Description
Die vorliegende Erfindung betrifft ein leistungsverzweigtes stufenloses Automatgetriebe für ein Kraftfahrzeug gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a power split continuously variable automatic transmission for a motor vehicle according to the generic term of claim 1.
Aus dem Stand der Technik sind stufenloses Automatgetriebe

bekannt. Derartige Getriebe weisen den Vorteil gegenüber Stufenautomatgetrieben
auf, dass ein niedriger Kraftstoffverbrauch bei erhöhtem Fahrkomfort
und besserem Beschleunigungsverhalten erzielt wird. Beispielsweise offenbart

Des weiteren ist aus der 29 48 194
C2 ein Getriebe mit stufenlos einstellbarem Übersetzungsverhältnis bekannt,
bei dem ein Antriebsscheibensatz eines Kegelscheiben-Umschlingungsgetriebes auf
einer ersten Welle koaxial zum Antrieb angeordnet ist, wobei der
Abtriebsscheibensatz auf einer zweiten parallelen Welle angeordnet
ist, welche mit einem Differentialgetriebe verbunden ist. Hierbei führt ein
erstes Planetengetriebe von dem Abtriebsscheibensatz zum Differentialgetriebe,

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ausgehend von dem genannten Stand der Technik ein leistungsverzweigtes stufenloses Automatgetriebe anzugeben, welches eine sehr kompakte Bauweise aufweist. Des weiteren soll eine hohe Getriebespreizung realisiert werden sowie ein hoher Wirkungsgrad und ein geringer Kraftstoffverbrauch erzielt werden.The present invention lies based on the task, based on the prior art mentioned to specify a power-split continuously variable automatic transmission, which has a very compact design. Furthermore should a high gear spread can be realized as well as a high efficiency and low fuel consumption can be achieved.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.This task is due to the characteristics of claim 1 solved. Further configurations and advantages emerge from the subclaims.
Demnach wird ein stufenloses Fahrzeuggetriebe mit einem stufenlosen Getriebe bzw. Variator endlicher Spreizung und drei Fahrbereichen vorgeschlagen, wobei zwei Fahrbereiche als leistungsverzweigte Bereiche ausgelegt sind, bei denen nur ein Teil der Eingangsleistung über das stufenlose Getriebe an die Abtriebswelle geleitet wird. Beide Leistungsflüsse der leistungsverzweigten Bereiche werden in einem Summierdifferential, das vorzugsweise als Planetensatz ausgebildet ist, wieder aufsummiert.Accordingly, a continuously variable vehicle transmission with a continuously variable transmission or variator with finite spread and three driving ranges proposed, two driving ranges as power-split areas are designed in which only a part the input power over the continuously variable transmission is directed to the output shaft. Both power flows of the power-split areas are in a summing differential, which is preferably designed as a planetary set, added up again.
Hierbei unterscheiden sich die beiden leistungsverzweigten Bereiche durch unterschiedliche Übersetzungen im formschlüssig mechanischen Teil.Here the two differ service-split areas through different translations im positive mechanical part.
Erfindungsgemäß sind die Übersetzungen und die Standgetriebeübersetzungen des Summierdifferentials so gewählt, dass im ersten Fahrbereich eine Vorwärts- und Rückwärtsfahrt durch Leistungsverzweigung sowie ein kraftschlüssiges Anfahren möglich ist. Zudem kann durch die Realisierung einer Geared-Neutral-Charakteristik die Notwendigkeit eines zusätzlichen Rückwärtsganges entfallen, da die Verstellung des stufenlosen Getriebes die Umschaltung zwischen Vorwärts- und Rückwärtsgang übernimmt. Zum Anfahren wird keine zusätzliche Anfahrkupplung benötigt.The translations and the stationary gear ratios are according to the invention of the summing differential selected that in the first driving range a forward and backward drive through power split as well as a non-positive Starting possible is. In addition, by implementing a geared-neutral characteristic the need for an additional reverse gear omitted, because the adjustment of the continuously variable transmission the switching between forward and reverse gear takes over. There is no additional for starting Start clutch required.
Für den zweiten Bereich ist gemäß der Erfindung keine Leistungsverzweigung vorgesehen; die komplette Leistung wird über das stufenlose Getriebe an die Abtriebswelle über das in diesem Fall im Blockbetrieb umlaufende Summierdifferential geleitet. Im dritten Bereich, der vorteilhafterweise als Overdrive-Bereich ausgelegt ist, wird durch die Leistungsverzeigung nur ein geringer Teil der Leistung über den Variator geleitet.For the second area is according to the invention no power split planned; the complete performance is over that stepless transmission to the output shaft via in this case in block mode revolving summing differential directed. In the third area, the is advantageously designed as an overdrive area the performance record only a small part of the performance over the Headed variator.
Durch die erfindungsgemäße Konzeption wird der Wirkungsgrad erhöht und der Kraftstoffverbrauch erheblich reduziert. Außerdem wird das stufenlose Getriebe, insbesonde re im Overdrive-Bereich gering belastet, was zu einer Erhöhung der Lebensdauer führt.The inventive concept is the efficiency increases and significantly reduced fuel consumption. Besides, will the continuously variable transmission, especially low in the overdrive range burdened, leading to an increase the lifespan leads.
Die Umschaltungen zwischen den Bereichen finden bei synchronen Drehzahlen der beteiligten Schaltelemente statt und verlaufen ohne Zugkrafteinbruch, was zur Erhöhung des Komforts beiträgt; dadurch können Bereichsumschaltungen ohne Übersetzungsveränderung realisiert werden.Find the switches between areas at synchronous speeds of the switching elements involved instead and run without loss of traction, which contributes to increased comfort; thereby can Area switching without changing the translation will be realized.
Des weiteren wird durch die Verwendung nur eines Summierdifferentials für alle Bereiche sowie durch die Geared-Neutral-Charakteristik der Bauaufwand reduziert.Furthermore, through the use only one summing differential for all areas as well as the construction effort due to the geared-neutral characteristic reduced.
Die Erfindung wird im Folgenden anhand der beigefügten Figuren näher erläutert.The invention is explained below the attached Figures closer explained.
