Description

Die vorliegende Erfindung betrifft ein Fahrzeug mit Verbrennungs-Antriebsmaschine und Elektromotor, welche wahlweise, zum Antrieb des Fahrzeuges mit dessen Laufrädern kuppelbar sind. The present invention relates to a vehicle with an internal combustion engine and an electric motor, which can optionally be coupled to the wheels of the vehicle to drive it.

Während bei herkömmlichen Benzin- resp. Diesel-PKW's der spezifische Brennstoffverbrauch auf Landstrassen und Autobahnen recht gut ist, sind die Stadtverbräuche viel zu hoch. Dies ist besonders ärgerlich, weil, wegen der niedrigen Durchschnittsgeschwindigkeit in der Stadt, die effektiven Verluste durch Roll- und Luftreibung sehr klein sind. Der hohe spezifische Verbrauch ist bedingt durch lange Leerlaufphasen, den schlechten Wirkungsgrad des Verbrennungsmotors im Teillastbereich sowie die Anfahr- und Bremsverluste. While with conventional gasoline resp. Diesel cars the specific fuel consumption on country roads and highways is quite good, the city consumption is much too high. This is particularly annoying because, due to the low average speed in the city, the effective losses from rolling and air friction are very small. The high specific consumption is due to long idling phases, the poor efficiency of the internal combustion engine in the partial load range and the start-up and braking losses.

Es wurde daher von den Automobilclubs immer wieder daraufhingewiesen, dass durch Abschalten des Motors in Staus, vor Ampeln usw. Benzin gespart werden kann. Dies ist aber in der Praxis sehr unkomfortabel und wird darum kaum gemacht. Immer wenn sich die wartende Kolonne um einige Meter bewegt, muss der Motor von neuem gestartet werden. Für eine minimale erforderliche Leistung wird eine z.B. 50 KW starke Maschine gestartet, wobei der grösste Teil der benötigten Energie in Form von innerer Reibung, Kupplungswärme usw. verloren geht. The automobile clubs have therefore repeatedly pointed out that switching off the engine in traffic jams, in front of traffic lights etc. can save fuel. In practice, however, this is very uncomfortable and is therefore rarely done. Whenever the waiting column moves a few meters, the engine must be restarted. For a minimum required performance, e.g. 50 KW machine started, with most of the energy required being lost in the form of internal friction, clutch heat, etc.

Es ist ein Hybridantrieb für Fahrzeuge, insbesondere Kraftfahrzeuge, bestehend aus einem Verbrennungsmotor und einem Elektromotor, die miteinander kuppelbar sind, bekannt geworden, wobei mindestens ein Elektromotor mit seiner Welle unmittelbar oder über ein Getriebe an die Antriebselemente des Fahrzeuges, wie Räder, gekoppelt ist und der Verbrennungsmotor über eine auskuppelbare Kupplung mit der Welle des Elektromotors verbunden ist. Hierbei hat der verwendete Elektromotor nicht nur die Aufgabe, das Fahrzeug anzutreiben, sondern er kann auch, als Generator geschaltet, zur Aufladung der Batterien, d.h. zur Erzeugung der elektrischen Antriebsenergie, dienen. A hybrid drive for vehicles, in particular motor vehicles, consisting of an internal combustion engine and an electric motor, which can be coupled to one another, has become known, at least one electric motor being coupled with its shaft directly or via a transmission to the drive elements of the vehicle, such as wheels, and the internal combustion engine is connected to the shaft of the electric motor via a clutch that can be disengaged. Here, the electric motor used not only has the task of driving the vehicle, but it can also, when switched as a generator, charge the batteries, i.e. serve to generate the electrical drive energy.

Derartige Hybridantriebe bestehen im allgemeinen aus einem Verbrennungsmotor und einem Elektromotor, die abwechselnd, je nach der Antriebsart, mit der das Fahrzeug in Bewegung gesetzt werden soll, beispielsweise über eine Kupplung und gegebenenfalls über ein Getriebe mit den Antriebselementen, wie Rädern, verbunden werden. Such hybrid drives generally consist of an internal combustion engine and an electric motor which, depending on the type of drive with which the vehicle is to be set in motion, are alternately connected to the drive elements, such as wheels, for example via a clutch and, if appropriate, via a transmission.

Es ist ferner bekannt, die Achse von Verbrennungsmotoren mit einem Elektromotor mit Anlasser zu kuppeln, It is also known to couple the axis of internal combustion engines to an electric motor with a starter,

wobei dieser als Motor-Generator ausgeführte Elektromotor die Aufgabe hat, den Verbrennungsmotor anzulassen und im laufenden Zustand des Verbrennungsmotors als Generator die Batterie aufzuladen (DE-OS 25 01 386). this electric motor, designed as a motor-generator, has the task of starting the internal combustion engine and charging the battery as a generator when the internal combustion engine is running (DE-OS 25 01 386).

Das Problem, das Fahrzeug allein mit als Anlasser dimensioniertem Elektromotor bei abgeschaltetem Verbrennungsmotor zu bewegen, ist indessen neu und eine sinnreiche Ausführung, welche diesem Begehren aus dem Vorerwähnten Rechnung trägt, nicht bekannt geworden. The problem of moving the vehicle alone with the electric motor dimensioned as a starter when the internal combustion engine is switched off is new, however, and a sensible embodiment which takes this desire into account from the aforementioned is not known.

Die vorliegende Erfindung, welche dieses Problem löst, zeichnet sich dadurch aus, dass der Elektromotor ausschliesslich als Anlasser für den Verbrennungsmotor und als Stromerzeuger für das Laden einer Batterie ausgelegt ist, und dass Kupplungsmittel vorgesehen sind, um bei gelöster Antriebsverbindung zwischen den Laufrädern und Verbrennungs* Antriebsmaschine die Anlassvorrichtung mit den Laufrädern in Wirkverbindung zu bringen und das Fahrzeug zu bewegen. The present invention, which solves this problem, is characterized in that the electric motor is designed exclusively as a starter for the internal combustion engine and as a power generator for charging a battery, and in that coupling means are provided in order to, when the drive connection between the impellers and combustion * is released, Drive machine to bring the starter device into operative connection with the wheels and to move the vehicle.

Ein Ausführungsbeispiel der Erfindung wird anschliessend anhand einer schematischen Zeichnung erläutert, welche einen Längsschnitt durch eine Fahrzeugausrückkupplung zeigt, mit schematisch dargestelltem Anlasser und einem Teil eines Antriebs-Verbrennungsmotors. An exemplary embodiment of the invention is subsequently explained with reference to a schematic drawing, which shows a longitudinal section through a vehicle clutch, with a schematically illustrated starter and part of a drive internal combustion engine.

Eine Anlassvorrichtung 1 weist einen Anlasserelektromotor 3 auf, welcher normaler Bauart ist und batteriege-spiesen ist. Rein schematisch ist ebenfalls ein Teil einer Verbrennungs-Antriebsmaschine für das Fahrzeug dargestellt, deren Wellenende 2 mit einem Schwungrad 4 versehen ist. Diesem schliesst sich eine Kupplung 5 mit einer Kupplungsscheibe 6 an. Es handelt sich um eine im Automobilbau bestens bekannte, sog. ausrückbare Kupplung, deren Betätigung mittels eines nicht dargestellten Fusspedals erfolgt. Auf der Abtriebsseite der Kupplung 5 ist eine Getriebewelle 8 dargestellt, der normalerweise ein Schaltgetriebe (nicht dargestellt) nachgeschaltet ist. Die Getriebewelle 8, Trägerin der Kupplungsscheibe 6, ist über ein Wälzlager 9 im Antriebswellenende 2 gelagert. A starter device 1 has a starter electric motor 3, which is of normal construction and is battery-powered. Part of a combustion engine for the vehicle is also shown purely schematically, the shaft end 2 of which is provided with a flywheel 4. This is followed by a clutch 5 with a clutch disc 6. It is a so-called disengageable clutch that is best known in automotive engineering and is actuated by means of a foot pedal, not shown. On the output side of clutch 5, a transmission shaft 8 is shown, which is normally followed by a manual transmission (not shown). The gear shaft 8, carrier of the clutch disc 6, is mounted in the drive shaft end 2 via a roller bearing 9.

Der Anlassermotor 3 weist ein Zahnritzel 11 auf, welches durch ein entsprechendes Schaltorgan, normalerweise betätigt durch einen Zündschlüssel, in bekannter Weise mit einem Zahnkranz 12 in kämmende Verbindung gebracht werden kann. Normalerweise war der Zahnkranz 12 auf dem Schwungrad 4 angeordnet, derart, dass beim Anlassen und gelöster Verbindung zu den angetriebenen Rädern die Verbrennungs-Antriebsmaschine gestartet werden konnte. The starter motor 3 has a pinion 11, which can be brought into meshing connection with a ring gear 12 in a known manner by means of a corresponding switching element, normally actuated by an ignition key. Normally, the ring gear 12 was arranged on the flywheel 4 in such a way that the internal combustion engine could be started when starting and disconnected from the driven wheels.

Bei der vorliegenden Ausführung befindet sich dieser Zahnkranz 12 auf der Kupplungsscheibe 6, so, dass bei gelöster Kupplung 5 d.h. bei unterbrochener Verbindung zwischen Getriebewelle 8 und Antriebswellenende 2 das Ritzel 11 des Anlassermotors 3 mit dem Zahnkranz 12 in Eingriff gelangt. Gleichzeitig wird der Anlassermotor 3 erregt, so dass er über das Ritzel 11 und den Zahnkranz 12 die Kupplungsscheibe 6 und mithin die Getriebewelle 8 treibt. Wenn nun das anschliessende Getriebe beispielsweise in den ersten Gang geschaltet ist, so kann, durch Betätigung des Schaltorgans, das Fahrzeug bewegt werden, ohne dass die Verbren-nungs-Antriebsmaschine mitgedreht werden muss. In the present embodiment, this ring gear 12 is located on the clutch disc 6 so that when the clutch 5 is released, i. when the connection between the transmission shaft 8 and the drive shaft end 2 is interrupted, the pinion 11 of the starter motor 3 engages with the ring gear 12. At the same time, the starter motor 3 is excited so that it drives the clutch disc 6 and thus the transmission shaft 8 via the pinion 11 and the ring gear 12. If the subsequent transmission is now shifted into first gear, for example, the vehicle can be moved by actuating the switching element without the combustion engine having to be rotated as well.

Der in jedem PKW vorhandene Anlasser wird also dazu The starter that is present in every car will become one

verwendet, das Fahrzeug, ohne den Verbrennungsmotor mitzudrehen, direkt anzutreiben. Ein herkömmliches Fahrzeug erreicht so mühelos eine Geschwindigkeit von 10 km/h und überwindet Steigungen von ca. 2%. Selbst mit den serienmäs-sigen Batterien ist bei einer 50% Entladung ein elektrischer Betrieb von 15-30 min. problemlos. used to drive the vehicle directly without rotating the internal combustion engine. A conventional vehicle can easily reach a speed of 10 km / h and overcome gradients of approximately 2%. Even with the standard batteries, an electrical operation of 15-30 minutes is possible with a 50% discharge. no problem.

Daher wird es nun viel öfters sinnvoll, den Verbrennungsmotor abzustellen. Unnötiges Starten, nur um einige Meter aufzuschliessen, kann unterbleiben. Neben dem Treibstoffverbrauch werden auch Umwelt und Nerven geschont. Therefore, it is now much more sensible to switch off the internal combustion engine. Unnecessary starting, just to unlock a few meters, can be avoided. In addition to fuel consumption, the environment and nerves are also protected.

Der Zahnkranz auf dem Schwungrad wird ersetzt durch einen zusätzlich an der Kupplungsscheibe befestigten Zahnkranz, allenfalls aus Nylon. Um den Motor anzulassen, muss die Leerstufe eingelegt werden. Die Kupplung darf nicht betätigt werden. Um den Anlasser als Antrieb benützen zu können, wird der erste Gang eingelegt und die Kupplung niedergedrückt. Der Anlassermotor kann dann nicht nur mit dem Zündungsschlüssel, sondern auch mit einem zusätzlichen Schalter in griffgünstigerer Position betätigt werden. Während der elektrischen Fahrt kann durch Loslassen der Kupplung auf sehr elegante Art auch der Verbrennungsmotor gestartet werden, sofern wieder zügige Fahrt möglich ist. The ring gear on the flywheel is replaced by an additional ring gear attached to the clutch disc, possibly made of nylon. In order to start the engine, the empty position must be inserted. The clutch must not be operated. In order to be able to use the starter as a drive, first gear is engaged and the clutch is depressed. The starter motor can then be operated not only with the ignition key, but also with an additional switch in a more convenient position. During the electric journey, the internal combustion engine can also be started in a very elegant way by releasing the clutch, provided that rapid travel is possible again.

Die konstruktiven Änderungen sind also minimal. Sie können entweder direkt bei der Herstellung in die Serie ein-fliessen, oder nachträglich vorgenommen werden, sozusagen als Zubehör. The design changes are minimal. They can either flow directly into the series during manufacture, or be carried out subsequently, as an accessory, so to speak.

Diese Fahrart ist empfehlenswert für das This driving style is recommended for the

- Aufschliessen bei Kolonnen-Handorgelbewegungen, - unlocking during column hand organ movements,

- Wegrollen aus Gefahrenbereichen bei Pannen, - rolling away from danger areas in the event of breakdowns,

- Aufschliessen bei Verkehrslichtern - kurze Grünphasen, - unlocking by traffic lights - short green phases,

- Aufschliessen bei Tankstellen, Parkhäusern, usw., s - Wegrollen aus bewohnten Gebieten bei Nacht, - unlocking at petrol stations, parking garages, etc., s - rolling away from inhabited areas at night,

- Fahren in geschlossenen Räumen und - Driving in enclosed spaces and

- als Ersatz für kurze Abschleppfahrten sowie in - as a replacement for short towing trips and in

- Wohnstrassen. - residential streets.

io Trotzdem das beschriebene Ausführungsbeispiel wohl die natürlichste Art der praktischen Ausführung der Erfindung darstellt, ist es grundsätzlich möglich, den Anlasser, beispielsweise über ein entsprechendes Getriebe, direkt auf ein oder mehrere Antriebsräder wirken zu lassen, oder auf die i5 nicht angetriebenen Räder. Grundsätzlich ist es auch möglich, einen zweiten Anlasser vorzusehen, welcher nur die Funktion des Antriebes bei abgeschaltetem Hauptantriebsmotor haben könnte. Es ist ferner möglich, den Anlasser auf die Antriebswelle der Räder wirken zu lassen. Die einzige Bedingung, welche bei einem derartigen Fahrzeug zu beachten ist, ist die Möglichkeit, den Verbrennungs-Antriebsmotor von den durch einen Anlasser treibbaren Rädern zu trennen, was beispielsweise bei normalen Fahrzeugen durch Auskuppeln oder durch Einlegen des Leerlaufes im Getriebe erfolgt. In spite of the fact that the described embodiment represents the most natural way of practicing the invention, it is basically possible to let the starter act directly on one or more drive wheels, for example via a corresponding gear, or on the i5 non-driven wheels. In principle, it is also possible to provide a second starter, which could only have the function of the drive when the main drive motor is switched off. It is also possible to let the starter act on the drive shaft of the wheels. The only condition that must be observed in such a vehicle is the possibility of separating the combustion drive motor from the wheels drivable by a starter, which is done, for example, in normal vehicles by disengaging or by engaging the idle in the transmission.

Diese Hinweise und Überlegungen gelten sinngemäss sowohl für Fahrzeuge mit Schaltgetrieben als auch für solche mit automatischen, z.B. hydraulischen Getrieben, bzw. Fahrzeuge ohne spezielle Getriebe. These notes and considerations apply mutatis mutandis to vehicles with manual transmissions as well as those with automatic, e.g. hydraulic transmissions, or vehicles without special transmissions.
