Embodiment Construction

[0017] figure 1 An internal combustion engine 1 of a motor vehicle is shown schematically with a delivery device 2 for delivering oil from an oil sump 3 to a consumer 4 . The consumer 4 can be a lubricant circuit of the internal combustion engine 1 or a transmission (not shown) connected to the internal combustion engine 1 . The delivery device 2 has an oil pump 5 with a direct drive 6 realized by the internal combustion engine 1 and a switchable electric drive 7 . The motor 8 of the electric drive unit 7 that can be connected is connected to the electronic control unit 9, and the electronic control unit controls the electric drive unit 7 through the control line 10 according to the input signal, such as the motor speed, the required motor torque, the oil temperature and the set pressure. , and provide the electric drive 7 with the current of the motor vehicle electrical system 11 . In order to provide input signals, the control device 9 is connected to a signal line 12 .

Abstract

The invention relates to a delivery device (2) for a motor vehicle for delivering oil from an oil sump (3) to a lubricating oil circuit of an internal combustion engine (1), which delivery device hasas an oil pump (5) a double-stroke vane cell pump (28) having positive guidance of vanes (32). A direct drive (6) of the vane cell pump (28) via the internal combustion engine (1) is designed for a working point P2. An increased or reduced oil demand is compensated for by an electric drive (7) that can be connected. In this way, a compact and very small-dimensioned oil pump (5) can be employed.

Description

technical field [0001] The invention relates to a delivery device for a motor vehicle for delivering oil from an oil sump to a lubricating oil circuit of an internal combustion engine or to a transmission, which delivery device has a mechanical direct drive and can be switched on Oil pump driven by an electric drive connected to the / connection, wherein the oil pump with the rotor and the rotating part surrounding the rotor has two components movable relative to each other for conveying oil, the mechanical direct drive is opposite to the two A first of the mutually movable components is connected, and a switchable electric drive is connected to a second of the two mutually movable components. Background technique [0002] Such a delivery device is known, for example, from document DE 10 2011 084 542 A1. In such delivery devices, the oil pump can optionally be driven by a direct drive or a switchable electric drive. Parallel operation of two drives is also possible. The de...
