  • Method for operating a drive train for a working machine, drive train for a working machine, and working machine
    Patent number: 12624528
    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.

  • Traction drive system and method for operating a traction drive system
    Patent number: 12460718
    Abstract: A traction drive system for a work machine, including at least one electric motor, a transmission, and a controller. The controller is configured to select a gear ratio of the transmission depending on a change to be expected in a motor output of the at least one electric motor. The change to be expected in the motor output is conditional on a change in the gear ratio of the transmission. The change to be expected in the motor output is determined on the basis of at least one operating parameter of the work machine.

  • METHOD FOR ADAPTIVELY DETERMINING A SHIFTING POINT OF A MULTI-GEAR POWERSHIFT TRANSMISSION OF A WORKING MACHINE, CONTROL UNIT, COMPUTER PROGRAM PRODUCT AND WORKING MACHINE
    Publication number: 20250109789
    Abstract: A method for adaptively setting a shift point of a multi-speed powershift transmission of a working machine that includes an electric drive system and a control device. The electric drive system has a battery and an electric motor. The multi-speed powershift transmission is connected to the electric drive system. The control device is connected to the electric drive system and the multi-speed powershift transmission in a signal-effective manner. The method includes specifying a tractive force which must be present during shifting operations of the multi-speed powershift transmission, determining a state variable of the electric drive system, and determining based on the state variable and the specified tractive force, a driving speed at which the specified tractive force is essentially maintained during the shifting operation. The method includes setting the shift point at the determined driving speed and carrying out the shifting operation at the shift point.

  • Drive axle for an electrically driven work machine
    Patent number: 11518191
    Abstract: A drive axle for a work machine for driving wheels that are coupled to the drive axle. The drive axle includes a spur gear stage with an input shaft. A differential gear unit couples to the spur gear stage and to the wheels via wheel drive shafts. The drive axle further includes a reduction gear unit with an output element couples to the input shaft of the spur gear stage—and an input element which couples to an output shaft of an electric drive machine.
