Description
Die Erfindung betrifft ein Hybridgetriebe für ein Kraftfahrzeug, mit einer elektrischen Maschine, die eine Rotorwelle aufweist, und einem Getriebe zum Schalten von mehreren Gängen, das eine Getriebeeingangswelle mit einem ersten Zahnrad aufweist, die mit einer Antriebswelle einer Kraftfahrzeugantriebseinrichtung drehfest verbindbar ist. Außerdem betrifft die Erfindung ein Kraftfahrzug mit einem solchen Hybridgetriebe.The invention relates to a hybrid transmission for a motor vehicle, comprising an electric machine having a rotor shaft, and a transmission for switching multiple gears, which has a transmission input shaft with a first gear, which is rotatably connected to a drive shaft of a motor vehicle drive device. In addition, the invention relates to a motor vehicle with such a hybrid transmission.
Aus dem Stand der Technik ist eine Vielzahl von unterschiedlichen Hybridgetrieben bekannt, die in Kraftfahrzeugen eingesetzt werden. Den Hybridgetrieben gemein ist, dass sie eine elektrische Maschine und ein Getriebe zum Schalten von mehreren Gängen aufweisen. Die bekannten Ausführungen unterscheiden sich voneinander unter anderem hinsichtlich der Anordnung und Ankopplung der elektrischen Maschine mit einer Getriebeeingangswelle des Getriebes. Dabei weisen die bekannten Ausführungen oftmals den Nachteil auf, dass bei der Ankopplung der elektrischen Maschine mit der Getriebeeingangswelle viel Bauraum benötigt wird. Der Bauraum steht jedoch oftmals nicht zur Verfügung, so dass die Ankopplung der elektrischen Maschine mit der Getriebeeingangswelle umständlich oder manchmal nicht möglich ist.From the prior art, a variety of different hybrid transmissions are known, which are used in motor vehicles. The hybrid transmissions have in common that they have an electric machine and a gearbox for switching multiple gears. The known designs differ from each other inter alia with regard to the arrangement and coupling of the electric machine with a transmission input shaft of the transmission. In this case, the known embodiments often have the disadvantage that in the coupling of the electric machine with the transmission input shaft much space is needed. However, the space is often not available, so that the coupling of the electric machine with the transmission input shaft is cumbersome or sometimes not possible.
Die Aufgabe der Erfindung besteht daher darin, ein Hybridgetriebe anzugeben, bei dem die Ankopplung der elektrischen Maschine mit der Getriebeeingangswelle des Getriebes wenig Bauraum benötigt.The object of the invention is to provide a hybrid transmission in which the coupling of the electric machine with the transmission input shaft of the transmission requires little space.
Diese Aufgabe wird durch ein Hybridgetriebe der eingangs genannten Art gelöst, das gekennzeichnet ist durch ein zweites Zahnrad, das in Eingriff mit dem ersten Zahnrad ist und mit der Rotorwelle triebtechnisch verbunden ist.This object is achieved by a hybrid transmission of the type mentioned, which is characterized by a second gear which is in engagement with the first gear and is connected to the rotor shaft drive technology.
Das erfindungsgemäße Hybridgetriebe weist den Vorteil auf, dass durch das zweite Zahnrad ein radialer Abstand zwischen der Rotorwelle der elektrischen Maschine und der Getriebeeingangswelle überbrückt werden kann. Dabei benötigt das zweite Zahnrad in axialer Richtung nicht viel Bauraum, so dass die Ankopplung der elektrischen Maschine mit der Getriebeeingangswelle auch bei Hybridgetrieben möglich ist, bei denen in axialer Richtung wenig Bauraum besteht.The hybrid transmission according to the invention has the advantage that a radial distance between the rotor shaft of the electric machine and the transmission input shaft can be bridged by the second gear. In this case, the second gear in the axial direction does not require much space, so that the coupling of the electric machine with the transmission input shaft is also possible in hybrid transmissions, where there is little space in the axial direction.
Unter einer Welle ist nicht ausschließlich ein beispielsweise zylindrisches, drehbar gelagertes Maschinenelement zur Übertragung von Drehmomenten zu verstehen, sondern vielmehr sind hierunter auch allgemeine Verbindungselemente zu verstehen, die einzelne Bauteile oder Elemente miteinander verbinden, insbesondere Verbindungselemente, die mehrere Bauteile oder Elemente drehfest miteinander verbinden.Under a shaft is not exclusive to understand, for example, a cylindrical, rotatably mounted machine element for transmitting torque, but this is also general connecting elements to understand that connect individual components or elements together, in particular connecting elements that connect a plurality of components or elements rotation with each other.
Als drehfeste Verbindung wird eine Verbindung zwischen zwei Bauteilen verstanden, die derart ausgebildet und angeordnet ist, dass die beiden, miteinander verbundenen Bauteile stets die gleiche Drehzahl und Drehrichtung aufweisen. Dies ist nicht der Fall, wenn beispielsweise zwischen den beiden miteinander verbundenen Bauteilen ein Schaltelement angeordnet ist, das sich im geöffneten Zustand befindet. Die drehfeste Verbindung kann beispielsweise durch eine Steckverzahnung realisiert werden.As a rotationally fixed connection, a connection between two components is understood, which is designed and arranged such that the two interconnected components always have the same speed and direction of rotation. This is not the case if, for example, between the two interconnected components, a switching element is arranged, which is in the open state. The rotationally fixed connection can be realized for example by a spline.
Die Richtungsangaben „axial“ und „radial“ beziehen sich, sofern nichts Gegenteiliges genannt ist, auf eine Mittelachse des Hybridgetriebes, insbesondere auf eine Mittelachse der Getriebeeingangswelle.The directions "axial" and "radial" relate, unless otherwise stated, to a central axis of the hybrid transmission, in particular to a central axis of the transmission input shaft.
Bei einer besonderen Ausführung kann das zweite Zahnrad achsparallel und/oder in radialer Richtung versetzt zu der Rotorwelle und/oder zu dem ersten Zahnrad angeordnet sein. Das erste Zahnrad und/oder das zweite Zahnrad kann eine Außenverzahnung aufweisen. Die triebtechnische Verbindung zwischen der Rotorwelle und dem ersten Zahnrad kann ein Zugmittel aufweisen. Ein Zugmittel kann beispielsweise eine Kette oder ein Riemen sein. Bei einer Ausführung des Zugmittels als Kette kann die Rotorwelle ein Kettenrad aufweisen, das mit der Kette formschlüssig verbunden ist.In a particular embodiment, the second gear may be arranged axially parallel and / or offset in the radial direction to the rotor shaft and / or to the first gear. The first gear and / or the second gear may have an outer toothing. The drive technical connection between the rotor shaft and the first gear may have a traction means. A traction means may be for example a chain or a belt. In one embodiment of the traction means as a chain, the rotor shaft may have a sprocket which is positively connected to the chain.
Das Hybridgetriebe kann ein drittes Zahnrad aufweisen. Das dritte Zahnrad kann einen Teilbereich mit einer Verzahnung aufweisen, die mit einer Verzahnung des zweiten Zahnrads kämmt. Dabei kann das dritte Zahnrad achsparallel und/oder in radialer Richtung versetzt zu der Rotorwelle und/oder zu dem ersten Zahnrad und/oder zu dem zweiten Zahnrad angeordnet sein. Darüber hinaus kann das dritte Zahnrad einen anderen Teilbereich aufweisen, der versetzt zu dem Teilbereich angeordnet ist. Insbesondere kann der andere Teilbereich in axialer Richtung des dritten Zahnrads versetzt zu dem Teilbereich angeordnet sein. Der andere Teilbereich dient zum triebtechnischen Verbinden der Rotorwelle mit dem dritten Zahnrad. Darüber hinaus kann der andere Teilbereich einen anderen Durchmesser aufweisen als der Teilbereich.The hybrid transmission may have a third gear. The third gear may have a portion with a toothing, which meshes with a toothing of the second gear. In this case, the third gear can be arranged parallel to the axis and / or offset in the radial direction to the rotor shaft and / or to the first gear and / or to the second gear. In addition, the third gear may have a different portion which is arranged offset to the portion. In particular, the other portion may be arranged offset in the axial direction of the third gear to the portion. The other portion is used for driving technical connection of the rotor shaft with the third gear. In addition, the other portion may have a different diameter than the portion.
Der andere Teilbereich des dritten Zahnrads kann mit dem Zugmittel form- und/oder reibschlüssig verbunden sein. Bei einer Ausführung des Zugmittels als Kette kann der andere Teilbereich eine andere Verzahnung aufweisen, die mit der Kette formschlüssig verbunden ist. Im Ergebnis ist dasselbe dritte Zahnrad triebtechnisch sowohl mit dem zweiten Zahnrad als auch mit dem ersten Zahnrad verbunden.The other portion of the third gear may be positively and / or frictionally connected to the traction means. In one embodiment of the traction means as a chain, the other portion may have a different toothing, which is positively connected to the chain. As a result, the same third gear is drivingly connected to both the second gear and the first gear.
Die Rotorwelle und die Getriebeeingangswelle können achsparallel zueinander angeordnet und/oder in radialer Richtung zueinander versetzt angeordnet sein. Darüber hinaus können die Rotorwelle und die Getriebeeingangswelle miteinander stets triebtechnisch verbunden sein. The rotor shaft and the transmission input shaft can be arranged axially parallel to each other and / or arranged offset to one another in the radial direction. In addition, the rotor shaft and the transmission input shaft can always be connected to each other in terms of drive technology.
Im Ergebnis kann beim erfindungsgemäßen Hybridgetriebe eine bauraumoptimierte triebtechnische Verbindung zwischen der Rotorwelle und der Getriebeeingangswelle realisiert werden. Darüber hinaus kann das Hybridgetriebe auf einfache Weise montiert werden. Ein weiterer Vorteil besteht darin, dass durch das Vorsehen der verschiedenen Zahnräder und/oder des Zugmittels eine Übersetzung von der elektrische Maschine auf die Getriebeeingangswelle auf einfache Weise an die benötigte Übersetzung angepasst werden kann.As a result, a space-optimized drive connection between the rotor shaft and the transmission input shaft can be realized in the hybrid transmission according to the invention. In addition, the hybrid transmission can be mounted easily. Another advantage is that a translation of the electric machine to the transmission input shaft can be easily adapted to the required translation by providing the various gears and / or the traction means.
Von besonderem Vorteil ist ein Kraftfahrzeug mit der Kraftfahrzeugantriebseinrichtung und einem erfindungsgemäßen Hybridgetriebe. Die Kraftfahrzeugantriebseinrichtung kann ein Verbrennungsmotor oder eine weitere elektrische Maschine sein. Dabei kann die Antriebswelle der Kraftfahrzeugantriebseinrichtung mittels einer Anfahreinrichtung mit der Getriebeeingangswelle drehfest verbindbar sein. Die Anfahreinrichtung kann als Kupplung ausgeführt sein. Bei einer geschlossenen Kupplung ist die Antriebswelle mit der Getriebeeingangswelle drehfest verbunden.Of particular advantage is a motor vehicle with the motor vehicle drive device and a hybrid transmission according to the invention. The vehicle drive device may be an internal combustion engine or another electric machine. In this case, the drive shaft of the motor vehicle drive device can be connected in a rotationally fixed manner to the transmission input shaft by means of a starting device. The starting device can be designed as a clutch. In a closed clutch, the drive shaft is rotatably connected to the transmission input shaft.
Bei einer besonderen Ausführung kann das Getriebe eine Ölpumpe aufweisen, die eine Pumpenwelle umfasst. Die Ölpumpe dient zum Fördern von Öl innerhalb des Getriebes und stellt somit sicher, dass Getriebebauteilen Öl zum Kühlen und/oder Schmieren zugeführt werden kann. Die Pumpenwelle kann mittels der Anfahreinrichtung mit der Antriebswelle drehfest verbunden sein. Insbesondere kann die Pumpenwelle stets drehfest mit einem Bestandteil der Anfahreinrichtung verbunden sein. Der Bestandteil der Anfahreinrichtung kann zusätzlich mit der Antriebswelle stets drehfest verbunden sein. Dies bedeutet, dass die Ölpumpe permanent durch die Kraftfahrzeugantriebseinrichtung angetrieben wird.In a particular embodiment, the transmission may include an oil pump that includes a pump shaft. The oil pump serves to convey oil within the gearbox and thus ensures that gear components oil can be supplied for cooling and / or lubrication. The pump shaft can be rotatably connected by means of the starting device with the drive shaft. In particular, the pump shaft can always be rotatably connected to a component of the starting device. The component of the starting device can be connected in addition to the drive shaft always rotatably. This means that the oil pump is permanently driven by the motor vehicle drive device.
Das Getriebe kann ein Automatgetriebe und/oder ein Front-Quergetriebe sein. Dabei kann das Getriebe zum Schalten von wenigstens neun, insbesondere genau neun, Gängen dienen. Die einzelnen Gänge weisen eine unterschiedliche Übersetzung zwischen der Getriebeeingangswelle und einer Getriebeausgangswelle auf. Zum Realisieren von mehreren Gängen mit jeweils unterschiedlichen Übersetzungen kann das Getriebe mehrere Schaltelemente und/oder Radsatzelemente aufweisen. Dabei kann zum Realisieren eines Ganges ein einziges Schaltelement oder mehrere Schaltelemente geschlossen werden. Die Getriebeeingangswelle kann mit wenigstens einem Radsatzelement triebtechnisch verbunden sein. Das Getriebe kann eine Getriebeausgangswelle aufweisen, die triebtechnisch mit einem Achsdifferential verbunden ist.The transmission may be an automatic transmission and / or a front-transverse transmission. The transmission can serve for switching at least nine, in particular exactly nine, gears. The individual gears have a different ratio between the transmission input shaft and a transmission output shaft. To realize multiple gears, each with different ratios, the transmission may have a plurality of shift elements and / or wheelset elements. In this case, to realize a gear, a single switching element or a plurality of switching elements can be closed. The transmission input shaft may be connected to at least one wheel set element in terms of drive technology. The transmission may have a transmission output shaft which is connected to an axle differential in terms of drive technology.
