Abstract
Description
Die vorliegende Erfindung betrifft ein Hybridgetriebe gemäß den Merkmalen des Patentanspruches 1.The The present invention relates to a hybrid transmission according to the features of claim 1.
Aus dem Stand der Technik sind vielfältige „Parallelhybridvarianten” bekannt. Üblicherweise wird hierbei eine elektrische Maschine zwischen einem Verbrennungsmotor und einem konventionellen Automatikgetriebe auf der Motor- bzw. Getriebe- Welle installiert, die mit einer Trennkupplung oder durch einen Wandler vom Getriebe getrennt werden kann. Üblicherweise handelt es sich bei derartigen Parallelhybridkonzepten um so genannte „Mild-Hybrids”, die aus Kostengründen mit einer elektrischen Maschine geringer Antriebsleistung konzipiert sind, ohne die Möglichkeit, über eine größere Strecke rein elektrisch zu fahren.Out The prior art discloses various "parallel hybrid variants". Usually will Here is an electrical machine between an internal combustion engine and a conventional automatic transmission on the engine or Transmission shaft installed with a disconnect clutch or by a Transducer can be disconnected from the gearbox. Usually it is in such parallel hybrid concepts to so-called "mild hybrids", the cost reasons designed with an electric machine of low drive power are, without the possibility, about one larger route purely electric drive.
Will man mit einem Parallelhybrid rein elektrisch fahren, so ist eine zusätzliche Kupplung zwischen dem Motor und der elektrischen Maschine erforderlich. Ein ruckfreies Zustarten des Verbrennungsmotors mittels der elektrischen Maschine aus dem rein elektrischen Fahrbetrieb heraus ist technisch aufwändig, insbesondere wenn ein Einbrechen des elektrischen Vortriebsmoments verhindert werden soll.Want If you drive with a parallel hybrid purely electric, so is one additional Coupling between the engine and the electric machine required. A smooth start of the internal combustion engine by means of the electric Machine out of pure electric driving is technical consuming, in particular if a collapse of the electrical propulsion torque should be prevented.
Vollhybridkonzepte bieten zusätzlich zu rein elektrischem Fahren auch die erweiterte Funktion eines elektrisch gesteuerten, stufenlosen Getriebes (E-CVT), was eine weitere Verringerung des Kraftstoffverbrauchs ermöglicht. Der technische Aufwand hierfür bei Vollhybridkonzepten ist jedoch sehr hoch.Full hybrid concepts offer additionally to purely electric driving also the advanced function of an electric controlled continuously variable transmission (E-CVT), which is a further reduction of fuel consumption. The technical effort for this in full hybrid concepts, however, is very high.
Eine kostengünstige Auslegung eines Parallelhybridantriebsstrangs kann in der Regel durch die Verwendung einer zusätzlichen Kupplung auch auf die Funktion „rein elektrisches Fahren” mit ausgeschaltetem Verbrennungsmotor erweitert werden. Problematisch hierbei ist, dass während des rein elektrischen Fahrens der Zustart des Verbrennungsmotors durch das Schließen der Kupplung einen „negativen Ruck” im Antriebsstrang und somit Komforteinbußen hervorruft. Um dies zu vermeiden sind auch Parallelhybridkonzepte bekannt, bei denen für den Zustart des Verbrennungsmotors eine separate Motorstartvorrichtung vorgesehen ist. Alternativ zu einer separaten Startvorrichtung kann eine „Kompensation” des Startrucks auch durch eine Auslegung der elektrischen Maschine und des elektrischen Energiespeichers auf eine wesentlich höhere Spitzenlast erreicht werden, als für das rein elektrische Fahren erforderlich ist. Die elektrische Maschine und der elektrische Energiespeicher sind somit grundsätzlich überdimensioniert, was mit zusätzlichen Kosten und zusätzlichem Gewicht verbunden ist.A inexpensive Design of a parallel hybrid powertrain can usually through the use of an additional Clutch also on the function "purely electric driving" with switched off Internal combustion engine to be expanded. The problem here is that while purely electric driving of a service of the internal combustion engine by closing the clutch a "negative Jerk "im Powertrain and thus causes loss of comfort. To this, too Avoid parallel hybrid concepts are known in which for the support the internal combustion engine provided a separate engine starting device is. As an alternative to a separate starting device, a "compensation" of the launch truck also by a design of electric machine and electric Energy storage can be achieved at a much higher peak load, as for pure electric driving is required. The electric machine and the electrical energy storage are thus basically oversized, what with additional Costs and additional Weight is connected.
Aufgabe bzw. Ausgangspunkt der Erfindung ist die Überlegung, ein herkömmliches Automatikgetriebekonzept derart zu modifizieren, dass sich in konstruktiv einfacher Weise ein Hybridantrieb ergibt, der die Funktionalität eines „Vollhybrids” bietet und der einen weitgehend ruckfreien Zustart des Verbrennungsmotors aus dem rein elektrischen Fahrbetrieb heraus ermöglicht und zwar ohne ein separates Zustartaggregat.task or starting point of the invention is the consideration, a conventional Modify automatic transmission concept such that in constructive simply gives a hybrid drive, which provides the functionality of a "full hybrid" and a largely jerk-free support of the internal combustion engine from the purely electric driving out allows and without a separate Zustartaggregat.

The basic principle of the invention is to modify the transmission input, in particular the torque converter in a suitable manner by an electric Machine and a brake to replace.
Konkret weist ein Hybridgetriebe ein erstes mit der elektrischen Maschine gekoppeltes Getriebeelement auf, an dem mindestens ein erstes Planetenrad, insbesondere ein erster Satz Planetenräder, gelagert ist. Bei dem ersten Getriebeelement kann es sich um den Planetenträger des eingangsseitig angeordneten Planetensatzes des ZF 6HP Getriebes handeln.Concrete For example, a hybrid transmission has a first one with the electric machine coupled transmission element on which at least one first planetary gear, in particular a first set planetary gears, is stored. In which first transmission element may be the planet carrier of On the input side arranged planetary gear set of the ZF 6HP transmission act.
Ferner ist ein zweites, mit einem Verbrennungsmotor gekoppeltes, hohlradartiges Getriebeelement vorgesehen, das mit dem ersten Planetenrad bzw. mit dem ersten Satz Planetenräder kämmt. Das zweite Getriebeelement kann ohne Trennkupplung direkt mit einer Kurbelwelle des Verbrennungsmotors gekoppelt sein.Further is a second, coupled to an internal combustion engine, Hohlradartiges Gear element provided with the first planetary gear or with the first set of planetary gears combs. The second transmission element can without disconnect directly with a Be coupled crankshaft of the internal combustion engine.
Bereits aus dem ZF6HP Getriebe bekannt ist die Verwendung eines zweiten, doppelten Planetensatzes, der auch als Ravigneaux-Satz bezeichnet wird. Dementsprechend ist gemäß der Erfindung ein drittes, planetenträgerartiges Getriebeelement vorgesehen, an dem mindestens ein zweites Planetenrad, insbesondere ein zweiter Satz Planetenräder, und mindestens ein drittes Planetenrad, insbesondere ein dritter Satz Planetenräder, gelagert ist.Already known from the ZF6HP transmission is the use of a second, double planetary gear set, which is also called Ravigneaux set. Accordingly, according to the invention a third, planet carrier-like Gear element provided on the at least one second planetary gear, in particular a second set of planet gears, and at least a third one Planetary gear, in particular a third set planetary gears, stored is.
Darüber hinaus ist ein viertes, sonnenradartiges Getriebeelement vorgesehen, mit dem das mindestens eine zweite oder dritte Planetenrad kämmt.Furthermore a fourth sun gear-like transmission element is provided, with which meshes with the at least one second or third planetary gear.
Ein fünftes, hohlradartiges Getriebeelement kämmt mit dem mindestens einen zweiten oder dritten Planetenrad und bildet ein Abtriebselement des Getriebes.One fifth, Hohlradartiges gear element meshes with the at least one second or third planetary gear and forms an output element of the transmission.
Ferner ist eine erste und eine zweite Kupplung vorgesehen. Wenn die erste Kupplung geschlossen ist, sind das erste und das vierte Getriebeelement miteinander drehgekoppelt. Durch Schließen der zweiten Kupplung werden das zweite und das dritte Getriebeelement miteinander drehgekoppelt.Further, a first and a second Kupp provided. When the first clutch is closed, the first and fourth gear members are rotationally coupled together. By closing the second clutch, the second and the third transmission element are rotationally coupled together.
