Abstract
Description
Die Erfindung bezieht sich auf eine Antriebseinrichtung für ein Kraftfahrzeug mit einem Radantriebsstrang, einem Elektromotor mit einem Rotor und einer Koppelungseinrichtung zur Koppelung des Rotors mit jenem Radantriebsstrang in schaltbarer Weise.The invention relates to a drive device for a motor vehicle with a wheel drive train, an electric motor with a rotor and a coupling device for coupling the rotor with that wheel drive train in a switchable manner.
Aus
Bei Elektroantrieben von Kraftfahrzeugen, insbesondere bei Hybridantrieben besteht der Bedarf, den Elektroantrieb in bestimmten Betriebssituationen vom Antriebsstrang abzukoppeln. Beispielsweise können dann beim verbrennungsmotorischen Fahren Schleppverluste des elektrischen Antriebs vermieden werden.In electric drives of motor vehicles, especially in hybrid drives, there is a need to decouple the electric drive in certain operating situations from the drive train. For example, then drag losses of the electric drive can be avoided in internal combustion engine driving.
Zum An- und Abkoppeln des elektrischen Antriebs bei Hybridfahrzeugen sind mechanische Systeme bekannt, welche durch einen Aktuator (z.B. einen Hubmagneten, oder ein mechanisches Ausrücksystem wie bei Kupplungen) eine Koppelungseinrichtung, z.B. eine Reibkupplung, oder eine Klauenkupplung öffnen bzw. schließen. Weiterhin sind Lösungen bekannt, welche den elektromotorischen Antrieb durch einen Freilauf an den Antriebsstrang ankoppeln und bei Nicht-Betrieb abkoppeln.For coupling and decoupling the electric drive in hybrid vehicles, mechanical systems are known which use an actuator (e.g., a solenoid, or a mechanical release system such as clutches) to provide coupling means, e.g. a friction clutch, or a jaw clutch open or close. Furthermore, solutions are known which couple the electric motor drive by a freewheel to the drive train and decouple when not in operation.
Bei Systemen mit einem zusätzlichen Aktuator besteht der Nachteil in den zusätzlichen Kosten die der Aktuator verursacht. Bei Systemen mit Freilauf besteht der Nachteil durch die Funktionseinschränkung. So kann z.B. kann über einen Freilauf nicht rekuperiert werden.In systems with an additional actuator, the disadvantage is the additional cost that the actuator causes. In systems with freewheel the disadvantage is the function restriction. Thus, e.g. can not be recuperated via a freewheel.
Der Erfindung liegt die Aufgabe zugrunde, eine elektromotorische Antriebseinrichtung für ein Kraftfahrzeug zu schaffen, die sich durch einen robusten Aufbau und ein vorteilhaftes mechanisches Betriebsverhalten auszeichnet. The invention has for its object to provide an electric motor drive device for a motor vehicle, which is characterized by a robust design and advantageous mechanical performance.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Antriebseinrichtung für ein Kraftfahrzeug mit:
- – einem Radantriebsstrang,
- – einem Elektromotor mit einem Stator und einem gegenüber diesem um eine Motorachse drehbar gelagerten Rotor, und
- – einer Koppelungseinrichtung zur kinematischen Koppelung des Rotors mit dem Radantriebsstrang in schaltbarer Weise,
- – wobei die Koppelungseinrichtung ein einstellbar positionierbares Stellorgan umfasst, durch dessen Positionierung der Koppelungszustand der Koppelungseinrichtung festlegbar ist, und die Positionierung des Stellorgans durch axiale Verlagerung des Rotors erfolgt.
- A wheel drive train,
- - An electric motor with a stator and a rotatable relative to this about a motor shaft rotor, and
- A coupling device for kinematic coupling of the rotor to the wheel drive train in a switchable manner,
- - Wherein the coupling means comprises an adjustably positionable actuator, by the positioning of the coupling state of the coupling device can be fixed, and the positioning of the actuator takes place by axial displacement of the rotor.
Dadurch wird es auf vorteilhafte Weise möglich, über die am Rotor selbst angreifenden Kräfte die Koppelungseinrichtung zu betätigen und den Rotor selektiv an den Radantriebsstrang anzukoppeln, oder von diesem abzukoppeln. Die schaltbare Koppelungseinrichtung kann eine Trennkupplung sein, welche das angetriebene Rad vollständig vom jeweiligen Antriebsmotor trennt. This advantageously makes it possible to actuate the coupling device via the forces acting on the rotor itself and to couple the rotor selectively to the wheel drive train, or decouple it from this. The switchable coupling device may be a separating clutch, which completely separates the driven wheel from the respective drive motor.
Durch das erfindungsgemäße Lösungskonzept wird es möglich, auf einen zusätzlichen Aktuator zu verzichten und dennoch den vollen Funktionsumfang einer schaltbaren Koppelungseinrichtung zur Verfügung zu stellen. The solution according to the invention makes it possible to dispense with an additional actuator and nevertheless to provide the full range of functions of a switchable coupling device.
Die Erfindung schafft eine Möglichkeit durch welche sich bei elektrischen oder hybriden Antrieben die E-Maschine selbsttätig an den Antriebsstrang ankoppeln oder vom Antriebsstrang abkoppeln lässt. The invention provides a possibility by which the electric motor can be automatically coupled to the drive train or decoupled from the drive train in the case of electric or hybrid drives.
Gemäß einer besonders bevorzugten Ausführungsform der Erfindung ist der Motor derart gestaltet, dass dieser einen konischen Rotor sowie einen entsprechenden Stator mit konischer Bohrung umfasst. Ist dieser Motor stromlos, so drückt eine Feder den Rotor in eine Freilaufstellung. Wird der Motor bestromt wird der Rotor aufgrund seiner Geometrie vom elektrischen Feld in den Stator gezogen. Hierdurch wird die Koppelungseinrichtung in einen Koppelungszustand verbracht. According to a particularly preferred embodiment of the invention, the motor is designed such that it comprises a conical rotor and a corresponding conical bore stator. If this motor is de-energized, so a spring pushes the rotor in a freewheeling position. When the motor is energized, the rotor is pulled by the electric field into the stator due to its geometry. As a result, the coupling device is brought into a coupling state.
Der erfindungsgemäße Mechanismus wird zum Ankoppeln der E-Maschine genutzt. Dabei wird eine Kraft zum Schließen des Koppelelements durch den in den Stator gezogenen Rotor erzeugt. Der Rotor ist auf der Antriebswelle axial verschiebbar aber drehfest gelagert, so dass Drehmoment auf die Antriebswelle übertragen werden kann. Zum Öffnen der Koppelungseinrichtung befindet sich eine Feder auf der Antriebswelle. Diese drückt den Rotor aus dem Stator wenn dieser nicht bestromt ist. Die Koppelungseinrichtung wird somit geöffnet.The mechanism according to the invention is used for coupling the electric motor. In this case, a force for closing the coupling element is generated by the drawn into the stator rotor. The rotor is axially displaceable on the drive shaft but rotatably mounted so that torque can be transmitted to the drive shaft. To open the coupling device is a spring on the drive shaft. This pushes the rotor out of the stator when it is not energized. The coupling device is thus opened.
Idealerweise kann der Rotor bereits in Drehung versetzt werden bevor er vollständig in den Stator gezogen wird. Damit ist es möglich, die Antriebsdrehzahl an die Abtriebsdrehzahl anzugleichen bevor die Koppelungseinrichtung geschlossen wird. Die Stärke der Bestromung steht hierbei im Verhältnis zur Federkraft und muss immer zusätzlich aufgebracht werden. Ideally, the rotor may already be rotated before it is fully pulled into the stator. This makes it possible to match the drive speed to the output speed before the coupling device is closed. The strength of the current supply is in relation to the spring force and must always be additionally applied.
Die Koppelungseinrichtung kann so ausgebildet werden, dass diese eine kraft- und/oder formschlüssige Koppelung des Ein- und Ausgangs ermöglicht. Insbesondere kann die Koppelungseinrichtung mit einer Synchronisationseinrichtung versehen werden durch welche ähnlich wie bei Schaltgetrieben zunächst eine reibschlüssige Koppelung und dann eine formschlüssige Koppelung beispielsweise durch eine Klauenkupplung erfolgt. Falls der zur Drehung des Rotors benötigte Strom den Rotor teilweise oder vollständig in den Stator zieht, muss die dadurch entstehende Axialkraft zum Schließen des Koppelelements berücksichtigt werden.The coupling device can be designed so that this allows a positive and / or positive coupling of the input and output. In particular, the coupling device can be provided with a synchronization device by means of which, similar to manual transmissions, first a frictional coupling and then a positive coupling takes place, for example, by a dog clutch. If the current required for the rotation of the rotor pulls the rotor partially or completely into the stator, the resulting axial force must be considered for closing the coupling element.
Im Falle einer formschlüssig koppelnden Koppelungseinrichtung wird vorzugsweise zusätzlich eine Reibeinrichtung vorgesehen, welche, wie bei einer Getriebesynchronisierung den Formschluss verhindert solange An- und Abtriebsdrehzahl voneinander verschieden sind und gleichzeitig eine Kraft zum Schließen des Koppelelements anliegt. Der Motor muss zusätzlich zu dem Trägheitsmoment das entstehende Reibmoment aufbringen.In the case of a positively coupling coupling device, a friction device is preferably additionally provided, which, as in a transmission synchronization prevents the form-fitting as long as input and output speed are different from each other and at the same time bears a force to close the coupling element. In addition to the moment of inertia, the motor must apply the friction torque that is generated.
Das erfindungsgemäße Konzept kann so umgesetzt werden, dass dieses sowohl für Rechtsals auch Linkslauf geeignet ist. Die E-Maschine kann Drehmoment abgeben und aufnehmen (Rekuperieren). Durch das erfindungsgemäße Konzept ergibt sich ein Entfall eines zusätzlichen Aktuators bei vollem Funktionsumfang. Das Ankoppeln des Motors ist bei beliebiger Abtriebsdrehzahl (inkl. Stillstand) möglich. Die Erfindung stellt eine Möglichkeit dar, dass sich bei elektrischen oder hybriden Antrieben die E-Maschine selbsttätig an den Antriebsstrang ankoppelt oder vom Antriebsstrang abkoppelt. Durch die axiale Verschiebbarkeit des Rotors entsteht ein Freiheitsgrad der erfindungsgemäß zur Betätigung eines Koppelelements herangezogen wird.The inventive concept can be implemented so that this is suitable for both legal and anti-clockwise rotation. The electric motor can deliver and record torque (recuperation). The concept according to the invention results in the omission of an additional actuator with full functionality. The coupling of the motor is possible at any output speed (including standstill). The invention represents a possibility that couples in electric or hybrid drives, the electric motor automatically to the drive train or decoupled from the drive train. The axial displaceability of the rotor creates a degree of freedom which is used according to the invention for actuating a coupling element.
Der Radantriebsstrang kann so ausgebildet werden, dass dieser ein Achsgetriebe umfasst zur Aufteilung der Antriebsleistung auf eine linke und auf eine rechte Radantriebswelle. Alternativ hierzu kann der Radantriebsstrang auch so gestaltet werden, dass der Radantriebsstrang eine Einzelradantriebsmechanik bildet. The wheel drive train can be designed such that it comprises an axle drive for distributing the drive power to a left and to a right wheel drive shaft. Alternatively, the wheel drive train can also be designed so that the wheel drive train forms a Einzelradantriebsmechanik.
Bei beiden vorgenannten Varianten des Radantriebsstranges ist es möglich, wenigstens ein Zwischengetriebe vorzusehen, das kinematisch in einem Zwischenbereich zwischen dem Elektromotor und dem Achsgetriebe vorgesehen ist und eine „Übersetzung ins Langsame“, d.h. eine Drehmomentenerhöhung bewirkt. Dieses Zwischengetriebe kann dabei zwischen der Koppelungseinrichtung und dem Achsgetriebe oder auch zwischen dem Elektromotor und der Koppelungseinrichtung vorgesehen werden. Auch der Einsatz von zwei Zwischengetrieben an den vorgenannten Positionen ist möglich. Letztere Variante erweist sich besonders vorteilhaft, da dann die Koppelungseinrichtung in einem Systemabschnitt mit mittleren Drehmomenten und mittleren Drehzahlen sitzt und beim Öffnen der Koppelungseinrichtung der intern schnell drehende Getriebeteil abgekoppelt ist.In both of the aforementioned variants of the wheel drive train, it is possible to provide at least one intermediate gear which is kinematically provided in an intermediate region between the electric motor and the axle gear and a "translation to the slow", i. causes a torque increase. This intermediate gear can be provided between the coupling device and the axle drive or between the electric motor and the coupling device. The use of two intermediate gears to the above positions is possible. The latter variant proves to be particularly advantageous, since then the coupling device is seated in a system section with average torques and average speeds and disconnected when opening the coupling device of the internally rapidly rotating gear part.
Die Koppelungseinrichtung kann als formschlüssig koppelnde Kupplung, z.B. als ggf. vollsynchronisierte Klauenkupplung oder Schiebemuffenkupplung ausgeführt sein. Weiterhin kann die Koppelungseinrichtung auch als reibschlüssig koppelnde Kupplung ausgebildet sein.The coupling device can be used as a form-fitting coupling, e.g. be executed as possibly fully synchronized jaw clutch or sliding sleeve coupling. Furthermore, the coupling device can also be designed as a frictionally coupling coupling.
Die Antriebseinrichtung bildet gemäß einem besonderen Aspekt der vorliegenden Erfindung Bestandteil eines Hybridantriebssystems und umfasst auch eine Brennkraftmaschine, die unter Zwischenschaltung eines Getriebes selektiv an den Radantriebsstrang ankoppelbar ist.According to a particular aspect of the present invention, the drive device forms part of a hybrid drive system and also comprises an internal combustion engine which can be selectively coupled to the wheel drive train with the interposition of a transmission.
Erfindungsgemäß wird eine spezielle E-Maschine mit konisch ausgebildetem, axial verlagerbarem Rotor, der in einen Stator mit konischer Öffnung über die Kraftwirkung des magnetischen Feldes des Stators verlagerbar bzw. anordbar ist in einem Antriebstrang eines Fahrzeuges eingesetzt. Der E-Motor kann insbesondere in einem Hybridantriebstrang mit Verbrennungskraftmaschine (VKM), E-Maschine und Getriebe verwendet werden, wobei dieser E-Motor aufgrund der Verlagerbarkeit des konischen Rotors ohne einen separaten Aktor axial gegen eine Axialkraft in den Stator verlagerbar und damit in den Antriebstrang über ein Koppelelement (z.B. Synchronisierung) einkoppelbar ist. In der gekoppelten Stellung kann der Rotor gemäß einer besonders bevorzugten Ausführungsform der Erfindung verriegelt werden, so dass auch Rekuperieren möglich ist.According to the invention, a special electric machine with a conically designed, axially displaceable rotor which can be displaced or arranged in a stator with a conical opening via the force effect of the magnetic field of the stator is used in a drive train of a vehicle. The electric motor can be used in particular in a hybrid powertrain with internal combustion engine (VKM), e-machine and gear, said electric motor due to the displaceability of the conical rotor without a separate actuator axially against an axial force in the stator displaced and thus in the Drive train via a coupling element (eg synchronization) can be coupled. In the coupled position, the rotor can be locked according to a particularly preferred embodiment of the invention, so that recuperation is possible.
