Zusammenfassung:The invention relates to a powertrain (12) for a motor vehicle (10), comprising a drive motor (14) for providing drive power, a transmission arrangement (16) for setting up a transmission ratio between the drive motor (14) and drive gears (VL, VR, HL, HR), and a hydraulic arrangement (40) for actuating components of the transmission arrangement (16). The hydraulic arrangement (40) has a main pump (42) which is connected to a hydraulic load section (48), and the hydraulic arrangement (40) has a secondary pump (66) which is driven by a secondary pump electric motor (68) if necessary and is connected to the load section (48). The secondary pump (66) is connected to or can be connected to a power branching device (26) for variably distributing drive power.
