  • Work machine having a hydro-mechanical drive unit
    Patent number: 11975721
    Abstract: A mobile work machine has a drive unit for driving at least one drive element and/or a working element. The drive unit is hydromechanical drive unit with at least one internal combustion engine and hydraulic energy transmission unit with at least one hydraulic pump and a hydraulic motor. In normal operation, the motor shaft of the internal combustion engine rotates at a normal speed (n_0). Conversely, in a limit temperature operation in which a sensed actual operating temperature of the internal combustion engine or another part of the drive unit is higher than or equal to a target limit temperature (T_limit), an electrical control unit and/or electronic control unit controls the internal combustion engine in such a way that the motor shaft of the internal combustion engine rotates at a first speed (n_target) that is higher than the normal speed (n_0) of the motor shaft in normal operation.
