- the inner shaft has by design a smaller diameter than the hollow shaft.
- the connection of the pump to the inner shaft provides, inter alia, the advantage that a relatively small pump with small friction radii can be used.
- the pump can be attached to a particularly advantageous from the hollow shaft end of the inner shaft. This provides the advantage that the pump requires only one shaft bushing, which means only one shaft seal.
- the inner shaft needs to be stored advantageously only at one point in or on the pump.
- a preferred embodiment of the pump drive is characterized in that the second drive means comprises an electric motor.
- the electric motor is preferably used to drive the pump via the hollow shaft, which in turn drives the inner shaft via the transmission, in particular via planet wheels and a planet carrier.

- the first drive device comprises an internal combustion engine or an electric motor.
- the internal combustion engine is, preferably with the interposition of a clutch, via the transmission drivingly connected to the inner shaft.
- the first drive device is, preferably non-rotatably connected to a drive wheel, for example a gear, which drives the ring gear directly or via a further drive element, for example a chain.
- a drive by the first drive means the torque required for driving the pump from the ring gear preferably via planetary gears on a planetary carrier and the associated inner shaft is transmitted.
- the second drive device can be connected or connected to the pump as an alternative or in addition to the first drive device.

- the pump drive is characterized in that the pump is mounted on an outstanding from the hollow shaft end of the inner shaft.
- the inner shaft is preferably made slightly longer than the hollow shaft, so that it protrudes with both ends of the hollow shaft.
- the pump is advantageous grown.
- the inner shaft is preferably rotatably connected to the planet carrier of the transmission.
- a further preferred embodiment of the pump drive is characterized in that a seal between a pump housing and the inner shaft is arranged in the axial direction between the pump and the hollow shaft.
- the Seal is arranged in the radial direction between the pump housing and the inner shaft and can be designed as a radial shaft seal.
- the hollow shaft is associated with a freewheel.
- the freewheel is preferably arranged between the housing of the second drive device and the hollow shaft and constitutes a backstop.
- the freewheel or the backstop makes it possible to drive the pump, if necessary, only with the first drive means and without the second drive means.
- Another preferred embodiment of the pump drive is characterized in that the freewheel is arranged on a gear end facing the hollow shaft. This arrangement has proved to be particularly advantageous in the context of the present invention.
- a further preferred embodiment of the pump drive is characterized in that the freewheel is arranged on a side facing away from the gear end of the hollow shaft.
- the freewheel can be arranged in the axial direction between the second drive device and the transmission.
- the freewheel still combined with a bearing for the hollow shaft.
- Figure 1 is a simplified illustration of a pump drive with a freewheel, which is arranged between a pump and a drive device and
- FIGS. 1 and 2 show a similar embodiment as in Figure 1, wherein the freewheel between the drive device and a transmission is arranged.
- a pump trigger 1; 51 shown simplified according to two embodiments.
- the pump drive 1; 51 comprises a first drive device 2 and a second drive device 3 for a pump 4.
- the pump 4 is designed, for example, as a vane pump and can be driven either only by the first drive device 2 or only by the second drive device 3.
- the pump 4 can also be driven simultaneously by both drive means 2 and 3.
- the pump 4 comprises a pump housing 5 which is mounted on a housing 8 which is fixedly arranged in the engine compartment and / or in a component of the drive train of a motor vehicle.
- the housing 8 belongs to the second drive device 3, which is designed as an electric motor 10.
- the electric motor 10 is associated with a hollow shaft 14 which can be rotated by the electric motor 10 in rotation.
- an inner shaft 15 is arranged, which protrudes with its two ends from the hollow shaft 14.
- a sealing device 16 preferably in the form of a radial shaft sealing ring, is arranged in the radial direction between the inner shaft 15 and the pump housing 5.
- the sealing device 16 is arranged in the axial direction in the pump housing 5 between the pump 4 and the housing 8 of the electric motor 10.
- the right in Figures 1 and 2 end of the inner shaft 15 is fixed to a planet carrier 18 of a transmission 20, which is designed as a planetary gear.
- planet gears 21 are rotatably mounted, which are in engagement with a sun gear 22 and a ring gear 24.
- the sun gear 22 is arranged centrally.
- the ring gear 24 is disposed radially outwardly coaxial with the sun gear 22.
- the planet gears 21 are arranged in the radial direction between the sun gear 22 and the ring gear 24.
- the ring gear 24 of the planetary gear 20 is provided with an internal toothing, in which engage the planetary gears 21 with corresponding external teeth.
- the ring gear 24 is provided with an external toothing, which is in engagement with an external toothing of a toothed wheel 25.

- the bearing of the hollow shaft 14 on the side facing the gear 20 is preferably in the region of the bearing shoulder 35. This bearing is not explicitly shown.
- the backstop for the hollow shaft 14 serves to drive the pump 4 if necessary without electric motor 10.
- In the other direction of rotation of the electric motor 10 may also serve in addition to the internal combustion engine 30 for an increase in the speed of the pump 4, if necessary.
- the transmission 20 remote from the end of the hollow shaft 14 at a bearing point 64 in the housing 8 of Electric motor 10 stored.

- a freewheel 60 is combined with the bearing 61 for the hollow shaft 14.
- the gear-side arrangement of the freewheel 60 shown in FIG. 2 provides the advantage that the freewheel 60 transmits a torque occurring in the reverse direction on the hollow shaft 14 directly to the housing 8 via the hollow shaft 14 over the shortest path from the sun gear 22.
- the portion of the hollow shaft 14 to the left of the freewheel 60, that is, on the side facing away from the gear 20 of the freewheel 60 is not acted upon by the high locking torque and can therefore be designed for the lower load only by the electric motor 10.
