Abstract

A channel for distributing lubricating oil is arranged in the crankcase (13) of an internal combustion engine and extends through transverse walls (11, 12). The sections of the channel between two transverse walls (11, 12) consist of a plug-in tube (23) and a socket tube (24), which can be mutually displaced and rigidly coupled in the axial direction. The free ends of the plug-in tube (23) and the socket tube (24) are sealingly guided in the drilled passages (14, 15) in the transverse walls of the canal. This arrangement permits simplified machining of the crankcase (13) in the region of the channel.

Description

Die Erfindung bezieht sich auf einen Kanal für die Verteilung von Schmieröl in einer Kolbenbrennkraftmaschine gemäß dem Oberbegriff von Anspruch 1. Das in Filter und Ölkühler konditionierte Schmieröl wird über den Kanal und durch in den Querwänden verlaufende Abzweigbohrungen verschiedenen Verbrauchsstellen zugeführt.The invention relates to a channel for the distribution of lubricating oil in a piston internal combustion engine according to the preamble of claim 1. The lubricating oil conditioned in the filter and oil cooler is supplied to various consumption points via the channel and through branch bores running in the transverse walls.

Es ist bekannt (siche die JP-A-5960017), die Kanalabschnitte im Bereich zwischen zwei Querwänden des Kurbelgehäuses aus mehreren kanalbildenden Bauteilen zusammenzusetzen. Jeder Kanalabschnitt umfaßt zwei flanschartige, durch Schrauben befestigte Anschlußteile mit je einer Muffe und ein in die Muffen der beiden zugehörigen Anschlußteile dichtend einsteckbares Rohr. Um die Mündungen der Querwanddurchgänge des Kanals herum sind Dichtflächen für die Anschlußteile ausgebildet.It is known (see JP-A-5960017) to assemble the duct sections in the region between two transverse walls of the crankcase from a plurality of duct-forming components. Each channel section comprises two flange-like connecting parts fastened by screws, each with a sleeve and a tube which can be inserted sealingly into the sleeves of the two associated connecting parts. Sealing surfaces for the connection parts are formed around the mouths of the transverse wall passages of the channel.

Die Bearbeitung der Dichtflächen für die Anschlußteile an den Querwänden des Kurbelgehäuses, sowie die Herstellung der Bohrungen für die Schraubenbefestigung der Anschlußteile sind aufgrund der schlechten Zugänglichkeit der Bearbeitungsstellen im Kurbelgehäuse schwierige und kostenintensive Arbeitsvorgänge.The processing of the sealing surfaces for the connecting parts on the transverse walls of the crankcase, as well as the production of the holes for the screw fastening of the connecting parts are difficult and cost-intensive work processes due to the poor accessibility of the machining points in the crankcase.

Es ist deshalb Aufgabe der Erfindung, durch die Ausbildung der Bauteile für die Kanalabschnitte zwischen den Querwänden, eine vereinfachte Bearbeitung des Kurbelgehäuses im Bereich des Kanals zu erreichen.It is therefore an object of the invention to achieve a simplified machining of the crankcase in the region of the channel by the design of the components for the channel sections between the transverse walls.

Diese Aufgabe ist erfindungsgemäß mit den kennzeichnenden Merkmalen von Patentanspruch 1 gelöst.This object is achieved with the characterizing features of claim 1.

Die weitere Ausgestaltung der Erfindung ergibt sich aus den Merkmalen der Ansprüche 2 bis 5.The further embodiment of the invention results from the features of claims 2 to 5.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß sich eine Senkung der Herstellungskosten des Kurbelgehäuses ergibt, daß Gewicht und Anzahl der Bauteile eines zwischen zwei Querwänden zu montierenden Kanalabschnittes reduziert sind, daß sich niedrige Herstellungskosten für Muffen- und Steckrohr ergeben und daß Montage und Demontage der Bauteile des Kanalabschnittes schnell und einfach durchzuführen ist.The advantages achieved by the invention are, in particular, that there is a reduction in the manufacturing costs of the crankcase, that the weight and number of components of a duct section to be mounted between two transverse walls are reduced, that there are low manufacturing costs for socket and plug-in pipe, and that assembly and Disassembly of the components of the channel section can be carried out quickly and easily.

Ein der Verteilung von Schmieröl dienender Kanal erstreckt sich in Längsrichtung einer Kolbenbrennkraftmaschine durch mehrere Querwände 11, 12 des nur teilweise dargestellten Kurbelgehäuses 13 hindurch. Die Querwanddurchgänge 14, 15 des Kanals sind als Bohrungen ausgeführt, von denen Abzweigbohrungen 16, 17 abgehen, die das Schmieröl verschiedenen Verbrauchsstellen, z. B. den Kurbelwellenlagern 18, 19 zuführen. Zwischen den Querwänden 11, 12 wird der Kanal aus zwei axial aneinandergefügten Bauteilen gebildet, die untereinander und gegenüber den Querwanddurchgängen 14, 15 abgedichtet sind.A channel serving to distribute lubricating oil extends in the longitudinal direction of a piston internal combustion engine through a plurality of transverse walls 11, 12 of the crankcase 13, which is only partially shown. The transverse wall passages 14, 15 of the channel are designed as bores, from which branch holes 16, 17 depart, which the lubricating oil different consumption points, for. B. the crankshaft bearings 18, 19. Between the transverse walls 11, 12, the channel is formed from two axially joined components, which are sealed to one another and to the transverse wall passages 14, 15.

Die zwischen den Querwänden 11, 12 eingesetzten kanalbildenden Bauteile bestehen aus einem Steckrohr 23 und einem das Steckrohr 23 in einer Muffe 25 aufnehmenden Muffenrohr 24, die im Einbauzustand gegeneinander axial verschiebbar sind. Die Mündung der Muffe 25 ist als einseitig radial geschlitzte Klemmschelle 26 mit einer Schraube als Spanneinrichtung 27 ausgebildet. An den freien Enden von Steckrohr 23 und Muffenrohr 24 sowie an dem in der Muffe 25 steckenden Ende des Steckrohres 23 ist am Außenumfang je eine radiale Nut zur Aufnahme eines Dichtringes 20, 21, 22 angeordnet. Vorteilhafterweise haben die drei radialen Nuten die gleichen Abmessungen, so daß nur eine einzige Dichtringgröße erforderlich ist.The channel-forming components used between the transverse walls 11, 12 consist of a plug-in tube 23 and a socket tube 24 which receives the plug-in tube 23 in a sleeve 25 and which can be axially displaced relative to one another in the installed state. The mouth of the sleeve 25 is designed as a radially slotted clamp 26 with a screw as a clamping device 27. A radial groove for receiving a sealing ring 20, 21, 22 is arranged on the outer circumference of the free ends of the plug-in pipe 23 and the socket pipe 24 as well as on the end of the plug-in pipe 23 inserted in the socket 25. The three radial grooves advantageously have the same dimensions, so that only a single size of the sealing ring is required.

Die Wand 28 der Muffe 25 ist axial benachbart zu der an der Mündung der Muffe 25 befindlichen Klemmschelle 26 mit zwei einander diametral gegenüberliegenden Durchbrechungen 29, 30 ausgestattet. Ferner sind im Mittelteil des Steckrohres 23 am Außenumfang zwei benachbarte Umfangsnuten 31, 32 ausgebildet, die sich in axialer Zuordnung zu den Durchbrechungen 29, 30 in der Wand 28 der Muffe 25 und zu der Spanneinrichtung 27 der Klemmschelle 26 befinden.The wall 28 of the sleeve 25 is axially adjacent to the clamp 26 located at the mouth of the sleeve 25 with two diametrically opposite openings 29, 30. Furthermore, two adjacent circumferential grooves 31, 32 are formed on the outer circumference in the middle part of the plug-in tube 23, which are located axially in relation to the openings 29, 30 in the wall 28 of the sleeve 25 and to the tensioning device 27 of the clamp 26.

Beim Einbau ist das Steckrohr 23 bis zum Anschlag am Grund 37 der Muffe 25 in das Muffenrohr 24 eingeschoben. Dadurch wird die Baulänge der ineinander gefügten Teile so weit verkürzt, daß sie mit axialem Spiel zwischen die Querwände 11, 12 eingeführt werden können (siehe Fig. 1a). Sobald sich Steckrohr 23 und Muffenrohr 24 in fluchtender Position mit den gebohrten Querwanddurchgängen 14, 15 befinden, wird mit Hilfe eines Werkzeugs, das sich durch die Durchbrechungen 29, 30 hindurch in der sichtbaren Umfangsnut 32 und an der Stirnseite der Klemmschelle 26 abstützt, das Steckrohr 23 aus der Muffe 25 hinausgeschoben. Die freien Enden von Steckrohr 23 und Muffenrohr 24 mit den montierten Dichtringen 20, 22 werden dabei in die gebohrten Querwanddurchgänge 14, 15 des Kanals hineingedrückt. Um das Einführen der Dichtringe 20, 22 in die Querwanddurchgänge 14, 15 zu erleichtern, sind deren Mündungen beiderseits mit einer kegeligen Erweiterung 33 ausgebildet.During installation, the plug-in tube 23 is pushed into the sleeve tube 24 up to the stop on the base 37 of the sleeve 25. As a result, the overall length of the parts joined into one another is shortened to such an extent that they can be inserted with axial play between the transverse walls 11, 12 (see FIG. 1a). As soon as the plug-in pipe 23 and the socket pipe 24 are in the aligned position with the drilled transverse wall passages 14, 15, the plug-in pipe is made with the aid of a tool which is supported through the openings 29, 30 in the visible circumferential groove 32 and on the end face of the clamp clip 26 23 pushed out of the sleeve 25. The free ends of plug-in pipe 23 and socket pipe 24 with the assembled sealing rings 20, 22 are pressed into the drilled transverse wall passages 14, 15 of the channel. To insert the sealing rings 20, 22 in the To facilitate transverse wall passages 14, 15, the mouths are formed on both sides with a conical extension 33.

Nach dem ersten Schiebehub des Steckrohres 23 erreicht die Umfangsnut 32 den Rand der Durchbrechungen 29, 30 im Bereich der Klemmschelle 26. Das Werkzeug wird dann umgesetzt, so daß es sich nun in der zweiten benachbarten Umfangsnut 31, die in den Durchbrechungen 29, 30 zugänglich geworden ist, abstützt. Der zweite Schiebehub des Steckrohres 23 ist beendet, wenn die an den freien Enden von Steck- und Muffenrohr 23, 24 ausgebildeten kegeligen Schultern 34 den kegeligen Erweiterungen 33 der Querwanddurchgänge 14, 15 mit geringem Abstand gegenüberstehen. In dieser Stellung von Steckrohr 23 und Muffenrohr 24 läßt sich die Schraube in die Klemmschelle 26 einschrauben und festziehen. Die Klemmschelle 26 wird dadurch auf dem Steckrohr 23 festgeklemmt, so daß keine Axialverschiebbarkeit zwischen Steck- und Muffenrohr 23, 24 mehr besteht. Der radiale bestand der Schraube von der Achse der Muffe 25 ist so gewählt, daß der Schraubenschaft radial in die Umfangsnut 32 eingreift (siehe Fig. 4). Dadurch wird eine zusätzliche Sicherung gegen unbeabsichtigtes Zusammenschieben von Steckrohr 23 und Muffenrohr 24 erreicht, wenn die Spannung der Klemmschelle 26 nachlassen sollte.After the first sliding stroke of the plug-in tube 23, the circumferential groove 32 reaches the edge of the openings 29, 30 in the region of the clamp 26. The tool is then moved so that it is now accessible in the second adjacent circumferential groove 31, which is in the openings 29, 30 has become supported. The second sliding stroke of the plug-in pipe 23 is ended when the conical shoulders 34 formed on the free ends of the plug-in and socket pipe 23, 24 face the conical extensions 33 of the transverse wall passages 14, 15 with a small distance. In this position of the plug-in tube 23 and the socket tube 24, the screw can be screwed into the clamp 26 and tightened. The clamp 26 is thereby clamped on the plug pipe 23, so that there is no longer any axial displacement between the plug and socket pipe 23, 24. The radial consist of the screw from the axis of the sleeve 25 is selected so that the screw shaft engages radially in the circumferential groove 32 (see Fig. 4). This provides additional protection against inadvertent pushing together of the plug-in tube 23 and the socket tube 24 if the tension of the clamp 26 should decrease.

Die kegeligen Schultern 34 an Steck- und Muffenrohr 23, 24 haben im montierten Zustand gegenüber den kegeligen Erweiterungen 33 der Querwanddurchgänge 14, 15 einen geringen axialen Abstand, der unterschiedliche Wärmedehnungen zwischen Kurbelgehäuse 13 und den kanalbildenden Bauteilen auffängt. Die kegeligen Schultern 34 wirken außerdem als axiale Begrenzung für das, sich im Betrieb der Kolbenbrennkraftmaschine ergebende, Hin- und Herwandern der miteinander verspannten, kanalbildenden Bauteile.The tapered shoulders 34 on the plug and socket pipe 23, 24 have a small axial distance in the assembled state compared to the tapered extensions 33 of the transverse wall passages 14, 15, which absorbs different thermal expansions between the crankcase 13 and the channel-forming components. The tapered shoulders 34 also act as an axial limitation for the back and forth movement of the clamped channel-forming components, which results during the operation of the piston internal combustion engine.

Am Außenumfang des Muffenrohres 24 sind zwei radial abstehende Nocken 35 ausgebildet. Im Einbauzustand verhindern die Nocken 35 durch Anlage an der Kontur 36 des Kurbelgehäuses 13 das Drehen von Steckrohr 23 und Muffenrohr 24 um ihre gemeinsame Längsachse. Dadurch bleibt die Zugänglichkeit der Spanneinrichtung 27 der Klemmschelle 26 und der Durchbrechungen 29, 30 in Einbaulage erhalten, was eine später erforderliche Demontage erleichtert.Two radially projecting cams 35 are formed on the outer circumference of the socket pipe 24. In the installed state, the cams 35 prevent rotation by contacting the contour 36 of the crankcase 13 of plug pipe 23 and sleeve pipe 24 about their common longitudinal axis. As a result, the accessibility of the tensioning device 27 of the clamp 26 and the openings 29, 30 is retained in the installed position, which facilitates disassembly that is required later.
