Description

Die Erfindung betrifft eine Wasserpumpe für den Kühlwasser­ kreislauf eines Verbrennungsmotors für Kraftfahrzeuge, die von einem Elektromotor angetrieben ist.The invention relates to a water pump for the cooling water Circuit of an internal combustion engine for motor vehicles, the is driven by an electric motor.

Es ist allgemein bekannt, die Kühlflüssigkeit im Kreislauf eines wassergekühlten Verbrennungsmotors von Kraftfahrzeugen durch Pumpen zu fördern, die über einen Keilriemen vom Verbrennungsmotor angetrieben werden. In letzter Zeit geht man jedoch vermehrt dazu über, die Wasserpumpe durch einen separaten Elektromotor anzutreiben, um das Kühlsystem besser steuern bzw. regeln zu können.It is well known that the coolant is in the circuit of a water-cooled internal combustion engine from Promote motor vehicles by pumps that have a V-belts are driven by the internal combustion engine. In Lately, however, there has been an increasing trend towards the To drive the water pump by a separate electric motor, to better control the cooling system.

Dabei stellt der Elektromotor ein zusätzliches Bauteil dar, welches in dem stark begrenzten Platz des Motorraums untergebracht werden muß, was oftmals wegen der Vielzahl der hier angeordneten Aggregate und Bauteile schwierig ist. The electric motor is an additional component which in the very limited space of the engine compartment Must be accommodated, which is often because of the large number the aggregates and components arranged here is difficult.  

Ein weiteres Problem stellt die hierbei erforderliche Kühlung der Elektronik des Elektromotors dar.Another problem is that which is required here Cooling the electronics of the electric motor.

Aufgabe der Erfindung ist es daher, eine konstruktiv einfache, preiswerte und leicht handhabbare Wasserpumpe der eingangs genannten Art zu schaffen, die platzsparend im Motorraum untergebracht werden kann und eine einfache Kühlung der Elektronik des Elektromotors ermöglicht.The object of the invention is therefore a constructive simple, inexpensive and easy to use water pump to create the kind mentioned in the space-saving Engine compartment can be accommodated and a simple one Cooling the electronics of the electric motor allows.

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung nach Anspruch 1 gelöst. Wesentlicher Vorteil ist dabei, daß die Pumpe mit dem Elektromotor vollständig innerhalb der Leitungen und/oder der Behälter des Kühlwasserkreislaufs angeordnet ist.This object is achieved by a device solved according to claim 1. The main advantage is that the pump with the electric motor completely inside the Pipes and / or the container of the cooling water circuit is arranged.

Bei einfacher Konstruktion und Montage wird auf diese Weise eine kostengünstige und platzsparende Möglichkeit zur Anordnung der Pumpe sowie des die Pumpe antreibenden Elektromotors geschaffen. Im Vergleich zu herkömmlichen Anordnungen der Wasserpumpe wird hierdurch sogar weniger Bauraum beansprucht.With simple construction and assembly this way an inexpensive and space-saving way to Arrangement of the pump and the one driving the pump Electric motor created. Compared to conventional ones Arrangements of the water pump thereby become even less Space required.

Gleichzeitig wird auf besonders einfache Weise der Elektromotor bzw. seine Elektronik durch die geförderte Kühlflüssigkeit gekühlt.At the same time, the Electric motor or its electronics funded by the Cooled coolant.

Ein weiterer Vorteil besteht darin, daß der Betrieb der Wasserpumpe geringere Geräusche verursacht, da die umgebende Kühlflüssigkeit die Geräusche dämpft.Another advantage is that the operation of the Water pump causes less noise because the surrounding coolant dampens the noise.

Die Wasserpumpe kann vorzugsweise in einer Rohrverdickung der Kühlleitung oder in einem in den Kühlwasserkreislauf eingesetzten Behälter angeordnet sein. The water pump can preferably be in a pipe thickening the cooling line or in a in the cooling water circuit used container be arranged.  

Die Wasserpumpe kann in einer bevorzugten Ausführungsform in dem Ausgleichsbehälter des Kühlkreislaufs angeordnet sein. Der Ausgleichsbehälter ist üblicherweise so groß dimensioniert, daß die Pumpe und der Elektromotor vollständig darin untergebracht sein können. Außerdem wird hier eine besonders gute Kühlwirkung für die Motor­ elektronik erzielt.In a preferred embodiment, the water pump can arranged in the expansion tank of the cooling circuit his. The expansion tank is usually this large dimensioned that the pump and the electric motor can be completely housed in it. Besides, will here a particularly good cooling effect for the engine electronics achieved.

Besonders vorteilhaft ist es dabei ferner, wenn die Pumpe in den Ausgleichsbehälter eingesetzt und lösbar darin befestigt ist. Auf diese Weise wird die Möglichkeit einer besonders leichten Montage und Demontage, z. B. für Wartungsarbeiten, geschaffen.It is also particularly advantageous if the pump inserted in the expansion tank and detachable therein is attached. This way the possibility of a particularly easy assembly and disassembly, e.g. B. for Maintenance work, created.

Besonders vorteilhaft ist es, wenn als Wasserpumpe eine Tauchpumpe verwendet wird, die das Kühlwasser aus dem die Pumpe umgebenen Leitungsbereich bzw. Behälter ansaugt. Dadurch werden auf besonders einfache Weise Leckverluste vermieden, die beim saugseitigen Anschluß herkömmlicher Wasserpumpen auftreten können.It is particularly advantageous if a Submersible pump is used to extract the cooling water from the Sucks in the surrounding pipe area or container. Leakage losses are thereby particularly simple avoided the more conventional connection on the suction side Water pumps can occur.

Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den Unteransprüchen sowie aus der nachfolgenden Beschreibung und dem in der Zeichnung dargestellten Ausführungsbeispiel.Further advantages and features of the invention result from the subclaims and from the following Description and that shown in the drawing Embodiment.

Die Figur zeigt den Ausgleichsbehälter 1 eines nicht näher dargestellten Kühlkreislaufsystems eines Verbrennungsmotors für Kraftfahrzeuge. In dem Ausgleichsbehälter 1 ist eine Tauchpumpe 2 angeordnet, die von einem Elektromotor 3 angetrieben wird. Die Tauchpumpe 2 ist über Stützen 4 an der Innenseite des Bodens 5 des Ausgleichsbehälters 1 befestigt, so daß die Kühlflüssigkeit 6 frei zwischen der Tauchpumpe 2 und dem Boden 5 zirkulieren kann.The figure shows the expansion tank 1 of a cooling circuit system, not shown, of an internal combustion engine for motor vehicles. An immersion pump 2 , which is driven by an electric motor 3 , is arranged in the expansion tank 1 . The submersible pump 2 is fastened to the inside of the base 5 of the expansion tank 1 via supports 4 , so that the cooling liquid 6 can circulate freely between the submersible pump 2 and the base 5 .

In dem unter dem Elektromotor 3 angeordneten Pumpengehäuse 7 ist ein Laufrad 8 auf der vertikal ausgerichteten Welle 9 des Elektromotors 3 angeordnet, das die Kühlflüssigkeit 6 durch einen nach unten gerichteten Ansaugstutzen 10 axial ansaugt. Sodann wird die Kühlflüssigkeit 6 durch einen Kanal 11 nach oben gepumpt, der an das Spiralgehäuse 12 angeschlossen ist.In the pump housing 7 arranged under the electric motor 3 , an impeller 8 is arranged on the vertically oriented shaft 9 of the electric motor 3 , which axially sucks in the cooling liquid 6 through a downward-directed intake port 10 . The cooling liquid 6 is then pumped up through a channel 11 which is connected to the volute casing 12 .

Das obere Ende des Kanals 11 ist durch den Deckel 13 des Ausgleichsbehälters 1 hindurchgeführt und bildet den Druckstutzen 14 für den weiteren Kreislauf.The upper end of the channel 11 is passed through the cover 13 of the expansion tank 1 and forms the pressure port 14 for the further circuit.

Durch den Einlaufstutzen 15 wird die Kühlflüssigkeit 6 am Ende des Kühlkreislaufs wieder in den Ausgleichsbehälter 1 zurückgeführt. Nicht nur die Tauchpumpe 2 sondern auch der Elektromotor 3 ist vollständig innerhalb des Ausgleichs­ behälters 1 angeordnet und von Kühlflüssigkeit 6 umgeben bzw. umströmt. Dadurch wird eine optimale Kühlung des Elektromotors 3 und seiner Elektronik gewährleistet.At the end of the cooling circuit, the coolant 6 is returned to the expansion tank 1 through the inlet connection 15 . Not only the submersible pump 2 but also the electric motor 3 is arranged entirely within the compensation tank 1 and surrounded or flowed around by cooling liquid 6 . This ensures optimal cooling of the electric motor 3 and its electronics.
