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.
A method for operating a drive train for a working machine, wherein a working drive of the working machine is driven by a first electric motor via a first transmission arrangement, wherein a traction drive of the working machine is driven by a second electric motor via a second transmission arrangement, wherein, during a shifting operation of the second transmission arrangement, a speed synchronization of the second electric motor is carried out, and wherein a temperature of the second electric motor is detected, wherein the speed synchronization is carried out by energization of the second electric motor, and in that, if a limit temperature is exceeded, at least one measure for relieving the thermal load of the second electric motor is carried out.
A drive train for a working machine, wherein the drive train comprises a working drive having a first transmission arrangement and having a first electric motor, and a traction drive having a second transmission arrangement and having a second electric motor, wherein the working drive can be driven by the first electric motor via the first transmission arrangement and wherein the traction drive can be driven by the second electric motor via the second transmission arrangement, wherein a drive connection can be established between the working drive and the traction drive via a connecting clutch.
