Description
Die Erfindung betrifft einen Kraftstoffhochdruckspeicher für ein Common-Rail-Kraftstoffeinspritzsystem einer Brennkraftmaschine, mit einem rohrförmigen Grundkörper, an den mindestens eine Buchse zum Anschließen einer Hochdruckleitung angeschweißt ist.The invention relates to a high-pressure fuel accumulator for a common rail fuel injection system of an internal combustion engine, having a tubular base body, is welded to the at least one socket for connecting a high-pressure line.
Ein derartiger Kraftstoffhochdruckspeicher ist z.B. in der EP 0 866 221 A1 beschrieben. In Common-Rail-Einspritzsystemen fördert eine Hochdruckpumpe, eventuell unter Zuhilfenahme einer vorförderpumpe, den einzuspritzenden Kraftstoff aus einem Tank in den zentralen Kraftstoffhochdruckspeicher, der als Common-Rail bezeichnet wird. Von dem Rail führen Kraftscoffleitungen zu den einzelnen Injektoren, die den Zylindern der Brennkraftmaschine zugeordnet sind. Die Injektoren werden in Abhängigkeit von den Betriebsparametern der Brennkraftmaschine einzeln von der Motorelektronik angesteuert, um Kraftstoff in den Brennraum der Brennkraftmaschine einzuspritzen.Such a high-pressure fuel storage is e.g. in EP 0 866 221 A1. In common-rail injection systems, a high-pressure pump, possibly with the aid of a prefeed pump, conveys the fuel to be injected from a tank into the central high-pressure fuel accumulator, which is referred to as a common rail. Power rail lines lead from the rail to the individual injectors which are assigned to the cylinders of the internal combustion engine. The injectors are controlled individually by the engine electronics as a function of the operating parameters of the internal combustion engine in order to inject fuel into the combustion chamber of the internal combustion engine.
Aus den Patent Abstracts of Japan Bd. 1998, Nr. 11, 30. September 1998 (1998-09-30) & JP 10 169527 A ist ein Kraftsuoffhochdruckspeicher mit einer angeschweißten Buchse bekannt. Dabei wiest der Kraftstoffhochdruckspeicher eine Bohrung auf, die von dessen Innenraum ausgeht und in einem Aufnahmetrichter mündet. Dieser Aufnahmetrichter dient zur Aufnahme einer Hochdruckleitung, die durch eine Pressschraube hochdruckdicht gegen den Aufnahmetrichter gepresst wird.From the Patent Abstracts of Japan vol. 1998, no. 11, September 30, 1998 (1998-09-30) & JP 10 169527 A a Kraftuoffhochdruckspeicher with a welded socket is known. In this case, the high-pressure fuel accumulator wures a bore, which emanates from its interior and opens into a receiving hopper. This receiving hopper serves to receive a high-pressure line, which is pressed by a compression screw high pressure-tight against the receiving hopper.
Aufgabe der Erfindung ist es, die Qualität und die Sicherheit an den Hochdruckanschlussstellen bei einem Kraftstoffhochdruckspeicher der eingangs geschilderten Art zu verbessern. Außerdem soll der erfindungsgemäße Kraftstoffhochdruckspeicher einfach aufgebaut und kostenganstig herstellbar sein.The object of the invention is to improve the quality and safety of the high-pressure connection points in a high-pressure fuel accumulator of the type described. In addition, the inventive High-pressure fuel storage be simple and inexpensive to produce.
Die Aufgabe ist bei einem Kraftstoffhochdruckspeicher für ein Common-Rail-Kraftstoffeinspritzsystem einer Brennkraftmaschine mit den Merkmalen des Anspruchs 1 gelöst.The object is achieved in a high-pressure fuel accumulator for a common rail fuel injection system of an internal combustion engine having the features of claim 1.
Der Bund dient zum Einbringen des zum Anschweißen der Buchse erforderlichen Schweißstroms. Bei herkömmlichen Buchsen ohne Bund wird die Schweißelektrode an dem von dem Grundkörper abgewandten Ende der Buchse angelegt. Dabei können Schweißspritzer in das Innere der Buchse gelangen und ein dort vorgesehenes Gewinde beschädigen. Außerdem kann sich die Geometrie im Inneren der Buchse aufgrund der beim Schweißen auftretenden Temperaturen in unerwünschter Weise verformen. Diese Nachteile werden durch die Bereitstellung des erfindungsgemäßen Bundes als Angriffsstelle für eine Schweißelektrode vermieden. Ein weiterer Vorteil ist darin zu sehen, dass der Bund eine Angriffsfläche für eine Kraft bildet, mit der die Buchse beim Schweißen gegen den Grundkörper gedrückt wird. Eine solche Kraft kann praktischerweise auch mit der Schweißelektrode aufgebracht werden.The collar serves to introduce the welding current required to weld the socket. In conventional bushes without collar, the welding electrode is applied to the end remote from the base of the socket. This spatter can get into the interior of the socket and damage a thread provided there. In addition, the geometry inside the bushing may undesirably deform due to the temperatures encountered during welding. These disadvantages are avoided by providing the collar according to the invention as a point of attack for a welding electrode. Another advantage is the fact that the collar forms an attack surface for a force with which the socket is pressed against the body during welding. Such a force may conveniently be applied to the welding electrode.
Dadurch, dass von dem Innenraum des rohrförmigen Grundkörpers eine Bohrung ausgeht, die in einen Aufnahmetrichter mündet, der sich nach außen hin erweitert und zur Aufnahme eines Endes der Hochdruckleitung dient, das durch eine im Wesentlichen hohlzylinderförmige Pressschraube hochdruckdicht gegen den Aufnahmetrichter gepresst wird, und dass die Dichtstelle von einem im Wesentlichen hohlzylinderförmigen Isolierring umgeben ist. Durch den Isolierring wird ein elektrischer Nebenschluss beim Anschweißen der Buchse sicher verhindert. Außerdem gewährleistet der Isolierring, dass beim Anschweißen der Buchse keine Schweißspritzer zur Dichtstelle gelangen können.Characterized in that from the interior of the tubular base body, a bore emanates, which opens into a receiving hopper, which widens outwardly and serves to receive an end of the high-pressure line, by a substantially hollow cylindrical Press screw is pressed high-pressure-tight against the receiving hopper, and that the sealing point is surrounded by a substantially hollow cylindrical insulating ring. The insulating ring safely prevents electrical shunting when welding the socket. In addition, the insulating ring ensures that no welding spatter can reach the sealing point when welding the socket.
Eine weitere besondere Ausführungsart der Erfindung ist dadurch gekennzeichnet, dass der Isolierring in die Buchse vormontiert ist, und dass die innere Mantelfläche des Isolierrings an der äußeren Mantelfläche eines Vorsprungs anliegt, in dem der Aufnahmetrichter ausgebildet ist. Dadurch wird erreicht, dass die Buchse bei der Montage vor dem Anschweißen relativ zu dem Vorsprung zentriert wird.Another particular embodiment of the invention is characterized in that the insulating ring is pre-assembled in the socket, and that the inner circumferential surface of the insulating ring bears against the outer circumferential surface of a projection in which the receiving hopper is formed. This ensures that the sleeve is centered during assembly prior to welding relative to the projection.
Eine weitere besondere Ausführungsart der Erfindung ist dadurch gekennzeichnet, dass das Ende der Hochdruckleitung kugelig ausgebildet ist, und dass der Innendurchmesser der Pressschraube größer als der Außendurchmesser der Hochdruckleitung ist. Dadurch wird eine Freistellung der Hochdruckleitung relativ zu der Buchse ermöglicht. Das liefert den Vorteil, dass eventuelle Einbautoleranzen im Motorraum ausgeglichen werden können.Another particular embodiment of the invention is characterized in that the end of the high pressure line is spherical, and that the inner diameter of the extruder screw is greater than the outer diameter of the high pressure line. This allows an exemption of the high pressure line relative to the socket. This provides the advantage that any installation tolerances in the engine compartment can be compensated.
Eine weitere besondere Ausführungsart der Erfindung ist dadurch gekennzeichnet, dass die zu dem rohrförmigen Grundkörper gewandte Stirnseite der Buchse nach innen abgeschrägt ist. Durch die Abschrägung wird der Zugang zu der Verbindungsstelle zwischen der Buchse und dem rohrförmigen Grundkörper erleichtert.Another particular embodiment of the invention is characterized in that the facing to the tubular body end face of the socket is chamfered inwards. The bevel facilitates access to the joint between the bush and the tubular body.
