Description

Die Erfindung betrifft eine Kühlwasserpumpe für eine Brennkraftmaschine mit innerer Verbrennung mit einem Strömungsleitgehäuse, in dem ein Pumpenlaufrad angeordnet ist, und mit einem vom Strömungsleitgehäuse getrennt ausgeführten Lagerteil, der ein Lager für das Pumpenlaufrad aufweist.The invention relates to a cooling water pump for an internal combustion engine with a flow guide housing, in which a pump impeller is arranged, and with a bearing part executed separately from the flow guide housing, which is a bearing for the pump impeller having.

Kühlwasserpumpen von Brennkraftmaschinen werden üblicherweise als Radial- oder Axial-Radialpumpen ausgeführt. Das Strömungsleitgehäuse solcher Pumpen ist dabei im allgemeinen ein Gußteil aus Aluminium oder einem anderen metallischen Werkstoff.Cooling water pumps of internal combustion engines are usually called radial or axial-radial pumps executed. The flow guide housing of such pumps is generally a cast part made of aluminum or another metallic material.

Aus der EP 0 208 074 A ist eine Wasserpumpe bekannt, bei der einzelne Teile aus Kunststoff hergestellt sind. Eine solche Wasserpumpe besitzt den erheblichen Vorteil einer leichten und kostengünstigen Herstellung, und sie weist im allgemeinen ein geringeres Gewicht auf als eine Wasserpumpe, die aus einem metallischen Werkstoff hergestellt ist. Die geringere Festigkeit von Kunststoff führt jedoch zu relativ gravierenden konstruktiven Beschränkungen und zu Schwierigkeiten, die geforderte Lebensdauer zu erreichen. Weiters müssen aufgrund der geringeren Steifigkeit des Kunststoffmaterials größere Toleranzen zwischen dem Pumpenlaufrad und dem Strömungsleitgehäuse vorgesehen sein, was zu einer Verringerung des Wirkungsgrades und damit zu einer Erhöhung der erforderlichen Antriebsleistung führt.A water pump is known from EP 0 208 074 A, in which individual parts are made of plastic are manufactured. Such a water pump has the considerable advantage of being light and inexpensive to manufacture, and is generally lighter in weight than a water pump made of a metallic material. The lower strength However, plastic leads to relatively serious design restrictions and difficulties in achieving the required lifespan. Furthermore, due to the lower rigidity of the plastic material, greater tolerances between the pump impeller and the flow guide housing can be provided, which leads to a reduction in Efficiency and thus leads to an increase in the required drive power.

Aus der WO 96/03574 ist eine Kühlmittelpumpe bekannt, bei der ein Lagerteil und ein Strömungsleitgehäuse als eigene Bauteile ausgeführt sind. Da jedoch das Strömungsleitgehäuse die auf den Lagerteil wirkenden Kräfte aufnehmen muß, sind der Dimensionierung und der Werkstoffwahl enge Grenzen gesetzt. Ähnliches gilt für die in der EP-A 651 141 gezeigte Lösung.A coolant pump is known from WO 96/03574, in which a bearing part and a flow guide housing are designed as separate components. However, since the flow guide housing the forces acting on the bearing part must be dimensioned and The choice of materials places tight limits. The same applies to the one shown in EP-A 651 141 Solution.

Weiters ist es aus der US 5,040,494 A oder der GB 1 456 938 A bekannt, den Lagerteil und das Strömungsleitgehäuse einstückig auszubilden. Dabei müssen jedoch bei der Formgebung und der Werkstoffwahl Kompromisse eingegangen werden, so daß eine optimale Ausbildung der einzelnen Funktionsteile nicht möglich ist.Furthermore, it is known from US 5,040,494 A or GB 1 456 938 A, the bearing part and to form the flow guide housing in one piece. However, it must be in the design and the choice of materials compromises are made, so that an optimal training of the individual functional parts is not possible.

Aufgabe der vorliegenden Erfindung ist es, eine Kühlwasserpumpe anzugeben, mit der es möglich ist, die Vorteile der Verwendung von Kunststoffmaterialien mit einem einfachen Aufbau und einem hohen Wirkungsgrad zu verbinden.The object of the present invention is to provide a cooling water pump with which it is possible to take advantage of using plastic materials with a simple Construction and a high degree of efficiency.

Erfindungsgemäß ist vorgesehen, daß das Strömungsleitgehäuse zwischen einem Verankerungsteil und dem Lagerteil angeordnet ist, und daß der Lagerteil das Strömungsleitgehäuse umgreift und an dem Verankerungsteil befestigt ist. Wesentlich an der vorliegenden Erfindung ist, daß das von der Form her relativ komplexe Strömungsleitgehäuse einfach und kostengünstig hergestellt werden kann. Insbesonders kann dieses Strömungsleitgehäuse aus Kunststoff, beispielsweise im Spritzgußverfahren, hergestellt sein. Als Verankerungsteil dient beispielsweise der Motorblock oder der Zylinderkopf einer Brennkraftmaschine, an dem die Kühlwasserpumpe direkt befestigt ist. Auf diese Weise gestaltet sich die Kühlwasserversorgung der Brennkraftmaschine besonders einfach. Da der Lagerteil jedoch direkt mit dem Verankerungsteil, also der Brennkraftmaschine oder einem anderen fixen Bauteil verbunden ist, kann die Lagerung des Pumpenlaufrades in besonders steifer und stabiler Weise erfolgen. Der Lagerteil kann als einfacher Gußteil aus Grauguß oder Aluminiumguß ausgebildet sein, der lediglich in einer einzigen Aufspannung auf einer Drehmaschine zu bearbeiten ist. Das Strömungsleitgehäuse braucht bei diesem Aufbau lediglich die zur Abdichtung erforderlichen Kräfte aufnehmen. Es kann daher auch eine erhebliche Gewichtseinsparung erreicht werden.According to the invention it is provided that the flow guide housing between an anchoring part and the bearing part is arranged, and that the bearing part the flow guide housing engages and is attached to the anchoring part. Essential to the present invention is that the relatively complex flow guide housing is simple and inexpensive can be manufactured. In particular, this flow guide housing can Plastic, for example, be made by injection molding. Serves as anchoring part For example, the engine block or the cylinder head of an internal combustion engine, on which the Cooling water pump is attached directly. The cooling water supply is designed in this way the internal combustion engine is particularly simple. However, since the bearing part is directly connected to the anchoring part, is connected to the internal combustion engine or another fixed component, the pump impeller can be stored in a particularly rigid and stable manner. The Bearing part can be designed as a simple cast part made of gray cast iron or cast aluminum can only be machined in a single setup on a lathe. The flow guide housing With this construction, all that is required is for sealing Absorb forces. Considerable weight savings can therefore also be achieved.

In einer besonders begünstigten Ausführungsvariante der Erfindung ist vorgesehen, daß das Strömungsleitgehäuse eine erste und eine zweite Dichtfläche aufweist. Die erste Dichtfläche liegt dabei am Verankerungsteil dichtend an, während die zweite Dichtfläche am Lagerteil dichtend anliegt. Im allgemeinen werden die erste und die zweite Dichtfläche parallel zueinander an gegenüberliegenden Seiten des Strömungsleitgehäuses ausgebildet sein. Auf diese Weise ist eine eigene Befestigung des Strömungsleitgehäuses nicht erforderlich, da dieses zwischen dem Verankerungsteil und dem Lagerteil gehalten wird.In a particularly preferred embodiment of the invention it is provided that the Flow guide housing has a first and a second sealing surface. The first sealing surface lies sealingly on the anchoring part, while the second sealing surface lies on the bearing part fits tightly. Generally, the first and second sealing surfaces are parallel to each other be formed on opposite sides of the flow guide housing. To this A separate attachment of the flow guide housing is not necessary as this is held between the anchoring part and the bearing part.

Besonders günstig ist es, wenn in dem Strömungsleitgehäuse Nuten zur Aufnahme von Dichtungselementen zur Abdichtung gegenüber dem Verankerungsteil und/oder dem Lagerteil vorgesehen sind. Dies ermöglicht eine weitere Vereinfachung bei der Herstellung.It is particularly advantageous if grooves for receiving sealing elements are located in the flow guide housing for sealing against the anchoring part and / or the bearing part are provided. This enables a further simplification in the manufacture.
