Abstract
Description
Die Erfindung betrifft ein leistungsverzweigtes CVT-Getriebe.The The invention relates to a power split CVT transmission.
CVT-Getriebe,
d. h. Getriebe mit stufenlos veränderbarer Übersetzung,
finden zunehmend Verwendung in modernen Kraftfahrzeugen. Um den Übersetzungsbereich,
d. h. die Spreizung, des Getriebes zu vergrößern und/oder den im Allgemeinen als
Reibgetriebe, insbesondere Kegelscheibenumschlingungsgetriebe ausgebildeten
Variator zu entlasten, werden solche stufenlosen Getriebe mit Leistungsverzweigung
ausgebildet, wie beispielsweise in der
Der Erfindung liegt die Aufgabe zugrunde, ein leistungsverzweigtes CVT-Getriebe zu schaffen, das trotz eines hohen Anfahrmoments mit einem Variator mit geringerer Drehmomentübertragungsfähigkeit auskommt.Of the Invention is based on the object, a power-split CVT transmission to create, despite a high starting torque with a variator with lower torque transmission capability gets along.
Diese Aufgabe wird mit einem leistungsverzweigten CVT-Getriebe gelöst, das enthält eine Eingangswelle und Ausgangswelle, ein Verteilergetriebe, das das Drehmoment der Eingangswelle auf zwei Drehmomentübertragungspfade verteilt, von denen einer mit der Ausgangswelle verbunden ist, und einen die Drehmomentübertragungspfade miteinander verbindenden Variator, wobei in einem der Drehmomentübertragungspfade zwischen dem Verteilergetriebe und dem Variator ein Anfahrelement angeordnet ist.These Task is solved with a power-split CVT transmission, the contains an input shaft and output shaft, a transfer case, the the torque of the input shaft on two torque transmission paths distributed, one of which is connected to the output shaft, and one the torque transmission paths interconnecting variator, wherein in one of the torque transmission paths between the transfer case and the variator a starting element is arranged.
Bei dem erfindungsgemäßen leistungsverzweigten CVT-Getriebe wird trotz Erhöhung des Anfahrmoments mittels dem Anfahrelement der Variator nicht mit einem erhöhten Moment belastet, so dass er entsprechend kostengünstiger und mit kleinem Bauraum ausgebildet werden kann.at the power-split according to the invention CVT transmission is in spite of increase the starting torque by means of the starting element of the variator not with an increased Moment burdened, so that he correspondingly more cost-effective and with a small space can be trained.
Mit Vorteil ist das Anfahrelement als hydrodynamischer Wandler ausgebildet.With Advantage is the starting element designed as a hydrodynamic converter.
Der hydrodynamische Wandler enthält bevorzugt eine Überbrückungskupplung.Of the hydrodynamic converter contains preferably a lock-up clutch.
Ebenfalls vorteilhaft ist das Anfahrelement als elektrischer Wandler ausgebildet, d.h. in Form einer als Generator betriebenen E-Maschine und einer als Motor betriebenen E-Maschine, die elektrische Leistung austauschen.Also Advantageously, the starting element is designed as an electrical converter, i.e. in the form of an electric machine operated as a generator and one as Motor powered electric motor, which exchange electrical power.
Der elektrische Wandler enthält bevorzugt eine Überbrückungskupplung. Im überbrückten Zustand stellt der elektrische Wandler eine große Gesamt-E-Maschine dar, mit der die üblichen Hybrid-Funktionen wahrgenommen werden können wie Rekuperieren, Boosten, Starten.Of the contains electrical converter preferably a lock-up clutch. In bridged condition represents the electrical converter is a large total electric machine, with the usual Hybrid functions can be perceived as recuperation, boosting, Start.
Bei einer bevorzugten Ausführungsform des erfindungsgemäßen Getriebes ist der den Wandler enthaltende Drehmomentübertragungspfad mit der Ausgangswelle verbunden.at a preferred embodiment of the transmission according to the invention is the torque transfer path containing the transducer with the output shaft connected.
Vorteilhafterweise ist der den Wandler enthaltende Drehmomentübertragungspfad über eine Übersetzungsstufe mit der Ausgangswelle verbunden.advantageously, is the torque transmission path containing the transducer via a translation stage connected to the output shaft.
Weiter ist vorteilhafterweise in dem nicht mit dem Wandler enthaltenden Drehmomentübertragungspfad zwischen dem Verteilergetriebe und dem Variator eine Übersetzungsstufe enthalten.Further is advantageously in the non-containing with the transducer Torque transmission path between the transfer case and the variator a translation stage contain.
Das Verteilergetriebe kann beispielsweise als ein Planetengetriebe ausgebildet sein.The Transfer case, for example, designed as a planetary gear be.
Zur doppelten Nutzung der Spreizung des Variators kann wahlweise der eine oder der andere Drehmomentübertragungspfad mit der Ausgangswelle verbindbar sein.to dual use of the spread of the variator may optionally be the one or the other torque transmission path be connectable to the output shaft.
Die Erfindung wird im Folgenden anhand schematischer Zeichnungen beispielsweise und mit weiteren Einzelheiten erläutert.The Invention will be described below with reference to schematic drawings, for example and explained in more detail.
