. L"unite comprend une paire integree d"unites de transmission continuellement variable (70, 72) qui permettent de regler de maniere synchrone le rapport de vitesse sortie/entree pour chaque arbre de sortie de maniere a entrainer les deux arbres a des vitesses egales dans la plage des rapports de vitesse de l"unite et a modifier le rapport de vitesse sortie/entree pour chaque arbre de sortie (24, 26) independamment ou de maniere a augmenter simultanement le rapport des vitesses sortie/entree par rapport a l"un des deux arbres de sortie (24, 26) tout en diminuant le meme rapport pour l"autre arbre (26 ou 24).
