Abstract
(DE)
Die Erfindung betrifft ein Verfahren zum Betreiben eines Antriebsstrangs (1) für eine Arbeitsmaschine, wobei ein erster Elektromotor (2) über eine erste Getriebeanordnung (4) einen Arbeitsantrieb (6) der Arbeitsmaschine antreibt, wobei ein zweiter Elektromotor (3) über eine zweite Getriebeanordnung (5) einen Fahrantrieb (7) der Arbeitsmaschine antreibt und wobei während eines Schaltvorgangs der zweiten Getriebeanordnung (5) aus einer niedrigeren Gangstufe in eine höhere Gangstufe eine Drehzahlreduzierung des zweiten Elektromotors (3) erfolgt. Das erfindungsgemäße Verfahren zeichnet sich dadurch aus, dass während des Schaltvorgangs über eine erste Kupplung (8) eine Triebverbindung zwischen dem ersten Elektromotor (2) und der zweiten Getriebeanordnung (5) hergestellt wird (22), so dass der erste Elektromotor (2) während des Schaltvorgangs den Fahrantrieb (7) antreibt (24, 25, 27, 28). Die Erfindung betrifft weiterhin einen entsprechenden Antriebsstrang (1) und eine Arbeitsmaschine.
(EN)
The invention relates to a method for operating a drivetrain (1) for a work machine, wherein a first electric motor (2) drives a work drive (6) of the work machine via a first transmission arrangement (4), wherein a second electric motor (3) drives a traction drive (7) of the work machine via a second transmission arrangement (5), and wherein, during a shift process of the second transmission arrangement (5) from a relatively low gear ratio stage to a relatively high gear ratio stage, the rotational speed of the second electric motor (3) is reduced. The method according to the invention is distinguished by the fact that, during the shift process, a driving connection is produced (22) between the first electric motor (2) and the second transmission arrangement (5) by means of a first clutch (8), such that, during the shift process, the first electric motor (2) drives (24, 25, 27, 28) the traction drive (7). The invention furthermore relates to a corresponding drivetrain (1) and to a work machine.
(FR)
La présente invention concerne un procédé d'actionnement d'une chaîne cinématique (1) pour un engin de chantier, un premier moteur électrique (2) entraînant un entraînement de travail (6) de l'engin de chantier par l'intermédiaire d'un premier agencement de transmission (4), un second moteur électrique (3) entraînant un entraînement de traction (7) de l'engin de chantier par l'intermédiaire d'un second agencement de transmission (5), et pendant un processus de changement de vitesse du second agencement de transmission (5) d'un étage de rapport de vitesse relativement faible à un étage de rapport de vitesse relativement élevé, la vitesse de rotation du second moteur électrique (3) est réduite. Le procédé selon l'invention se caractérise en ce que, pendant le processus de changement de vitesse, un raccordement d'entraînement est produit (22) entre le premier moteur électrique (2) et le second agencement de transmission (5) au moyen d'un premier embrayage (8), de sorte que, pendant le processus de changement de vitesse, le premier moteur électrique (2) entraîne (24, 25, 27, 28) l'entraînement de traction (7). La présente invention concerne en outre une chaîne cinématique (1) correspondante et un engin de chantier.
