Abstract
Description
Die vorliegende Erfindung betrifft einen Kraftfahrzeugantrieb mit einer Brennkraftmaschine umfassend eine als Abtriebswelle dienende Kurbelwelle, sowie mit einem Elektromotor zum Starten der Brennkraftmaschine, der mit Hilfe einer Momentenübertragungsanordnung mit der Kurbelwelle koppelbar ist.The The present invention relates to a motor vehicle drive with a Internal combustion engine comprising a crankshaft serving as an output shaft, and with an electric motor for starting the internal combustion engine, with Help of a torque transfer arrangement can be coupled with the crankshaft.

Aufgabe der Erfindung ist es demgegenüber, einen Kraftfahrzeugantrieb bereit zu stellen, bei dem die Lebensdauer eines für Start-Stopp-Anwendungen vorgesehenen Elektromotors und seiner Kraftübertragungseinrichtung mit besonders einfachen Mitteln verlängert und der Kraftstoffverbrauch der Brennkraftmaschine reduziert werden kann.task the invention it is in contrast, a Motor vehicle drive to provide, in which the life one for Start-stop applications provided electric motor and its power transmission device extended with particularly simple means and the fuel consumption the internal combustion engine can be reduced.
Diese Aufgabe wird durch einen Kraftfahrzeugantrieb nach Anspruch 1 gelöst, bei dem die Momentenübertragungsanordnung ein auf der Kurbelwelle gelagertes Schwungrad, einen am Kurbelgehäuse und/oder am Motorblock gelagerten Anlasserkranz sowie einen Freilauf zur drehzahlabhängigen Kopplung und Entkopplung von Schwungrad und Anlasserkranz aufweist. Auf diese Weise lässt sich der größte Teil der Momentenübertragungsanordnung, insbesondere ein vorzusehendes Stirnradgetriebe (bzw. ein Riementrieb) sowie ein nachgeschaltetes Planetengetriebe sowie der Elektromotor, nach einem Startvorgang der Brennkraftmaschine bei einer bestimmten Grenzdrehzahl von der Kurbelwelle der Brennkraftmaschine trennen und stillsetzen. Damit können die Drehzahlen auf Seiten der Momentenübertragungsanordnung und des Elektromotors verschleißgünstig niedrig gehalten werden, und es wird ein Mitschleppen des Elektromotors und seiner Getriebe verbrauchsgünstig vermieden.These The object is achieved by a motor vehicle drive according to claim 1, at the torque transfer arrangement a flywheel mounted on the crankshaft, one on the crankcase and / or mounted on the engine block starter ring and a freewheel for speed-dependent coupling and decoupling of flywheel and starter ring has. To this Way lets the biggest part the torque transmission arrangement, in particular a spur gear (or a belt drive) to be provided as well as a downstream planetary gear and the electric motor, after a starting process of the internal combustion engine at a certain limit speed disconnect from the crankshaft of the engine and stop. With that you can the speeds on the part of the torque transmission arrangement and the Electric motor wear low be held, and there will be a dragging the electric motor and its transmission consumption avoided.
In Ausgestaltung der Erfindung weist der Freilauf von einem Federelement gehaltene, fliehkraft-betätigte Mitnehmerkörper auf. Damit ist eine einfache, wartungsfreie, automatisch arbeitende Anordnung vorgeschlagen. Die Mitnehmerkörper lösen sich drehmomentfrei vorzugsweise bereits unterhalb einer Leerlaufdrehzahl von ihrer Kontakfläche ab, so dass der Freilauf nach dem Motorstart keinem Verschleiß unterliegt.In Embodiment of the invention, the freewheel of a spring element held, centrifugal-operated driving element on. This is a simple, maintenance-free, automatic working Arrangement proposed. The driver body solve torque-free preferably already below an idling speed from its contact surface, so that the freewheel is not subject to wear after engine start.
In weiterer Ausgestaltung der Erfindung ist der Freilauf derart gestaltet, dass er in einem Betriebszustand der Brennkraft maschine, in dem die Kurbelwelle bei einer Grenzdrehzahl unterhalb einer Leerlaufdrehzahl rotiert, selbsttätig oder fremdgesteuert öffnet bzw. schließt. Derartige Anordnungen gestatten häufige Start-Stopp-Vorgänge der Brennkraftmaschine mit einem automatischen Stillsetzen des Elektromotors einschließlich der zugehörigen Getriebe.In Another embodiment of the invention, the freewheel is designed such that in an operating state of the internal combustion engine, in which the crankshaft at a limit speed below an idle speed rotated, automatically or opens externally or closes. Such arrangements allow frequent start-stop operations of Internal combustion engine with an automatic shutdown of the electric motor including the associated gearbox.
In weiterer Ausgestaltung der Erfindung gestattet die Freilaufkonstruktion, dass der Anlasserkranz über ein korrespondierendes Ritzel drehmomentfest mit dem Elektromotor gekoppelt ist. Damit ergibt sich eine zuverlässige Momentenübertragung, wobei Anlasserkranz und Ritzel ein fest eingespurtes Vorgetriebe derart bilden, dass ein nachgeschaltetes, dem Elektromotor zugeordnetes Planetengetriebe entsprechend dimensioniert sein kann. Eine Einspurvorrichtung wie bei einem herkömmlichen Starter entfällt hier. Die Anordnung dient erfindungsgemäß dazu, dass ein zeitaufwändiger Einspurvorgang des Anlasserritzels entfällt und der Kfz-Motor spontan gestartet werden kann.In further embodiment of the invention allows the freewheel design, that the starter wreath over a corresponding pinion torque-resistant with the electric motor is coupled. This results in a reliable torque transmission, wherein Starter ring and pinion a firmly meshed Vorgetriebe such form, that a downstream, the electric motor associated Planetary gear can be dimensioned accordingly. A Einspurvorrichtung like a conventional one Starter is eliminated here. The arrangement is used according to the invention that a time-consuming Einspurvorgang of the starter pinion deleted and the motor vehicle can be started spontaneously.
In weiterer Ausgestaltung der Erfindung sind Anlasserkranz und Ritzel als schrägverzahntes, vorzugsweise selbstschmierendes Zahnradpaar ausgeführt. Damit können eine besonders lange wartungsfreie Lebensdauer des Zahnradpaares sowie ein niedriges Laufgeräusch erreicht werden.In Another embodiment of the invention are starter ring and pinion as helical, preferably self-lubricating gear pair executed. In order to can a particularly long maintenance-free life of the gear pair as well as a low running noise be achieved.
In weiterer Ausgestaltung der Erfindung weist der Anlasserkranz einen inneren Teller aus einem Metallblech und einen äußeren Zahnkranz aus einem vorzugsweise spritzgegossenen Kunststoff auf, wobei an dem inneren Teller ein Stützring vorgesehen ist, an dem die Mitnehmerkörper angreifen können. Damit ist eine mit geringen Toleranzen einfach herstellbare Vorrichtung vorgeschlagen. Gegen Wärmeeinstrahlung seitens einer Reibkupplung kann das Kunststoffzahnrad mittels eines mitlaufenden Schirmblechs geschützt werden.In Another embodiment of the invention, the starter ring a inner plate of a metal sheet and an outer ring gear of a preferably injection-molded plastic, wherein on the inner plate a support ring is provided, on which the driver body can attack. In order to is a simple to manufacture with low tolerances device proposed. Against heat radiation By a friction clutch, the plastic gear by means of a protected shielding sheet metal become.
