Method for operating a drive train of a working machine, drive train for a working machine and working machine

摘要

The invention relates to a method for operating a drive train (1) of a working machine, wherein the drive train (1) comprises a work drive and a travel drive, wherein the travel drive is driven according to a performance requirement of the travel drive by an electric travel motor (3), wherein the work drive is driven by an electric work motor (2) according to a power requirement of the work drive and wherein a temperature (T) of the driving motor (3) and a temperature (T) of the work motor (2) are detected. The method according to the invention is characterized by:that a temperature gradient (ΔT) of the driving engine (3) is determined from a temperature gradient (20) of the driving engine (3); and/or that a temperature gradient (ΔT) of the working motor (2) is determined from a temperature gradient (20) of the working motor (2) and that a power consumption of the driving motor (3) is limited according to the temperature (T) of the driving motor (3) and the temperature gradient (ΔT) of the driving motor (3)is and/or the temperature (T) of the working motor (2) and the temperature gradient (ΔT) of the working motor (2) limit the power consumption of the working motor (2). The invention further relates to a corresponding drive train (1) and a working machine.
