Abstract

See full text

The present invention relates to a device (100) for supplying fluid to an electric drive train for a motor vehicle, preferably for cooling and lubricating a transmission (50) and/or for supplying oil to an electric motor of the electric drive train. The device (100) comprises a main pump (10) configured as a hydraulic fixed displacement pump for delivering fluid from a fluid reservoir (40) to the electric drive train. The apparatus (100) further comprises at least one auxiliary pump (20) configured as a hydraulic fixed displacement pump. The main pump (10) and the auxiliary pump (20) are mechanically driven by the transmission (50) of the electric drive train in such a way that a fixed transmission ratio exists between a pumping rotation speed of the main pump (10) and a pumping rotation speed of the auxiliary pump (20), wherein the auxiliary pump (20) can be selectively connected by means of a controllable actuating device (30) for supplying fluid to the electric drive train.
