Abstract
Description
Die Erfindung betrifft die Anordnung einer elektrischen Unterdruckpumpe für Unterdruckverbraucher an Kraftfahrzeugen.The invention relates to the arrangement an electric vacuum pump for vacuum consumers Motor vehicles.
An Kraftfahrzeugen mit Verbrennungsmotoren ist es gängige Praxis, die Kraftfahrzeug-Bremsanlage mit einem unterdruckbetätigten Bremskraftverstärker auszurüsten.On motor vehicles with internal combustion engines it is common Practice, the motor vehicle braking system with a vacuum operated Brake booster equip.
Der Unterdruck wird dabei im allgemeinen aus dem Unterdruck im Saugrohr und mittels sogenannter motorabhängiger Unterdruckpumpen, auch als Vakuumpumpen bezeichnet, erzeugt.The vacuum is generally from the vacuum in the intake manifold and by means of so-called engine-dependent vacuum pumps, also referred to as vacuum pumps.
Aus der
Aus diesem Grunde ist es angezeigt, statt dessen oder zusätzlich zur motorabhängigen Unterdruckversorgung bzw. zu den motorabhängigen Unterdruckpumpen eine oder mehrere motorunabhängige, beispielsweise elektrisch betriebene Unterdruckpumpen zu nutzen.For this reason, it is appropriate instead or in addition for engine dependent Vacuum supply or to the motor-dependent vacuum pumps or more engine independent, For example, to use electrically operated vacuum pumps.
In der Praxis werden diese elektrisch betriebenen Unterdruckpumpen an einem tragenden Bauteil der Fahrzeugkarosserie, beispielsweise im Bereich des Motorraums an einem Hilfsrahmen fest angeordnet.In practice, these become electric operated vacuum pumps on a load-bearing component of the vehicle body, for example in the area of the engine compartment on a subframe arranged.
Diese Anbindung direkt an die Kraftfahrzeugkarosserie hat den wesentlichen Nachteil, dass störende Pumpengeräusche nahezu ungehindert in die Fahrgastzelle eindringen können, wodurch im Ergebnis erhebliche Aufwendungen für die akustische Entkoppelung der Unterdruckpumpe von der Kraftfahrzeugkarosserie erforderlich sind.This connection directly to the vehicle body has the main disadvantage that annoying pump noise almost can enter the passenger compartment unhindered, which results in considerable expenses for the acoustic decoupling of the vacuum pump from the vehicle body required are.
Hier setzt die nachfolgend beschriebene Erfindung an.Here is the one described below Invention.
Aufgabe der Erfindung ist es, in Verbesserung des Standes der Technik eine Anordnung einer elektrisch betriebenen Unterdruckpumpe an Kraftfahrzeugen zu schaffen, die weitestgehend das Eindringen von Pumpengeräuschen in die Fahrgastzelle ohne zusätzliche kosten- und materialintensive Aufwendungen vermeidet.The object of the invention is in Improving the prior art an electrical arrangement operated vacuum pump to create motor vehicles that largely penetration of pump noise into the passenger compartment without additional avoids costly and material-intensive expenses.
Erfindungsgemäß wird die Aufgabe in Verbindung mit den Merkmalen im Oberbegriff des Anspruchs 1 dadurch gelöst, dass die elektrische Unterdruckpumpe innerhalb des Motorraums des Kraftfahrzeugs an einem massereichen Aggregat desselben angeordnet und mit diesem fest verbunden ist. Als massereiche Aggregate sind dabei insbesondere der Getriebeblock und/oder Motorblock vorgesehen.According to the invention, the task is related solved with the features in the preamble of claim 1 in that the electric vacuum pump inside the engine compartment of the motor vehicle arranged on a massive unit and with it is firmly connected. The massive aggregates are in particular the Gear block and / or engine block provided.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist die elektrische Unterdruckpumpe in großem Abstand zur Fahrgastzelle, vorzugsweise im vorderen Drittel des Motorraums angeordnet.According to an advantageous embodiment the invention is the electrical vacuum pump at a large distance to the passenger compartment, preferably in the front third of the engine compartment arranged.
Die vorgeschlagene Anordnung hat im Hinblick auf eine herkömmliche Befestigung der Unterdruckpumpe direkt an der Kraftfahrzeugkarosserie den wesentlichen Vorteil, dass durch die große Masse des Getriebes und/oder Motors und deren bereits vorhandene Entkoppelung von der Kraftfahrzeugkarosserie vermittels an sich bekannter Entkoppelungsgummis die Weiterleitung des Körperschalls infolge des Betriebs der Unterdruckpumpe unterbrochen respektive unterdrückt wird. Was die Problematik des Luftschalls anbelangt, wird diesem wirkungsvoll dadurch begegnet, dass die Unterdruckpumpe zum einen beabstandet zur Fahrgastzelle angeordnet ist und zum anderen vorteilhaft die vorhandene Motorkapselung genutzt werden kann.The proposed arrangement has in terms of a conventional one Attachment of the vacuum pump directly to the vehicle body significant advantage that the large mass of the gear and / or Motors and their existing decoupling from the motor vehicle body forwarding by means of known decoupling rubbers of structure-borne noise interrupted due to the operation of the vacuum pump, respectively repressed becomes. As for the problem of airborne noise, this becomes countered effectively by the fact that the vacuum pump on the one hand is arranged at a distance from the passenger compartment and is also advantageous the existing motor encapsulation can be used.
