Description
Die Erfindung betrifft ein Getriebesystem mit integrierter elektrischer Maschine, mit einem Getriebe mit Freilauf und einem daran angebundenen Planetengetriebe. Weiterhin betrifft die Erfindung ein Verfahren zum Betrieb eines solchen Getriebesystems, welches sowohl in einem elektrisch gesteuerten, stufenlosen Getriebe EVT (Electric Variable Transmission), als auch mit festen Gängen in einem Parallelhybridmodus betrieben werden kann.The invention relates to a transmission system with integrated electric machine, with a transmission with freewheel and an attached planetary gear. Furthermore, the invention relates to a method for operating such a transmission system, which can be operated both in an electrically controlled, continuously variable transmission EVT (Electric Variable Transmission), as well as fixed gears in a parallel hybrid mode.

Aus der
Mit der elektrischen Aktuatorik ist das Doppelkupplungsgetriebe in der Lage, bei abgetrenntem Verbrennungsmotor automatisch zu kuppeln und zu schalten. Es ist somit vorbereitet für ein Start/Stopp-System und eine erweiterte Segelfunktion, bei der das Fahrzeug bei abgekoppeltem Verbrennungsmotor frei rollt. Die elektrische Aktuatorik ermöglicht darüber hinaus die einfache Hybridisierung des Getriebes, durch die zusätzliche E-Maschine.With the electric actuator, the dual-clutch transmission is able to automatically engage and disengage when the internal combustion engine is disconnected. It is thus prepared for a start / stop system and an extended sailing function in which the vehicle rolls freely with the combustion engine disconnected. The electrical actuator also allows easy hybridization of the transmission, through the additional electric motor.

Wegen seiner zwei Betriebsarten, von denen eine für niedrige und eine für hohe Geschwindigkeiten optimiert ist, wird das auf einem elektrisch gesteuerten, stufenlosen Getriebe EVT, Electric Continuously Variable Transmission, basierende System als Two-Mode-Hybrid-System bezeichnet. Ein EVT-Modus mit Minusplanetensatz ist aus dem Toyota Prius bekannt.Because of its two modes of operation, one optimized for low and one for high speeds, the EVT (Electric Continuously Variable Transmission) based system is referred to as a two-mode hybrid system. An EVT mode with minus planetary gear set is known from the Toyota Prius.
Das Hybridgetriebe verfügt zusätzlich über vier Gänge mit festem Übersetzungsverhältnis, sodass ein hoher Wirkungsgrad und eine optimale Leistungs- und Ladeausbeute erzielt werden kann. Die integrierten Elektromotoren werden für Beschleunigungsvorgänge wie auch regeneratives Bremsen genutzt.The hybrid transmission also has four gears with a fixed gear ratio, so that a high efficiency and optimum performance and loading yield can be achieved. The integrated electric motors are used for acceleration as well as regenerative braking.
In mechanischer Hinsicht und in Bezug auf die Gesamtgröße ist das Vollhybrid-System mit einem herkömmlichen Automatikgetriebe vergleichbar, kann aber mit stufenloser Übersetzung oder in einem der vier Gänge betrieben werden.Mechanically and in terms of overall size, the full hybrid system is comparable to a conventional automatic transmission, but can be operated with continuously variable transmission or in one of the four gears.
Ein Antriebsstrang für einen Parallelhybrid setzt sich aus einem Verbrennungsmotor, einem Elektromotor, einem Getriebe und einem Differential zusammen. Zwischen Getriebe und Verbrennungsmotor befindet sich eine automatisierte Trennkupplung. Mit Hilfe der automatisierten Trennkupplung kann das Fahrzeug in den Betriebsmodi „Elektrisch Fahren“ und „Rekuperation“ ohne das hohe Schleppmoment des Verbrennungsmotors betrieben werden kann, indem diese geöffnet wird.A powertrain for a parallel hybrid is composed of an internal combustion engine, an electric motor, a transmission and a differential. Between transmission and combustion engine is an automated disconnect clutch. With the help of the automated separating clutch, the vehicle can be operated in the operating modes "electric driving" and "recuperation" without the high drag torque of the internal combustion engine by opening it.
Es ist Aufgabe der Erfindung ein Getriebesystem mit integrierter elektrischer Maschine zu schaffen, das für den Betrieb im EVT Modus, einen rein elektrischen Betrieb und als Parallelhybrid optimiert ist.It is an object of the invention to provide a transmission system with integrated electric machine, which is optimized for operation in EVT mode, a purely electrical operation and as a parallel hybrid.
Die Aufgabe wird gelöst mit einem Getriebesystem mit integrierter elektrischer Maschine, mit einem Getriebe mit Freilauf und einem daran angebundenen Planetengetriebe sowie einer Kupplung entweder zur Trennung des Getriebesystems von einem Verbrennungsmotor oder zur Trennung des Getriebes von dem angebundenen Planetengetriebe und einem Stirnrad, das die elektrische Maschine mit einem Steg des Planetengetriebes verbindet, wobei eine zweite Kupplung zur Verblockung des Planetengetriebes eingesetzt ist und der Abtrieb mit einem Hohlrad des Planetengetriebes verbunden ist.The object is achieved with a transmission system with integrated electric machine, with a transmission with freewheel and a planetary gear connected thereto and a clutch either for separating the transmission system of an internal combustion engine or for separating the transmission from the connected planetary gear and a spur gear, the electric machine connects to a web of the planetary gear, wherein a second clutch is used for blocking the planetary gear and the output is connected to a ring gear of the planetary gear.
Die vorliegende Erfindung vereint die Vorteile und Funktionen mehrerer Betriebszustände nämlich eines EVT-Modus, eines Parallelhybridmodus, einen rein elektrischen Modus und prinzipiell auch einen rein verbrennungsmotorischen Modus in einem Getriebesystem.The present invention combines the advantages and functions of several operating states namely an EVT mode, a parallel hybrid mode, a purely electrical mode and, in principle, a pure combustion engine mode in a transmission system.
In einer vorteilhaften Ausführungsform ist das Getriebe ein Vorgelegegetriebe.In an advantageous embodiment, the transmission is a countershaft transmission.
Vorteilhafterweise verblockt die Kupplung durch Kopplung des Stegs mit dem Hohlrad das Planetengetriebe oder durch Kopplung des Stegs mit einer Sonne das Planetengetriebe oder durch Kopplung einer Sonne mit dem Hohlrad das Planetengetriebe.Advantageously, the coupling is blocked by coupling the web with the ring gear planetary gear or coupling the web with a sun the planetary gear or by coupling a sun with the ring gear planetary gear.
Der Vorteil besteht darin, zwei elektrische Gänge mit einem Planetengetriebe und Beschaltung des Planetengetriebes darzustellen. Die Sonne des Planetengetriebes wird dann nicht einfach mit einer Bremse festgesetzt oder freigegeben, sondern mit einer Kupplung wahlweise mit einem klassischen 4-Gang Vorgelegegetriebe gekuppelt oder getrennt. Prinzipiell ist auch eine Kopplung eines jeden anderen Getriebes mit schaltbaren Gängen an die Sonne denkbar.The advantage is to represent two electrical gears with a planetary gear and wiring of the planetary gear. The sun of the Planetary gear is then not simply set or released with a brake, but coupled with a clutch optional with a classic 4-speed countershaft transmission or separated. In principle, a coupling of any other transmission with switchable gears to the sun is conceivable.
Es ist von Vorteil, dass der Freilauf in einem Gehäuse des Getriebesystems fest eingebaut ist und ein Rückwärtsdrehen einer Ausgangswelle des Getriebes verhindert.It is advantageous that the freewheel is fixedly mounted in a housing of the transmission system and prevents reverse rotation of an output shaft of the transmission.
Es ist von Vorteil, dass das Getriebesystem einen Eingangswelle und mindestens einen Ausgangswelle aufweist. Auch ein Getriebesystem mit zwei Ausgangswellen kann zur Lösung der Aufgabe eingesetzt werden.It is advantageous that the transmission system has an input shaft and at least one output shaft. Also, a transmission system with two output shafts can be used to solve the problem.
Für eine Bauraumoptimierung ist es von Vorteil, dass das Getriebesystem mindestens eine weitere Welle für den Abtrieb aufweist.For a space optimization, it is advantageous that the transmission system has at least one further shaft for the output.
Vorteilhafterweise ist das Planetengetriebe ein Plusgetriebe.Advantageously, the planetary gear is a plus gear.
Die Anordnung der zweiten Kupplung erfolgt so dass die Ausgangswelle das Planetengetriebe und die Kupplung koaxial zueinander angeordnet sind, was Bauteile und Platz einspart.The arrangement of the second clutch is made so that the output shaft, the planetary gear and the clutch are arranged coaxially with each other, which saves components and space.

- - Second electrical gear with blocked planetary gear set
- - first electric gear forward with gear ratio from bridge to ring gear and the sun blocked by the freewheel,
- - First electrical gear backwards with gear ratio of bridge to ring gear and sun blocked by lock in the transmission.
Es ist von Vorteil, dass die Sperre im Getriebe durch Einlegen von zwei Gängen erfolgt.It is advantageous that the lock in the transmission is made by inserting two gears.
Das erfindungsgemäße Verfahren dient auch zum Betrieb eines Getriebesystems mit integrierter elektrischer Maschine, mit einem Getriebe, wobei ein Verbrennungsmotor an das Getriebe angebunden oder anbindbar ist, und mit einem Planetengetriebe aufweisend ein erstes Element, ein zweites Element und ein drittes Element, wobei das Getriebe an das erste Element des Planetengetriebes angebunden ist, wobei die elektrische Maschine an das zweite Element des Planetengetriebes angebunden oder anbindbar ist, wobei das dritte Element des Planetengetriebes mit einem Abtrieb verbunden ist, wobei, das Getriebe in einen blockierten Zustand versetzt wird, um einen elektrischen Gang einzurichten, derart, dass sich ein von der elektrischen Maschine hervorgerufenes Drehmoment an dem blockierten Getriebe abstützt.The inventive method is also used to operate a transmission system with an integrated electric machine, with a transmission, wherein an internal combustion engine is connected to the transmission or connectable, and having a planetary gear having a first element, a second element and a third element, wherein the transmission the first element of the planetary gear is connected, wherein the electric machine is connected or connectable to the second element of the planetary gear, wherein the third element of the planetary gear is connected to an output, wherein the transmission is placed in a locked state to an electric gear set up such that a caused by the electric machine torque is supported on the locked transmission.

Um den elektrischen Gang einzulegen, muss sich das Drehmoment an dem blockierten Getriebe abstützen. Um das Getriebe zu blockieren sind unterschiedliche Verfahren denkbar. Zum einem kann das Getriebe durch Einlegen von zwei Gängen gleichzeitig blockiert werden.To engage the electric gear, the torque must be supported on the locked gear. To block the transmission different methods are conceivable. On the one hand, the transmission can be blocked simultaneously by inserting two gears.
Weiterhin ist der Einsatz eines Freilaufs möglich, der das Getriebe in eine Drehrichtung blockiert.Furthermore, the use of a freewheel is possible, which blocks the transmission in one direction.
Ansonsten kann auch immer einen Bremse verbaut werden.Otherwise, always a brake can be installed.
