Zusammenfassung:	PROBLEM TO BE SOLVED: To improve fuel efficiency concerning an electric power train for a working machine. SOLUTION: An electric power train 12 of a crawler type working machine includes: an engine 44 configured to provide mechanical energy; a generator 46 coupled to the engine 44; at least one electric motor 48 coupled to the generator 46, and configured to supply torque to a plurality of driving members 34, 36; at least one power electronics unit 50, 60; and an electric energy accumulation system 56 configured to collect energy from at least one electric motor 48 during the deceleration of the working machine. The driving members 34, 36 are configured as gear deceleration ultimate driving device which transmits torque via a differential steering unit 68 to the crawler of the working machine.
