Abstract
Die Erfindung betrifft eine Brennkraftmaschine mit einer Verbindungsanordnung (1) für einen Zylinderkopf (2), mit zumindest einem an einer Flanschfläche des Zylinderkopfes (2) im Bereich zumindest einer Strömungsöffnung (3a) anschließenden luft- oder gasabführender Teil (5), insbesondere einem Abgassammler oder einem Einlasssammler, wobei der Teil (5) durch zumindest eine Zylinderkopfflansch (4) und Teileflansch (7) übergreifende Spannbrücke (10) am Zylinderkopf (2) befestigbar ist, wobei mindestens eine schräge Klemmfläche (7a) des Zylinderkopfflansches (4) und/oder des Teileflansches (7) durch die Spannbrücke (10) kraftbeaufschlagbar ist, dass die Flansche (4, 7) in ihrer Flanschebene (8) gegeneinander gepresst sind. Um den Montageaufwand zu verringern und Bauraum einzusparen, ist vorgesehen, dass diametral zur Strömungsöffnung (3a) eine erste und eine zweite Spannbrücke (10, 11) angeordnet sind, wobei die Spannbrücken (10, 11) durch Spannschrauben (12) miteinander verschraubt sind.The invention relates to an internal combustion engine with a connection arrangement (1) for a cylinder head (2), with at least one air or gas discharge part (5), in particular an exhaust manifold, adjoining a flange surface of the cylinder head (2) in the region of at least one flow opening (3a) or an intake manifold, the part (5) being attachable to the cylinder head (2) by at least one clamping bridge (10) spanning at least one cylinder head flange (4) and part flange (7), at least one oblique clamping surface (7a) of the cylinder head flange (4) and / or the part flange (7) can be acted upon by the tension bridge (10) such that the flanges (4, 7) are pressed against one another in their flange plane (8). In order to reduce the assembly effort and to save installation space, a first and a second clamping bridge (10, 11) are arranged diametrically to the flow opening (3a), the clamping bridges (10, 11) being screwed together by means of clamping screws (12).
Description
Die Erfindung betrifft eine Brennkraftmaschine mit einer Verbindungsanordnung für einen Zylinderkopf, mit zumindest einem an einer Flanschfläche des Zylinderkopfes im Bereich zumindest einer Strömungsöffnung anschließenden luft- oder gasabführender Teil, insbesondere einem Abgassammler oder einem Einlasssammler, wobei der Teil durch zumindest eine Zylinderkopfflansch und Teileflansch übergreifende Spannbrücke am Zylinderkopf befestigbar ist, wobei mindestens eine schräge Klemmfläche des Zylinderkopfflansches und/oder des Teileflansches durch die Spannbrücke kraftbeaufschlagbar ist, dass die Flansche in ihrer Flanschebene gegeneinander gepresst sind.The invention relates to an internal combustion engine having a connection arrangement for a cylinder head, with at least one subsequent to a flange of the cylinder head in the region of at least one flow opening air or gasabführender part, in particular an exhaust manifold or an intake manifold, wherein the part by at least one cylinder head flange and part flange cross-clamping bridge can be fastened to the cylinder head, wherein at least one inclined clamping surface of Zylinderkopfflansches and / or the part flange is kraftbeaufschlagbar by the clamping bridge, that the flanges are pressed against each other in their flange plane.
Üblicherweise werden Abgassammler durch Schrauben am Zylinderkopf befestigt, wobei pro Auslasskanal mehrere Schrauben vorgesehen sind. Dies schränkt aber die Konstruktionsfreiheiten stark ein, da die Schrauben auch bei eingebauter Brennkraftmaschine zugänglich sein müssen. Durch die nötigen Schraubenfreigänge und den Arbeitsraum zum Ansetzen des Werkzeuges wird der Bauraum nachteilig beeinflusst.Usually exhaust manifolds are fastened by screws to the cylinder head, wherein per screw outlet more screws are provided. However, this limits the design freedom greatly, since the screws must be accessible even when installed internal combustion engine. Due to the necessary Schraubenfreigänge and the working space for applying the tool, the space is adversely affected.
Die
Nachteilig ist, dass Gewindebohrungen am Zylinderkopf vorgesehen sein müssen, was einerseits den Herstellungsaufwand erhöht und andererseits die Gestaltungsfreiheit am Wassermantel einschränkt.The disadvantage is that threaded holes must be provided on the cylinder head, which on the one hand increases the production cost and on the other hand limits the freedom of design on the water jacket.
Weitere Klemmlösungen für die Befestigung von Abgassammlern an Zylinderköpfen sind aus den Veröffentlichungen
Es ist die Aufgabe der Erfindung diese Nachteile zu vermeiden und eine alternative Befestigungsmöglichkeit für den Abgaskrümmer bzw. Einlasssammler am Zylinderkopf zu entwickeln, mit welcher der Montageaufwand verringert und Bauraum eingespart werden kann.It is the object of the invention to avoid these disadvantages and to develop an alternative mounting option for the exhaust manifold or intake manifold on the cylinder head, with which the assembly effort can be reduced and space can be saved.
Erfindungsgemäß wird dies dadurch erreicht, dass diametral zur Strömungsöffnung eine erste und eine zweite Spannbrücke angeordnet sind, wobei die Spannbrücken durch Spannschrauben miteinander verschraubt sind.According to the invention this is achieved in that diametrically to the flow opening, a first and a second clamping bridge are arranged, wherein the clamping bridges are screwed together by clamping screws.
Die Verbindung zwischen Zylinderkopf und dem Abgas oder Luft führenden Teil erfolgt nur durch die Klemmeinrichtung, wobei am Zylinderkopf oder am Teil keine Schraube angreift. Dies ermöglicht es, den Herstellungs- und Montageaufwand zu verringern und die Zylinderkopfsammleranordnung sehr kompakt auszuführen.The connection between the cylinder head and the exhaust or air-carrying part takes place only through the clamping device, wherein the cylinder head or the part no screw attacks. This makes it possible to reduce the manufacturing and assembly costs and perform the cylinder head collector assembly very compact.
Dabei kann vorgesehen sein, dass die beiden Spannbrücken sich über mehrere in Längsrichtung des Zylinderkopfes nebeneinander angeordnete Strömungsöffnungen, vorzugsweise über mehrere Zylinder hinweg, erstrecken, wobei vorzugsweise die erste und zweite Spannbrücke im Wesentlichen parallel zueinander angeordnet sind. In einer besonders einfachen Ausführungsvariante ist vorgesehen, dass die beiden Spannbrücken baugleich ausgebildet und vorzugsweise durch V-förmige Klemmschienen gebildet sind, wobei vorzugsweise zwischen Zylinderkopfflansch und Teileflansch zumindest ein Passstift in entsprechenden Bohrungen des Zylinderkopfes und des Teiles angeordnet ist. Eine besonders sichere Verbindung zwischen dem Zylinderkopf und dem Teil ergibt sich, wenn beidseits jeder Strömungsöffnung eine die beiden Spannbrücken miteinander verbindende Spannschraube angeordnet ist.In this case, it can be provided that the two clamping bridges extend over a plurality of flow openings arranged side by side in the longitudinal direction of the cylinder head, preferably over a plurality of cylinders, wherein preferably the first and second clamping bridges are arranged substantially parallel to one another. In a particularly simple embodiment, it is provided that the two clamping bridges are of identical construction and are preferably formed by V-shaped clamping rails, wherein at least one dowel pin is preferably arranged between cylinder head flange and part flange in corresponding bores of the cylinder head and the part. A particularly secure connection between the cylinder head and the part results when a clamping screw connecting the two clamping bridges is arranged on each side of each flow opening.
Vorzugsweise ist vorgesehen, dass der ersten Spannbrücke zumindest eine erste Spannfläche des Zylinderkopfflansches und eine erste Klemmfläche des Teileflansches zugeordnet ist, und dass der zweiten Spannbrücke zumindest eine zweite Klemmfläche des Zylinderkopfflansches und/oder zumindest eine zweite Spannfläche des Teileflansches zugeordnet ist. Weiters ist es vorteilhaft, wenn gleichnamige Klemmflächen des Zylinderkopfflansches und/oder des Teileflansches in Längsrichtung des Zylinderkopfes betrachtet, fluchtend angeordnet sind. Dies ermöglicht eine besonders einfache Bearbeitung.It is preferably provided that at least a first clamping surface of the Zylinderkopfflansches and a first clamping surface of the component flange is assigned to the first clamping bridge, and that the second clamping bridge is associated with at least a second clamping surface of Zylinderkopfflansches and / or at least a second clamping surface of the part flange. Furthermore, it is advantageous if the same clamping surfaces of the cylinder head flange and / or the part flange viewed in the longitudinal direction of the cylinder head, are arranged in alignment. This allows a particularly simple processing.
Eine besonders einfache Herstellung wird ermöglicht, wenn sich die erste Spannfläche und/oder die zweite Klemmfläche des Zylinderkopfflansches und/oder des Teileflansches über mehrere Strömungsöffnungen, vorzugsweise über mehrere Zylinder hinwegerstreckt.A particularly simple production is made possible when the first clamping surface and / or the second clamping surface of the cylinder head flange and / or the part flange extends over a plurality of flow openings, preferably over a plurality of cylinders.
Um eine besonders sichere Verbindung zu erreichen, ist es vorteilhaft, wenn die ersten Klemmflächen des Zylinderkopfflansches und des Teileflansches V-förmig zueinander angeordnet sind, wobei die erste Spannbrücke mit diesen korrespondierende V-förmig angeordnete Spannflächen aufweist. Weiters kann vorgesehen sein, dass die zweiten Klemmflächen des Zylinderkopfflansches und des Teileflansches V-förmig zueinander angeordnet sind, wobei die zweite Spannbrücke mit diesen korrespondierende V-förmig angeordnete Spannflächen aufweist. In order to achieve a particularly secure connection, it is advantageous if the first clamping surfaces of the cylinder head flange and the part flange are arranged in a V-shape relative to one another, wherein the first clamping bridge has clamping surfaces which are correspondingly arranged in a V-shape. Furthermore, it can be provided that the second clamping surfaces of the cylinder head flange and the part flange are arranged in a V-shape relative to one another, wherein the second clamping bridge has clamping surfaces which are correspondingly arranged in a V-shape.
