Abstract
(DE)
Die Erfindung betrifft ein Antriebssystem (1) sowie ein Verfahren zum Steuern desselben. Das Antriebssystem (1) weist einen ersten Le istungs zweig und einen zweiten Leistungszweig (4) auf. Der erste Le istungs zweig weist eine stufenlos verstellbare Getriebeeinheit (3) auf. Der erste Leistungszweig und der zweite Le istungs zweig (4) sind über ein Summiergetriebe (25) miteinander verbunden. Das Summiergetriebe (25) weist ein erstes, ein zweites und ein drittes Getriebeelement (19, 20, 21) auf. Mit dem ersten Getriebeelement (19) ist eine Ausgangswelle (9) der stufenlos verstellbaren Getriebeeinheit (3) drehfest verbunden. Das zweite Getriebeelement (20) ist mit der Ausgangswelle (9) des ersten Leistungszweigs verbindbar. Das dritte Getriebeelement (21) ist mit einem mechanischen Getriebezweig des zweiten Leistungszweigs (4) drehfest verbunden.

The invention relates to a drive system (1) and to a method for controlling the same. The drive system (1) comprises a first power branch and a second power branch (4). The first power branch comprises a continuously variable transmission unit (3). The first power branch and the second power branch (4) are connected by means of a summation gear (25). The summation gear (25) comprises a first, a second, and a third gear element (19, 20, 21). An output shaft (9) of the continuously variable transmission unit (3) is rotationally fixed to the first gear element (19). The second drive element (20) can be connected to the output shaft (9) of the first power branch. The third gear element (21) is rotationally fixed to a mechanical transmission branch of the second power branch (4).

L'invention concerne un système d'entraînement (1) ainsi qu'un procédé de commande de celui-ci. Le système d'entraînement (1) présente une première branche de puissance et une deuxième branche de puissance (4). La première branche de puissance présente une unité de transmission à variation continue (3). La première branche de puissance et la deuxième branche de puissance (4) sont reliées l'une à l'autre par une transmission totalisatrice (25). La transmission totalisatrice (25) présente un premier, un deuxième et un troisième élément de transmission (19, 20, 21). Au premier élément de transmission (19) est relié solidaire en rotation un arbre de sortie (9) de la transmission à variation continue (3). Le deuxième élément de transmission (20) peut être relié à l'arbre de sortie (9) de la première branche de puissance. Le troisième élément de transmission (21) est relié solidaire en rotation à une branche de transmission mécanique de la deuxième branche de puissance (4).
