  • Propulsion drive system for mobile machine
    Patent number: 11607941
    Abstract: A propulsion drive system for a mobile machine includes an electric motor having a first range, in which a torque is constant as a rotational speed rises, and a second range, in which a power is constant as the rotational speed rises. The propulsion drive system further includes a transmission operatively connected mechanically to the electric motor. The propulsion drive system is configured to be transferred, via the transmission, from a state for relatively low driving speeds into a state for relatively high driving speeds of the mobile machine. The electric motor and the transmission are adapted to one another in such a way that the electric motor can be operated in the state for relatively low driving speeds exclusively in the first and second range.

  • 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.

  • METHOD FOR OPERATING A DRIVE TRAIN FOR A WORKING MACHINE, DRIVE TRAIN FOR A WORKING MACHINE, AND WORKING MACHINE
    Publication number: 20220186468
    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.
