Abstract
Ein für den Antriebsstrang eines Kraftfahrzeugs geeigneter Schwingungstilger umfasst zwei Schwungscheiben, nämlich eine Primärschwungscheibe und eine Sekundärschwungscheibe, sowie zwei Planetengetriebe, welche jeweils mit einer der Schwungscheiben sowie miteinander gekoppelt sind, und einen über eines der Planetengetriebe angetriebenen Generator, welcher zur Erzeugung elektrischer Energie aus Relativbewegungen zwischen den beiden Schwungscheiben ausgebildet ist.A suitable for the drive train of a motor vehicle vibration absorber comprises two flywheels, namely a primary flywheel and a secondary flywheel, and two planetary gear, which are each coupled to one of the flywheels and each other, and a driven via one of the planetary gear generator, which for generating electrical energy from relative movements is formed between the two flywheels.
Description
Die Erfindung betrifft einen Schwingungstilger für den Antriebsstrang eines Kraftfahrzeugs, welcher zwei begrenzt gegeneinander verdrehbare Schwungscheiben aufweist.The invention relates to a vibration damper for the drive train of a motor vehicle, which has two limited against each other rotatable flywheels.

Der Erfindung liegt die Aufgabe zugrunde, einen gegenüber dem genannten Stand der Technik weiterentwickelten Schwingungstilger für den Antriebsstrang eines Kraftfahrzeugs anzugeben, welcher sich durch eine besonders effiziente Schwingungsdämpfung bei gleichzeitig energetisch günstigem Verhalten auszeichnet.The invention has for its object to provide a comparison with the cited prior art further developed vibration absorber for the drive train of a motor vehicle, which is characterized by a particularly efficient vibration damping at the same time energetically favorable behavior.
Diese Aufgabe wird erfindungsgemäß gelöst durch einen Schwingungstilger mit den Merkmalen des Anspruchs 1. Der Schwingungstilger umfasst zwei begrenzt gegeneinander verdrehbare Schwungscheiben, nämlich eine Primärschwungscheibe und eine Sekundärschwungscheibe, wobei mit jeder der Schwungscheiben ein Planetengetriebe gekoppelt ist. Ebenso sind die beiden Planetengetriebe miteinander gekoppelt. Eines der Planetengetriebe, insbesondere das sekundärseitige Planetengetriebe, treibt einen Generator an, welcher zur Erzeugung elektrischer Energie aus Relativbewegungen zwischen den beiden Schwungscheiben ausgebildet ist. Relativschwingungen zwischen den beiden Schwungscheiben werden somit gedämpft und zugleich zur Erzeugung elektrischer Energie genutzt. This object is achieved by a vibration damper with the features of
Gegenüber einem herkömmlichen, landläufig auch als Lichtmaschine bezeichneten Generator eines Kraftfahrzeugs hat der Schwingungstilger zusätzlich zu seinen schwingungstilgenden Eigenschaften den besonderen Vorteil, dass er gerade bei niedrigen Drehzahlen des Verbrennungsmotors eine hohe Ausbeute liefert. Der herkömmliche Generator kann dementsprechend schwächer ausgelegt werden oder sogar gänzlich entfallen. Aufgrund der platzsparenden Bauweise der Planetengetriebe erfordert der Schwingungstilger im Antriebsstrang im Vergleich zu einem herkömmlichen Antriebsstrang mit Zweimassenschwungrad kaum zusätzlichen Bauraum. Der Schwingungstilger ist besonders für Kraftfahrzeuge mit Hubkolbenmotoren mit wenigen Zylindern, beispielsweise drei oder zwei Zylindern, geeignet. Der Schwingungstilger ist mit Getrieben beliebiger Bauart, beispielsweise Handschaltgetrieben oder Doppelkupplungsgetrieben, kombinierbar. Ebenso ist der Schwingungstilger für beliebige Einbaulagen des Verbrennungsmotors, etwa längs eingebauter Motor vorn, quer eingebauter Motor vorn oder Heckmotor, geeignet. Auch Fahrzeuge mit hydraulischem Drehmomentwandler sind mit dem Schwingungstilger ausrüstbar.Compared to a conventional, commonly referred to as an alternator generator of a motor vehicle, the vibration absorber in addition to its vibration damping properties has the particular advantage that it delivers a high yield, especially at low speeds of the engine. The conventional generator can be designed accordingly weaker or even eliminated altogether. Due to the space-saving design of the planetary gear, the vibration damper in the drive train requires little additional space compared to a conventional powertrain with dual-mass flywheel. The vibration damper is particularly suitable for motor vehicles with reciprocating engines with few cylinders, for example three or two cylinders. The vibration damper can be combined with transmissions of any design, for example manual transmissions or dual-clutch transmissions. Likewise, the vibration damper is suitable for any mounting position of the engine, such as longitudinally mounted engine front, transversely mounted engine front or rear engine. Also vehicles with hydraulic torque converter can be equipped with the vibration damper.
Gemäß einer ersten möglichen Ausführungsform weist das erste, das heißt primärseitige Planetengetriebe des Schwingungstilgers ein fest mit der Primärschwungscheibe gekoppeltes Sonnenrad und ein nicht rotierbares Hohlrad auf. Die an einem Planetenträger gelagerten Planetenräder des ersten Planetengetriebes sind fest mit den Planetenrädern des zweiten, sekundärseitigen Planetengetriebes gekoppelt. Das Sonnenrad des zweiten Planetengetriebes ist fest mit der Sekundärscheibe des Schwingungstilgers gekoppelt. Der Generator ist über das Hohlrad des zweiten Planetengetriebes angetrieben.According to a first possible embodiment, the first, that is primary-side planetary gear of the vibration absorber on a fixedly coupled to the primary flywheel sun gear and a non-rotatable ring gear. The mounted on a planet carrier planetary gears of the first planetary gear are fixedly coupled to the planetary gears of the second, secondary-side planetary gear. The sun gear of the second planetary gear is fixedly coupled to the secondary disc of the vibration absorber. The generator is driven via the ring gear of the second planetary gear.
Gemäß einer zweiten möglichen Ausführungsform ist mit den beiden Schwungscheiben des Schwingungstilgers jeweils ein Hohlrad eines Planetengetriebes fest verbunden. Das Sonnenrad des ersten Planetengetriebes ist hierbei nicht rotierbar im Antreibsstrang angeordnet. Die Planetenräder der beiden Planetengetriebe sind wiederum fest miteinander gekoppelt. Der Generator ist in diesem Fall jedoch über das Sonnenrad des zweiten Planetengetriebes angetrieben. In beiden Ausführungsformen kann der Generator über ein Getriebe, insbesondere Stirnradgetriebe, mit dem sekundarseitigen Planetengetriebe gekoppelt sein. Zusätzlich oder alternativ kann der Antrieb des Generators über einen Freilauf erfolgen, so dass der Generator durch die Anordnung aus den Planetengetrieben lediglich beschleunigt, jedoch nicht gebremst werden kann.According to a second possible embodiment, in each case a ring gear of a planetary gear is fixedly connected to the two flywheels of the vibration. The sun gear of the first planetary gear is not rotatably arranged in the drive train here. The planetary gears of the two planetary gears are in turn firmly coupled together. However, the generator is driven in this case via the sun gear of the second planetary gear. In both embodiments, the generator via a transmission, in particular spur gear, be coupled to the secondary-side planetary gear. Additionally or alternatively, the drive of the generator via a freewheel, so that the generator only accelerated by the arrangement of the planetary gears, but can not be braked.
