Problems solved by technology

A disadvantage here is, on the one hand, that the screw-on parts of the control disk and the ring lie radially outside the parts that are movable relative to each other, so that the rotor part has a large outer diameter
On the other hand, the pressure causes axial play to form in the rotor parts, which has a negative effect on the efficiency

Embodiment Construction

[0030] figure 1 A conveying device 1 is shown schematically with components of a hybrid drive 2 of a motor vehicle 12 shown schematically. The hybrid drive 2 has an internal combustion engine 3 , which drives the motor vehicle 12 via a transmission 4 , and an electric drive unit 5 for driving the motor vehicle 12 independently of the transmission. The clutch separates the internal combustion engine 3 from the transmission 4 . Delivery device 1 has an oil pump 7 for supplying oil to transmission 4 and a storage container 8 designed as an oil sump. The oil delivered by the oil pump 7 enters the transmission 4 and from there returns to the storage container 8 .

[0031] The transmission 4 has a direct drive 9 for driving an oil pump 7 . Furthermore, an electric drive 10 with an electric motor 11 is connected to the oil pump 7 . The oil pump 7 can thus be driven selectively via the electric drive 10 or via the direct drive 9 . Parallel operation of the direct drive 9 with the...

Abstract

The invention relates to a pumping device (1) for pumping oil from a reservoir (8) to a transmission (4) of a motor vehicle (12), comprising an oil pump (7), which can be driven either by a mechanical direct drive (9) or an electric drive (10) that can be activated. The oil pump (7) has two components (19, 19a) that can be moved in relation to each other for pumping the oil. The mechanical direct drive (9) is connected to one of the components (19, 19a) that can be moved in relation to each other, and the electric drive (10) that can be activated is connected to the other of the components (19, 19a) that can be moved in relation to each other. The components (19, 19a) that can be moved in relation to each other are arranged in a pump stage housing (20), which comprises two control disks (22, 23) and a ring (21) lying therebetween. The pump stage housing (20) is arranged in a pot-shaped component (40).

Description

technical field [0001] The invention relates to a delivery device for delivering oil from a storage container to a motor vehicle transmission, the delivery device having an oil pump that can be driven optionally by a mechanical direct drive or by a switchable electric drive, the oil pump With two parts movable relative to each other for oil delivery, the mechanical direct drive is connected to one of the parts movable relative to each other, while the switchable electric drive is connected to the The other ones of the parts are connected and the parts which are movable relative to each other are arranged in a pump stage housing which consists of two control discs with a ring in between. Background technique [0002] Such delivery devices are used in particular in motor vehicles with hybrid drives. In these hybrid drives, the oil pump for feeding the transmission is driven directly by the transmission. The function of the transmission and thus the oil pump should be kept ru...
