Description
Die Erfindung betrifft eine Vorrichtung zum Konditionieren von in einem Antriebsaggregat befindlichem Schmieröl gemäß dem Oberbegriff des Patentanspruches 1.The The invention relates to a device for conditioning in a Drive unit befindlichem lubricating oil according to the preamble of claim 1.
In Antriebsaggregaten von Kraftfahrzeugen, z. B. der Brennkraftmaschine und/oder des Geschwindigkeits-Wechselgetriebes ist es bekannt, aus Funktions und Wirtschaftlichkeitsgründen das Schmieröl (dies kann auch ein Hydrauliköl sein) zunächst aufzuheizen und bei Erreichen einer definierten Betriebstemperatur zu kühlen. Dazu eignet sich besonders das Kühlwasser der Brennkraftmaschine, das sich in der Regel schnell erwärmt (Aufheizphase) und später aufgrund seiner geringeren Betriebstemperatur als Kühlmittel einsetzbar ist. Diese Konditionierung des Schmieröles wird zumeist erreicht mittels eines externen oder eines in das Schmierölreservoir eingesetzten, internen Wärmetauschers. Nachteilig ist im Aufheizprozess die gesamte Ölmenge beteiligt. Das Schmieröl wird daher nur zeitverzögert erwärmt.In Drive units of motor vehicles, eg. B. the internal combustion engine and / or the speed change gear, it is known from function and economic reasons the lubricating oil (This can also be a hydraulic oil be) first to heat up and on reaching a defined operating temperature to cool. This is especially the cooling water the internal combustion engine, which usually heats up quickly (heating phase) and later due to its lower operating temperature than coolant can be used. This conditioning of the lubricating oil is mostly achieved by means of an external or one inserted into the lubricating oil reservoir, internal heat exchanger. The disadvantage is involved in the heating process, the total amount of oil. The lubricating oil is therefore only delayed heated.
Aufgabe der Erfindung ist es, eine Vorrichtung der gattungsgemäßen Art vorzuschlagen, die eine wirkungsvolle Konditionierung des Schmieröles oder eines Hydrauliköles sicherstellt.task The invention is a device of the generic type suggest that effective conditioning of the lubricating oil or a hydraulic oil ensures.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte und besonders zweckmäßige Weiterbildungen der Erfindung beinhalten die Unteransprüche.These Task is according to the invention with the Characteristics of claim 1 solved. Advantageous and special appropriate training of the invention include the subclaims.
Erfindungsgemäß wird vorgeschlagen, dass das Gehäuse des Ölsumpfes durch ein plattenförmiges oder wannenförmiges Trennelement in zwei Ölreservoire unterteilt ist, dass ferner das Schmieröl des einen Ölreservoirs umgewälzt wird und dass die beiden Ölreservoire über zumindest eine Öffnung miteinander verbindbar sind. Durch diese Maßnahme gelingt es, mit relativ einfachen Mitteln eine schnelle Erwärmung des Schmieröles zu erreichen, weil zum einen nur ein Anteil der gesamten Schmierölmenge umgewälzt wird und zum anderen die durch das Gehäuse gebildete Abkühlfläche zur Umgebung vermindert ist. Es versteht sich, dass sofern vorhanden die Ansaugstelle für das umzuwälzende Schmieröl in dem Ölreservoir liegen muss, in dem auch die die Öffnung temperaturabhängig steuernde Einsrichtung, z. B. ein Thermostat, positioniert ist.According to the invention, it is proposed that the case of the oil sump through a plate-shaped or trough-shaped Separating element in two oil reservoirs is divided, that further, the lubricating oil of an oil reservoir circulated and that the two oil reservoirs over at least an opening with each other are connectable. By this measure succeeds it, with relatively simple means a rapid warming of the lubricating oil to achieve because on the one hand only a portion of the total amount of lubricating oil is circulated and on the other hand, the cooling surface formed by the housing for Environment is diminished. It is understood that, if available the suction point for the to be changed oil in the oil reservoir must lie, in which also the opening temperature-dependent controlling Einrichtung, z. As a thermostat, is positioned.
Die Öffnung, welche die beiden Ölreservoire miteinander verbindet, kann im Trennelement ausgebildet sein. Insbesondere kann die Öffnung auch als ein Spalt zwischen dem Getriebegehäuse und dem Trennelement ausgestaltet sein. Besonders für dünnflüssiges heißes Öl kann ein Spalt zwischen dem Getriebegehäuse und dem Trennelement eine ausreichende strömungstechnische Verbindung darstellen, welche fertigungstechnisch einfach umgesetzt werden kann.The opening, which the two oil reservoirs with each other connects, may be formed in the separating element. In particular, can the opening Also designed as a gap between the gear housing and the separator be. Especially for low viscosity hot oil can Gap between the gearbox and the separating element a sufficient fluidic connection represent, which are easily implemented production technology can.
Die zu Beginn einer Aufheizphase erfolgende Erwärmung des Schmieröls kann dadurch weiter beschleunigt werden, dass vorübergehend beide Ölreservoire fluiddicht voneinander getrennt sind. Dies kann mit einer temperaturabhängig steuerbaren Öffnung erreicht werden. Die Öffnung in dem Trennelement kann bei einer definierten Betriebstemperatur des umgewälzten Schmieröls aufgesteuert werden.The at the beginning of a heating phase successful heating of the lubricating oil can This will be further accelerated, that temporarily both oil reservoirs fluid-tightly separated from each other. This can be achieved with a temperature-dependent controllable opening become. The opening in the separating element can at a defined operating temperature of the circulated lubricating oil be turned on.
Das Getriebeöl kann einen Wärmetauscher umströmen. Der Wärmetauscher kann ein plattenförmiges oder wannenförmiges Gebilde sein, das den Ölraum in einen (kleinen) radsatzsseitigen Ölraum und ein (größeres) gehäuseseitiges Ölreservoir trennt.The transmission oil can flow around a heat exchanger. Of the heat exchangers can be a plate-shaped or trough-shaped Be structures that the oil room in a (small) Radsatzsseitigen oil chamber and a (larger) housing-side oil reservoir separates.
Der Wärmetauscher hat eine wärmeabgebende/-aufnehmende Seite in Richtung Radsatz (bewegter Teile) und eine möglichst isolierende Seite in Richtung Gehäuse.Of the heat exchangers has a heat-emitting / -aufnehmende Side towards wheelset (moving parts) and one possible insulating side towards the housing.
Temperaturgesteuerte Klappen (mittels Bimetall, Formgedächtnislegierung oder ähnliches) im Wärmetauscher ermöglichen ab einer bestimmten Öltemperatur eine Strömung zwischen den beiden Ölräumen.temperature-controlled Flaps (by bimetal, shape memory alloy or similar) in the heat exchanger enable from a certain oil temperature a flow between the two oil rooms.
Wie bereits oben ausgeführt, erfolgt somit eine schnellere Ölerwärmung durch kleineres Ölvolumen im bewegten Teil. Außerdem ist eine Isolationsschicht zum Gehäuse vorhanden und es erfolgt eine Reduzierung der Konvektion durch „stehendes” Öl im Reservoir.As already stated above, Thus, a faster oil warming takes place smaller oil volume in the moving part. Furthermore there is an insulation layer to the housing and it takes place a reduction of convection by "standing" oil in the reservoir.
Insbesondere bei einem Geschwindigkeits-Wechselgetriebe mit Tauchschmierung mit in den Schmierölsumpf eintauchenden Zahnrädern kann das plattenförmige Trennelement horizontal ausgerichtet das Gehäuse in ein oberes und ein unteres Ölreservoir unterteilen, wobei das Schmieröl des oberen Ölreservoirs entsprechend umgewälzt wird.Especially in a speed change gearbox with splash lubrication with in the lubricating oil sump immersed gears can the plate-shaped Separator horizontally aligns the housing into an upper and a lower oil reservoir subdivide, with the lubricating oil of the upper oil reservoir is circulated accordingly.
Des Weiteren kann das Trennelement zumindest an seiner dem unteren Ölreservoir zugewandten Oberfläche wärmeisoliert ausgeführt sein. Damit wird ein Wärmeaustausch zwischen den beiden Ölreservoiren über das Trennelement weitgehendst unterbunden und eine noch schnellere Erwärmung des umgewälzten Schmieröles auf Betriebstemperatur erreicht.Of Furthermore, the separating element can at least at its lower oil reservoir facing surface thermally insulated accomplished be. This is a heat exchange between the two oil reservoirs over the Separator largely suppressed and even faster heating of the circulated lubricating oil reached to operating temperature.
In vorteilhafter Weiterbildung der Erfindung kann das plattenförmige Trennelement als ein mit einem Kühlmedium durchströmter Wärmetauscher ausgeführt sein und somit bei baulich günstiger Anordnung zusätzlich zur Konditionierung des Schmieröles beitragen.In an advantageous embodiment of the invention, the plate-shaped separating element can be designed as a flow-through with a cooling medium heat exchanger and thus structurally favorable arrangement in addition to the conditioning of the lubricating oils contribute.
Insbesondere kann der Wärmetauscher mit Kühlwasser der Brennkraftmaschine des Antriebsaggregates durchströmt sein, wobei die Wärmetauscherflächen dem oberen Schmierölanteil zugewandt sind und somit ebenfalls zunächst nur zur Aufheizung des umgewälzten Schmierölanteiles beitragen. Die temperaturabhängige Steuerung der die beiden Ölreservoire verbindenden Öffnung sollte dann so ausgelegt sein, dass spätestens bei Temperaturgleichheit des Kühlmediums und des umgewälzten Schmieröles die Öffnung aufgesteuert wird.Especially can the heat exchanger with cooling water flowed through the internal combustion engine of the drive unit, wherein the heat exchanger surfaces the upper lubricating oil content are facing and thus also initially only for heating the circulated Oil share contribute. The temperature-dependent Control of the two oil reservoirs connecting opening should then be designed so that no later than at temperature equality of cooling medium and the circulated lubricating oil the opening is turned on.
Der Wärmetauscher kann baulich einfach als Röhrenwärmetauscher ausgeführt sein, wobei dessen Kühlwasser führende Rohre an der dem unteren Schmierölreservoir zugewandten, die beiden Reservoire teilenden Trennwand angeordnet sind. Dabei kann die Trennwand kostengünstig aus wärmeisolierendem Material, insbesondere aus Kunststoff, gefertigt sein.Of the heat exchangers can be structurally simple as a tube heat exchanger accomplished be, with its cooling water premier Pipes at the lower oil reservoir facing, the two reservoirs dividing partition arranged are. In this case, the partition can be inexpensively made of heat-insulating material, in particular made of plastic.
Ferner kann zur Erzielung einer vereinfachten Montage der Wärmetauscher über die Rohre hintergreifende Vorsprünge auf die Trennwand aufgeclipst sein.Further can to achieve a simplified installation of the heat exchanger on the Tubes engaging behind projections be clipped on the partition.
Zur Steuerung relativ großer Öffnungsquerschnitte an der Trennwand wird des Weiteren vorgeschlagen, dass die zumindest eine die beiden Reservoire verbindende Öffnung durch zumindest eine in dem Trennelement beziehungsweise in der Trennwand angeordnete Klappe gesteuert ist. Möglich wäre aber auch der Einsatz eines Thermostatventiles, wie sie z. B. in Kühlsystemen von Brennkraftmaschinen vielfach Einsatz finden.to Control of relatively large opening cross sections on the partition is further proposed that the at least an opening connecting the two reservoirs through at least one arranged in the separating element or in the partition wall Flap is controlled. But it would be possible also the use of a thermostatic valve, as z. B. in cooling systems Of internal combustion engines are often used.
Baulich und funktionell besonders vorteilhaft kann jedoch die Klappe zumindest teilweise aus Bimetall oder einem Metall mit einer Formgedächt nislegierung hergestellt sein, die bei einer zunehmenden Erwärmung des Schmieröles in dem oberen Ölreservoir die Öffnung freigibt.structural and functionally particularly advantageous, however, the flap can at least partially made of bimetal or a metal with a shape memory nislegierung be prepared in an increasing heating of the lubricating oil in the upper oil reservoir the opening releases.
Fertigungstechnisch besonders günstig können dabei die Bimetallelemente oder Formgedächtniselemente in die an der Trennwand aus Kunststoff angeformte Klappe integriert sein.manufacturing technology very cheap can while the bimetallic elements or shape memory elements in the on Partition made of plastic molded flap to be integrated.
