Description
Die Erfindung betrifft einen Hybridantriebsstrang für ein Kraftfahrzeug, wie einen Pkw, einen Lkw, einen Bus oder ein sonstiges Nutzfahrzeug, mit einem automatisierten Schaltgetriebe sowie einer elektrischen Maschine, wobei eine einen Rotor drehfest aufnehmende Antriebsachse der elektrischen Maschine rotatorisch / drehend mit einer Getriebewelle des Schaltgetriebes koppelbar ist.The invention relates to a hybrid powertrain for a motor vehicle, such as a car, a truck, a bus or other commercial vehicle, with an automated manual transmission and an electric machine, wherein a rotor rotatably receiving a rotor drive shaft of the electric machine rotatory / rotating with a transmission shaft of the gearbox can be coupled.
Gattungsgemäße Antriebsstränge sind aus dem Stand der Technik bereits in verschiedenen Ausführungen bekannt. Diesbezüglich offenbart die
Die bisher bekannten Hybridantriebsstränge haben jedoch häufig den Nachteil, dass sie aufgrund ihrer Ausbildung lediglich für höherklassige Fahrzeuge geeignet sind. Dies liegt einerseits an den relativ hohen Herstellungskosten dieser Antriebsstränge, andererseits an dem relativ hohen Gewicht. Diese bekannten Systeme sind daher häufig für leichtgewichtige Kleinfahrzeuge relativ ungeeignet.However, the previously known hybrid powertrains often have the disadvantage that they are only suitable for higher-class vehicles due to their training. This is due, on the one hand, to the relatively high production costs of these drive trains and, on the other hand, to the relatively high weight. These known systems are therefore often relatively unsuitable for lightweight small vehicles.
Es ist daher die Aufgabe der vorliegenden Erfindung, die aus dem Stand der Technik bekannten Nachteile zu beheben und insbesondere einen Hybridantriebsstrang zur Verfügung zu stellen, dessen Herstellaufwand weiter reduziert werden soll sowie ein möglichst geringes Gewicht aufweisen soll.It is therefore an object of the present invention to overcome the known from the prior art disadvantages and in particular to provide a hybrid powertrain available, the manufacturing cost is to be further reduced and should have the lowest possible weight.
Dies wird erfindungsgemäß dadurch gelöst, dass die elektrische Maschine als eine Asynchronmaschine ausgebildet ist.This is inventively achieved in that the electrical machine is designed as an asynchronous machine.
Im Vergleich zu den bisher häufig verwendeten permanent erregten Synchronmaschinen können durch die erfindungsgemäß eingesetzte Asynchronmaschine im Wesentlichen folgende zwei Probleme behoben werden. Da die elektrische Maschine „direkt“ (über die Getriebewelle) mit den Rädern verbunden ist, hat sie die Funktion im gesamten Drehzahlbereich zu arbeiten. Eine Drehzahlanpassung durch den Gangwechsel ist bisher in Abhängigkeit der Ausbildung des Schaltgetriebes sowie der Anbindung der elektrischen Maschine an die Getriebewelle unter Umständen nicht möglich. Aufgrund der Gegeninduktion reduziert sich dann die maximale Leistung der bisherigen Synchronmaschine beim Feldschwächebetrieb mit steigender Drehzahl. Zudem führt der Ummagnetisierungs- und Wirbelstromverlust bisher dazu, dass der Wirkungsgrad im hohen Drehzahlbereich deutlich schlechter wird. Diese beiden Nachteile können durch die Asynchronmaschine vermieden werden. Des Weiteren ist die Asynchronmaschine deutlich kostengünstiger als permanent erregte Synchronmaschinen, was insbesondere für Kleinfahrzeug attraktiv ist.In comparison to the previously frequently used synchronously excited synchronous machines, the following two problems can be remedied by the asynchronous machine used according to the invention. Since the electric machine is "directly" (via the gear shaft) connected to the wheels, it has the function to work in the entire speed range. A speed adjustment by the gear change is previously not possible depending on the design of the gearbox and the connection of the electric machine to the gear shaft. Due to the mutual induction then reduces the maximum power of the previous synchronous machine in field weakening operation with increasing speed. In addition, the Ummagnetisierungs- and eddy current loss so far causes the efficiency in the high speed range is significantly worse. These two disadvantages can be avoided by the asynchronous machine. Furthermore, the asynchronous machine is significantly less expensive than permanently excited synchronous machines, which is particularly attractive for small vehicles.
Weitere vorteilhafte Ausführungsformen sind in den Unteransprüchen beansprucht und nachfolgend näher erläutert.Further advantageous embodiments are claimed in the subclaims and explained in more detail below.
Ist die elektrische Maschine (mit der Antriebsachse) parallel zu der Getriebewelle, vorzugsweise einer Getriebeausgangswelle, des Schaltgetriebes angeordnet und über eine Koppeleinrichtung mit dieser verbindbar, kann der Hybridantriebsstrang mit einer so genannten P3-Hybridstruktur effektiv ausgebildet werden. Dadurch kann die elektrische Maschine individuell an die Getriebewelle angekoppelt oder von dieser entkoppelt werden. Durch diese achsparallele Anordnung der Asynchronmaschine über eine Übersetzung wird insbesondere bei der bevorzugten Ausbildung eines Front-Quer-Antriebes kein zusätzlicher Axialbauraum beansprucht.If the electric machine (with the drive axle) is arranged parallel to the transmission shaft, preferably a transmission output shaft, of the gearbox and can be connected to it via a coupling device, the hybrid powertrain can be effectively formed with a so-called P3 hybrid structure. This allows the electric machine to be individually coupled to the transmission shaft or decoupled from this. By this axially parallel arrangement of the asynchronous machine via a translation no additional axial space is claimed, in particular in the preferred embodiment of a front-transverse drive.
Alternativ hierzu ist es jedoch auch möglich, eine P4-Hybridstruktur zu verwenden, d.h. die elektrische Maschine bspw. in Form eines Radnabenmotors, an einem Rad des Kraftfahrzeuges anzuordnen, oder in Form einer elektrischen Achse / E-Achse im Kraftfahrzeug, im Anschluss an das Schaltgetriebe im Antriebsstrang, anzuordnen.Alternatively, however, it is also possible to use a P4 hybrid structure, i. the electric machine, for example, in the form of a wheel hub motor, to be arranged on a wheel of the motor vehicle, or in the form of an electrical axis / E-axis in the motor vehicle, following the manual transmission in the drive train to arrange.
Weiter von Vorteil ist es, wenn die elektrische Maschine an ein 48V-Bordnetz angeschlossen ist, bzw. in dieses 48V-Bordnetz integriert ist. Das 48V-Bordnetz hat insbesondere den Vorteil, dass es für die Leistungsklasse der elektrischen Maschine vollkommen ausreicht. Die Bordnetzspannung ist auf 48V beschränkt, wodurch insbesondere Hochvoltschutzmaßnahmen eingespart werden können. Um die elektrischen Verluste nicht zu groß werden zu lassen, arbeiten die elektrischen Hilfsaggregate ebenfalls mit 48V.Another advantage is when the electrical machine is connected to a 48V electrical system, or is integrated in this 48V electrical system. The 48V vehicle electrical system has the particular advantage that it is completely sufficient for the power class of the electric machine. The vehicle electrical system voltage is limited to 48V, which in particular high-voltage protection measures can be saved. In order not to let the electrical losses become too large, the electrical auxiliary units also work with 48V.
In diesem Zusammenhang ist es deshalb auch besonders vorteilhaft, wenn ein Starter des Verbrennungsmotors in diesem 48V-Bordnetz integriert / an diesem 48V-Bordnetz angeschlossen ist. Dieser weist dann nämlich ein besseres Start-Stopp- und Motorwiederstart-Verhalten auf.In this context, it is therefore particularly advantageous if a starter of the internal combustion engine is integrated in this 48V vehicle electrical system / connected to this 48V electrical system. This then has namely a better start-stop and engine restart behavior.
Zweckmäßig ist es auch, wenn an dem 48V-Bordnetz eine erste Batterie / 48V-Batterie angeschlossen ist / eine erste Batterie in dieses 48V-Bordnetz integriert ist, wobei diese erste Batterie wiederum vorzugsweise als Lithium-Ionen-Batterie ausgebildet ist. Dadurch wird ein elektrisches Fahren des Kraftfahrzeuges über eine bestimmte Reichweite effektiv erzielt. Besonders bevorzugt ist die erste Batterie dann so ausgeführt, etwa mit einer elektrischen Energie von 1 kWh, um mindestens eine Reichweite von 5 km durch ein reines elektrisches Fahren, d.h. bei ausgeschaltetem Verbrennungsmotor, zurückzulegen.It is also expedient if a first battery / 48V battery is connected to the 48V electrical system / a first battery is integrated in this 48V electrical system, this first battery is again preferably designed as a lithium-ion battery. Thereby, an electric driving of the motor vehicle over a certain range is effectively achieved. Particularly preferably, the first battery is then designed, for example with an electrical energy of 1 kWh, by at least one
Zudem ist es von Vorteil, wenn die erste Batterie eine elektrische Energie zwischen 0,5 kWh und 2,5 kWh, besonders bevorzugt von ca. 1 kWh, aufweist. Dadurch ist ein besonders geeigneter Kompromiss zwischen Gewicht und Reichweite des rein elektrischen Fahrens getroffen.In addition, it is advantageous if the first battery has an electrical energy between 0.5 kWh and 2.5 kWh, particularly preferably about 1 kWh. As a result, a particularly suitable compromise between weight and range of purely electric driving is made.
Des Weiteren ist es vorteilhaft, wenn das 48V-Bordnetz über einen Wandler (bevorzugt einen DC/DC-Wandler) mit einem 12V-Bordnetz verbunden ist / an dieses 12V-Bordnetz angeschlossen ist. Somit kann das konventionelle 12V-Bordnetz ebenfalls beibehalten werden.Furthermore, it is advantageous if the 48V vehicle electrical system is connected via a converter (preferably a DC / DC converter) to a 12V vehicle electrical system / is connected to this 12V vehicle electrical system. Thus, the conventional 12V electrical system can also be maintained.
An dem 12V-Bordnetz ist wiederum bevorzugt eine zweite Batterie / eine 12V-Batterie angeschlossen. Diese zweite Batterie dient als zusätzlicher Energiespeicher und ist weiter bevorzugt besonders kostengünstig als Bleibatterie ausgeführt. Über diese konventionelle zweite Batterie werden dann bevorzugt die üblichen Verbraucher betrieben, wie etwa eine Beleuchtung, ein Radio und ein Display, eine Sitz- und/oder Scheibenheizung, ein Hydraulikmodul für z.B. das ABS oder die Servo-Lenkung, Steuergeräte und/oder Aktoren insbesondere für Kupplung, Gänge, Scheibenwischer, Fenster, Schiebedach, Außenspiegel und/oder Sitzverstellung, und ähnliches.In turn, a second battery / a 12V battery is preferably connected to the 12V vehicle electrical system. This second battery serves as an additional energy store and is more preferably designed as a low-cost lead-acid battery. The conventional consumers are then preferably operated via this conventional second battery, such as lighting, a radio and a display, seat and / or window heating, a hydraulic module for e.g. the ABS or the servo-steering, control devices and / or actuators in particular for clutch, gears, windscreen wipers, windows, sunroof, exterior mirrors and / or seat adjustment, and the like.
Weiterhin ist es vorteilhaft, insbesondere bei der achsparallelen Bauweise des Hybridantriebsstranges, wenn die elektrische Maschine innerhalb eines Gehäuses des Schaltgetriebes angeordnet ist. Dadurch ist die elektrische Maschine relativ bauraumneutral integriert.Furthermore, it is advantageous, in particular in the paraxial design of the hybrid drive train, when the electric machine is arranged within a housing of the gearbox. As a result, the electric machine is integrated relatively space-neutral.
Zweckmäßig ist es auch, wenn die elektrische Maschine eine Dauerleistung zwischen 2 kW und 5 kW, besonders bevorzugt zwischen 2 kW und 3 kW, weiter bevorzugt von ca. 2,5 kW und/oder eine maximale Leistung zwischen 12 kW und 18 kW, besonders bevorzugt zwischen 14 kW und 16 kW, weiter bevorzugt von ca. 15 kW aufweist. Die maximale Leistung ist bevorzugt bei einer Drehzahl bei ca. 4000 U/min umgesetzt. Dadurch ist die elektrische Maschine für Kleinfahrzeuge weiter optimiert.It is also expedient if the electric machine has a continuous power of between 2 kW and 5 kW, particularly preferably between 2 kW and 3 kW, more preferably of approximately 2.5 kW and / or a maximum power of between 12 kW and 18 kW preferably between 14 kW and 16 kW, more preferably of about 15 kW. The maximum power is preferably implemented at a speed of about 4000 rpm. As a result, the electric machine for small vehicles is further optimized.
Ist die elektrische Maschine zur Erzeugung eines Nennmomentes / Nenndrehmomentes zwischen 5 Nm und 13 Nm, bevorzugt zwischen 4 Nm und 8 Nm, weiter bevorzugt von ca. 6 Nm und/oder eines maximalen Momentes / Drehmomentes zwischen 25 Nm und 50 Nm, besonders bevorzugt zwischen 30 Nm und 40 Nm, weiter bevorzugt von ca. 36 Nm, ausgebildet, wird ein ausreichendes Moment während des Betriebes des Kraftfahrzeuges durch die elektrische Maschine bereitgestellt.Is the electric machine for generating a rated torque / nominal torque between 5 Nm and 13 Nm, preferably between 4 Nm and 8 Nm, more preferably about 6 Nm and / or a maximum torque / torque between 25 Nm and 50 Nm, more preferably between 30 Nm and 40 Nm, more preferably formed of about 36 Nm, a sufficient moment during operation of the motor vehicle is provided by the electric machine.
In diesem Zusammenhang ist es zudem zweckmäßig, wenn die elektrische Maschine eine maximale Drehzahl zwischen 10000 U/min und 22000 U/min, besonders bevorzugt zwischen 18000 U/min und 22000 U/min, weiter bevorzugt von ca. 20000 U/min aufweist.In this context, it is also expedient for the electric machine to have a maximum speed of between 10,000 rpm and 22,000 rpm, more preferably between 18,000 rpm and 22,000 rpm, more preferably approximately 20000 rpm.
In anderen Worten ausgedrückt, ist somit ein besonders kostengünstiges Hybridisierungs- und Automatisierungskonzept, insbesondere für ein A-Segment, d.h. für Kleinfahrzeuge, umgesetzt. Erfindungsgemäß ist eine Kombination aus einem automatisierten Schaltgetriebe sowie einer Asynchronmaschine zur Verfügung gestellt. Die Asynchronmaschine ist bevorzugt achsparallel zu einer Ausgangswelle des Getriebes, insbesondere an einer Ausgangsseite, angeordnet.
