Abstract
Description
Rollenstößel roller plunger
Die Erfindung betrifft einen Rollenstößel, insbesondere für eine Kraftstoffhochdruckpumpe oder für einen Ventiltrieb einer Brennkraftmaschine, mit einem Gehäuse, wel- ches bei seiner antriebsseitigen Stirn eine lose Rolle für einen periodischen Huberzeuger hat, die in einer einteilig zu einem Brückenstück gehörenden Schale verläuft, welches Brückenstück das Gehäuse, hieran einteilig angebunden, durchragt sowie in Richtung zu einer abtriebsseitigen Stirn des Gehäuses eine Anlage für ein Stößelfolgeteil aufweist und wobei der Stößel über wenigstens ein separat gefügtes Anlaufmit- tel für Stirnseiten der Rolle verfügt. The invention relates to a roller tappet, in particular for a high-pressure fuel pump or for a valve train of an internal combustion engine, with a housing which has at its drive-side end a loose role for a periodic Huberzeuger which runs in a one piece to a bridge piece shell, which bridge piece the housing, connected in one piece therewith, protrudes through and in the direction of a driven-side end of the housing has a contact for a follower part and wherein the plunger has at least one separately joined Anlaufmit- tel for end faces of the roller.
Ein gattungsgemäßer Rollenstößel, hier für eine Kraftstoffhochdruckpumpe, geht aus der DE 10 2012 212 579 A1 , Fig. 1 A, 1 B hervor. Als separates Anlaufmittel ist ein Sprengring dargestellt, welcher die Rolle unmittelbar stirnseitig umgreift und in einer Ringnut des Gehäuses sitzt. Die Rolle läuft somit direkt an einem vergleichsweise schmalen Innenmantel des Sprengrings an. A generic roller tappet, here for a high-pressure fuel pump, is shown in DE 10 2012 212 579 A1, Fig. 1 A, 1 B out. As a separate starting means a snap ring is shown, which surrounds the roller directly on the front side and sits in an annular groove of the housing. The roller thus runs directly on a comparatively narrow inner shell of the snap ring.
Ein weiterer Rollenstößel mit einer unmittelbaren axialen Sprengringsicherung für dessen Rolle geht aus den Fig. 1 , 2 der DE 10 2006 028 348 B3 hervor. Das draht- ähnliche Sicherungsbauteil sitzt hierbei in einer Umlaufnut am Innenmantel des Gehäuses des Stößels. Stirnseiten der Rolle laufen zur Axialsicherung dieser wiederum innenseitig an dem Ringdraht an. Another roller tappet with an immediate axial snap ring for its role is shown in FIGS. 1, 2 of DE 10 2006 028 348 B3. In this case, the wire-like securing component is seated in a circumferential groove on the inner casing of the housing of the tappet. End sides of the roller run to the axial securing this in turn on the inside of the ring wire.
Bei den vorgenannten Gestaltungen erweist sich die axiale Fixierung der losen Rolle über das jeweilige Ringteil als zu instabil und Undefiniert. Gleichzeitig ist mit starkem Verschleiß im stirnseitigen Kontaktbereich zu rechnen. In the aforementioned designs, the axial fixation of the loose roller over the respective ring part proves to be too unstable and undefined. At the same time, heavy wear is to be expected in the frontal contact area.
Die DE 10 2012 222 217 A1 offenbart einen Rollenstößel, von dessen nockenseitigem Boden sich zwei gegenüberliegende, halbkreisähnliche Klips zur Axialfixierung der Rolle ausgehen. Aus der DE 10 201 1 083 571 A1 ist ein gebauter Rollenstößel entnehmbar, dessen Rolle in einer Tasche eines separaten Bodens gelagert ist, auf dem noch ein Halteelement eingepresst ist. Axial ist die Rolle durch Querwände des Stützelements fixiert. DE 10 2012 222 217 A1 discloses a roller tappet, from the cam-side bottom of which two opposite semicircle-like clips for axial fixing of the roller extend. From DE 10 201 1 083 571 A1 a built-up roller tappet can be removed whose roller is mounted in a pocket of a separate bottom, on which a retaining element is still pressed. Axially, the role is fixed by transverse walls of the support element.
Des Weiteren zeigt die DE 2 361 679 A eine Pumpenkolbenanordnung mit einer no- ckengegenlaufenden, in einem Gehäuse einsitzenden Rolle. Eine an einem nockenfernen Boden anliegende Halteklammer umgreift hierbei einen Außenmantel des Stößels mit zwei parallelen Axialfingern. Freie Enden dieser Finger sichern hierbei die Rolle axial. Furthermore, DE 2 361 679 A shows a pump piston arrangement with a counter-rotating roller seated in a housing. A voltage applied to a cam-distal bottom retaining clip engages an outer jacket of the plunger with two parallel axial fingers. Free ends of these fingers secure the role axially.
Zudem geht aus der DE 10 2006 041 673 A1 ein Rollenstößel in einer Hochdruckpumpe mit einer einem Exzenter gegenlaufenden Rolle hervor. Letztgenannte sitzt in einer Abstütztasche des Gehäuses. Im Kontaktbereich hierbei sind spezielle Ver- Schleißschutzmaßnahmen vorgesehen. In addition, DE 10 2006 041 673 A1 discloses a roller tappet in a high-pressure pump with a roller running counter to an eccentric. The latter sits in a support pocket of the housing. In the contact area, special wear protection measures are provided.
Schließlich wird auf den Rollenstößel nach der DE 10 2009 056 303 A1 verwiesen. In dessen nockenseitiger Aufnahme für die Rolle ist eine separate Schale zur unmittelbaren Lagerung der Rolle vorgesehen. Ein lateraler Anlauf für die Rolle erfolgt an spezi- eil hergerichteten Innenmantelabschnitten eines Hemdes des Gehäuses. Die Schale kann sich im Betrieb schiefstellen, muss separat gehalten werden und kann ungüns- tigstenfalls zu einer Beeinflussung der Laufbahn der Rolle führen. Außerdem gestaltet sich der stirnseitige Anlauf der Rolle am Gehäuse als fertigungstechnisch vergleichsweise schwierig. Finally, reference is made to the roller tappet according to DE 10 2009 056 303 A1. In the cam-side receptacle for the role of a separate shell for direct storage of the role is provided. A lateral start-up for the roll takes place on specially prepared inner shell sections of a shirt of the housing. The shell may skew during operation, must be kept separate and, in the worst case, may affect the roller's track. In addition, the frontal start-up of the role on the housing designed as a manufacturing technology comparatively difficult.
Es ist Aufgabe der Erfindung, einen Rollenstößel mit einer fest und verschleißarm fixierten losen Rolle zu kreieren. It is an object of the invention to create a roller tappet with a fixed and low-wear fixed loose role.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass als Anlaufmittel zwei in Ausnehmungen eines Hemdes des Gehäuses sitzende Scheiben appliziert sind, gegen deren Innenseiten die Rolle mit ihren Stirnseiten läuft, welche Scheiben bündig oder eingerückt zu einem Außenmantel des Hemdes des Gehäuses angeordnet sowie über wenigstens einen das Gehäuse in einer respektiven Ringnut dessen Außenmantels umspannenden Sicherungsring / Sprengring lagefixiert sind, der gleichfalls in einem Schlitz der jeweiligen Scheibe sitzt. According to the invention, this object is achieved in that two discs seated in recesses of a shirt of the housing are applied as starting means, against the insides of which the roller runs with its end faces, which discs are flush or indented to an outer jacket of the shirt of the housing arranged and fixed in position over at least one housing in a respectful annular groove whose outer sheath spanning circlip / snap ring, which also sits in a slot of the respective disc.
Durch diese Maßnahmen liegt ein Stößel ohne die zitierten Nachteile vor. Es kommt nicht mehr zu Lageabweichungen der leicht montierbaren Rolle. Der stirnseitige Rollenanlauf erfolgt nunmehr unmittelbar über„feste" Scheiben. Letztgenannte, welche auch lediglich nur scheibenähnlich sein können, lassen sich einfach, bspw. durch Prä- gen oder Stanzen, fertigen und zupaaren. These measures provide a plunger without the cited disadvantages. It no longer comes to positional deviations of easy mountable role. The end-face roller start now takes place directly via "fixed" washers, the latter, which can also only be disc-like, can be easily manufactured, for example by embossing or punching, and mated.
Eine simple Halterung für die Scheiben erfolgt erfindungsgemäß zugleich über wenigstens einen Ring wie einen Sprengring in einer entsprechenden Ringnut des Gehäuses. Der Ring wiederum sitzt in einer schlitzartigen Nut der jeweiligen Scheibe, diese fixierend, ein. Alternativ können die Scheiben auch eingeschraubt, verstemmt, verklebt, verlötet oder verschweißt sein. A simple holder for the discs is carried out according to the invention at the same time via at least one ring such as a snap ring in a corresponding annular groove of the housing. The ring in turn sits in a slot-like groove of the respective disc, this fixing, a. Alternatively, the discs can also be screwed, caulked, glued, soldered or welded.
Gemäß einer weiteren Fortbildung der Erfindung geht das Brückenstück unmittelbar vom oberen, antriebsseitigen Rand des Gehäuses aus, so dass sich eine Feinbearbei- tung der Schale (Schleifen, Finishen wie Polieren etc.) als vergleichsweise einfach erweist. According to a further development of the invention, the bridge piece extends directly from the upper, drive-side edge of the housing, so that a fine machining of the shell (grinding, finishing such as polishing, etc.) proves to be comparatively simple.
Die weiterhin vorgeschlagenen Axialdurchtritte im Brückenstück, welche lochartig sein können, verhindern ein„Aufpumpen" des Stößels im Betrieb und gestatten insbeson- dere einen ungehinderten Durchtritt von Schmiermittel wie Öl oder Kraftstoff. The further proposed axial passages in the bridge piece, which may be hole-like, prevent "pumping" of the plunger during operation and in particular allow unimpeded passage of lubricant such as oil or fuel.
Besonders vorteilhaft ist es hierbei, wenn die vorgenannten Scheiben zumindest an ihren Innenseiten mit einer Verschleißschutzschicht wie einer DLC-Schicht oder dergleichen versehen sind, so dass ein besonders reibungsarmer Rollenanlauf vorliegt. Klar ist, dass ggf. auch die Schale oder Rolle mit einer solchen Schicht versehen sein können. Die Erfindung geht aus der Zeichnung hervor. Es zeigen: It is particularly advantageous in this case if the aforementioned disks are provided at least on their insides with a wear protection layer such as a DLC layer or the like, so that there is a particularly low-friction roller start. It is clear that possibly also the shell or roll can be provided with such a layer. The invention is apparent from the drawing. Show it:
