Abstract

In a liquid cooling circuit for an internal combustion engine the pumped liquid flows from a liquid pump (2) with a pump housing (4) fixed on a front face of the engine housing (6) into a cover passage (8) formed by a front end cover (9). In order to avoid a seal face (15) between the pump housing and the front end cover, which is difficult to achieve, a tunnel-like connecting passage (13) is arranged in the engine housing between the liquid pump (2) and the cover passage (8), above which connecting passage the seal faces (15, 16) of the pump housing and the front end cover, separated from one another, run with the engine housing. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Flüssigkeitsführung für eine Brennkraftmaschine gemäß den im Oberbegriff des Patentanspruchs 1 genannten Merkmalen.The invention relates to a fluid guide for an internal combustion engine according to the features mentioned in the preamble of claim 1.

Eine derartige Flüssigkeitsführung ist aus der DE 25 02 034 A1 bekannt. In dieser Schrift wird es als nachteilig angesehen, eine Ölpumpe und einen Stirndeckel als Einzelteile am Brennkraftmaschinengehäuse anzuordnen, da bei einer Förderung des Öls von der Ölpumpe in die Kanäle des Stirndeckels die Verbindung zwischen den beiden schwierig abzudichten ist und eine Ölleckage eintritt. Als Abhilfe schlägt diese Schrift ein gemeinsames Gehäuse für Ölpumpe und Stirndeckel vor. Hierdurch ergeben sich jedoch die Nachteile, daß ein Austausch der Pumpe nur gemeinsam mit dem Stirndeckel möglich ist und die Verwendung unterschiedlicher Pumpen verhindert wird.Such a liquid guide is known from DE 25 02 034 A1. In this document, it is considered disadvantageous to arrange an oil pump and a front cover as individual parts on the internal combustion engine housing, since when the oil is pumped from the oil pump into the channels of the front cover, the connection between the two is difficult to seal and oil leakage occurs. As a remedy, this document suggests a common housing for the oil pump and front cover. However, this results in the disadvantages that the pump can only be replaced together with the end cover and the use of different pumps is prevented.

Der Erfindung liegt die Aufgabe zugrunde, bei einer gattungsgemäßen Flüssigkeitsführung eine sichere Abdichtung für die Flüssigkeit auch bei einer getrennten Ausbildung von Flüssigkeitspumpe und Stirndeckel zu erreichen.The invention has for its object to achieve a secure seal for the liquid with a generic liquid guide even with a separate design of the liquid pump and the front cover.

Diese Aufgabe ist bei einer gattungsgemäßen Flüssigkeitsführung durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.This object is achieved in a generic liquid guide by the characterizing features of claim 1.

Bei der erfindungsgemäßen Flüssigkeitsführung sind die Flüssigkeitspumpe und der Stirndeckel als Einzelteile ausgebildet mit den Vorteilen einer getrennten Austauschbarkeit und der Möglichkeit einer Verwendung unterschiedlicher Flüssigkeitspumpen, ohne daß sich die Notwendigkeit einer schwierig zu verwirklichenden Abdichtung unmittelbar zwischen Flüssigkeitspumpe und Stirndeckel ergibt. Die tunnelartige Verbindung innerhalb des Brennkraftmaschinengehäuses zwischen der Flüssigkeitspumpe und dem Deckelkanal läßt getrennte, leicht abzudichtende Trennflächen der Flüssigkeitspumpe und des Stirndeckels mit dem Brennkraftmaschinengehäuse zu, die nebeneinander quer oberhalb dieser tunnelartigen Verbindung verlaufen.In the liquid guide according to the invention, the liquid pump and the front cover are designed as individual parts with the advantages of separate interchangeability and the possibility of using different liquid pumps without the necessity of a seal which is difficult to implement directly between the liquid pump and the front cover. The tunnel-like connection within the internal combustion engine housing between the liquid pump and the cover channel allows separate, easy-to-seal separating surfaces of the liquid pump and the front cover with the internal combustion engine housing, which run alongside one another transversely above this tunnel-like connection.

Die Ausführung gemäß dem Patentanspruch 2 ermöglicht eine besonders kostengünstige Austauschbarkeit einer Kühlmittelpumpe, da lediglich die einem Verschleiß ausgesetzten beweglichen Teile und das diese tragende Pumpengehäuseteil getrennt vom Maschinengehäuse ausgeführt sind.The embodiment according to claim 2 enables a particularly cost-effective interchangeability of a coolant pump, since only the movable parts exposed to wear and the pump housing part carrying them are designed separately from the machine housing.

Im Patentanspruch 3 ist eine neben der Weiterleitung der Flüssigkeit zusätzliche Nutzung des Deckelkanals als Aufnahme eines Ölkühlers angegeben, wobei in den Ansprüchen 4 und 5 dessen besonders günstige Anordnung und Durchströmung dargestellt ist.In claim 3, in addition to the forwarding of the liquid, additional use of the cover channel for receiving an oil cooler is specified, claims 4 and 5 depicting its particularly favorable arrangement and flow.

Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Dabei zeigt:

eine Teil-Stirnansicht eines Brennkraftmaschinengehäuses im Bereich einer Kühlmittelpumpe und
Fig. 2
einen Schnitt durch das Maschinengehäuse nach der Linie II-II der Fig. 1 mit zugehörigem Pumpengehäuse und Stirndeckel.
The invention is explained in more detail below with reference to an embodiment shown in the drawing. It shows:
Fig. 1
a partial front view of an internal combustion engine housing in the area of a coolant pump and
Fig. 2
a section through the machine housing along the line II-II of FIG. 1 with the associated pump housing and end cover.

Kühlmittel zur Kühlung einer Brennkraftmaschine wird von einem Pumpenrad 1 einer Kühlmittelpumpe 2 gefördert, das über eine Riemenscheibe 3 angetrieben wird und in einem Pumpengehäusedeckel 4 mittels einer Welle 5 gelagert ist. Die Kühlmittelpumpe 2 ist in Spiralbauweise ausgeführt mit im Maschinengehäuse 6 der Brennkraftmaschine gelegenem Spiralkanal 7, der durch den Pumpengehäusedeckel 4 abgedeckt ist, der stirnseitig an das Maschinengehäuse 6 angeschraubt ist.Coolant for cooling an internal combustion engine is conveyed by a pump wheel 1 of a coolant pump 2, which is driven via a pulley 3 and is mounted in a pump housing cover 4 by means of a shaft 5. The coolant pump 2 is designed in a spiral construction with a spiral channel 7 located in the machine housing 6 of the internal combustion engine, which is covered by the pump housing cover 4, which is screwed onto the front of the machine housing 6.

Das Kühlmittel wird aus dem Spiralkanal 7 in einen Deckelkanal 8 gefördert, der durch das Maschinengehäuse 6 und einen stirnseitig an diesem angeschraubten Stirndeckel 9 gebildet wird. Im Deckelkanal 8 ist ein am Stirndeckel 9 angeschraubter, in das stirnseitige Maschinengehäuse 6 teilweise hineinragender Ölkühler 10 zur Kühlung von Schmieröl durch das Kühlmittel angeordnet, das dann aus dem Ölkühler 10 in einen Längskanal 11 und zu den einzelnen Zylindern 12 im Maschinengehäuse 6 geführt wird.The coolant is conveyed out of the spiral duct 7 into a cover duct 8, which is formed by the machine housing 6 and an end cover 9 screwed to the end face of the latter. In the cover channel 8, an oil cooler 10, screwed onto the end cover 9 and partially protruding into the front-side machine housing 6, is arranged for cooling lubricating oil by the coolant, which is then guided from the oil cooler 10 into a longitudinal channel 11 and to the individual cylinders 12 in the machine housing 6.

Spiralkanal 7 und Deckelkanal 8 sind durch einen Verbindungskanal 13 hydraulisch miteinander verbunden, der tunnelartig innerhalb des Maschinengehäuses 6 liegt. Zur Stirnseite der Brennkraftmaschine hin wird der Verbindungskanal 13 durch ein Wandteil 14 als Teil des Maschinengehäuses 6 begrenzt, der die voneinander getrennten Dichtflächen 15, 16 sowohl für den Pumpengehäusedeckel 4 als auch für den Stirndeckel 9 trägt. Damit wird eine schwierig zu verwirklichende unmittelbare Abdichtung zwischen Pumpengehäusedeckel 4 und Stirndeckel 9 vermieden, gleichzeitig kann der Pumpengehäusedeckel 4 mitsamt dem Pumpenrad 1 leicht ausgetauscht werden.Spiral channel 7 and cover channel 8 are hydraulically connected to one another by a connecting channel 13, which lies inside the machine housing 6 in a tunnel-like manner. Towards the front of the internal combustion engine, the connecting duct 13 is delimited by a wall part 14 as part of the machine housing 6, which carries the mutually separated sealing surfaces 15, 16 both for the pump housing cover 4 and for the end cover 9. This avoids a difficult seal to be realized between the pump housing cover 4 and the end cover 9, at the same time the pump housing cover 4 together with the pump wheel 1 can be easily replaced.

Die Mündung 17 des Verbindungskanal 13 in den Deckelkanal 8 liegt etwa in der Trennebene 18 zwischen Maschinengehäuse 6 und Stirndeckel 9. Die Strömung in diesem Bereich wird durch eine gekrümmte Rippe 19 des Maschinengehäuses 6 so umgelenkt, daß die Strömungsrichtung im Bereich der Mündung 17 etwa senkrecht zur Trennebene 18 liegt und damit eine Kurzschlußströmung in den Längskanal 11 weitgehend verhindert wird. Das Kühlmittel durchströmt anschließend mit zweimaliger Umlenkung den Ölkühler 10 teils in dessen Längs- und teils in dessen Querrichtung, so daß eine gute Kühlwirkung in diesem gewährleistet ist.The mouth 17 of the connecting channel 13 in the cover channel 8 lies approximately in the parting plane 18 between the machine housing 6 and the end cover 9. The flow in this area is determined by a curved rib 19 of the machine housing 6 deflected so that the flow direction in the region of the mouth 17 is approximately perpendicular to the parting plane 18 and thus a short circuit flow in the longitudinal channel 11 is largely prevented. The coolant then flows through the oil cooler 10 with two deflections, partly in its longitudinal and partly in its transverse direction, so that a good cooling effect is ensured in the latter.
