The first input shaft of the gearbox is connected to the internal combustion engine.

Das Zwei-Plus-Zwei-Getriebe der DE 10 2006 005 131 A1 sieht zur Zusammenschaltung einer Verbrennungskraftmaschine und eines Elektromotors zwei Planetengetriebe vor, welche derartig gestaltet, gestuft sind, so dass für den Elektromotor zwei weit gestufte Untersetzungen, für die Verbrennungskraftmaschine vier enger gestufte Untersetzungen zur Verfügung stehen. The two plus two gearbox of DE 10 2006 005 131 A1 provides for the interconnection of an internal combustion engine and an electric motor before two planetary gear, which are designed in such a way, are stepped, so that for the electric motor two far-stepped reductions, for the internal combustion engine four narrower reductions are available.

Der Antrieb der DE 10 2005 022 926 B3 sieht einen Elektromotor vor, der über ein Wechselgetriebe die Antriebsleistung bereitstellt. Motor und Wechselgetriebe sind in einem gemeinsamen Gehäuse angeordnet. The drive of the DE 10 2005 022 926 B3 provides an electric motor, which provides the drive power via a change gear. Motor and change gear are arranged in a common housing.

Die DE 10 2010 024 147 A1 beschreibt ein Zwei-Gang-Planetengetriebe mit einem Elektromotor, der in einem Hybridantrieb angeordnet sein kann. Das Sonnenrad ist drehfest mit einer Eingangswelle verbunden, der Planetenträger drehfest mit einer Ausgangswelle. Mit einer regelbaren Kupplung ist der Planetenträger entweder gegenüber der Eingangswelle oder gegenüber dem Hohlrad festlegbar. Über eine ausschließlich schaltbare Kupplung ist das Hohlrad gegenüber einem das Planetengetriebe stützenden Gehäuse festlegbar. The DE 10 2010 024 147 A1 describes a two-speed planetary gear with an electric motor, which may be arranged in a hybrid drive. The sun gear is rotatably connected to an input shaft, the planet carrier rotatably connected to an output shaft. With a controllable clutch, the planet carrier can be fixed either with respect to the input shaft or with respect to the ring gear. About an exclusively switchable coupling the ring gear relative to a planetary gear supporting the housing can be fixed.

Die Aufgabe der vorliegenden Erfindung besteht darin, einen Hybridantrieb in gegenüber den bekannten Lösungen verbesserter Ausführung vorzuschlagen. The object of the present invention is to propose a hybrid drive in relation to the known solutions of improved design.

Diese Aufgabe wird gelöst durch die Merkmale des Vorrichtungsanspruches. Weiterbildungen ergeben sich aus den Unteransprüchen. This object is achieved by the features of the device claim. Further developments emerge from the subclaims.

Die erfindungsgemäße Lösung besteht aus einem Hybridantrieb für ein Kraftfahrzeug, dessen Antriebsräder von einer Verbrennungskraftmaschine und/oder einem Elektromotor antreibbar sind, bestehend aus einem Elektromotor, der mit der Welle der Verbrennungskraftmaschine und insbesondere einer die Leistung für die Antriebsachse bereitstellende Antriebswelle eines der Verbrennungskraftmaschine nachgeschalteten Getriebes koppelbar ist, wobei der Elektromotor über eine schaltbare Getriebestufe auf die Antriebswelle wirkt und ein auf die schaltbare Getriebestufe einwirkendes Schaltmittel vorgesehen ist, durch welches der Elektromotor über eine durch die Getriebestufen realisierte Übersetzung mit der Antriebswelle kuppelbar als auch von der Antriebswelle abkuppelbar ist. Durch diese schaltbare Getriebestufe kann der Elektromotor länger in einem optimalen Motorenkennfeld betrieben werden. Weiterhin können durch die geringeren Rotordrehzahlen günstigere Bauteile für die Rotorlagerung verwendet werden. The solution according to the invention consists of a hybrid drive for a motor vehicle, whose drive wheels are drivable by an internal combustion engine and / or an electric motor, consisting of an electric motor connected to the shaft of the internal combustion engine and in particular a drive shaft of the internal combustion engine downstream of the drive shaft can be coupled, wherein the electric motor acts on the drive shaft via a switchable gear stage and acting on the switchable gear stage switching means is provided, through which the electric motor via a realized by the gear ratios with the drive shaft coupling and can be uncoupled from the drive shaft. Through this switchable gear stage, the electric motor can be operated longer in an optimal engine map. Furthermore, cheaper components for the rotor bearing can be used by the lower rotor speeds.

Die Erfindung weiterbildend sin die folgenden Maßnahmen vorgesehen:

  • – der Rotor des Elektromotors sitzt koaxial auf einer Hohlwelle, durch welche die Antriebswelle bzw. eine die Antriebswelle verlängernde Eingangswelle des Hybridantriebes hindurchgeführt ist. Durch diese koaxiale Anordnung des Elektromotors zu der Antriebswelle, der Kardanwelle ergibt sich ein kompakte Bauweise. Insbesondere ist so in einfacher Weise ein dem Getriebe nachgeordneter Hybridantrieb realisierbar.
  • – die schaltbare Getriebestufe ist als ein Planetengetriebe ausgebildet. Hierdurch ergibt sich ein geringes Baumaß in Achsrichtung.
  • – die Hohlwelle des Elektromotors ist mit einem Sonnenrad verbunden, welches mit Planetenrädern kämmt, die ihrerseits in der Innenverzahnung eines gehäusefesten Hohlrades laufen.
  • – das Schaltmittel ist als eine drehfest und axial verschiebbar auf der Eingangswelle gelagerte Schiebemuffe ausgebildet.
  • – die Schiebemuffe wird durch die Kraft einer axial abgestützten Druckfeder in einer ersten Kuppelstellung gehalten und über ein zugeordnetes Betätigungselement entgegen der Federkraft entweder in eine nicht kuppelnde Zwischenstellung oder in eine weitere Kuppelstellung gedrückt. Bevorzugt ist hierzu das Betätigungselement als ein Proportional-Elektromagnet ausgebildet.
  • – der Elektromotor wird über eine zugeordnete Steuerung vor Betätigen des Schaltmittels in einen momentfreien Zustand geschaltet, in welchem dieser synchron zu dem Getriebeelement läuft, in welches ein- bzw. ausgekuppelt wird.
  • – die Schiebemuffe kuppelt in einer ersten Stufe bzw. Kuppelstellung einen die Planetenräder tragenden Planetenträger mit der Eingangswelle, in einer zweiten Stufe bzw. Kuppelstellung das Sonnenrad der Hohlwelle direkt mit der Eingangswelle, wobei in einer Zwischenstellung die Hohlwelle und somit der Elektromotor von der Eingangswelle entkoppelt ist.
  • – der Hybridantrieb ist als eine in einem Gehäuse angeordnete Motor- und Getriebeeinheit ausgebildet, mit einer Eingangswelle, die einerseits mit der Ausgangswelle des Getriebes der Verbrennungskraftmaschine und andererseits mit einer die Antriebsleistung auf die Antriebsachse weiterleitenden Antriebswelle, der Kardanwelle verbindbar ist.
Further developing the invention, the following measures are provided:
  • - The rotor of the electric motor is seated coaxially on a hollow shaft through which the drive shaft or a drive shaft extending input shaft of the hybrid drive is passed. By this coaxial arrangement of the electric motor to the drive shaft, the propeller shaft results in a compact design. In particular, a subordinate to the transmission hybrid drive can be realized in a simple manner.
  • - The switchable gear stage is designed as a planetary gear. This results in a low structural dimension in the axial direction.
  • - The hollow shaft of the electric motor is connected to a sun gear, which meshes with planet wheels, which in turn run in the internal toothing of a housing-fixed ring gear.
  • - The switching means is designed as a rotatably and axially displaceably mounted on the input shaft sliding sleeve.
  • - The sliding sleeve is held by the force of an axially supported compression spring in a first coupling position and pressed against an associated actuating element against the spring force either in a non-coupling intermediate position or in another coupling position. For this purpose, the actuating element is preferably designed as a proportional solenoid.
  • - The electric motor is switched via an associated control before operating the switching means in a torque-free state in which this runs synchronously to the transmission element, in which on or disengaged.
  • - The sliding sleeve couples in a first stage or dome position a planet carrier bearing the planetary gear with the input shaft, in a second stage or dome position the sun gear of the hollow shaft directly to the input shaft, wherein decoupled in an intermediate position, the hollow shaft and thus the electric motor of the input shaft is.
  • - The hybrid drive is as a arranged in a housing engine and transmission unit formed, with an input shaft which is connectable on the one hand to the output shaft of the transmission of the internal combustion engine and on the other hand with a drive power to the drive axle forwarding drive shaft, the propeller shaft.

Die Eingangswelle EW weist eine Schiebeverzahnung auf, in welcher eine Schiebemuffe SM axial beweglich eingreift und so drehfest mit der Eingangswelle EW verbunden ist. Die Schiebemuffe SM weist an ihrer zum Sonnenrad SR gewandten Ende eine Struktur in Form einer Verzahnung, Klauen auf, welche wahlweise in Eingriff mit einer korrespondierend dazu ausgebildeten Struktur an der Hohlwelle HW bzw. dem Sonnenrad SR oder in eine Struktur des Planetenträgers PT gebracht werden kann. Das Kuppeln erfolgt durch axiales Verschieben der Schiebemuffe SM. Sie Schiebemuffe SM wird über eine Druckfeder DF in Richtung Sonnenrad SR gedrückt, ein nicht dargestellter Elektromagnet, welcher als Proportionalmagnet ausgebildet ist, vermag die Schiebemuffe SM entgegen der Kraft der Druckfeder DF zu bewegen. The input shaft EW has a sliding toothing, in which a sliding sleeve SM axially movable engages and is rotatably connected to the input shaft EW. The sliding sleeve SM has at its end facing the sun gear SR a structure in the form of a toothing, claws, which can be selectively brought into engagement with a corresponding structure formed on the hollow shaft HW or the sun gear SR or in a structure of the planet carrier PT , The coupling takes place by axial displacement of the sliding sleeve SM. Sliding sleeve SM is pressed by a compression spring DF in the direction of the sun gear SR, an unillustrated solenoid, which is designed as a proportional magnet, is able to move the sliding sleeve SM against the force of the compression spring DF.

2a zeigt die Schiebemuffe SM in einer Position, in welcher der Planetenträger PT mit der Eingangswelle EW gekoppelt ist. Der Elektromotor EM speist nun sein Moment über das Sonnenrad SR und über den von den Planetenrädern PR getriebenen Planetenträger PT auf die Eingangswelle EW. Der Elektromotor EM treibt so in einer ersten Gangstufe. 2a shows the sliding sleeve SM in a position in which the planet carrier PT is coupled to the input shaft EW. The electric motor EM now feeds its torque via the sun gear SR and via the planet carrier PT driven by the planetary gears PR to the input shaft EW. The electric motor EM drives so in a first gear.

2c beschreibt eine Position, eine Kuppelstellung der Schiebemuffe SM, in welcher die Schiebemuffe SM vom Planetenträger PT ausgekuppelt ist und diese mit dem Sonnenrad SR der Hohlwelle HW gekuppelt ist. Der Elektromotor EM treibt nun in einer zweiten Gangstufe, und zwar direkt von der Hohlwelle HW auf die Eingangswelle EW. 2c describes a position, a coupling position of the sliding sleeve SM, in which the sliding sleeve SM is disengaged from the planet carrier PT and this is coupled to the sun gear SR of the hollow shaft HW. The electric motor EM now drives in a second gear stage, directly from the hollow shaft HW to the input shaft EW.

Zum Umschalten zwischen der ersten und der zweiten Gangstufe, den entsprechend realisierten Untersetzungen, wird zunächst der Elektromotor EM über eine ihm zugeordnete Steuerung in einen lastfreien Zustand geregelt, in dem dieser momentfrei läuft. Die beschriebenen Kupplungsstrukturen von Schiebemuffe SM, Sonnenrad SR sowie dem Planetenträger PT sind derartig gestaltet, dass Flankenspiel vorliegt und dadurch die Schiebemuffe SM durch entsprechendes Bestromen des Elektromagneten in eine Zwischenstellung verbracht werden kann, in welcher diese weder in Eingriff mit dem Sonnenrad SR noch mit dem Planetenträger PT steht. Diese Zwischenstellung der Schiebemuffe SM ist in der 2b wiedergegeben. To switch between the first and second gear, the correspondingly realized reduction ratios, the electric motor EM is initially controlled via a control associated with it in a no-load state in which this runs torque-free. The described coupling structures of sliding sleeve SM, sun gear SR and the planet carrier PT are designed such that backlash exists and thereby the sliding sleeve SM can be moved by appropriate energizing the electromagnet in an intermediate position in which this neither in engagement with the sun gear SR still with the Planet carrier PT stands. This intermediate position of the sliding sleeve SM is in the 2 B played.

Vor dem jeweiligen Umschalten der Schiebemuffe SM und somit der Einspeisung des Elektromotors EM in den Antriebsstrang wird der Elektromotor EM momentenfrei geschaltet, so dass dieser ohne einspeisendes Drehmoment synchron zur Eingangswelle EW bzw. zum Planetenträger PT läuft. In der Zwischenstellung, also nach dem Auskuppeln erfolgt ein Synchronisieren, d.h. der Elektromotor wird auf die Drehzahl des nun zu kuppelnden Getriebeteils hoch- bzw. herunterbeschleunigt. Before the respective switching of the sliding sleeve SM and thus the feeding of the electric motor EM in the drive train of the electric motor EM is switched torque free, so that it runs without feeding torque synchronous to the input shaft EW and the planet carrier PT. In the intermediate position, ie after disengaging, synchronization, i. the electric motor is accelerated up or down to the speed of the now to be coupled gear part.

Die 3–5 zeigen die Anordnung des erfindungsgemäßen Hybridantriebs HA mit dem Elektromotor EM im Detail. Die Eingangswelle EW ist auf der einen Seite mit dem nicht dargestellten Getriebeausgang des Schaltgetriebes SG verbunden. Die andere Seite der Eingangswelle EW trägt einen Antriebsflansch AF, über welchen die Verbindung mit der nicht dargestellten Antriebswelle zu der Antriebsachse AA erfolgt. Der Elektromotor EM besteht aus einem Rotor R auf einer Hohlwelle HW, welche drehbar gelagert auf der Eingangswelle EW sitzt. Der Rotor R wirkt mit einem Stator S zusammen, der in einem die beschriebenen Teile des Motors sowie des Getriebes aufnehmenden Gehäuse GH sitzt. The 3 - 5 show the arrangement of the hybrid drive HA according to the invention with the electric motor EM in detail. The input shaft EW is connected on one side with the transmission output of the gearbox SG, not shown. The other side of the input shaft EW carries a drive flange AF, via which the connection with the drive shaft, not shown, to the drive axis AA. The electric motor EM consists of a rotor R on a hollow shaft HW, which rotatably mounted on the input shaft EW sits. The rotor R cooperates with a stator S which sits in a housing GH receiving the described parts of the engine and the transmission.

An einem Ende der Hohlwelle HW ist ein Sonnenrad SR angebracht, welches mit Planetenrädern PR kämmt, welche ihrerseits mit einem Planetenträger PT gekoppelt sind. Die Planetenräder PR laufen in einer Innenverzahnung eines Hohlrades HR, welches fest innerhalb des Gehäuses GH sitzt. At one end of the hollow shaft HW a sun gear SR is mounted, which meshes with planet gears PR, which in turn are coupled to a planet carrier PT. The planet gears PR run in an internal toothing of a ring gear HR, which sits firmly within the housing GH.

Auf der dem Rotor R abgewandten Seite des Sonnenrades SR ist drehfest und axial beweglich eine Schiebemuffe SM auf der Eingangswelle EW gelagert. Diese Schiebemuffe SM wird durch die Kraft einer sich achsfest abstützenden Druckfeder DF in Richtung Sonnenrad SR gedrückt. Die Schiebemuffe SM weist eine Kupplungsstruktur auf, welche mit korrespondierend dazu geformten Strukturen am Sonnenrad SR bzw. dem Planetenträger PT zusammenwirkt. Eine axiale Bewegung der Schiebemuffe SM bewirkt somit ein Kuppeln, drehfestes Verbinden des Planetenträgers PT mit der Eingangswelle EW, wobei diese Situation in der 3 wiedergegeben ist. Die Hohlwelle HW bzw. das vom Elektromotor getriebene Sonnenrad treibt nun über die Planetenräder PR die Eingangswelle. Diese Gangstufe entspricht dem Prinzipschaltbild 2a. On the rotor R side facing away from the sun gear SR is rotatably and axially movable a sliding sleeve SM mounted on the input shaft EW. This sliding sleeve SM is pressed in the direction of the sun gear SR by the force of a pressure spring DF which is supported axially in the axial direction. The sliding sleeve SM has a coupling structure, which cooperates with correspondingly shaped structures on the sun gear SR and the planet carrier PT. An axial movement of the sliding sleeve SM thus causes a coupling, rotationally fixed connection of the planet carrier PT to the input shaft EW, this situation in the 3 is reproduced. The hollow shaft HW or the sun gear driven by the electric motor now drives the input shaft via the planetary gears PR. This gear stage corresponds to the schematic diagram 2a ,

Das Verkuppeln der Eingangswelle EW mit dem Sonnenrad SR, d.h. der direkte Antrieb der Eingangswelle EW über den Rotor R ist in der 5 wiedergegeben. Diese Gangstufe entspricht dem Prinzipschaltbild nach 2c. Wird die Schiebemuffe durch entsprechndes Bestromen des Elektromagneten in eine mittlere Stellung verbracht, so ist weder das Sonnenrad SR noch der Planetenträger PT mit der Schiebemuffe gekoppelt. Dies entspricht dem Prinzipschaltbild 2b. The coupling of the input shaft EW with the sun gear SR, ie the direct drive of the input shaft EW via the rotor R is in the 5 played. This gear stage corresponds to the block diagram according to 2c , If the sliding sleeve spent by entsprechndes energizing the electromagnet in a middle position, so neither the sun gear SR nor the planet carrier PT is coupled to the sliding sleeve. This corresponds to the schematic diagram 2 B ,

Es sei darauf hingewiesen, die die 2a–2c ein Prinzipschaltbild darstellen, also lediglich den durch die Schiebemuffe SM bewirkbaren Momentenfluss des Elektromotors EM auf die Eingangswelle EW wiedergeben. Die tatsächliche Position der Schiebemuffe SM in der ersten und der zweiten Gangstufe ist in den 3 und 5 wiedergegeben und entspricht nicht den Positionen der Schiebemuffe SM in 2a bzw. 2c. It should be noted that the 2a - 2c represent a schematic diagram, so only play the effected by the sliding sleeve SM torque flow of the electric motor EM on the input shaft EW. The actual position of the sliding sleeve SM in the first and second gear stages is in the 3 and 5 reproduced and does not correspond to the positions of the sliding sleeve SM in 2a respectively. 2c ,
