Abrégé

An electric axle arrangement for a drive train of a motor vehicle includes a drivable axle that is or can be drivingly connected to an electric machine, a coolant sump with liquid coolant, and an elevated tank, wherein the liquid coolant is delivered from the coolant sump into the elevated tank via a gearwheel attached to the axle. The elevated tank is connected to a cooling system for cooling the electric machine via a switchable valve. When the valve is closed during an idling operation, the return flow of the coolant into the coolant sump via the cooling system is prevented, and drag losses in the idling operation of the electric machine are reduced, because more coolant collects in the elevated tank and the gearwheel therefore encounters a reduced quantity of coolant in the sump.
