Description
Die Erfindung betrifft eine Hybridantriebseinheit gemäß dem Oberbegriff des Anspruches 1.The The invention relates to a hybrid drive unit according to the preamble of claim 1.
Heutzutage ist der Drehmomentwandler die gängige Technologie als Anfahrelement in einem Lastschaltgetriebe. Bei einem Übergang zur Hybridtechnologie wäre eine Möglichkeit, eine Hybridantriebseinheit auf dem Platz des Wandlers vorzusehen, wobei es wünschenswert ist, dass die Hybridantriebseinheit den gleichen oder geringeren Bauraum als der Wandler in Anspruch nimmt.nowadays the torque converter is the most common Technology as a starting element in a power shift transmission. At a transition to hybrid technology would be a possibility, to provide a hybrid drive unit on the place of the converter, where it is desirable is that the hybrid drive unit the same or less Space as the converter takes.

Größere Veränderungen im Getriebe, wie beispielsweise eine neue Auslegung der Hydraulik- beziehungsweise eine Änderung der Kühlflüssigkeitsleitungen, sind mit hohem Aufwand und Kosten verbunden. Eine Anpassung der Hybridantriebseinheit zu den im Getriebe schon vorhandenen Hydraulik- bezie hungsweise Kühlflüssigkeitsleitungen würde eine Verbreitung der Hybridtechnologie begünstigen.Big changes in the transmission, such as a new interpretation of the hydraulic or a change the coolant lines, are associated with high costs and costs. An adaptation of the Hybrid drive unit to the existing hydraulic in the transmission or coolant lines would one Promote the spread of hybrid technology.
Es ist die Aufgabe der vorliegenden Erfindung, eine Hybridantriebseinheit vorzusehen, die mit vorhandenen Antriebssystemen, das heißt deren Getrieben und Verbrennungsmotoren zusammengebaut werden kann, ohne wesentliche Veränderungen insbesondere bezüglich des Kühlmittel-Kreislaufs derselben durchzuführen.It The object of the present invention is a hybrid drive unit provide that with existing drive systems, that is their Driven and internal combustion engines can be assembled without significant changes especially regarding of the coolant circuit to do the same.
Erfindungsgemäß wird diese Aufgabe durch eine Hybridantriebseinheit für ein Kraftfahrzeug gelöst, welche zwischen einem Verbrennungsmotor und einem Fahrzeuggetriebe eine elektrische Maschine aufweist, die mindestens einen Rotor und einen Stator enthält und die elektrische Maschine als Motor oder Generator betreibbar ist. Radial innerhalb der elektrischen Maschine ist mindestens eine hydraulisch schaltbare nasslaufende Kupplung angeordnet. Das Fahrzeuggetriebe, insbesondere ein Lastschaltgetriebe, weist eine Getriebeeingangswelle und ein Getriebegehäuse auf. Ein Kühlmittel, beispielsweise ein Kühlöl, wird erfindungsgemäß durch eine zentrale Kühlmittelversorgung des Getriebes zur Hybridantriebseinheit zu- und abgeführt. Die Kühlmittelversorgung geht in einen im Wesentlichen geschlossenen Kühlmittel-Kreislauf über. Das Kühlmittel wird insbesondere zur Kühlung der Kupplung genutzt, aber beispielsweise auch zur Schmierung der im Kühlmittel-Kreislauf angeordneten Lager und als Druckflüssigkeit in dem Druckausgleichraum. Durch Verwendung der bereits vorhandenen zentralen Kühlmittelversorgung des Getriebes kann die Hybridantriebseinheit in einen Antriebsstrang mit einem Verbrennungsmotor und einem Getriebe mit geringem Aufwand, beispielsweise im Tausch gegen einen hydrodynamischen Wandler, eingebaut werden. Platz wird gespart durch das Ausnutzen des Kupplungsbereichs im Kühlmittel-Kreislauf als Druckausgleichsraum für die Kupplung. Auf einen separaten Druckausgleichsraum kann verzichtet werden, da das Kühlmittel auf beiden Seiten des Kupplungskolbens vorgesehen ist und somit ein gleich hoher Rotationsdruck auf beiden Seiten des Kupplungskolbens aufgebaut wird. Eine Rückstellfeder des Kupplungskolbens kann eingespart werden, da der Druck im Kühlmittel-Kreislauf beispielsweise zwischen 4 und 6 bar eingestellt ist und der Kupplungskolben zurückgestellt wird, sobald der Steuerdruck des Kupplungskolbens unter den momentanen Druck im Kühlmittel-Kreislauf abfällt. Da ein Antriebsstrang mit wenigen Ergänzungen zu einem Hybridantriebsstrang erweitert werden kann, ist dies ein Vorteil, der es möglich macht, die Hybridtechnik zu angemessenen Kosten herzustellen. Ebenfalls wird der Einbau einer Hybridantriebseinheit in derzeitige Verbrennungsmotor-Fahrzeuge ohne größere bauliche Veränderungen vereinfacht und die Attraktivität der Hybrid-Technologie erhöht.According to the invention this Problem solved by a hybrid drive unit for a motor vehicle, which between an internal combustion engine and a vehicle transmission a having electrical machine, the at least one rotor and a Stator contains and the electric machine as a motor or generator operable is. Radial inside the electric machine is at least one arranged hydraulically switchable wet-running clutch. The vehicle transmission, in particular a power shift transmission, has a transmission input shaft and a transmission housing on. A coolant, For example, a cooling oil is according to the invention by a central coolant supply the transmission to the hybrid drive unit and discharged. The Coolant supply goes into a substantially closed coolant circuit. The coolant is used in particular for cooling used the clutch, but also for example for the lubrication of the Coolant circulation arranged bearings and as pressure fluid in the pressure compensation chamber. By using the already existing central coolant supply The transmission can be the hybrid drive unit in a drive train with an internal combustion engine and a transmission with little effort, for example, in exchange for a hydrodynamic converter installed become. Space is saved by taking advantage of the coupling area in the coolant circuit as a pressure compensation room for the coupling. On a separate pressure compensation room can be omitted be as the coolant is provided on both sides of the clutch piston and thus an equally high rotational pressure on both sides of the clutch piston built becomes. A return spring the clutch piston can be saved, since the pressure in the coolant circuit for example, is set between 4 and 6 bar and the clutch piston reset is, as soon as the control pressure of the clutch piston is below the current Pressure in the coolant circuit drops. As a powertrain with few additions to a hybrid powertrain can be extended, this is an advantage that makes it possible to produce the hybrid technology at a reasonable cost. Also the installation of a hybrid drive unit in current internal combustion engine vehicles without major structural changes Simplified and attractive the hybrid technology increases.
Die zentrale Kühlmittelversorgung ist begrenzt durch eine mit dem Getriebegehäuse drehfest verbundene Hohlachse und der innerhalb der Hohlachse befindlichen Getriebeeingangswelle, wobei der Kühlmittel-Kreislauf außerhalb der Hohlachse und innerhalb des Rotors der elektrische Maschine vorgesehen ist.The central coolant supply is limited by a rotatably connected to the transmission housing hollow shaft and the transmission input shaft located within the hollow axle, the coolant circuit outside the hollow shaft and provided within the rotor of the electric machine is.
Der Kühlmittel-Kreislauf ist mit Dichtungen versehen, beispielsweise können O-Ringe, Rechteckringe oder Radialwellendichtringe verwendet werden. Die Rechteckringe werden bei höheren Drücke bis 70 bar eingesetzt, weisen jedoch kleinere Leckagen auf. Die Radialwellendichtringe sind nur für niedrige Drücke geeignet. Dichtungen werden üblicherweise zwischen zwei relativ zueinander drehenden Bauteilen vorgesehen, wobei alle drehenden Dichtungen in dem Kühlmittel-Kreislauf erfindungsgemäß nahe zur Getriebeeingangswelle angeordnet sind, so dass die konstruktiv höchst zulässige Gleitgeschwindigkeit der Dichtungen, beispielsweise 30 m/s, nicht überschritten wird. Vorzugsweise sollten die Dichtringe innerhalb der ersten Hälfte des Innenradius des Rotors vorgesehen sein.The coolant circuit is provided with seals, for example, O-rings, rectangular rings or radial shaft seals can be used. The rectangular rings are used at higher pressures up to 70 bar, but have smaller leaks. The radial shaft seals are only suitable for low pressures. Seals are usually provided between two relatively rotating components, wherein all rotating seals in the coolant circuit according to the invention are arranged close to the transmission input shaft, so that the constructively highly permissible sliding speed of the seals, for example 30 m / s, is not exceeded. Preferably, the sealing rings should be provided within the first half of the inner radius of the rotor.
Die Dichtungen sind zwischen einem mit der Getriebeeingangswelle rotierenden und einem gehäusefesten Bauteil und/oder zwischen einem mit der Getriebeeingangswelle rotierenden und einem mit dem Rotor rotierenden Bauteil und/oder zwischen einem mit dem Rotor rotierenden und einem gehäusefesten Bauteil und/oder zwischen einem mit dem Rotor rotierenden und einem mit einer Pumpenantriebswelle rotierenden Bauteil vorgesehen.The Seals are between one rotating with the transmission input shaft and a housing-proof Component and / or between a rotating with the transmission input shaft and a component rotating with the rotor and / or between a rotor rotating with the rotor and a housing-fixed component and / or between one rotating with the rotor and one with a pump drive shaft provided rotating component.
Insbesondere können fünf Dichtungen benutzt werden, wobei die erste Dichtung zwischen dem Träger des Rotors und der Pumpenantriebswelle vorgesehen ist und die Pumpenantriebswelle auf der Hohlachse gelagert ist. Die zweite Dichtung ist zwischen dem Rotorträger und einem mit der Getriebeeingangswelle rotierenden Bauteil vorgesehen und die dritte Dichtung ist zwischen einem mit dem Rotorträger rotierenden Bauteil und einem mit der Getriebeeingangswelle rotierenden Bauteil vorgesehen. Die vierte Dichtung ist zwischen einem mit der Getriebeeingangswelle rotierenden Bauteil und dem verbrennungsmotorseitigen Ende der Hohlachse vorgesehen und die fünfte Dichtung ist zwischen einem gehäusefesten und einem mit dem Rotor der elektrischen Maschine rotierenden Bauteil vorgesehen. Wenn die Dichtungen in der vorbeschriebenen Weise angeordnet sind, können alle Dichtungen vorteilhafterweise nahe zur Getriebeeingangswelle platziert werden. Die ersten vier Dichtungen sind höheren Drücken ausgesetzt, dürfen jedoch kleinere Leckagen vorweisen, da diese sämtlich in einem Nassraum angeordnet sind und ausschließlich verschiedene Bereiche mit unterschiedlichen Drücken gegeneinander abdichten. Die fünfte Dichtung braucht nicht den hohen Drücken standhalten, muss jedoch den Nassraum gegen einen Trockenraum zuverlässig abdichten.Especially can five seals be used, wherein the first seal between the carrier of the Rotor and the pump drive shaft is provided and the pump drive shaft is mounted on the hollow axle. The second seal is between the rotor carrier and provided with a rotating with the transmission input shaft component and the third seal is between one rotating with the rotor carrier Component and a rotating with the transmission input shaft component intended. The fourth seal is between one with the transmission input shaft rotating component and the internal combustion engine end of the hollow shaft provided and the fifth Seal is between a housing fixed and a component rotating with the rotor of the electric machine intended. When the seals are arranged in the manner described above are, can all seals advantageously close to the transmission input shaft to be placed. The first four seals are exposed to higher pressures allowed to However, show minor leaks, since all arranged in a wet room are and exclusively seal different areas with different pressures against each other. The fifth Seal does not need to withstand the high pressures, but it has to reliably seal the wet room against a dry room.
Das Kühlmittel wird von der zentralen Kühlmittelversorgung durch mindestens eine zuführende Kühlmittelleitung in den Kühlmittel-Kreislauf zugeführt und durch angrenzende Bauteile, beispielsweise den Rotorträger, radial nach außen zur Innenseite des Rotors der elektrischen Maschine geführt. Von der Innenseite des Rotors wird das Kühlmittel durch die Kupplung, beziehungsweise durch den Druckausgleichraum, radial nach innen zurück zur Getriebeeingangswelle und zu der zentralen Kühlmittelversorgung geführt.The coolant is from the central coolant supply by at least one supplying coolant line in the coolant circuit supplied and by adjacent components, such as the rotor arm, radially outward led to the inside of the rotor of the electric machine. Of the Inside the rotor becomes the coolant through the coupling, or through the pressure compensation chamber, radially inward back led to the transmission input shaft and to the central coolant supply.
Innerhalb der Hohlachse ist eine Buchse vorhanden und innerhalb der Buchse befindet sich die Getriebeeingangswelle. Die Buchse trennt in der zentralen Kühlmittelversorgung die Zu- und Abflussleitungen für das Kühlmittel voneinander, wobei der Zufluss zwischen der Buchse und der Hohlachse und der Abfluss zwischen der Buchse und der Getriebeeingangswelle erfolgt. Zwischen den Zu- und Abflussleitungen der zentralen Kühlmittelversorgung wird das Kühlmittel durch den Kühlmittel-Kreislauf geführt und passiert die erste und die zweite und die dritte und die vierte Dichtung nach einander.Within the hollow axle is a socket and inside the socket is the transmission input shaft. The socket separates in the central Coolant supply the inflow and outflow pipes for the coolant from each other, the inflow between the bushing and the hollow axle and the drain between the sleeve and the transmission input shaft he follows. Between the inlet and outlet pipes of the central coolant supply is the coolant passed through the coolant circuit and happens the first and the second and the third and the fourth Seal after each other.
Durch die erfindungsgemäße Lage der Dichtungen und den Fluss des Kühlmittels können alle Dichtungen nahe zur Getriebewelle angeordnet und der Spalt zwischen Rotor und Stator in der elektrischen Maschine kann trocken ausgebildet werden. Mit einem trockenen Spalt zwischen Rotor und Stator werden vorteilhafterweise nur geringe Wirbelverluste entstehen. Dazu kann aufgrund des erfindungsgemäßen Kühlmittelverlaufs im Kupplungsbereich ein Druckausgleich erfolgen und der Bauraum für einen separaten Druckausgleichsraum wird eingespart und eine komprimierte Bauweise ermöglicht.By the situation according to the invention the seals and the flow of the coolant can close all seals close to Gear shaft arranged and the gap between the rotor and stator in the electric machine can be made dry. With a dry gap between rotor and stator are advantageously only slight swirl losses occur. This can be due to the coolant flow according to the invention in the coupling area a pressure equalization and the space for a separate one Pressure equalization space is saved and a compressed construction allows.
In dem Getriebegehäuse werden Öffnungen zur Durchführung von Kühlmittel-, Strom- und Signalanschlüssen für die elektrische Maschine vorgesehen, um das Getriebe an die Hybridantriebseinheit anzupassen.In the gearbox be openings to execution of coolant, Power and signal connections for the provided electrical machine to adapt the transmission to the hybrid drive unit.
In der Hybridantriebseinheit ist eine Kupplung vorgesehen. Wenn die Kupplung hydraulisch gesteuert ist, ist eine Druckleitung zur Zuführung eines Mediums zur Betätigung der Kupplung radial innerhalb der Hohlachse des Getriebes, insbesondere im Innenraum der Getriebeeingangswelle, vorgesehen.In the hybrid drive unit is provided a clutch. If the Coupling is hydraulically controlled, is a pressure line for feeding a Medium for operation the coupling radially within the hollow axis of the transmission, in particular in Interior of the transmission input shaft, provided.
