Description
Die Erfindung betrifft einen Kolben für einen Verbrennungsmotor sowie einen Verbrennungsmotor mit einem Kolben.The invention relates to a piston for an internal combustion engine and an internal combustion engine with a piston.
Auf dem Gebiet der Verbrennungsmotoren, in denen sich Kolben in Zylindern oder Zylinderlaufbuchsen bewegen und zusammen mit weiteren Komponenten den Brennraum definieren, ist es unter bestimmten Umständen üblich, die Kolben mit beispielsweise ringförmigen Kühlkanälen zu versehen, und in diese mittels einer oder mehreren Düsen Kühlmittel, beispielsweise Kühlöl, einzuspritzen. Es versteht sich, dass es unter keinen Umständen zu einem zu geringen Freiraum zwischen der Kühlöldüse und jeglichen Teilen des Kolbens oder sogar einer Kollision zwischen diesen Bauteilen kommen darf. Dementsprechend ist es bislang erforderlich, das Kolbendesign an gegebenenfalls geänderte Positionen der Kühlöldüsen anzupassen. Dies kann wirtschaftlich deshalb besonders aufwändig sein, weil vollständige Gusswerkzeuge neu erzeugt werden müssen.In the field of internal combustion engines, in which pistons move in cylinders or cylinder liners and define together with other components the combustion chamber, it is customary in certain circumstances to provide the pistons with, for example, annular cooling channels, and into these by means of one or more nozzles coolant, For example, cooling oil to inject. It will be understood that under no circumstances may there be too little clearance between the cooling oil nozzle and any parts of the piston or even a collision between these components. Accordingly, it has hitherto been necessary to adapt the piston design to optionally changed positions of the cooling oil nozzles. This can be particularly costly because economic because complete casting tools must be recreated.
Aus der
Die
Vor dem oben genannten Hintergrund liegt der Erfindung die Aufgabe zugrunde, einen Kolben für einen Verbrennungsmotor und einen damit ausgerüsteten Verbrennungsmotor zu schaffen, bei denen eine erhöhte Flexibilität im Hinblick auf unterschiedliche Positionen von Kühlöldüsen realisiert ist.Against the background mentioned above, the object of the invention is to provide a piston for an internal combustion engine and an internal combustion engine equipped therewith, in which increased flexibility with regard to different positions of cooling oil nozzles is realized.
Die Lösung dieser Aufgabe erfolgt durch den im Anspruch 1 beschriebenen Kolben.The solution to this problem is achieved by the piston described in claim 1.
Demzufolge weist dieser an seinem in Gebrauchsstellung üblicherweise unteren, das heißt dem Kolbenboden, der den Brennraum begrenzt, gegenüberliegenden Rand zumindest eine in radialer Richtung ausgebildete Aussparung auf. Mit anderen Worten ist der durch Schaftwandabschnitte, die im Gebrauch an den Zylinderwänden anliegen, und die Verbindungswände dazwischen definierte "Innenraum" des Kolbens in radialer Richtung erweitert. Diese Erweiterung führt, wenn man den Kolben in axialer Richtung betrachtet, an der Außenseite der Verbindungswand oder -wände, in der die Aussparung üblicherweise ausgebildet ist, zu einer Ausbauchung oder Beule. Dies gilt insbesondere, wenn die Wanddicke im Bereich der Aussparung im Wesentlichen gleich ist wie benachbart hierzu. Unabhängig davon kann jedoch auch bei verringerter Wanddicke an der Innenseite die beschriebene Aussparung oder Nische ausgebildet sein, die zusätzlichen Raum für unterschiedliche Positionen von Kühlöldüsen schafft.Accordingly, this has at its in use position usually lower, that is, the piston head, which limits the combustion chamber, opposite edge on at least one recess formed in the radial direction. In other words, the "interior space" of the piston defined by shaft wall portions which abut against the cylinder walls in use and the connecting walls therebetween is widened in the radial direction. This extension, when viewed in the axial direction, results in a bulge or bulge on the outside of the connecting wall or walls in which the recess is usually formed. This is especially true if the wall thickness in the region of the recess is substantially the same as adjacent thereto. Independently of this, however, even with a reduced wall thickness on the inside, the described recess or niche can be formed, which creates additional space for different positions of cooling oil nozzles.
Dies führt zu einer Verbesserung verglichen mit einer Situation, bei der, aus welchen Gründen auch immer, die Kühlöldüse ein wenig in radialer Richtung nach außen versetzt wurde, und hierdurch die Gestaltung des Kolbens geändert werden müsste. Bei dem erfindungsgemäßen Kolben ermöglicht die beschriebene Aussparung oder Nische zusätzliche Kühlölpositionen, so dass die Verwendbarkeit des erfindungsgemäßen Kolbens verbessert, und die Wirtschaftlichkeit desselben erhöht wird. Insbesondere hat sich herausgestellt, dass vorhandene Kolbenwerkzeuge zur Ausbildung der Erfindungsgemäßen Aussparung umgebaut werden können, ohne neue Komponenten verwenden zu müssen. Eine Berechnung mittels finiter Elemente hat darüber hinaus die grundsätzliche Machbarkeit des erfindungsgemäßen Kolbens ergeben.This leads to an improvement compared to a situation where, for whatever reason, the cooling oil nozzle has been displaced slightly outward in the radial direction, and thereby the design of the piston would have to be changed. In the piston according to the invention, the described recess or niche allows additional cooling oil positions, so that the usability of the piston according to the invention is improved, and the economic efficiency thereof is increased. In particular, it has been found that existing piston tools can be rebuilt to form the recess according to the invention without having to use new components. In addition, a calculation by means of finite elements has revealed the fundamental feasibility of the piston according to the invention.
Um entsprechende Gestaltungen von Kühlöldüsen zu berücksichtigen und/oder für einen harmonischen Übergang zu dem Bereich oberhalb der beschriebenen Aussparung zu gewährleisten, ist die Aussparung mit einer Tiefe in radialer Richtung ausgebildet, die sich von dem unteren Rand ausgehend in Richtung der Kolbenachse verringert.In order to take account of corresponding designs of cooling oil nozzles and / or to ensure a harmonious transition to the region above the described recess, the recess is formed with a depth in the radial direction, which decreases starting from the lower edge in the direction of the piston axis.
Bevorzugte Weiterbildungen sind in den weiteren Ansprüchen beschrieben.Preferred developments are described in the further claims.
Um die Stabilität des Kolbens in seinem unteren Bereich nicht zu gefährden, und gleichzeitig in vorteilhafter Weise den Materialeinsatz zu begrenzen, wird bevorzugt, die Materialdicke an dem die Aussparung begrenzenden Abschnitt in etwa gleich zu den Bereichen benachbart zu der Aussparung auszuführen.In order not to jeopardize the stability of the piston in its lower portion, and at the same time to advantageously limit the use of material, it is preferred to make the material thickness at the recess defining portion approximately equal to the portions adjacent to the recess.
Ferner können Einkerbungen oder dergleichen am unteren Rand des Kolbens in vorteilhafter Weise dadurch vermieden werden, dass, wie bevorzugt wird, der untere Rand des Kolbens im Bereich der Aussparung in etwa auf dem gleichen Niveau liegt, wie benachbart hierzu.Furthermore, indentations or the like at the lower edge of the piston can advantageously be avoided in that, as is preferred, the lower edge of the piston in the region of the recess is approximately at the same level as adjacent thereto.
Für eine Tiefe der zumindest Aussparung in radialer Richtung hat sich am unteren Rand des Kolbens ein Wert von ein bis drei Millimeter als günstig erwiesen.For a depth of the at least recess in the radial direction, a value of one to three millimeters has proved favorable at the lower edge of the piston.
Bei ersten Überlegungen im Hinblick auf den praktischen Einsatz des erfindungsgemäßen Kolbens hat sich herausgestellt, dass eine Ausbildung der beschriebenen Aussparung auf der Gegendruckseite des Kolbens bevorzugt wird.In the first considerations with regard to the practical use of the piston according to the invention has been found that a formation of the described recess on the counter-pressure side of the piston is preferred.
Die Erfindung beschreibt ferner einen Verbrennungsmotor, der neben dem vorangehend beschriebenen Kolben zumindest eine Kühlöldüse aufweist. Für den Abstand zwischen der Kühlöldüse und der beschriebenen Aussparung wird derzeit, um den Betriebsbedingungen und bestimmten Toleranzen Rechnung zu tragen, ein Wert von zwei Millimeter oder mehr bevorzugt.The invention further describes an internal combustion engine, which has at least one cooling oil nozzle in addition to the previously described piston. For the distance between the cooling oil nozzle and the recess described, a value of two millimeters or more is currently preferred, to take into account the operating conditions and certain tolerances.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung unter Bezugnahme auf die Zeichnung näher erläutert.An embodiment of the invention will be explained in more detail with reference to the drawing.
Die Figur zeigt eine perspektivische Unteransicht des erfindungsgemäßen Kolbens.The figure shows a perspective bottom view of the piston according to the invention.
Die Figur zeigt einen erfindungsgemäßen Kolben 10 von seiner dem Kolbenboden 12 entgegengesetzten Unterseite her. Der untere Rand des Kolbens 10 wird hier durch den jeweiligen unteren Rand von Schaftwandabschnitten 14 und Verbindungswänden 16 zwischen den Schaftwandabschnitten 14 gebildet. Wie in der Figur zu erkennen ist, ist im Bereich einer Verbindungswand, neben einer Kolbenbolzenbohrung 18 eine in radialer Richtung ausgebildete Aussparung 20 vorhanden. Mit anderen Worten ist bei dem gezeigten Beispiel die Verbindungswand 16 bei weitgehend gleichbleibender Wandstärke und/oder einem in axialer Richtung auf weitgehend gleichbleibendem Niveau befindlichen Rand in radialer Richtung etwas ausgebaucht, so dass an der Innenseite, das heißt zu der gegenüberliegenden Verbindungswand 16 hin, eine Aussparung oder Nische entsteht. In dieser Aussparung oder Nische kann auch bei veränderter Position eine Kühlöldüse aufgenommen werden, so dass sich die Einsatzmöglichkeit des erfindungsgemäßen Kolbens in wirtschaftlich günstiger Art und Weise verbessert.The figure shows a
