Abstract
Description
Die Erfindung betrifft eine Unterdruckversorgungseinrichtung für mindestens einen Verbraucher in einem Kraftfahrzeug gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a vacuum supply device for at least a consumer in a motor vehicle according to the preamble of the claim 1.
In Kraftfahrzeugen wird Unterdruck primär zur Bremskraftverstärkung und sekundär zum Betrieb diverser sonstiger Verbraucher benötigt. Es ist bekannt, den vom Verbrennungsmotor im Ansaugtrakt erzeugten Unterdruck zur Versorgung der Verbraucher zu nutzen. Ferner werden vom Verbrennungsmotor mechanisch angetriebene, nass laufende Unterdruckpumpen zur Versorgung der Verbraucher mit Unterdruck bereitgestellt. Zusätzlich ist es bekannt, elektrisch angetriebene, trocken laufende Unterdruckpumpen als Zusatzpumpen für bestimmte Betriebssituationen einzusetzen, in denen der Verbrennungsmotor im Ansaugtrakt, oder die vom Verbrennungsmotor angetriebene Unterdruckpumpe nicht den benötigten Unterdruck bereitstellen können. Solche Betriebssituationen sind beispielsweise der Start-Stop-Betrieb des Verbrennungsmotors oder ein Kaltstart mit offener Drosselklappe zur Katalysatorheizung. Die elektrisch betriebene Unterdruckpumpe ist dabei parallel zu der mechanisch vom Verbrennungsmotor angetriebenen Unterdruckpumpe bzw. parallel zu einer Unterdruckversorgungsleitung zwischen Verbraucher und Ansaugtrakt angeordnet.In Automobiles is negative pressure primarily to the brake booster and secondary needed for the operation of various other consumers. It is known that of the Combustion engine in the intake tract generated negative pressure for supply the consumer to use. Furthermore, the internal combustion engine becomes mechanical powered, wet running vacuum pumps to supply the Consumer provided with negative pressure. In addition, it is known electrically driven, dry running vacuum pumps as additional pumps for certain operating situations in which the internal combustion engine in the intake system, or the driven by the engine vacuum pump not the required Can provide negative pressure. Such operating situations are, for example, the start-stop operation of the internal combustion engine or a cold start with open throttle for catalyst heating. The electrically operated vacuum pump is parallel to the mechanically driven by the internal combustion engine Vacuum pump or parallel to a vacuum supply line between Consumer and intake tract arranged.
Die elektrisch betriebenen Unterdruckpumpen nach dem Stand der Technik haben aufgrund ihrer Ausführung als trocken laufende Pumpe einen schlechteren Wirkungsgrad bei Evakuierung unter 200 mbar Absolutdruck im Vergleich zu den herkömmlichen am Verbrennungsmotor angebauten mechanischen Unterdruckpumpen, die durch ihre Ölschmierung und die dadurch erreichte Spaltabdichtung einen höheren Wirkungsgrad erzielen. Hieraus folgen längere Evakuierungszeiten und damit eine reduzierte Bremskraft-Unterstützung in bestimmten Fahrsituationen sowie längere Laufzeiten der elektromotorischen Unterdruckpumpe mit der Folge hoher Kosten zur Gewährleistung der benötigten Lebensdauer.The electrically operated vacuum pumps according to the prior art have because of their execution as dry running pump a worse efficiency in evacuation below 200 mbar absolute pressure compared to the conventional ones mounted on the internal combustion engine mechanical vacuum pumps, the through their oil lubrication and the gap seal achieved thereby a higher efficiency achieve. From this follow longer ones Evacuation times and thus a reduced braking force support in certain driving situations as well as longer terms of the electromotive Vacuum pump resulting in high costs to ensure the needed Lifespan.
Aufgabe und Vorteile der Erfindungtask and advantages of the invention
Der Erfindung liegt die Aufgabe zugrunde eine verbesserte Unterdruckversorgungseinrichtung mit einer Unterdruckpumpe mit reduzierter Laufzeit bereitzustellen.Of the Invention is the object of an improved vacuum supply device with To provide a vacuum pump with reduced transit time.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.These The object is achieved with the features of claim 1. advantageous Further developments of the invention are specified in the subclaims.
Der Erfindung liegt der Gedanke zugrunde, die Unterdruckpumpe in Reihe zwischen dem Verbraucher und der Unterdruckquelle anzuordnen. Dabei ist der Eingang der Unterdruckpumpe mit einem Verbraucher, insbesondere einem Bremskraftverstärker, verbunden, wodurch Luft aus diesem abgesaugt wird. Der Ausgang der Pumpe ist im Gegensatz zum Stand der Technik nicht mit der Atmosphäre, sondern mit der Vakuumquelle, insbesondere dem Ansaugtrakt des Verbrennungsmotors, verbunden. Hierdurch fördert die Unterdruckpumpe die von den Verbrauchern angesaugte Lauft nicht gegen die Atmosphäre, sondern gegen das von der Unterdruckquelle bereit gestellte Unterdruckniveau. Hierdurch liegt eine geringere Druckdifferenz zwischen Saugseite und Druckseite der Unterdruckpumpe an, wodurch die Laufzeit der Unterdruckpumpe erheblich reduziert wird, wodurch sich wiederum die Lebensdauer der Unterdruckpumpe verlängert. Ferner resultiert aus der erfindungsgemäßen Unterdruckversorgungseinrichtung eine Laufgeräuschreduzierung, da die von der Unterdruckpumpe erzeugten Schallwellen nicht unmittelbar nach außen, sondern in die Unterdruckquelle geleitet werden.Of the Invention is based on the idea, the vacuum pump in series between the consumer and the vacuum source to arrange. there is the input of the vacuum pump with a consumer, in particular a brake booster, connected, whereby air is sucked out of this. The output of the Pump is in contrast to the prior art not with the atmosphere, but with the vacuum source, in particular the intake tract of the internal combustion engine, connected. This promotes the vacuum pump does not run the sucked by the consumer against the atmosphere, but against the provided by the vacuum source vacuum level. This results in a lower pressure difference between the suction side and Pressure side of the vacuum pump, whereby the duration of the vacuum pump is significantly reduced, which in turn reduces the life the vacuum pump extended. Furthermore, results from the vacuum supply device according to the invention a noise reduction, because the sound waves generated by the vacuum pump not directly outward, but be directed into the vacuum source.
Die Verwendung des Ansaugtraktes als Unterdruckquelle kann insbesondere bei Benzin-Motoren, die bei Kraftfahrzeugen mit Hybrid-Antrieb vorzugsweise zum Einsatz kommen, eingesetzt werden. Auch lässt sich der Ansaugtrakt bei Direkteinspritzer-Motoren als Unterdruckquelle nutzen, wenn auch der Unterdruck im Ansaugtrakt bei derartigen Motoren reduziert ist.The Use of the intake tract as a vacuum source can in particular in gasoline engines, preferably in motor vehicles with hybrid drive be used, are used. Also, the intake can be at Direct-injection engines use as a vacuum source, although the negative pressure in the intake system is reduced in such engines.
Wenn als Unterdruckpumpe eine elektromotorisch angetriebene, insbesondere trocken laufende, Pumpe eingesetzt wird, eignet sich die erfindungsgemäße Unterdruckversorgungseinrichtung insbesondere für den Einsatz in Kraftfahrzeugen mit Hybrid-Antrieb. Durch die erfindungsgemäße Anordnung der elektromotorisch betriebenen Unterdruckpumpe werden deren Nachteile, wie insbesondere der schlechtere Wirkungsgrad, kompensiert. Die elektromotorisch angetriebene Unterdruckpumpe muss nur eine geringe Druckdifferenz überwinden, wodurch die Laufzeit gegenüber einer herkömmlichen Parallelanordnung verringert ist.If as a vacuum pump an electric motor driven, in particular dry running, pump is used, the vacuum supply device according to the invention is particularly suitable for the Use in motor vehicles with hybrid drive. By the arrangement according to the invention the electric motor operated vacuum pump are the disadvantages, especially the worse efficiency, compensated. The electric motor driven vacuum pump only has to overcome a small pressure difference, thereby the duration compared to a conventional one Parallel arrangement is reduced.
In Weiterbildung der Erfindung ist vorgesehen, dass zur Steuerung der Unterdruckpumpe mindestens ein mit einer Regelungs- und/oder Steuerungseinrichtung verbundener Unterdrucksensor vorgesehen ist. Dieser Unterdrucksensor ist bevorzugt auf der Saugseite der Unterdruckpumpe angeordnet und misst somit den am Verbraucher anliegenden Unterdruck. Wird eine vorgegebene Abschaltschwelle, z.B. 150 mbar Absolutdruck unterschritten, wird die Unterdruckpumpe abgeschaltet. Überschreitet der von dem Unterdrucksensor gemessene Absolutdruck eine vorgegebene obere Einschaltschwelle von z.B. 330 mbar, wird die Pumpe wieder eingeschaltet.In Further development of the invention is provided that for the control of Vacuum pump at least one with a control and / or control device connected vacuum sensor is provided. This vacuum sensor is preferably arranged on the suction side of the vacuum pump and thus measures the negative pressure applied to the consumer. Will one predetermined switch-off threshold, e.g. 150 mbar absolute pressure fell below, the vacuum pump is switched off. Exceeds that of the vacuum sensor measured absolute pressure a predetermined upper switch-on threshold of e.g. 330 mbar, the pump is switched on again.
Um in Betriebssituationen, in denen die Vakuum-Saugleistung des Verbrennungsmotors im Ansaugtrakt größer ist als die Vakuum-Saugleistung der Unterdruckpumpe eine Drosselung durch die in Reihe geschaltete Unterdruckpumpe zu verhindern, ist in Ausgestaltung der Erfindung eine Bypass-Leitung vorgesehen, die unter Umgehung der Unterdruckpumpe die Unterdruckquelle, insbesondere den Ansaugtrakt des Verbrennungsmotors, direkt mit dem Verbraucher, insbesondere dem Bremskraftverstärker, verbindet. Durch diese erfindungsgemäße Ausgestaltung der Unterdruckversorgungseinrichtung kann die Laufleistung des Verbrennungsmotors in bestimmten Betriebssituationen, beispielsweise unmittelbar nach dem Start des Verbrennungsmotors bei niedrigem Vakuumniveau, ohne Drosselverluste genutzt werden.Around in operating situations in which the vacuum suction power of the internal combustion engine is larger in the intake tract as the vacuum suction power the vacuum pump throttling through the series-connected To prevent vacuum pump is in an embodiment of the invention a bypass line is provided, bypassing the vacuum pump the vacuum source, in particular the intake tract of the internal combustion engine, connects directly to the consumer, in particular the brake booster. By this embodiment of the invention the vacuum supply device can the mileage of the internal combustion engine in certain operating situations, for example immediately after the start of the engine at low vacuum level, without Throttling losses are used.
Um das Vakuumniveau in den Verbrauchern bei abgeschaltetem Verbrennungsmotor oder bei höherer Saugleistung der elektromotorisch betriebenen Unterdruckpumpe zu erhalten, ist in Ausgestaltung der Erfindung mit Vorteil ein Rückschlagventil innerhalb der Bypassleitung angeordnet.Around the vacuum level in the consumers when the internal combustion engine is switched off or at higher Suction power of the electric motor operated vacuum pump obtained is in an embodiment of the invention advantageously a check valve arranged within the bypass line.
Bevorzugt ist ebenfalls ein Rückschlagventil in der Verbindungsleitung zwischen Unterdruckpumpe und Verbraucher angeordnet, damit das Vakuumniveau im Verbraucher auch bei abgeschalteter Unterdruckpumpe aufrechterhalten werden kann.Prefers is also a check valve in the connecting line between vacuum pump and consumer arranged so that the vacuum level in the consumer even when switched off Vacuum pump can be maintained.
Gemäß einer vorteilhaften Weiterbildung der Erfindung ist auf der Druckseite der Unterdruckpumpe mindestens ein Unterdruckreservoir vorgesehen. Dieses dient dazu, bei Stillstand des Verbrennungsmotors, insbesondere bei Kraftfahrzeugen mit Hybrid-Antrieb, einen Unterdruck auf der Druckseite der Unterdruckpumpe zu erhalten, um die Laufzeit der Unterdruckpumpe auch bei abgeschaltetem Verbrennungsmotor zu reduzieren.According to one advantageous development of the invention is on the pressure side the vacuum pump provided at least one vacuum reservoir. This serves to stop the internal combustion engine, in particular in motor vehicles with hybrid drive, a negative pressure on the Pressure side of the vacuum pump to get the duration of the vacuum pump even when the internal combustion engine is switched off.
