The invention relates to a method for operating a drive train (1) for a working machine, in which a working drive (6) of the working machine is driven by a first electric motor (2) via a first gear arrangement (4), a travel drive (7) of the working machine is driven by a second electric motor (3) via a second gear arrangement (5) and, in a shifting procedure of the second gear arrangement (5), the rotational speed of the second electric motor (3) is synchronized and the temperature of the second electric motor (3) is recorded. The claimed method is characterized in that the rotational speed is synchronized by supplying current to the second electric motor (3), and in the event of a threshold temperature being exceeded, at least one measure is carried out to relieve the thermal load of the second electric motor (3). The invention further relates to a corresponding drive train (1) and to a working machine.

    本发明涉及一种操作用于工作机器的驱动系(1)的方法,其中工作机器的工作驱动器(6)由第一电动马达(2)经由第一齿轮布置(4)进行驱动,工作机器的行进驱动器(7)由第二电动马达(3)经由第二齿轮布置(5)进行驱动,并且在第二齿轮布置(5)的换挡过程中,同步第二电动马达(3)的旋转速度,并且记录所述第二电动马达(3)的温度。所要求保护方法的特征在于,通过对第二电动马达(3)供应电流来同步旋转速度,并且在超过阈值温度的情况下,执行至少一种措施来减轻第二电动马达(3)的热负载。本发明进一步涉及一种相应的驱动系(1)以及一种工作机器。
