Description
Die Erfindung betrifft eine Hybridantriebsvorrichtung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a hybrid drive device according to the preamble of patent claim 1.
Aus der gattungsgemäßen
Aufgabe der vorliegenden Erfindung ist es, eine Hybridantriebsvorrichtung mit möglichst guten Eigenschaften hinsichtlich Wirkungsgrad und Übersetzungsabstufung bei möglichst geringem benötigtem Bauraum darzustellen.The object of the present invention is to present a hybrid drive device with the best possible properties with regard to efficiency and gear ratio gradation with the smallest possible installation space required.
Diese Aufgabe wird erfindungsgemäß durch eine Hybridantriebsvorrichtung mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausführungen und Weiterbildungen der Erfindung sind den Unteransprüchen sowie der nachfolgenden Figurenbeschreibung zu entnehmen.This object is achieved by a hybrid drive device with the features of claim 1. Advantageous embodiments and developments of the invention can be found in the subclaims and the following description of the figures.
Es wird ausgegangen von einer Hybridantriebsvorrichtung, die einen Verbrennungsmotor, eine elektrische Maschine, einen Planetenradsatz, besonders vorteilhaft nämlich genau einen Planetensatz, und ein Stirnradgetriebe, welches ein erstes Teilgetriebe mit einer ersten Radebene und ein zweites Teilgetriebe mit einer zweiten Radebene aufweist, umfasst. Der Verbrennungsmotor weist dabei eine Kurbelwelle auf, die elektrische Maschine weist einen Stator und einen Rotor auf, und der Planetenradsatz weist eine Summenwelle, eine erste Differenzwelle, eine zweite Differenzwelle sowie ein Verblockungsschaltelement auf.
Dabei ist die Kurbelwelle über eine Kupplung mit der Summenwelle koppelbar, und der Rotor ist drehmomentübertragend an den Planetenradsatz gekoppelt. Ferner ist dabei das erste Teilgetriebe mittels eines ersten Teilgetriebeschaltelementes mit der ersten Differenzwelle koppelbar, und das zweite Teilgetriebe ist mittels eines zweiten Teilgetriebeschaltelementes mit der zweiten Differenzwelle koppelbar.The starting point is a hybrid drive device which comprises an internal combustion engine, an electric machine, a planetary gear set, particularly advantageously precisely one planetary gear set, and a spur gear transmission which has a first partial transmission with a first wheel plane and a second partial transmission with a second wheel plane. The internal combustion engine has a crankshaft, the electric machine has a stator and a rotor, and the planetary gear set has a sum shaft, a first differential shaft, a second differential shaft and an interlocking switching element.
The crankshaft can be coupled to the total shaft via a clutch, and the rotor is coupled to the planetary gear set in a torque-transmitting manner. Furthermore, the first partial transmission can be coupled to the first differential shaft by means of a first partial transmission shifting element, and the second partial transmission can be coupled to the second differential shaft by means of a second partial transmission shifting element.
Erfindungsgemäß sind das erste Teilgetriebeschaltelement und das zweite Teilgetriebeschaltelement in einer axialen Richtung gesehen zwischen dem Planetenradsatz und den Radebenen des Stirnradgetriebes angeordnet, wobei das erste Teilgetriebeschaltelement dazu ausgebildet ist, die erste Differenzwelle drehfest mit einer als Vollwelle ausgebildeten ersten Eingangswelle des ersten Teilgetriebes zu verbinden. Auf diese Weise lässt sich eine besonders kompakte und kostengünstige und zugleich performante Gesamtstruktur darstellen.According to the invention, the first partial transmission switching element and the second partial transmission switching element, viewed in an axial direction, are arranged between the planetary gear set and the gear planes of the spur gear, the first partial transmission switching element being designed to connect the first differential shaft in a rotationally fixed manner to a first input shaft of the first partial transmission designed as a solid shaft. In this way, a particularly compact and inexpensive, yet high-performance overall structure can be represented.
Mit einer drehfesten Verbindung zweier drehbar gelagerter Elemente ist gemeint, dass die beiden Elemente koaxial zueinander angeordnet sind und derart miteinander verbunden sind, dass sie mit gleicher Winkelgeschwindigkeit drehen. Mit einer drehfesten Verbindung eines Elementes mit einem Gehäuse ist gemeint, dass das Element derart mit dem Gehäuse verbunden ist, dass es nicht relativ zu dem Gehäuse verdreht werden kann.A rotationally fixed connection of two rotatably mounted elements means that the two elements are arranged coaxially to one another and are connected to one another in such a way that they rotate at the same angular velocity. A rotationally fixed connection of an element to a housing means that the element is connected to the housing in such a way that it cannot be rotated relative to the housing.
Mit der axialen Richtung ist die Richtung einer Drehachse der Kurbelwelle gemeint, wobei vorteilhaft die Kurbelwelle koaxial zu einer gemeinsamen Drehachse der Summenwelle und der Differenzwellen des Planetengetriebes angeordnet ist.The axial direction means the direction of an axis of rotation of the crankshaft, the crankshaft advantageously being arranged coaxially with a common axis of rotation of the sum shaft and the differential shafts of the planetary gear.
Mit den Radebenen des Stirnradgetriebes sind Ebenen gemeint, die senkrecht zu der axialen Richtung angeordnet sind und die durch Stirnradpaarungen des Stirnradgetriebes aufgespannt sind. Mit Stirnradpaarungen sind dabei Paare von Stirnrädern gemeint, die miteinander kämmen und die zur Bildung von schaltbaren Gängen des Stirnradgetriebes vorgesehen sind..The wheel planes of the spur gear transmission mean planes that are arranged perpendicular to the axial direction and that are spanned by spur gear pairs of the spur gear transmission. With spur gear pairs are meant pairs of spur gears that mesh with each other and that are provided to form switchable gears of the spur gear.
Vorteilhaft ist der Planetenradsatz als Einfachplanetenradsatz ausgebildet, wobei bei einem Einfachplanetenradsatz eine Planetenträgerwelle bekanntermaßen die Summenwelle bildet. Vorteilhaft ist die erste Differenzwelle als eine Sonnenwelle des Planetenradsatzes und die zweite Differenzwelle als eine Hohlradwelle des Planetenradsatzes ausgebildet. Vorteilhaft ist der Planetenradsatz als Einfachplanetenradsatz ausgeführt.The planetary gear set is advantageously designed as a simple planetary gear set, a planet carrier shaft, as is known, forming the sum shaft in a single planetary gear set. The first differential shaft is advantageously designed as a sun shaft of the planetary gear set and the second differential shaft as a ring gear shaft of the planetary gear set. The planetary gear set is advantageously designed as a simple planetary gear set.
Eine Weiterbildung der Erfindung sieht vor, dass genau die eine elektrische Maschine vorgesehen ist und dass das Verblockungsschaltelement und das zweite Schaltelement jeweils als Reibschaltelemente ausgeführt sind. Es hat sich herausgestellt, dass bei dem erfindungsgemäßen Gesamtkonzept ein optimaler Kompromiss zwischen Schaltbarkeit und Schaltkomfort der Hybridantriebsvorrichtung auf der einen Seite sowie Bauraum und Kosten auf der anderen Seite erzielt werden kann, wenn genau das Verblockungsschaltelement und genau eines der beiden Teilgetriebeschaltelemente als Reibschaltelemente ausgeführt sind.A further development of the invention provides that exactly one electrical machine is provided and that the interlocking switching element and the second switching element are each designed as friction switching elements. It has been found that with the overall concept according to the invention, an optimal compromise between shiftability and shifting comfort of the hybrid drive device on the one hand and installation space and costs on the other hand can be achieved if exactly the blocking shift element and exactly one of the two partial transmission shift elements are designed as friction shift elements.
Mit einem Reibschaltelement ist ein reibschlüssiges Schaltelement wie zum Beispiel eine Lamellenkupplung gemeint. A friction shift element means a frictional shift element such as a multi-plate clutch.
Eine weitere Weiterbildung der Erfindung sieht vor, dass das zweite Teilgetriebeschaltelement dazu ausgebildet ist, die zweite Differenzwelle drehfest mit einer als Hohlwelle ausgebildeten zweiten Eingangswelle des zweiten Teilgetriebes zu verbinden, wobei die zweite Eingangswelle koaxial zu der ersten Eingangswelle angeordnet ist. Besonders vorteilhaft ist die zweite Eingangswelle umgebend zu der ersten Eingangswelle angeordnet. Gegenüber dem Stand der Technik lässt sich dadurch eine die Kompaktheit der Hybridantriebsvorrichtung erhöhen.A further development of the invention provides that the second partial transmission shifting element is designed to connect the second differential shaft in a rotationally fixed manner to a second input shaft of the second partial transmission designed as a hollow shaft, the second input shaft being arranged coaxially with the first input shaft. The second input shaft is particularly advantageously arranged to surround the first input shaft. Compared to the prior art, the compactness of the hybrid drive device can thereby be increased.
Eine weitere Weiterbildung der Erfindung sieht vor, dass das Stirnradgetriebe eine erste Vorgelegewelle und eine zweite Vorgelegewelle aufweist, wodurch sich eine Kompaktheit, insbesondere in der axialen Richtung, erhöht werden kann. Vorteilhaft sind Stirnradschaltelemente zur Schaltung der Gänge des Stirnradgetriebes ausschließlich koaxial zu der ersten Vorgelegewelle oder koaxial zu der zweiten Vorgelegewelle angeordnet. Vorteilhaft enthalten somit die Stirnradpaarungen des Stirnradgetriebes jeweils ein auf einer der Eingangswellen, nämlich der ersten Eingangswelle oder der zweiten Eingangswellen, angeordnetes Festrad und ein auf einer der Vorgelegewellen, nämlich der ersten Vorgelegewelle oder der zweiten Vorgelegewelle, angeordnetes Losrad. Dabei sind die Stirnradschaltelemente koaxial zu den jeweils zugehörigen Losrädern angeordnet. Die Stirnradschaltelemente können dabei als Klauenschaltelemente mit Synchronisiereinrichtung oder als Klauenschaltelemente ohne Synchronisiereinrichtung ausgeführt sein.A further development of the invention provides that the spur gear has a first countershaft and a second countershaft, whereby a compactness, in particular in the axial direction, can be increased. Spur gear shifting elements for shifting the gears of the spur gear are advantageously arranged exclusively coaxially to the first countershaft or coaxially to the second countershaft. The spur gear pairings of the spur gear transmission thus advantageously each contain a fixed gear arranged on one of the input shafts, namely the first input shaft or the second input shafts, and an idler gear arranged on one of the countershafts, namely the first countershaft or the second countershaft. The spur gear shift elements are arranged coaxially with the associated idler gears. The spur gear switching elements can be designed as claw switching elements with a synchronizing device or as claw switching elements without a synchronizing device.
Eine weitere Weiterbildung der Erfindung sieht eine Abtriebsradebene vor, welche axial zwischen dem Verbrennungsmotor und dem Stirnradgetriebe angeordnet ist. Besonders vorteihaft sind der Verbrennungsmotor, der Planetenradsatz, das erste und die beiden Teilgetriebeschaltelemente die Abtriebsradebene und die Radebenen des Stirnradgetriebes in der genannten Reihenfolge in der axialen Richtung nacheinander angeordnet. Insgesamt lässt sich so eine besonders kompakte und kostengünstig herstellbare Hybridantriebsvorrichtung darstellen.A further development of the invention provides an output gear plane which is arranged axially between the internal combustion engine and the spur gear. Particularly advantageous are the internal combustion engine, the planetary gear set, the first and the two sub-gear shift elements, the driven gear plane and the gear planes of the spur gear in the order mentioned in the axial direction one after the other. Overall, a particularly compact and inexpensive to produce hybrid drive device can be represented.
Weitere vorteilhafte Weiterbildungen sind in den abhängigen Ansprüchen dargelegt bzw. ergeben sich aus der Zeichnung.Further advantageous developments are set out in the dependent claims or result from the drawing.
