Definitions
- the present invention relates to an electric vehicle axial fluid pump which is designed as an internal rotor.
- the vehicular axial electric liquid electrolytic pump includes a pump housing that forms an axial inlet port and an axial outlet port for introducing and discharging the fluid, and an electric motor that drives an impeller.
- the object of the present invention is to provide an electric vehicle Axial- liquid pump, which is simpler in construction and therefore more economical to produce.
- the electric motor has a split tube disposed radially inside the at least one stator coil.
- the split tube separates a working space in which the liquid to be conveyed is located from an electronics compartment.
- the split tube can be part of a pump housing.
- a rotor body is rotatably arranged, which has at least one blade and which promotes the liquid from an inlet opening of the electric vehicle Axial-Flüssigkeltspumpe to an outlet.
- the rotor body is permanently magnetically formed.
- the rotor body is thus rotor and impeller in a single component.
- the rotor body is integrally formed.
- the motor stator which has the stator coils, at least partially embedded in a plastic spritzkör by which forms the can.
- the can is according to this embodiment formed radially inside the stator coils.
- a plain bearing in the context of the present invention, the arrangement of rotor body and can with a liquid-filled gap between the outer peripheral surface of the rotor body and the inner circumferential surface of the can is understood.
- the sliding bearing is cylindrical and stepped formed over the entire axial length of the rotor body.
- Such a plain bearing has the advantage that it is easy to produce. In addition, the installation of such a sliding bearing is simplified.
- the rotor body comprises plastic-bonded permanent magnet particles.
- These permanent magnet particles are particularly preferably neodymium particles and / or ferrite particles.
- Such rotor bodies can be produced particularly inexpensively, so that the cost-effectiveness of a corresponding electric vehicle axial-fluid pump can be increased.
- such a rotor body has a lower moment of inertia than a solid metal rotor, so that the efficiency of the electric vehicle axial fluid pump is improved.
- the rotor body is alternatively made of plastic, are embedded in the rotor laminations with permanent magnets. A rotor body produced in this way has the advantage that it is conventionally produced and is therefore inexpensive.
- the rotor is designed such that it has a plurality of blades and more preferably seven blades.
- the number of blades can thus be selected depending on the required hydraulic power of the pump.
- the figure shows: an electric vehicle axial-fluid pump in perspective longitudinal section according to the present invention.
- the figure shows an electric vehicle axial-fluid pump 10 according to the present invention, the drive motor is designed as an internal rotor.
- the electric vehicle axial-fluid pump 10 comprises a two-part pump housing 12, which has an axial inlet opening 14 for the admission of liquid into the electrical motor vehicle axial Liquid pump 10 forms. At an axially opposite to the inlet opening 14 longitudinal end of the pump housing 12, this forms an axial outlet opening 16 for discharging the liquid from the electric vehicle Axlal-Flüssiglgkeltspumpe 10.
- the electric vehicle axial-fluid pump 10 further comprises an electric motor 17 as a drive motor, which is provided in the pump housing 12.
- the electric motor 17 comprises a motor stator 18 which is located inside the pump housing 12 and radially outside.
- the motor stator 18 has a yoke body 19 and stator coils 20. The energization of the stator coils 20 is controlled by a provided on an outlet end and radially outer electronics unit 21st
- the return body 19 of the motor stator 18 is embedded in a plastic molded body, so that the plastic injection body forms a can 22.
- the split tube 22 is sealingly attached to the pump housing 12 by means of an inlet-side annular seal 24 and an outlet-side annular seal 26 and fluidly separates a working chamber 28, in which the liquid to be conveyed is located, from an electronics compartment 30.
- a rotor body 32 of the electric motor 17 designed as an axial impeller, which conveys the liquid along an axis of rotation 33 of the rotor body 32 from the inlet opening 14 to the outlet opening 16.
- the rotor body 32 is formed by a hollow cylinder 34 and seven provided within the hollow cylinder 34 and extending in the axial direction blades 36th LIST OF REFERENCE NUMBERS
