Abstract

Das Zylinderkurbelgehäuse (1) für eine mehrzylindrige Brennkraftmaschine besteht aus einer Leichtmetalllegierung und weist zwischen den Zylindern (2,3) Trennwände auf. Die Zylinder (2,3) sind von Kühlwasserkanälen (8,9) umgeben. Oberhalb des Zylinderkurbelgehäuses (1) ist ein Zylinderkopf (11) vorgesehen, wobei zwischen Zylinderkurbelgehäuse (1) und Zylinderkopf (11) im Bereich der Zylinder Brennräume liegen. Um beim Betrieb der Brennkraftmaschine (1) sicherzustellen, daß die Zylinderdurchmesser benachbart den Brennräumen, namentlich im Bereich der Trennwände (10), innerhalb festgelegter Toleranzen gehalten werden, sind in den Trennwänden (13) Wärmedehnungsschlitze (14) vorgesehen, die in die Kühlwasserkanäle (8,9) münden. Diese Wärmedehnungsschlitze sind gegenüber den Kühlwasserkanälen (8,9) abgedichtet, damit die Trennwände (10) nicht durch Kavitation beeinträchtigt werden.The cylinder crankcase (1) for a multi-cylinder internal combustion engine consists of a light metal alloy and has partitions between the cylinders (2, 3). The cylinders (2,3) are surrounded by cooling water channels (8,9). A cylinder head (11) is provided above the cylinder crankcase (1), combustion chambers being located between the cylinder crankcase (1) and the cylinder head (11) in the region of the cylinders. In order to ensure during operation of the internal combustion engine (1) that the cylinder diameters adjacent to the combustion chambers, especially in the area of the partition walls (10), are kept within defined tolerances, thermal expansion slots (14) are provided in the partition walls (13), which extend into the cooling water channels ( 8.9). These thermal expansion slots are sealed off from the cooling water channels (8, 9) so that the partitions (10) are not affected by cavitation.

Description

Die Erfindung betrifft ein Zylinderkurbelgehäuse nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a cylinder crankcase according to the preamble of patent claim 1.

Es ist bekannt (DE-PS 29 11 628), einzelne Leichtmetallzylinder, die luftgekühlt sind, im an den Zylinderkopf angrenzenden Bereich mit Wärmedehnungseinrichtungen zu versehen, die den dort auftretenden Verwerfungen und Ausbuchtungen entgegenwirken.It is known (DE-PS 29 11 628) to provide individual light metal cylinders, which are air-cooled, in the area adjacent to the cylinder head with thermal expansion devices which counteract the distortions and bulges that occur there.

Aufgabe der Erfindung ist es, an einem mehrere Zylinder umfassenden, mit Kühlwasserkanälen ausgestatteten Zylinderkurbelgehäuse aus einer Leichtmetalllegierung gezielte Wärmedehnungsmaßnahmen zu verwirklichen. Dabei sollte aber sichergestellt sein, daß trotz dieser Maßnahmen die Standfestigkeit des Zylinderkurbelgehäuses erhalten bleibt.The object of the invention is to implement targeted thermal expansion measures on a cylinder crankcase comprising a plurality of cylinders and equipped with cooling water channels and made of a light metal alloy. It should be ensured, however, that the stability of the cylinder crankcase is maintained despite these measures.

Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen enthalten.According to the invention, this object is achieved by the characterizing features of patent claim 1. Further features embodying the invention are contained in the subclaims.

Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, daß durch die Wärmedehnungsschlitze einerseits die im Betrieb der Brennkraftmaschine am Zylinderkurbelgehäuse - es besteht ja aus einer Leichtmetalllegierung - auftretenden Temperaturtoleranzen ausgeglichen werden und andererseits mechanischer Verschleiß, beispielsweise durch Eintritt von Kühlwasser in die Wärmedehnungsschlitze hervorgerufene Kavitation, aufgrund der elastischen Dichtmittel zwischen den Kühlkanälen und den Wärmedehnungsschlitzen entgegengewirkt ist. Dies kann auf einfache Weise durch die Dichtkörper oder den die Wärmedehnungsschlitze ausfüllenden polsterartigen Kunststoff erreicht werden.The main advantages achieved with the invention are that the thermal expansion slots compensate for the temperature tolerances occurring during operation of the internal combustion engine on the cylinder crankcase - it consists of a light metal alloy - and mechanical wear, for example caused by the entry of cooling water into the thermal expansion slots Cavitation, due to the elastic sealant between the cooling channels and the thermal expansion slots is counteracted. This can be achieved in a simple manner by means of the sealing body or the cushion-like plastic filling the thermal expansion slots.

In der Zeichnung werden Ausführungsbeispiele der Erfindung gezeigt, die nachstehend näher beschrieben sind.In the drawing, exemplary embodiments of the invention are shown, which are described in more detail below.

Das Zylinderkurbelgehäuse 1 ist Bestandteil einer nicht näher dargestellten Hubkolben-Brennkraftmaschine mit mehreren Zylindern der Reihenbauart, die im Viertakt-Verfahren arbeitet. Aus Gewichtsgründen besteht das Zylinderkurbelgehäuse 1 aus einer Leichtmetalllegierung, wobei in die einzelnen beabstandeten Zylinder 2, 3 eisenmetallische Zylinderlaufbüchsen 4, 5 eingesetzt sind. Mit 6 und 7 sind die Mittelachsen der Zylinder 2, 3 bezeichnet. Außerdem sind die Zylinder 2, 3 über einen wesentlichen Teilbereich von Kühlwasserkanälen 8, 9 umgeben.The cylinder crankcase 1 is part of a reciprocating internal combustion engine, not shown, with a plurality of cylinders of the series type, which works in the four-stroke process. For reasons of weight, the cylinder crankcase 1 is made of a light metal alloy, iron-metallic cylinder liners 4, 5 being inserted into the individual spaced cylinders 2, 3. 6 and 7 denote the central axes of the cylinders 2, 3. In addition, the cylinders 2, 3 are surrounded by cooling water channels 8, 9 over a substantial portion.

Darüber hinaus wird das Zylinderkurbelgehäuse 1 von einer Trennebene 10 begrenzt, die sich zwischen besagtem Gehäuse und einem Zylinderkopf 11 erstreckt (Fig. 4). Eine Zylinderkopfdichtung ist mit 12 bezeichnet. Beiderseits der Trennebene 10 sind Wärme abgebende Brennräume vorgesehen, durch die aufrechte Trennwände 13 zwischen den Zylindern 2, 3 - sie trennen auch die Kühlwasserkanäle 8, 9 - besonderen Temperaturbeanspruchungen unterliegen. Um sie - in Längsrichtung C-C Zylinderkurbelgehäuse gesehen - auszugleichen, d.h. um die Durchmesser D₁ und D₂ der Zylinder 2, 3 im Rahmen festgelegter Toleranzen zu halten, sind in den quer zur Längsrichtung C-C verlaufenden Trennwänden 13 Wärmedehnungsschlitze 14 vorgesehen, die von der Trennebene 10 aus mittels mechanischer Verfahren, z.B. Fräsen, Sägen oder dergleichen, eingebracht sind. Dabei genügt es, wenn die Wärmedehnungsschlitze 14 etwa zwischen 0,4 und 0,8 mm - Maß B - breit (Fig. 2) und etwa 20 mm tief - Maß C - sind (Fig. 1).In addition, the cylinder crankcase 1 is delimited by a parting plane 10, which extends between said housing and a cylinder head 11 (FIG. 4). A cylinder head gasket is designated by 12. Heat-emitting combustion chambers are provided on both sides of the parting plane 10, through the upright partitions 13 between the cylinders 2, 3 - they also separate the cooling water channels 8, 9 - are subject to particular temperature stresses. To compensate for them - seen in the longitudinal direction of the C-C cylinder crankcase, i.e. In order to keep the diameters D 1 and D 2 of the cylinders 2, 3 within the framework of defined tolerances, 13 thermal expansion slots 14 are provided in the dividing walls running transversely to the longitudinal direction C-C. Milling, sawing or the like are introduced. It is sufficient if the thermal expansion slots 14 are approximately between 0.4 and 0.8 mm - dimension B - wide (FIG. 2) and approximately 20 mm deep - dimension C - (FIG. 1).

Die Wärmedehnungsschlitze 14 münden mit ihren beiden Enden 15, 16 in die Kühlwasserkanäle 8, 9. Damit die Stege 17, 18 jeder Trennwand 10 nicht durch Kavitation während des Betriebs der Brennkraftmaschine beschädigt werden, sind die Wärmedehnungsschlitze 14 gegen Wassereintritt aus den Kühlwasserkanälen 8, 9 abgedichtet. Dies kann dadurch erfolgen, daß die Wärmedehnungsschlitze 14 mit einem polsterkörperartigen Kunststoff 19 (Fig. 2), beispielsweise Silikon, im wesentlichen ausgefüllt sind. Der Kunststoff 19 kann durch Gießen oder ein ähnliches Verfahren eingebracht werden.The thermal expansion slots 14 open with their two ends 15, 16 into the cooling water channels 8, 9. So that the webs 17, 18 of each partition 10 are not damaged by cavitation during operation of the internal combustion engine, the thermal expansion slots 14 are sealed against water ingress from the cooling water channels 8, 9. This can be done by essentially filling the thermal expansion slots 14 with a cushion-like plastic 19 (FIG. 2), for example silicone. The plastic 19 can be introduced by casting or a similar method.

Gemäß Fig. 3 sind im Bereich der Enden 16, 17 der Wärmedehnungsschlitze 14 Dichtkörper 20, 21 vorgesehen, die aus Elastomer oder Kunststoff bestehen und Kühlwassereintritt in die Wärmedehnungsschlitze 14 verhindern. Die Dichtkörper 20, 21 weisen eine kreiszylindrische Grundform auf und sind in korrespondierenden Bohrungen 22, 23 festgesetzt, die parallel zu den Mittelachsen 6, 7 der Zylinder 2, 3 verlaufen.According to FIG. 3, sealing bodies 20, 21 are provided in the region of the ends 16, 17 of the thermal expansion slots 14, which are made of elastomer or plastic and prevent cooling water from entering the thermal expansion slots 14. The sealing bodies 20, 21 have a circular cylindrical basic shape and are fixed in corresponding bores 22, 23 which run parallel to the central axes 6, 7 of the cylinders 2, 3.
