Work machine, in particular dump truck or truck

A work machine, in particular in the form of a dump truck or truck, having a diesel electric traction drive, comprising

• pairs of front and rear wheels (14, 16),
• electric motors (80) arranged to drive the rear wheels (16),
• a skip (18) pivotally connected to a frame of the truck,
• an internal combustion engine (40),
• an alternator (60) connected to the electric motors (80) and driven by the internal combustion engine (40),
• an excitation winding (62) integrated in the alternator (60),
• an excitation circuit (64) supplying the excitation winding (62) with current,
• a supply line (66) connected to the excitation circuit (64) for controlling excitation voltage,
• a voltage supply (68) connected to the supply line (66),
• a manually-actuatable breaker switch (90, 92, 94, 96) arranged to interrupt the excitation circuit (64),
• power electronics (100) interconnecting the alternator (60) and electric motors (80), with the supply line (66) and excitation circuit (64) also connected to one another through the power electronics (100),
• a switch cabinet for low voltage switches interconnecting the voltage supply (68) and excitation circuit (64),
• a pump transfer case (50) mounted directly at the internal combustion engine (40), and
• secondary drives (51, 52) mounted to the pump transfer case (50) for hydraulically driving secondary consumers of power.
