Abstract
The disclosure relates to a pump assembly for a vehicle having an internal combustion engine with or without transmission or electric motor with transmission or for an oil supply having a double-pipe pump, wherein the two pipes are separated from each other and a second pipe can be connected to a first pipe, wherein the pump has at least one input drive point for an electric machine and also for a drive motor, including, for example, via a gearbox.
Claims19
A pump assembly for a vehicle with a drive unit, comprising;
- a singular double flow pump, the two flows being separate from one another, and it being possible for a second flow to be added to a first flow, the pump having a first input point for an electric machine and a second input point for the drive unit, wherein the electric machine is dimensioned for driving the pump with the first flow and runs at a single flow rotational speed above a highest rotational speed of the drive unit;
- and
- a switching valve attached between the first flow and the second flow,
- wherein when the switching valve is opened, the rotational speed of the electric machine is set to the single flow rotational speed above the highest rotational speed of the drive unit, and
- when the switching valve is closed, the rotational speed of the electric machine is reduced to zero or to a rotational speed lower than a rotational speed of the drive unit.

A pump assembly for a vehicle with a drive unit, comprising:
- a double flow pump, the two flows being separate from one another, and it being possible for a second flow to be added to a first flow, the pump having a first input point for an electric machine and a second input point for the drive unit, wherein both of the drive unit and the electric machine drive the pump in the same rotational direction, wherein the electric machine is dimensioned for driving the pump with the first flow and runs at a single flow rotational speed above a highest rotational speed of the drive unit;
- and
- a switching valve attached between the first flow and the second flow,
- wherein when the switching valve is opened, the rotational speed of the electric machine is set to the single flow rotational speed above the highest rotational speed of the drive unit, and
- when the switching valve is closed, the rotational speed of the electric machine is reduced to zero or to a rotational speed lower than a rotational speed of the drive unit.
