Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine Versorgung einer nasslaufenden, ein Pumpenantriebselement aufweisenden Kupplung eines Getriebes mit Hydraulikflüssigkeit und Kühl- und Schmierstoff gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to a supply of a wet-running, a pump drive element having clutch of a transmission with hydraulic fluid and coolant and lubricant according to the preamble of claim 1.
Die Hydraulikflüssigkeit zur Betätigung einer nasslaufenden Kupplung bzw. einer Doppelkupplung wird nach dem Stand der Technik von der Ölversorgung über eine aufwändige Kupplungsnabe mittels Drehübertragern an die Kupplung geleitet. Hierbei erfolgt die Lagerung der Kupplung axial betrachtet hinter dem Bereich der Ölübergabe, was den axialen Bauraumbedarf in nachteiliger Weise erhöht.The Hydraulic fluid for operating a wet-running Clutch or a double clutch is according to the prior art from the oil supply through a complex Coupling hub passed by means of rotary transducers to the coupling. Here, the bearing of the coupling takes place axially behind the area of oil transfer, what the axial space requirement disadvantageously increased.
Um den Schmier- und Kühlstoff zur Kupplung zu transportieren, wird es bei Doppelkupplungsgetrieben bei einer Ausführungsform vom Antrieb durch das ganze Getriebe durch die Vorgelegewelle zu der dem Antrieb gegenüberliegenden Seite geleitet und von dort aus durch die innere Antriebswelle wieder zum Antrieb geleitet. Dabei erfolgt die Übergabe von der Vorgelegeweile zur Antriebswelle mittels eines aufwändigen Drehübertragers.Around to transport the lubricant and coolant to the clutch, it is in dual-clutch transmissions in one embodiment from the drive through the entire transmission through the countershaft the opposite side of the drive and from There passed out through the inner drive shaft back to the drive. The transfer of the Vorgelegeweile to the drive shaft by means of an elaborate rotary transformer.
Aus
der
Aus dem Stand der Technik sind Getriebe bekannt, bei denen die zur Hydraulikversorgung der Komponenten erforderliche Pumpe als off axis Pumpe ausgebildet ist und über einen den Achsversatz ausgleichenden Stirntrieb angetrieben wird, der in der Regel als geradverzahnte Stirnradstufe mit einem kupplungsseitigen treibenden Rad (Pumpenantriebsrad) und einem angetriebenen Rad ausgebildet ist.Out In the prior art transmissions are known in which the hydraulic supply the components required pump designed as an off-axis pump is and over a misalignment balancing forehead drive is driven, which is usually a straight-toothed spur gear with a clutch-side driving wheel (pump drive wheel) and a driven wheel is formed.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Versorgung einer nasslaufenden, ein Pumpenantriebselement aufweisenden Kupplung eines Getriebes mit Hydraulikflüssigkeit und/oder Kühl- und Schmierstoff anzugeben, durch die die aufwändige Kupplungsnabe zum Leiten der Hydraulikflüssigkeit und das aufwändige Durchleiten des Kühl- und Schmierstoffs durch das ganze Getriebe vermieden werden kann. Des weiteren sollen die hydraulischen Verluste minimiert und eine axiale Verlängerung des Getriebes vermieden werden.Of the present invention is based on the object, a supply a wet-running, a pump drive element having coupling a transmission with hydraulic fluid and / or cooling and Specify lubricant through the complex clutch hub for guiding the hydraulic fluid and the elaborate Passing the coolant and lubricant through the whole Transmission can be avoided. Furthermore, the hydraulic losses minimized and avoided an axial extension of the transmission become.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Weitere Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.These The object is achieved by the features of claim 1. Further embodiments and Advantages are apparent from the dependent claims.
Demnach wird eine Versorgung einer nasslaufenden, ein Pumpenantriebselement aufweisenden Kupplung eines Getriebes mit Hydraulikflüssigkeit und/oder Kühl- und Schmierstoff vorgeschlagen, wobei die Kupplung um eine äußere als Hohlwelle ausgeführte Welle angeordnet ist, bei der die Leitungen für die Hydraulikflüssigkeit und die Übergaben der Hydraulikflüssigkeit an die Kupplung und/oder die Leitungen für Kühl- und Schmierstoff und die Übergaben für Kühl- und Schmierstoff an die Kupplung in die als Hohlwelle ausgeführte Welle integriert sind.Therefore becomes a supply of a wet-running, a pump drive element having clutch of a transmission with hydraulic fluid and / or coolant and lubricant proposed, wherein the Coupling around an outer designed as a hollow shaft Shaft is arranged, at which the lines for the hydraulic fluid and the transfers of hydraulic fluid the coupling and / or the pipes for cooling and lubricant and the transfers for cooling and lubricant to the clutch in the form of a hollow shaft Wave are integrated.
Das Pumpenantriebselement kann erfindungsgemäß beispielsweise als Zahnrad, Kettenrad, Zahnriemenrad, Keilriemenrad oder als Reibrolle ausgebildet sein.The Pump drive element according to the invention, for example designed as a gear, sprocket, toothed belt, V-belt or friction roller be.
Im Rahmen einer vorteilhaften Ausführungsform der Erfindung wird zudem vorgeschlagen, dass ein Lager der Kupplungslagerung radial betrachtet unterhalb des Pumpenantriebselements angeordnet ist, wodurch sich die Kupplung auf der als Hohlwelle ausgeführten Welle abstützt; dadurch kann im Bereich der Übergabe von Hydraulikflüssigkeit und/oder Kühl- und Schmierstoff axialer Bauraum eingespart werden.in the Frame of an advantageous embodiment of the invention is also proposed that a bearing of the clutch bearing radially considered disposed below the pump drive element, whereby the clutch on the executed as a hollow shaft Shaft supports; This can be in the area of transfer hydraulic fluid and / or coolant and lubricant axial space can be saved.
Durch die erfindungsgemäß vorgeschlagene Integration der Leitungen in die als Hohlwelle ausgeführte Welle sowie durch die Anordnung eines Lagers der Kupplungslagerung radial betrachtet unterhalb des Pumpenantriebselements wird die Kupplungsnabe in vorteilhafter Weise vereinfacht.By the integration proposed according to the invention the lines in the designed as a hollow shaft shaft and considered radially by the arrangement of a bearing of the clutch bearing below the pump drive element, the clutch hub is in an advantageous Simplified way.
Die erfindungsgemäße Versorgung einer nasslaufenden, ein Pumpenantriebselement aufweisenden Kupplung eines Getriebes mit Hydraulikflüssigkeit und/oder Kühl- und Schmierstoff kann bei jeder nasslaufenden Kupplung realisiert werden, beispielsweise auch bei einer Doppelkupplung, insbesondere eines Doppelkupplungsgetriebes, wobei in diesem Fall die als Hohlwelle ausgeführte Welle eine einer Kupplung der Doppelkupplung zugeordnete äußere Antriebswelle darstellt, durch die eine innere Antriebswelle geführt wird, welche der anderen Kupplung zugeordnet ist.The supply according to the invention of a wet-running, a pump drive element having clutch of a transmission with hydraulic fluid and / or coolant and lubricant can be realized in each wet-running clutch, for example, in a dual clutch, in particular a dual-clutch transmission, in which case the shaft designed as a hollow shaft one Represents coupling of the dual clutch associated outer drive shaft through which an inner Drive shaft is guided, which is associated with the other clutch.
Die Erfindung wird im folgenden anhand der beigefügten Figuren beispielhaft näher erläutert.The Invention will be described below with reference to the accompanying figures exemplified in more detail.
Es zeigen:It demonstrate:
Der allgemeine Aufbau und die Funktionsweise von nasslaufenden Kupplungen bzw. Doppelkupplungen sind dem Fachmann bestens bekannt, so dass im Folgenden die Bauteile beschrieben werden, die für die vorliegende Erfindung von Bedeutung sind.Of the General structure and functioning of wet-running clutches or double clutches are well known to those skilled in the art, so that Below, the components are described, which for the present invention are of importance.
