Abstract

Chemise recouvrant l'espace entre les rangées de cylindres agencées en V dans un moteur à combustion interne (1) pour envelopper de manière étanche aux gaz le tube pressurisé (5) agencé entre les rangées de cylindres ainsi que les tuyaux de gaz d'échappement (6) conduisant les gaz combustibles des cylindres (4) au tube pressurisé (5). Une telle chemise comporte des surfaces d'étanchéification aussi bient pour le carter-moteur (7) que pour les têtes de cylindre (10). A cause des inévitables tolérances de fabrication et tolérances de position qui en résultent, à cause aussi des importantes distorsions dues à la chaleur du moteur à combustion interne (1) lorsqu'il tourne, et du fait qu'il faut recourir à des éléments d'étanchéification résistants aux températures élevées et à faibles coefficients de dilatation, il est difficile de rendre l'espace étanche aux gaz au moyen d'une chemise unique qui porte toutes les surfaces d'étanchéification. La chemise selon la présente invention comporte donc une partie centrale (2) qui est fixée au carter-moteur (7) et ne comporte de surface de contact qu'avec ledit carter-moteur (7), et non avec les têtes de cylindre (10). D'autres parties (3) cunéiformes de chemise, qui ont de préférence la forme de tubes coudés, sont agencées dans une découpure en V, entre la partie centrale (2) de la chemise et les têtes de cylindre (10), et sont tirées dans ladite découpe en V par des vis d'extension. Elles comportent des surfaces d'étanchéification communes avec les têtes de cylindre (10) et avec la partie centrale (2) de la chemise. Les tolérances de position sont compensées par une position correspondante prise par les parties (3) de chemise cunéiformes. En conséquence, les forces requises pour presser les unes contre les autres les surfaces d'étanchéification ne dépendent que de la distorsion thermique prévue. De même, les forces induites dans la structure du moteur sont peu élevées.Jacket covering the space between the rows of cylinders arranged in a V-shape in an internal combustion engine (1) for sealingly enveloping the pressurized tube (5) arranged between the rows of cylinders as well as the exhaust gas pipes (6) leading the fuel gases from the cylinders (4) to the pressurized tube (5). Such a jacket has sealing surfaces for the crankcase (7) as well as for the cylinder heads (10). Because of the inevitable manufacturing tolerances and resulting positional tolerances, also because of the significant heat distortions of the internal combustion engine (1) when it is running, and the fact that special elements must be used. High temperature resistant seals and low expansion coefficients, it is difficult to make the space gas-tight by means of a single jacket which carries all sealing surfaces. The sleeve according to the present invention therefore comprises a central part (2) which is fixed to the crankcase (7) and only has a contact surface with said crankcase (7), and not with the cylinder heads ( 10). Other wedge-shaped liner parts (3), which are preferably in the form of bent tubes, are arranged in a V-shaped cutout, between the central liner part (2) and the cylinder heads (10), and are pulled into said V-shaped cutout by extension screws. They have common sealing surfaces with the cylinder heads (10) and with the central part (2) of the liner. Position tolerances are compensated by a corresponding position taken by the wedge-shaped liner parts (3). As a result, the forces required to press the sealing surfaces together depend only on the expected thermal distortion. Likewise, the forces induced in the engine structure are low.

Description

Den Raum zwischen V-förmig angeordneten Zylinderreihen einer Brennkraftmaschine überdeckende HaubeHood covering the space between the V-shaped rows of cylinders of an internal combustion engine
B e s c h r e i b u n gDescription
Die Erfindung betrifft eine den Raum zwischen V-förmig angeordneten Zylinderreihen einer Brennkraftmaschine überdeckende Haube nach dem Oberbegriff des Anspruchs 1, wie sie beispielsweise aus der DE-PS 36 35 478 als bekannt hervorgeht.The invention relates to a hood covering the space between V-shaped rows of cylinders of an internal combustion engine according to the preamble of claim 1, as is known for example from DE-PS 36 35 478.
In der DE-PS 36 35 478 ist die Ausbildung eines Gehäuses dargestellt, das das Staurohr einer Brennkraftmaschine und die Brenngase von den Zylinderköpfen zum Staurohr überleitende Abgasleitungen gasdicht einschließt. Das gekühlte Gehäuse befindet sich im Raum zwischen den Zylinderreihen der Brennkraftmaschine, die V-förmig angeordnet sind. Das Gehäuse besteht aus einem Unterteil und einem Oberteil, von denen letzteres Anlageflächen sowohl an den Zylinderköpfen als auch am Kurbelgehäuse besitzt. Zum gasdichten Einschluß des Staurohrs und der zum Staurohr führenden Abgasleitungen müssen, wie jedoch nicht dargestellt, die Anlageflächen an den Zylinderköpfen durch Ringdichtungen zwischen den Zylinderköpfen und dem Gehäuseoberteil abgedichtet, und ferner das Gehäuseoberteil mit einem Deckel versehen werden. Ferner mu/3 eine dichte Anlage des Gehäuseoberteils am Gehäuseunterteil oder, wenn der abgasdichte Raum anstelle von einem Gehäuseunterteil durch die Wandungen des Kurbelgehäuses begrenzt ist, des Gehäuseoberteils am Kurbelgehäuse vorgesehen sein. Wegen der auftretenden hohen Temperaturen sind in den Dichtbereichen hochtemperaturfeste Graphitdichtungen erforderlich, die jedoch den Nachteil eines geringen Dehnungsvermögens besitzen. Da das Gehäuseoberteil zum einen am Kurbelgehäuse aufliegt und zum anderen zugleich Dichtflächen mit den Zylinderköpfen bildet, und hochtemperaturfeste Dichtungen mit nur geringer Dehnungsfähigkeit verwendet werden sollten, müssen möglichst enge Fertigungstoleranzen gesetzt werden, um möglichst kleine Lagetoleranzen zu erreichen, was allerdings zu hohen Fertigungskosten führt. Wegen der dennoch unvermeidlichen Toleranzen und der im Betrieb der Brennkraftmaschine auftretenden starken Wärmeverzüge müssen hohe Vorspannungen im Bereich der Dichtflächen wirken, um Undichtwerden zu vermeiden. Hohe Vorspannungen bedingen jedoch wiederum hohe Schraubkräfte, die in das Kurbelgehäuse und die Zylinderköpfe eingeleitet werden und unter Umständen zu unerwünschten Verformungen der Zylinderlaufbüchsen oder anderer Teile der Brennkraftmaschine führen.In DE-PS 36 35 478 the formation of a housing is shown which gas-tight encloses the pitot tube of an internal combustion engine and the fuel gases from the cylinder heads to the pitot tube. The cooled housing is located in the space between the rows of cylinders of the internal combustion engine, which are arranged in a V-shape. The housing consists of a lower part and an upper part, the latter of which has contact surfaces both on the cylinder heads and on the crankcase. For the gas-tight inclusion of the pitot tube and the exhaust pipes leading to the pitot tube, however, the contact surfaces on the cylinder heads must be sealed by ring seals between the cylinder heads and the upper housing part, and furthermore the upper part of the housing must be provided with a cover, but not shown. Furthermore, a tight contact of the upper housing part on the lower housing part or, if the gas-tight space is limited instead of a lower housing part by the walls of the crankcase, the upper housing part on the crankcase must be provided. Because of the high temperatures that occur, high-temperature-resistant graphite seals are required in the sealing areas, but these have the disadvantage of low expansion capacity. Since the upper part of the housing rests on the one hand on the crankcase and on the other hand forms sealing surfaces with the cylinder heads, and high-temperature-resistant seals with only a small amount Elasticity should be used, the tightest possible manufacturing tolerances must be set in order to achieve the smallest possible tolerances, but this leads to high manufacturing costs. Because of the inevitable tolerances and the strong heat distortions that occur during operation of the internal combustion engine, high preloads must act in the area of the sealing surfaces in order to avoid leakage. However, high preloads in turn cause high screwing forces, which are introduced into the crankcase and the cylinder heads and, under certain circumstances, can lead to undesired deformations of the cylinder liners or other parts of the internal combustion engine.
Der Erfindung liegt die Aufgabe zugrunde, die Abdichtung eines von einer Haube überdeckten Raumes zwischen zwei Zylinderreihen eines V-Motors sicherzustellen, ohne da/3 besondere Anforderungen an die Fertigungstoleranzen zu stellen, oder ein besonders hohes Dehnvermögen der Dichtungen zu verlangen sind, und zur Erzielung einer guten Abdichtung dennoch keine hohen Kräfte in ungünstigen Bereichen des Motors eingeleitet werden müssen.The invention is based on the object to seal a covered by a hood space between two rows of cylinders of a V-type engine ensure without da / to provide 3 special demands on the manufacturing tolerances, or an especially high elongation capability of the seals are to demand and to achieve a good seal, no high forces have to be introduced in unfavorable areas of the engine.
Diese Aufgabe wird bei einer gattungsgemäßen Ausbildung durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Durch die Ausbildung der Haube mit einem zentralen Haubenteil, das nur am Kurbelgehäuse und nicht an den Zylinderköpfen anliegt, und keilförmigen Haubenteilen, die in V-förmigen Ausschnitten zwischen dem zentralen Gehäuseteil und den Zylinderköpfen eingesetzt sind, sind die verschiedenen Dichtflächen separaten Bauteilen zugeordnet, die unabhängig voneinander befestigt werden und gegeneinander verschieblich sind. Durch die separate Befestigung in Verbindung mit der besonderen Ausbildung der Haubenteile sind die Anpreßkräfte und damit die Dichtwirkung unabhängig von den aufgrund von Fertigungstoleranzen entstehenden Lagetoleranzen. Es können deshalb von vomeherein geringere Vorspannungen im Bereich der Dichtflächen vorgesehen werden, wodurch auch die Beanspruchung der Motorbauteile durch einzuleitende Kräfte sinkt. Ein Ausführungsbeispiel der Erfindung ist in einer Zeichnung dargestellt und wird im folgenden näher beschrieben; es zeigt die einzige Figur einen Querschnitt durch eine Brennkraftmaschine im Bereich des Staurohrs.This object is achieved in a generic training by the characterizing features of claim 1. Due to the design of the hood with a central hood part, which rests only on the crankcase and not on the cylinder heads, and wedge-shaped hood parts, which are inserted in V-shaped cutouts between the central housing part and the cylinder heads, the different sealing surfaces are assigned to separate components that can be attached independently of one another and can be moved against each other. Due to the separate fastening in connection with the special design of the hood parts, the contact pressure and thus the sealing effect are independent of the positional tolerances that arise due to manufacturing tolerances. It is therefore possible from the start to provide lower preloads in the area of the sealing surfaces, as a result of which the stress on the engine components due to forces to be introduced is also reduced. An embodiment of the invention is shown in a drawing and will be described in more detail below; the only figure shows a cross section through an internal combustion engine in the region of the pitot tube.
Bei der in der Figur im Querschnitt dargestellten Brennkraftmaschine 1 mit V-förmig angeordneten Zylinderreihen ist das Staurohr 5 ebenso wie die die Brenngase von den Zylindern 4 zum Staurohr 5 überführenden Abgasleitungen 6 in einem abgasdichten Raum im Bereich zwischen den Zylinderreihen angeordnet. Der abgasdichte Raum wird durch entsprechende Wandungen des Kurbelgehäuses 7 und eine das Kurbelgehäuse 7 überdeckende Haube gebildet. Die den Raum überdeckende Haube wird aus einem zentralen Haubenteil 2, das auf dem Kurbelgehäuse 7 aufliegt, und keilförmigen Haubenteilen 3 gebildet, die als Rohrkrümmer ausgebildet sind und die Zylinderköpfe 10 mit dem zentralen Haubenteil 2 verbinden. Die Endflächen der Haubenteile 3 liegen dichtend am zentralen Haubenteil 2 und an den Zylinderköpfen 10 an. In den Anlageflächen sind jeweils Ringdichtungen 8 und 9 zum Ausgleich von Formtoleranzen angeordnet. Auf eine der Ringdichtungen kann dabei auch verzichtet werden. Die Haubenteile 3 sind mit jeweils zwei Schrauben 11 mit hohem Dehnvermögen, beispielsweise Dehnschrauben, am Kurbelgehäuse 7 angeschraubt.In the internal combustion engine 1 shown in cross section in the figure with rows of cylinders arranged in a V-shape, the pitot tube 5, like the exhaust gas lines 6 transferring the fuel gases from the cylinders 4 to the pitot tube 5, is arranged in an exhaust gas-tight space in the area between the rows of cylinders. The exhaust gas-tight space is formed by corresponding walls of the crankcase 7 and a hood covering the crankcase 7. The hood covering the space is formed from a central hood part 2, which rests on the crankcase 7, and wedge-shaped hood parts 3, which are designed as pipe elbows and connect the cylinder heads 10 to the central hood part 2. The end faces of the hood parts 3 lie sealingly on the central hood part 2 and on the cylinder heads 10. Ring seals 8 and 9 are arranged in the contact surfaces to compensate for shape tolerances. One of the ring seals can also be dispensed with. The hood parts 3 are screwed to the crankcase 7 with two screws 11 each with high expansion capacity, for example expansion screws.
Aufgrund ihrer keilförmigen Ausbildung und ihrer Verschiebbarkeit gegenüber dem zentralen Haubenteil 2 können die Haubenteile 3 Lagetoleranzen und Wärmeverzug durch Änderung ihrer Höhenlage ausgleichen. Die Dichtwirkung ist unabhängig von den Lagetoleranzen. Die Kräfte, mit der die Dichtflächen der keilförmigen Haubenteile 3 in ihrer Anlage am zentralen Haubenteil 2 und an den Zylinderköpfen 10 angepreßt werden, hängen somit alleine von dem erwarteten Wärmeverzug der Brennkraftmaschine ab, und nicht von Lagetoleranzen. Dementsprechend niedrig sind die von Schrauben 11 in die Motorstruktur eingeleiteten Kräfte. Da der Wärmeverzug des Motors von den Schrauben 11 unter Verlagerung der keilförmigen Haubenteile 3 aufgenommen wird, können Dichtelemente mit geringem Dehnungsvermögen, beispielsweise Graphitdichtungen, eingesetzt werden, die hochtemperaturbeständig sind.Because of their wedge-shaped design and their displaceability relative to the central hood part 2, the hood parts 3 can compensate for positional tolerances and heat distortion by changing their height. The sealing effect is independent of the position tolerances. The forces with which the sealing surfaces of the wedge-shaped hood parts 3 are pressed against the central hood part 2 and the cylinder heads 10 thus depend solely on the expected heat distortion of the internal combustion engine and not on positional tolerances. The forces introduced by screws 11 into the motor structure are correspondingly low. Because the heat delay of the Motors is taken up by the screws 11 with displacement of the wedge-shaped hood parts 3, sealing elements with low expansion capacity, for example graphite seals, can be used which are resistant to high temperatures.
Der Ausgleich von Formtoleranzen am zentralen Haubenteil 2 kann durch eine Dichtung 12 in der Auflage am Kurbelgehäuse 7 erfolgen. Lagetoleranzen haben keinen Einfluß auf die Abdichtung.Die am zentralen Haubenteil 2 aufliegenden Haubenteile 3 erhöhen zusätzlich die Anpreßkraft des Haubenteils 2 auf das Kurbelgehäuse 7. Die Dichtwirkung zwischen Kurbelgehäuse 7 und Haubenteil 2 wird dadurch erhöht. Die von den Haubenteilen 3 am zentralen Haubenteil 2 ausgeübte Kraft kann bei der Auslegung der Anzahl der Befestigungsschrauben für das zentrale Haubenteil 2 berücksichtigt werden.The compensation of shape tolerances on the central hood part 2 can take place by a seal 12 in the support on the crankcase 7. Positional tolerances have no influence on the seal. The hood parts 3 resting on the central hood part 2 additionally increase the contact pressure of the hood part 2 on the crankcase 7. The sealing effect between the crankcase 7 and the hood part 2 is thereby increased. The force exerted by the hood parts 3 on the central hood part 2 can be taken into account when designing the number of fastening screws for the central hood part 2.
Weiter ist vorteilhaft, daß in die Zylinderköpfe aufgrund der Befestigung der Haubenteile 3 mit Schrauben 11 im Kurbelgehäuse 7 nur Querkräfte eingeleitet werden. Da sich die Anpreßkräfte in Grenzen halten und über die Anlageflächen verteilt eingeleitet werden, ist die Gefahr einer unerwünschten Verformung insbesondere im Bereich der Laufbüchsen ausgeschlossen. It is also advantageous that only lateral forces are introduced into the cylinder heads due to the fastening of the hood parts 3 with screws 11 in the crankcase 7. Since the contact forces are limited and are distributed over the contact surfaces, there is no risk of undesired deformation, particularly in the area of the liners.
