Method for operating a drive train for the variable-speed driving of a work machine and drive train

摘要

The invention relates to a method for operating a drive train for the variable-speed driving of a work machine. The invention further relates to the embodiment of a drive train. The method is characterized by the following steps: - Starting the electric drive machine (9) from standstill with emptied hydrodynamic speed / torque converter (2, 16, 22) until reaching a predefined, at least indirectly characterizing the operation of the drive machine (9) size , in particular the rated speed of these simultaneously to achieve the predefined, the operation of the prime mover (9) at least indirectly characterizing size, in particular the rated speed or offset after reaching this filling of the hydrodynamic speed / torque converter and driving the Turbinenrades- driving the third element of the Planetenradgetriebes at a speed which from a defined by the planetary gear superposition of the speed of the connected to the electric drive machine first element of the planetary gear and the speed of the at least indirectly ve with the turbine wheel rbundenen second element of the planetary gear results.
