Description

Windstromgenerator fur Kraftfahrzeuge -Beschreibung-Wind power generator for motor vehicles -Description-

Die Erfindung betrifft einen Windstromgenerator für (elektrobetriebene) Kraftfahrzeuge. Es ist bekannt, daß (Antriebs)batterien (elektrobetriebener) Kraftfahrzeuge durch Solargeneratoren bei Lichteinwirkung aufgeladen werden können. Der Erfindung liegt daher die Aufgabe zugrunde, die Stromerzeugung für den Ladestrom dieser (Antriebs)batterien während des Fahrbetriebes bzw. im Stand, von Lichteinwirkung unabhängig, mit (Fahrt)windenergie zu realisieren. Gelöst wird diese Aufgabe durch die Merkmale im Anspruch 1. Vorteilhafte Ausgestaltungen der Erfindung sind in den Untenansprüchen gekennzeichnet. Bei dem erfindungsgemäßen Windstromgenerator für Kraftfahrzeuge wird die (Fahrt)windenergie durch ein auf der höchsten Fläche des Fahrzeugkarosserieaufbaus (z.B. auf dem Fahrzeugdach) oder auf der Fronthaube positioniertes Windschaufelrad gemäß einer vertikalen Achse in horizontal rotierende Drehbewegung ummoduliert. Diese Rotation des Windschaufelrades wird über einen wettergeschützten Keilriementrieb, welcher sich dabei entweder unterhalb der Fronthaube oder im Dachinnern befindet, dessen Keilriemen zudem durch eine federbelastete Spannrolle kontinuierlich-wartungsfrei nachgespannt wird, auf den Rotor eines (Drehstromgenerators übertragen. Das Übersetzungsverhältnis zwischen der treibenden und getriebenen, jeweils axial zugeordneten Riemenscheibe ist mit dem rechnerischen Einbezug der Parameter: (bremswirkende) elektromagnetische Erregerstrom-Feldstärke/strömungsgemäße Treibbarkeit des Windschaufehrades derart definiert, daß die Generator-Rotordrehzahl schon im niedrigen Fahrgeschwindigkeitsbereich (zwischen rel. 50 und 70 km/h) mit dem Fahrtwind allein bereits eine mittelmäßige Batterieladeleistung erzeugt, welche dadurch gleichfalls im Stand, bei einer dementsprechenden z.B. im Medium europäischer Herbst-/Seewindstärken gegeben ist, wodurch der nachgeschaltete Akkumulator als potentielle Energiequelle des davon antreibbaren Elektromobils praktisch über Nacht durch kinetische Windenergie, teilweise oder ganz (je nach Entladezustand), kapazitiv regeneriert werden kann. Die detaillierte Erläuterung über Aufbau und Funktion der dargestellten Erfindung erfolgt im Anschluß anhand der Zeichnungen.
Es zeigt Figur 1 Funktionsschema des (fahrt)windgemäßen (Drehstrom-) generatorantriebes; Positionierung des Windschaufelrades, des Generators und des Keilriemenantriebes, sowie den Schaltplan der Akkumulator-Aufladetechnik.The invention relates to a wind power generator for (electrically powered) motor vehicles. It is known that (drive) batteries of (electrically powered) motor vehicles can be charged by solar generators when exposed to light. The invention is therefore based on the object of generating electricity for the charging current of these (drive) batteries while driving or when stationary, independently of the effects of light, using (driving) wind energy. This object is achieved by the features in claim 1. Advantageous embodiments of the invention are characterized in the subclaims. In the wind power generator for motor vehicles according to the invention, the (driving) wind energy is modulated into horizontally rotating rotational movement according to a vertical axis by a wind vane wheel positioned on the highest surface of the vehicle body structure (e.g. on the vehicle roof) or on the front hood. This rotation of the wind vane wheel is transmitted to the rotor of a three-phase generator via a weatherproof V-belt drive, which is located either under the front hood or inside the roof, and whose V-belt is also continuously and maintenance-free re-tensioned by a spring-loaded tensioning roller. The transmission ratio between the driving and driven, axially assigned pulleys is defined by mathematically including the parameters: (braking) electromagnetic excitation current field strength/flow-related drivability of the wind vane wheel in such a way that the generator rotor speed already generates a moderate battery charging power with the airflow alone at low driving speeds (between rel. 50 and 70 km/h), which is also given when stationary, with a corresponding e.g. in the medium of European autumn/sea wind strengths, whereby the downstream accumulator as a potential energy source of the electric vehicle driven by it is charged practically overnight by kinetic wind energy, partially or completely (depending on the state of discharge). can be capacitively regenerated. The detailed explanation of the structure and function of the invention shown follows with the aid of the drawings.
Figure 1 shows the functional diagram of the wind-driven (three-phase) generator drive; positioning of the wind turbine wheel, the generator and the V-belt drive, as well as the circuit diagram of the battery charging technology.

-Figur 1--Figure 1-

In der Figur 1 ist das Funktionsschema des (fahrt)windgemäßen Drehstromgeneratorantriebes, die potentiellen Positionierungen des Windschaufelrades und des Keilriemenantriebes, sowie der Schaltplan der Akkumulator-Aufladetechnik, durch diesbezügliche Zeichnungen dargestellt.Figure 1 shows the functional diagram of the wind-driven three-phase generator drive, the potential positioning of the wind turbine wheel and the V-belt drive, as well as the circuit diagram of the battery charging technology, with relevant drawings.

Unten links ist die Positionierung des Windschaufelrades und des darunter angeordneten, gekapselten Keilriementriebes in den Varianten a) und b) dargestellt.The positioning of the wind turbine wheel and the encapsulated V-belt drive arranged underneath in variants a) and b) is shown at the bottom left.

Variante a): Hier ist das Windschaufelrad auf der höchsten Fläche des KFZ-Karosserieaufbaus, dem "DACH" positioniert (siehe auch die beiden biperspektiven KFZ-Darstellungen), womit dasselbe sowohl im Fahrbetrieb als auch im Stand den windproportional höchstmöglichen Drehmoment-Wirkungsgrad an den Drehstromgenerator weiterleiten kann.Variant a): Here the wind turbine is positioned on the highest surface of the vehicle body, the "ROOF" (see also the two bi-perspective vehicle images), which means that it can transmit the highest possible torque efficiency proportional to the wind to the three-phase generator both when driving and when stationary.

Die gekrümmte, schaufelförmige Struktur seiner Windschaufelradblätter gewährt, daß der (Fahrtwind, aus welcher potentiellen Richtung er auch kommen mag, diesen Rotationskörper immer in derselben Drehrichtung antreibt, was demzufolge nicht unbedingt einen Drehstromgenerator (bei welchem bekanntlich die Rotationsrichtung des Klauerpolläufers nicht von Bedeutung ist) als kinematisch nachgeschalteten Stromerzeuger erfordert. Die Wahl des Generatortyps (z.B. auch möglich Gleichstromgenerator etc.) ist demzufolge nicht auf einen derartigen beschränkt.The curved, blade-shaped structure of its wind turbine blades ensures that the wind, no matter from which potential direction it may come, always drives this rotating body in the same direction of rotation, which therefore does not necessarily require a three-phase generator (in which, as is well known, the direction of rotation of the yaw pole rotor is not important) as a kinematically connected power generator. The choice of generator type (e.g. also possible direct current generator etc.) is therefore not limited to one such type.

In welchem Maße dieses Schaufelrad, welches aus leichten Kunststoff- bzw. Kohlefasermaterialien gefertigt sein sollte, diese pneumatische Energie in rotatische umsetzen kann, hängt von der Anzahl und Formgebung seiner horizontal wirksamen Luftschaufelblätter - siehe obiges Windschaufelrad-Schrägbild - , seines Durchmessers, vor allem aber von seinem spezifisch vertikalen Abstand zur Dachoberfläche ab, da im Fahrbetrieb die aerodynamische Strömung von dem individuellen Schrägwinkel der Frontscheibe nach oben abgelenkt wird und somit nicht mit voller Intensität direkt auf der Dachoberfläche entlangströmt.The extent to which this impeller, which should be made of lightweight plastic or carbon fiber materials, can convert this pneumatic energy into rotary energy depends on the number and shape of its horizontally effective air impeller blades - see the above oblique image of the impeller -, its diameter, but above all on its specific vertical distance from the roof surface, since when driving the aerodynamic flow is deflected upwards by the individual oblique angle of the windscreen and thus does not flow directly along the roof surface with full intensity.

Der präzise Höhenabstand dieses Schaufelrades muß also durch pneumatische Farbströmungsversuche im Windkanal definiert werden (welche hier anhand der Pfeillinie bei der rechten KFZ-Darstellung simuliert wird), damit nicht nur die horizontale Fahrtwindebene, sondern auch die "volle" Frontscheiben-Aufwindenergie, welche dann zwischen den beiden hier ersichtlichen Querstrichebenen liegt, an diesem Windschaufelrad angreifen kann.The precise height of this impeller must therefore be defined by pneumatic color flow tests in the wind tunnel (which is simulated here using the arrow line in the right-hand vehicle illustration), so that not only the horizontal airflow plane, but also the "full" windscreen updraft energy, which then lies between the two cross-stroke planes visible here, can act on this wind impeller.

Das Gehäuse des darunter befindlichen Keilriementriebes, dessen Draufsicht oberhalb/zwischen den beiden KFZ-Darstellungen ersichtlich ist, befindet sich - wie hier dargestellt - im Dachinnern und könnte insbesondere bei PKW im Dachhimmel integriert werden, unter welchem dabei auch die beiden Generator-/Regler-Kabelzuführungen siehe Schaltplan rechts oben - verlegt werden sollten.The housing of the V-belt drive underneath, the top view of which can be seen above/between the two vehicle images, is located - as shown here - inside the roof and could be integrated into the roof lining, especially in cars, under which the two generator/regulator cable feeds should also be laid (see circuit diagram top right).

Variante b): Hier ist die Positionierung des Windschaufelrades auf der Front-/Motorhaube beispielhaft dargestellt.Variant b): Here the positioning of the wind vane wheel on the front/hood is shown as an example.

Da der Fahrtwind - gemäß der Aerodynamik - im Zenit dieser "HAUBE" wieder mit voller Intensität auf deren Oberfläche entlangströmt, kann dieses Schaufelrad dort knapp über dieselbe positioniert werden, was die Einschränkung des Fahrzeugfuhrer-Blickfeldes auf das potentielle Minimum beschränkt. Das Gehäuse des Keilriementriebes ist an der Innenseite dieser Fronthaube in geeigneter Weise arretiert (z.B. angeschraubt).Since the airflow - in accordance with aerodynamics - flows along the surface of this "HOOD" with full intensity at the zenith, this impeller can be positioned just above it, which limits the restriction of the driver's field of vision to the potential minimum. The housing of the V-belt drive is locked in place in a suitable manner on the inside of this front hood (e.g. screwed on).

Bei der DACH-Positionierungsvariante muß der (Drehstromgenerator derart flach ausgeführt sein, daß er im Riementrieb-Gehäuse mit integriert werden kann - siehe Gehäuse Draufsicht mit anstehender Bezeichnung: "G" -, dieser Fakt kann fronthaubenintern hingegen außer acht gelassen werden, und der Generator kann - dort positioniert - in beliebiger Baugröße/Formgebung - siehe hypothetische Strich/Strich-Umrißlinie - ausgeführt sein.In the case of the DACH positioning variant, the three-phase generator must be designed so flat that it can be integrated into the belt drive housing - see housing top view with the designation "G" -, however, this fact can be ignored inside the front hood and the generator - positioned there - can be designed in any size/shape - see hypothetical line/line outline.

Da sich bei elektrobetriebenen Mobilen dessen elektromotorisches Antriebsaggregat ebenfalls unter dieser Fronthaube befindet, ist dies hier anbei der dem Generator-Riementrieb nachgeschalteten Antriebsbatterie durch das bezügliche Schaltzeichen dargestellt. Oben links ist die rotatische Lagerung des Windschaufelrades mittels KegelroUen-/Axial-Rillenkugellager auf einer spezifischen, koaxialen Antriebswelle dargestellt, welche entweder durch die Fahrzeugdach- oder Fronthaubenwandung (entsprechend abgedichtet) geführt, drehfest mit der jeweils internen Riemenscheibe verbunden (verschraubt) ist. Die Lagerung der Generator-Riemenscheibe hingegen ist nicht separat, da hierfür gleichfalls die koaxiale Lagerung der Rotorwelle dient. Rechts daneben ist das Windschaufelrad und die darunter drehfest mittels dieser Antriebswelle verbundene Riemenscheibe im vertikalen Schrägbild dargestellt. Die koaxiale Antriebswelle bleibt hierbei durch das Schaufelrad verdeckt.Since the electric motor drive unit of electrically powered vehicles is also located under the front hood, this is shown here with the drive battery connected downstream of the generator belt drive using the relevant circuit symbol. At the top left, the rotary bearing of the wind vane wheel is shown using tapered roller/axial deep groove ball bearings on a specific, coaxial drive shaft, which is guided either through the vehicle roof or front hood wall (sealed accordingly) and is connected (screwed) to the respective internal pulley in a rotationally fixed manner. The bearing of the generator pulley, however, is not separate, since the coaxial bearing of the rotor shaft also serves this purpose. To the right, the wind vane wheel and the pulley connected below it in a rotationally fixed manner using this drive shaft are shown in a vertical oblique view. The coaxial drive shaft remains hidden by the vane wheel.

Die größere radikale Erstreckung der Riemenscheibe begründet sich mit dem Übersetzungsverhältnis zur diesbezüglich spezifisch kleineren Generator-Rotorriemenscheibe, welche bereits in der Beschreibung erläutert wurde. Rechts daneben ist der rotatische (Drehstrom)generatorantrieb mit der permanent-agierenden, federbelasteten Spannrolle (hier als kleinstes Drehelement ersichtlich) schematisch dargestellt. Die kreisförmigen Strich/Strich-Linien markieren dabei jeweils die interne Keilriemenlauffläche.The larger radical extension of the pulley is due to the gear ratio to the specifically smaller generator rotor pulley, which has already been explained in the description. To the right of this, the rotary (three-phase) generator drive with the permanently acting, spring-loaded tension pulley (visible here as the smallest rotating element) is shown schematically. The circular dash/dash lines mark the internal V-belt running surface.

Hieraus geht noch einmal die radiale Anordnung und etwaige Formgebung der Luftschaufelblätter hervor. Die radialen Pfeillinien weisen dabei auf den Drehrichtungsgleichsinn, die vertikale Pfeilmarkierung hingegen auf die Spannrollen-Wirkungsrichtung hin. Das vorherrschende Übersetzungsverhältnis könnte dabei in etwa zwischen 1:5 und 1:10 definiert sein. Schließlich ist rechts außen die Akkumulator-Aufladetechnik schaltplangemäß dargestellt. Sobald nun der Rotor (Klauenpolläufer) durch das Windschaufelrad per Windkraft auf die notwendige Drehzahl (1000/min) gebracht wird, zieht der (Zweikontakt)regler den Regleranker an und öfinet somit das Kontaktpaar. Damit ist der Reglerwiderstand vor die Erregerwicklung geschaltet (Reihenschaltung), d.h. die Erregerwicklung ist über den Reglerwiderstand mit der Fahrzeugmasse verbunden. Wegen des diesbezüglich verringerten Widerstandes fließt ein niedriger Erregerstrom - die Generatorladeleistung ist daher gering. Steigt die Rotordrehzahl infolge einer zu hohen (Fahrt)windstärke proportional zu hoch an, so wird das Magnetfeld der Spannungsspule weiter verstärkt. Der Regleranker wird noch weiter angezogen, bis das gegenüberstehende (hier rechtseitige) Kontaktpaar geschlossen ist. Beide Enden der Erregerwicklung sind mit Minus (D-) verbunden, d.h. die Erregerwicklung ist in sich selbst geschlossen, und es erfolgt eine vollständige Abregelung.This again shows the radial arrangement and possible shape of the air vane blades. The radial arrow lines indicate the same direction of rotation, while the vertical arrow markings indicate the direction of action of the tension pulleys. The predominant gear ratio could be defined as between 1:5 and 1:10. Finally, on the far right, the battery charging technology is shown according to the circuit diagram. As soon as the rotor (claw pole rotor) is brought to the required speed (1000 rpm) by the wind vane wheel using wind power, the (two-contact) regulator attracts the regulator armature and thus opens the contact pair. The regulator resistor is thus connected in front of the excitation winding (series connection), i.e. the excitation winding is connected to the vehicle ground via the regulator resistor. Due to the reduced resistance in this respect, a low excitation current flows - the generator charging power is therefore low. If the rotor speed increases proportionally too high due to excessive (travel) wind strength, the magnetic field of the voltage coil is further amplified. The regulator armature is further attracted until the opposite (here right-hand) contact pair is closed. Both ends of the excitation winding are connected to minus (D-), i.e. the excitation winding is closed in on itself and complete regulation takes place.

Bei wieder geringerer Rotordrehzahl/Generatorspannung wird der Strom in der Spannungsspule des Spannungsreglerelementes geringer; dadurch verringert sich ebenfalls die Anziehungskraft auf den federbelasteten Anker, der in die Mittellage bzw. Unterlage zurückfällt. Durch den jetzt wieder größer werdenden Erregerstrom steigt dieWhen the rotor speed/generator voltage decreases again, the current in the voltage coil of the voltage regulator element decreases; this also reduces the attractive force on the spring-loaded armature, which falls back into the middle position or base. Due to the excitation current now increasing again, the

Spannung im Generator, der Anker des Spannungsreglerelementes wird wieder angezogen. Die Schalthäufigkeit (Reglerfrequenz) der Reglerkontakte kann dabei zwischen 50 und 200 Schaltungen je Sekunde variieren.Voltage in the generator, the armature of the voltage regulator element is attracted again. The switching frequency (regulator frequency) of the regulator contacts can vary between 50 and 200 switching operations per second.

Sofern also der Erregerstrom durch die hier oben ersichtliche Schaltbrücke zugeschaltet wird, wird der (Fahrt)windenergie-Batterielademodus aktiviert und durch diese vorgenannte Reglertechnik optimal elektrotechnisch gesteuert. Da diese Schaltbrücke an die Klemme 30 (Dauerstrom) mit ihrem Stromzuflußkontakt angeschlossen ist, kann diese Aktivierung auch im Stand vom Fahrtschalter unabhängig erfolgen, womit bei entsprechend vorherrschender Windenergie - beispielsweise bei HerbsWSeewinden - die nachgeschaltete (Antriebs)batterie ebenfalls sozusagen über Nacht kapazitiv regeneriert werden kann.If the excitation current is switched on by the switching bridge shown above, the (driving) wind energy battery charging mode is activated and optimally controlled electrically by the aforementioned control technology. Since this switching bridge is connected to terminal 30 (continuous current) with its current supply contact, this activation can also take place independently of the driving switch when the vehicle is stationary, meaning that if the prevailing wind energy is sufficient - for example in the case of autumn/sea winds - the downstream (drive) battery can also be capacitively regenerated overnight.

Windstromgenerator für Kraftfahrzeuge nach Anspruch 1, dadurch gekennzeichnet,2. Wind power generator for motor vehicles according to claim 1, characterized in that daß der Antrieb des Drehstromgenerators über einen Keilriemen als Übertragungsmedium erfolgt, dessen spezifische Spannung permanent durch eine federbelastete Spannrolle realisiert wird und zudem wettergeschützt in einem spezifischen Gehäuse unterhalb der Motorhaube, bzw. fahrzeugdachintern integriert ist.that the three-phase generator is driven by a V-belt as a transmission medium, the specific tension of which is permanently realized by a spring-loaded tension pulley and is also weatherproofed in a specific housing underneath the bonnet or integrated into the vehicle roof. 3. Windstromgenerator für Kraftfahrzeuge nach Anspruch 1 und 2, dadurch gekennzeichnet,3. Wind power generator for motor vehicles according to claim 1 and 2, characterized in that daß die dem Übersetzungsverhältnis zwischen der Windschaufelrad- und Drehstromgenerator-Riemenscheibe zugrundeliegende Generator-Rotordrehzahl, sowie dessen (bremswirkende) elektromagnetische Erregerstrom-Feldstärke, und natürlich das Windschaufelrad selbst, derart ausgelegt ist, daß schon im niedrigen Fahrgeschwindigkeitsbereich (zwischen rel. 50 und 70 km/h) bereits eine mittelmäßige Batterieladeleistung erzeugt wird, welche dadurch gleichfalls im Stand, z.B. bei im Medium europäischer Herbst-/Seewindstärken gegeben ist, wodurch der nachgeschaltete Akkumulator als potentielle Energiequelle des davon antreibbaren Elektromobils praktisch über Nacht durch kinetische Windenergie, teilweise oder ganz (je nach Entladezustand), kapazitiv regeneriert werden kann.that the generator rotor speed underlying the gear ratio between the wind turbine and three-phase generator pulley, as well as its (braking) electromagnetic excitation current field strength, and of course the wind turbine itself, are designed in such a way that even at low driving speeds (between rel. 50 and 70 km/h) a moderate battery charging power is generated, which is also the case when stationary, e.g. in the medium of European autumn/sea wind strengths, whereby the downstream accumulator as a potential energy source of the electric vehicle driven by it can be capacitively regenerated practically overnight by kinetic wind energy, partially or completely (depending on the state of discharge).
