HEAVY DUTY DRIVE VEHICLE, ESPECIALLY A HEAVY DUTY TRAIN VEHICLE OR HEAVY DUTY PUSHING VEHICLE

摘要

The invention relates to a heavy-duty drive vehicle to which at least one towed or pushed vehicle (20) can be mechanically coupled, the heavy-duty drive vehicle (10) having a drive motor (13) which provides a total drive power and via a transmission (14) is connected to at least one driven wheel arrangement (12a-12c) of the heavy-duty drive vehicle (10), a first portion of the instantaneous total drive power of the drive motor (13) as a first drive power via a travel gear (15) of at least one wheel arrangement (12a- 12c) of the heavy-duty drive vehicle (10). According to the invention, it is provided that the drive motor (13) of the heavy-duty drive vehicle (10) has a generator (30; 30 ') for generating a second with a second portion of the total drive power Drive power drives, so that the current total drive power of the drive motor (13) is constant or variable on the first and the second drive The second drive power is determined by that portion of the current total drive power which, due to a lack of traction of the at least one wheel arrangement (12a-12c) driven by the travel gear (15), cannot be converted into propulsion of the heavy-duty drive vehicle (10) , and that this second drive power can be directed to at least one wheel arrangement (22b, 22c) of the further vehicle (20) mechanically connected to the heavy-duty drive vehicle (10).
