Abstract
The disclosure relates to a method for operating a drive train for a working machine, in which a working drive of the working machine is driven by a first electric motor via a first gear arrangement, a travel drive of the working machine is driven by a second electric motor via a second gear arrangement and, in a shifting procedure of the second gear arrangement, the rotational speed of the second electric motor is synchronised and the temperature of said second electric motor is recorded. In the disclosed method, the rotational speed is synchronised by supplying current to the second electric motor, 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. The disclosure further relates to a corresponding drive train and to a working machine.
