Beschreibung
Zusammenfassung:	A hybrid oil pump for a vehicle with an engine. The hybrid oil pump includes an oil pump unit with a pump shaft, a mechanical drive to drive the oil pump unit in a mechanical driving mode, an electrical drive to drive the oil pump unit in an electrical driving mode, a switchable clutch arranged between the motor shaft and the pump shaft, and a freewheel clutch to automatically couple the mechanical drive with the pump shaft when a rotational speed of the mechanical drive is higher than a rotational speed of the electric motor. The oil pump unit pumps pressurized oil to a vehicle component. The mechanical drive is mechanically connected to and driven by the engine. The electrical drive includes an electric motor and a motor shaft. The switchable clutch mechanically disengages the electrical drive from the oil pump unit in the mechanical driving mode.
