Abstract
Description
Die vorliegende Erfindung betrifft ein Fahrzeug gemäß dem Oberbegriff des Patentanspruches 1.The The present invention relates to a vehicle according to the preamble of claim 1.
Automatikgetriebe vieler herkömmlicher Fahrzeuge werden aktiv gekühlt. Bei manchen Fahrzeugen ist an den Getriebeölkreislauf ein Getriebeöl-/Kühlmittelwärmetauscher angeschlossen, über den Wärme vom Getriebeöl auf das Kühlmittel des Kühlmittelkreislaufs des Fahrzeugs übertragen wird. Somit wird ein Großteil der im Getriebe anfallenden Wärmeleistung über den Getriebeöl-/Kühlmittelwärmetauscher, das Kühlmittel und den Fahrzeugkühler an die Umgebungsluft abgegeben. Bei derartigen Fahrzeugen ist der Getriebeöl-/Kühlmittelwärmetauscher üblicherweise direkt neben dem Kühlmodul vorderhalb des Fahrzeugsmotors angeordnet, d. h. relativ weit entfernt vom Getriebe.automatic transmission many conventional vehicles are actively cooled. In some vehicles, the transmission oil circuit is a transmission oil / coolant heat exchanger connected, over the Heat from transmission oil on the coolant of the coolant circuit of the vehicle becomes. Thus, a large part the heat output in the transmission over the Transmission oil / coolant heat exchanger, the coolant and the vehicle cooler the ambient air is released. In such vehicles, the transmission oil / coolant heat exchanger is common directly next to the cooling module in the front of the vehicle engine, d. H. relatively far away from Transmission.
Der Getriebeöl-/Kühlmittelwärmetauscher beansprucht relativ viel Bauraum, so dass für andere Komponenten im Bereich des Kühlmoduls entsprechend weniger Bauraum zur Verfügung steht. Außerdem ist die Verlegung der Leitungen, über die das Getriebe mit dem Getriebeöl-/Kühlmittelwärmetauscher verbunden ist, relativ aufwändig, da die Leitungsführung an diverse Fahrzeugvarianten (Dieselmotor, Ottomotor, Linkslenker, Rechtslenker, Standardantrieb, Allradantrieb etc.) angepasst werden muss. Darüber hinaus entstehen aufgrund der relativ großen Leitungslängen Druckverluste, was eine entsprechend große Pumpleistung erfordert.Of the Transmission oil / coolant heat exchanger claimed a relatively large amount of space, allowing for other components in the area of the cooling module correspondingly less Space available stands. Furthermore is the laying of the wires, over which the gearbox with the Transmission oil / coolant heat exchanger connected, relatively complex, because the wiring to various vehicle variants (diesel engine, gasoline engine, left-hand drive, Right-hand drive, standard drive, four-wheel drive, etc.) must be adjusted. About that In addition, pressure losses occur due to the relatively long line lengths. what a correspondingly large Pumping power required.
Aufgabe der Erfindung ist es, ein Fahrzeug zu schaffen, bei dem der Aufwand für die Kopplung des Getriebeölkreislaufs mit dem Kühlmittelkreislauf geringer ist als bei herkömmlichen Fahrzeugen.task The invention is to provide a vehicle in which the effort for the Coupling of the transmission oil circuit lower with the coolant circuit is as with conventional Vehicles.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.These The object is solved by the features of claim 1. advantageous Refinements and developments of the invention are the dependent claims remove.
Ausgangspunkt der Erfindung ist ein Fahrzeug mit einem in einem Getriebegehäuse untergebrachten Getriebe, insbesondere einem Automatikgetriebe, das durch einen Getriebeölkreislauf geschmiert und gekühlt wird. Das Fahrzeug weist ferner einen Kühlmittelkreislauf auf sowie einen Wärmetauscher, über den der Getriebeölkreislauf thermisch mit dem Kühlmittelkreislauf gekoppelt ist. Der Kern der Erfindung besteht darin, dass der Wärmetauscher am oder im Getriebegehäuse vorgesehen ist. „Im Getriebegehäuse" umfasst sowohl Ausführungsformen, bei dem der Wärmetauscher in das Getriebegehäuse an sich integriert ist, als auch Ausführungsformen, bei denen der Wärmetauscher im Bereich innerhalb des Getriebegehäuses, d. h. innerhalb des von der Innenseite des Getriebegehäuses definierten Raums angeordnet ist.starting point The invention is a vehicle with a housed in a transmission housing Transmission, in particular an automatic transmission, by a Transmission oil circuit lubricated and cooled becomes. The vehicle also has a coolant circuit and a heat exchanger, over the the transmission oil circuit thermally with the coolant circuit is coupled. The essence of the invention is that the heat exchanger on or in the gearbox is provided. "In the Gearbox "includes both embodiments, in that of the heat exchanger in the gearbox is integrated, as well as embodiments in which the heat exchangers in the area inside the gearbox, d. H. within the of the inside of the gearbox defined space is arranged.
Wie bereits angedeutet, muss der Getriebeöl-Kühlmittelwärmetauscher nicht notwendigerweise als separates Bauteil ausgestaltet sein. Er könnte auch in das Getriebegehäuse integriert sein, z. B. in Form eingegossener Fluidkanäle oder in Form von auf die Innenseite des Getriebegehäuses aufgebrachter Wellblechkomponenten o. ä. dargestellt sein. Durch eine Sandwich- bzw. Wabenstruktur oder durch die bereits erwähnte Integration des Getriebeöl-/Kühlmittelwärmetauschers in das Getriebegehäuse kann eine bedarfsorientierte Kühlung bzw. Aufheizung des Getriebes dargestellt werden. Außerdem ist mit denselben Komponenten eine Isolierung des Getriebes darstellbar und zwar sowohl in thermischer als auch in akustischer Hinsicht.As already indicated, the transmission oil-refrigerant heat exchanger does not necessarily have as be designed separate component. He could also be integrated in the gearbox be, z. B. in the form of cast-fluid channels or in the form of on the Inside of the gearbox be displayed corrugated iron components o. Ä. Be shown. By a Sandwich or honeycomb structure or by the already mentioned Integration of the transmission oil / coolant heat exchanger in the gearbox can be a demand-based cooling or heating of the transmission are shown. Besides that is with the same components an isolation of the transmission represented both in thermal and in acoustic terms.
Durch die getriebenahe Anordnung des Getriebeöl-/Kühlmittelwärmetauschers bzw. durch die Integration des Anordnung des Getriebeöl-/Kühlmittelwärmetauschers in das Getriebegehäuse wird im Motorraum zusätzlicher Bauraum frei, was hinsichtlich der Anordnung anderer Komponenten von Vorteil ist. Außerdem werden bei einer Anordnung des Getriebeöl-/Kühlmittelwärmetauschers im bzw. am Getriebe Kosten für die Leitungsführung eingespart. Zwischen dem Getriebe und dem Kühlmodul brauchen nämlich nicht mehr die relativ teuren Getriebeölleitungen verlegt werden, sondern es können kostengünstigere Kühlmittelleitungen verlegt werden. Dies ist insbesondere mit Blick auf Fahrzeuge von Vorteil, die sowohl als konventionelle Fahrzeuge auch als Hybridfahrzeuge angeboten werden, da bei Hybridfahrzeugen die im Getriebe angeordnete elektrische Maschine aktiv gekühlt werden muss und somit ohnehin an den Kühlmittelkreislauf angeschlossen werden muss.By the geared arrangement of the transmission oil / coolant heat exchanger or through the integration the arrangement of the transmission oil / coolant heat exchanger in the gearbox is added in the engine compartment Space free, what about the arrangement of other components is beneficial. Furthermore be in an arrangement of the transmission oil / coolant heat exchanger in or on the gearbox costs for the cable routing saved. That is not necessary between the transmission and the cooling module more the relatively expensive transmission oil lines but it can be relocated cost-effective Coolant lines be moved. This is particularly advantageous with regard to vehicles, both conventional vehicles as well as hybrid vehicles be offered because in hybrid vehicles arranged in the transmission Electric machine actively cooled must be and thus anyway connected to the coolant circuit must become.
Vorteilhaft bei einer Anordnung des Getriebeöl-/Kühlmittelwärmetauschers am oder im Getriebe ist ferner, dass das Getriebe während der Warmlaufphase des Fahrzeugs schneller auf Betriebstemperatur gebracht werden kann. Des Weiteren trägt ein am oder im Getriebe angeordneter Getriebeöl-/Kühlmittelwärmetauscher zur Dämpfung von im Getriebe erzeugten Geräuschen bei.Advantageous in an arrangement of the transmission oil / coolant heat exchanger On or in the gearbox is further that the transmission during the Warm-up phase of the vehicle brought faster to operating temperature can be. Furthermore, contributes on or in the transmission arranged transmission oil / coolant heat exchanger for damping of noise generated in the gearbox at.
Im Folgenden wird die Erfindung im Zusammenhang mit der Zeichnung näher erläutert. Es zeigen:in the The invention will be explained in more detail in connection with the drawing. It demonstrate:
