METHOD FOR OPERATING A DRIVETRAIN FOR A WORK MACHINE, DRIVETRAIN FOR A WORK MACHINE, AND WORK MACHINE

摘要

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.
