Description
Die Erfindung betrifft einen Hybridantrieb eines Kraftfahrzeugs und ein Verfahren zum Betrieb eines Kraftfahrzeugs mit einem Hybridantriebsstrang. Ferner betrifft die Erfindung ein Kraftfahrzeug mit einem erfindungsgemäßen Hybridantriebsstrang.The invention relates to a hybrid drive of a motor vehicle and a method for operating a motor vehicle with a hybrid drive train. Furthermore, the invention relates to a motor vehicle with a hybrid powertrain according to the invention.
Hybridantriebe für Kraftfahrzeuge sind bekannt und werden zunehmend eingesetzt, um die Leistungsfähigkeit der Kraftfahrzeuge sowie den Fahrkomfort und deren Effizienz, durch Reduzierung des Kraftstoffverbrauchs, zu erhöhen. Dabei werden bei einem Hybridantrieb ein Verbrennungsmotor und zumindest ein Elektromotor derart kombiniert, dass dadurch sowohl die Eigenschaften eines Verbrennungsmotors als auch eines Elektromotors für den Antrieb des Fahrzeugs ausgenutzt werden können. Dazu kann der Elektromotor auf verschiedene Weise in dem Kraftfahrzeug angeordnet werden, je nach Ausgestaltung des Hybridantriebsstrangs. Hybrid powertrains for motor vehicles are known and are increasingly used to increase the performance of motor vehicles and ride comfort and their efficiency, by reducing fuel consumption. In this case, in a hybrid drive, an internal combustion engine and at least one electric motor are combined in such a way that both the properties of an internal combustion engine and of an electric motor for driving the vehicle can be utilized. For this purpose, the electric motor can be arranged in various ways in the motor vehicle, depending on the design of the hybrid powertrain.
Die
Die Spannungsversorgung des Elektromotors beziehungsweise des Startergenerators wird typischerweise durch die Bordnetzspannung des Kraftfahrzeugs bereitgestellt. Dabei können Hybridfahrzeuge mit einer 12V Bordnetzspannung betrieben werden, wobei jedoch absehbar ist, dass das herkömmliche 12-Volt-Bordnetz zunehmend durch ein 48-Volt-Bordnetz ergänzt oder ersetzt wird, insbesondere auch im PKW Bereich. Dies hat den Vorteil, dass wesentlich höhere elektrische Leistungen durch das Bordnetz bereitgestellt werden können, ohne dazu einen maximalen Betriebsstrom über eine vorgeschriebene Schwelle ansteigen zu lassen. Gleichzeitig werden die Elektrik des Fahrzeugs und der Elektromotor noch im Niederspannungsbereich betrieben, wobei die Berührungsschutzgrenze von 60 Volt nicht erreicht wird.The power supply of the electric motor or the starter generator is typically provided by the vehicle electrical system voltage of the motor vehicle. This hybrid vehicles can be operated with a 12V board voltage, but it is foreseeable that the conventional 12-volt electrical system is increasingly supplemented or replaced by a 48-volt electrical system, especially in the car area. This has the advantage that much higher electrical power can be provided by the electrical system, without causing a maximum operating current to rise above a prescribed threshold. At the same time the electrical system of the vehicle and the electric motor are still operated in the low voltage range, the contact protection limit of 60 volts is not reached.
Aufgabe der vorliegenden Erfindung ist es, einen Hybridantrieb eines Kraftfahrzeugs bereitzustellen, durch den die Möglichkeiten eines Bordnetzes in einem Kraftfahrzeug, beispielsweise eines 48-V-Bordnetzes, im Vergleich zu herkömmlichen Hybridantrieben besser ausgenutzt werden können, wobei die Komplexität des Antriebs und die Kosten deutlich reduziert werden. The object of the present invention is to provide a hybrid drive of a motor vehicle, by which the possibilities of an electrical system in a motor vehicle, such as a 48-V electrical system, can be better utilized compared to conventional hybrid drives, the complexity of the drive and the cost significantly be reduced.

Gemäß einer Ausführungsform der Erfindung wird diese Aufgabe gelöst durch einen Hybridantrieb eines Kraftfahrzeugs, der einen Verbrennungsmotor und eine elektrischen Maschine aufweist, die in einem Antriebsstrang des Kraftfahrzeugs angeordnet sind. Der Antriebsstrang weist ferner ein Getriebe auf. Die elektrische Maschine ist in dem Antriebsstrang zwischen dem Verbrennungsmotor und dem Getriebe angeordnet. Dabei ist die elektrische Maschine mit dem Verbrennungsmotor mittels eines ersten formschlüssigen Kupplungselements koppelbar, und mit dem Getriebe mittels eines zweiten formschlüssigen Kupplungselements koppelbar. Als formschlüssiges Kupplungselement werden Kupplungen beschrieben, deren Verbindungszustand steuerbar ist und in denen Kupplungsteile formschlüssig und (steuerbar) lösbar ineinandergreifen. Als formschlüssiges Kupplungselement ist insbesondere eine formschlüssige Kupplung zu verstehen. According to one embodiment of the invention, this object is achieved by a hybrid drive of a motor vehicle having an internal combustion engine and an electric machine, which are arranged in a drive train of the motor vehicle. The drive train also has a transmission. The electric machine is arranged in the drive train between the internal combustion engine and the transmission. In this case, the electric machine with the internal combustion engine by means of a first positive coupling element can be coupled, and coupled to the transmission by means of a second positive coupling element. As a positive coupling element couplings are described, the connection state is controllable and in which coupling parts form-fit and (controllable) releasably intermesh. As a positive coupling element is to be understood in particular a positive coupling.

Es können Formschlusselemente direkt an einem Stirnende oder an beiden Stirnenden des Läufers vorgesehen sein, denen (vorzugsweise axial verschiebbare) Formschlusselemente gegenüber stehen. Gegenüberstehenden Formschlusselemente sind Teile einer der Kupplungselemente, wobei die Formschlusselemente einer Seite axial verschiebbar gelagert sind, wodurch der Kupplungszustand definiert werden kann. Insbesondere kann der Läufer einen Wicklungskopf aufweisen, von dem Formschlusselemente in axialer Richtung, von dem Läufer weg weisend, abstehen. Ferner kann auf einer Welle des Läufers ein Träger mit Formschlusselementen vorgesehen sein, die von dem Läufer weg ragen und die einen Teil eines Kupplungselements bilden. Zudem kann auf einer Welle des Läufers zu beiden Seiten des Läufers jeweils ein Träger mit Formschlusselementen vorgesehen sein, die von dem Läufer weg ragen. Jeder Träger, zusammen mit den davon weg ragenden Formschlusselementen, bildet einen Teil bzw. in funktioneller Sicht eine Hälfte eines Kupplungselements.

Opposing interlocking elements are parts of one of the coupling elements, wherein the interlocking elements of one side are mounted axially displaceable, whereby the coupling state can be defined. In particular, the rotor may have a winding head, from the positive-locking elements in the axial direction, facing away from the rotor, stand out. Further, on a shaft of the rotor, a carrier may be provided with positive locking elements which protrude away from the rotor and which form part of a coupling element. In addition, in each case a support with positive locking elements can be provided on a shaft of the rotor on both sides of the rotor, which protrude away from the rotor. Each carrier, together with the form-locking elements projecting therefrom, forms one part or, in functional view, one half of a coupling element. The interlocking elements are preferably formed integrally with the carriers, from which they protrude away.
