Abstract

The invention relates to a distributor injection pump comprising a housing (10) and a roller ring (12) which is positioned in said housing in an adjustable manner and is provided with at least one roller (20). A cam plate (28) for actuating a pump piston can be supported on said roller. The roller is mounted in the roller ring using a bolt (24) which extends in a radial direction in relation to the central axis of the roller ring. The aim of the invention is to prevent damage to the housing caused by the radial force exerted outwards on the bolt that occurs when the roller is under stress. To achieve this, a support element (40) is provided on the radial end of the bolt (24).

Description

Verteilereinspritzpumpe Distributor injection pump
Stand der TechnikState of the art
Die Erfindung betrifft eine Verteilereinspritzpumpe mit einem Gehäuse und einem in dem Gehäuse verstellbar angeordneten Rollenring, der mit minde- stens einer Rolle versehen ist, an der sich eine Nockenscheibe abstützen kann, die zur Betätigung eines Pumpenkolbens dient, wobei die Rolle in dem Rolienring mittels eines Bolzens gelagert ist, der sich relativ zur Mittelachse des Rollenrings in radialer Richtung erstreckt.The invention relates to a distributor injection pump with a housing and a roller ring which is adjustably arranged in the housing and which is provided with at least one roller on which a cam disk can be supported, which serves to actuate a pump piston, the roller in the roller ring using a Bolt is mounted, which extends in the radial direction relative to the central axis of the roller ring.
Eine solche Verteilereinspritzpumpe dient dazu, einen Zylinder einer Verbrennungskraftmaschine im richtigen Zeitpunkt mit der richtigen Menge an Kraftstoff zu versorgen. Zu diesem Zweck ist der Pumpenkolben vorgesehen, der mit der Nockenscheibe verbunden ist. Wenn die Nockenscheibe relativ zum Rolienring gedreht wird, wälzt sich ihre mit Nocken versehene Oberfläche auf den Rollen ab. Auf diese Weise erfährt die Nockenscheibe eine Hubbewegung, die zum Pumpenkolben übertragen wird. Durch die bei einem Hub auf die Bolzen einwirkenden Kräfte ergibt sich eine auf den Bolzen wirkende periodische Kraftkomponente, welche den Bolzen bezüglich der Mittelachse des Rollenrings in radialer Richtung nach außen beaufschlagt. Dies kann dazu führen, daß bei hohen Belastungen des Rolleπrings sich die Bolzen, die üblicherweise aus Stahl bestehen, mit ihrem radial außenliegenden Ende in den diesem Ende gegenüberliegenden Teil des Gehäuses, das meist aus Aluminium besteht, einhämmern oder eingraben Dies kann langfristig die Funktioπssicherheit der Einspritzpumpe beeinträchtigenSuch a distributor injection pump serves to supply a cylinder of an internal combustion engine with the right amount of fuel at the right time. For this purpose, the pump piston is provided, which is connected to the cam disk. When the cam disc is rotated relative to the Rolienring, its cam surface rolls on the rollers. In this way, the cam disc experiences a stroke movement that is transmitted to the pump piston. The forces acting on the bolt during a stroke result in a periodic force component acting on the bolt, which acts on the bolt with respect to the central axis of the roller ring in the radial direction to the outside. This can lead to the fact that, under high loads on the roller ring, the bolts, which usually consist of steel, lie radially on the outside Hammer or dig into the end of that part of the housing opposite this end, which usually consists of aluminum. This can impair the reliability of the injection pump in the long term
Der Erfindung egt daher die Aufgabe zugrunde, eine Verteilereinspπtzpumpe der eingangs genannten Art dahingehend weiterzubilden, daß ein Eingraben der Bolzen des Rollenrings in das Gehäuse der Verteiiereinspπtzpumpe zuverlässig verhindert wirdThe invention is therefore based on the object of further developing a distributor injection pump of the type mentioned at the outset in such a way that the bolts of the roller ring are reliably prevented from being buried in the housing of the distribution injection pump
Vorteile der ErfindungAdvantages of the invention
Bei einer Verteilereinspπtzpumpe mit den Merkmalen des Patentanspruchs 1 dient das Abstutzelement dazu, die auf den Bolzen einwirkende Axialkraft groß- flachig in das Gehäuse der Verteilereinspπtzpumpe einzuleiten Somit wird die lokal von dem Bolzen auf das Gehäuse ausgeübte Verschleißkraft stark verringert, so daß es zu keinen Materialschaden kommen kannIn a distributor injection pump with the features of claim 1, the support element serves to introduce the axial force acting on the bolt over a large area into the housing of the distributor injection pump. Thus, the wear force locally exerted by the bolt on the housing is greatly reduced, so that it does not cause any material damage can come
Gemäß einer bevorzugten Ausfuhrungsform der Erfindung ist vorgesehen, daß das Abstutzelement eine am Rollenring angeordnete Klammer ist, die in Off- nungen am Rollenring eingeclipst ist Die Klammer überdeckt das radial außenliegende Ende des Bolzens und wird, wenn auf den Bolzen eine Axial kraft ausgeübt wird, nach außen zum Gehäuse der Verteilereinspritzpumpe hin verformt, so daß es am Gehäuse anliegt und die auf den Bolzen wirkende Axialkraft über eine große Flache in das Gehäuse einleitet Als Material für die Klammer wird vorzugsweise Stahl gewähltAccording to a preferred embodiment of the invention, it is provided that the support element is a clamp arranged on the roller ring, which is clipped into openings on the roller ring. The clamp covers the radially outer end of the bolt and, when an axial force is exerted on the bolt, deformed towards the outside of the distributor injection pump housing so that it rests on the housing and introduces the axial force acting on the bolt over a large area into the housing. Steel is preferably chosen as the material for the clamp
Gemäß einer alternativen Ausfuhrungsform ist vorgesehen, daß das Abstutzelement am Gehäuse angeordnet ist Bei dieser Ausfuhrungsform ist das Abstutzelement, das vorzugsweise aus Stahl besteht, als Einlegeteil ausgebildet, das einen direkten Kontakt zwischen dem aus Stahl bestehenden Bolzen und dem aus Aluminium bestehenden Gehäuse verhindert Auch bei dieser Aus- führungsform wird eine aif den Bolzen wirkende Axialkraft zunächst auf das Abstützelement Übertrager,, von dem es wiederum großflächig ins Gehäuse eingeleitet wird.According to an alternative embodiment it is provided that the support element is arranged on the housing. In this embodiment, the support element, which is preferably made of steel, is designed as an insert which prevents direct contact between the steel bolt and the aluminum housing this out In the exemplary embodiment, an axial force acting on the bolt is first applied to the support element of the transformer, from which it is again introduced into the housing over a large area.
Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous refinements of the invention result from the subclaims.

Die Erfindung wird nachfolgend unter Bezugnahme auf eine bevorzugte Ausführungsform beschrieben, die in den beigefügten Zeichnungen dargestellt ist. In diesen zeigen:The invention is described below with reference to a preferred embodiment which is illustrated in the accompanying drawings. In these show:

Beschreibung des AusführungsbeispielsDescription of the embodiment
In Fig. 1 ist in einem schematischen Teilschnitt eine erfindungsgemäße Verteilereinspritzpumpe gezeigt, die dazu dient, Kraftstoff in einen Zylinder einer Verbrenπungskraftmaschine einzuspritzen. Die Einspritzpumpe enthält ein Gehäuse 10, in welchem ein Rollenring 12 angeordnet ist. Der Rollenring 12 weist einen Inneπring 14 und einen Außenring 16 auf, die zwischen sich eine ringförmige Aufnahme 18 bilden. Innerhalb der ringförmigen Aufnahme 18 sind mehrere Rollen 20 angeordnet, die über jeweils eine Buchse 22 auf einem Bolzen 24 gelagert sind. Jeder Bolzen 24 erstreckt sich bezüglich einer Mittelachse des Rollenrings 12 in radialer Richtung und ist mit seinem radial innen- liegenden Ende im Innenring 14 aufgenommen, während sein radial außenliegendes Ende im Außenring 16 aufgenommen ist. Zwischen dem Außenring 16 und jeder Rolle 20 ist noch eine Anlaufscheibe 26 angeordnet.1 shows a schematic partial section of a distributor injection pump according to the invention, which serves to inject fuel into a cylinder of an internal combustion engine. The injection pump contains a housing 10 in which a roller ring 12 is arranged. The roller ring 12 has an inner ring 14 and an outer ring 16, which form an annular receptacle 18 between them. A plurality of rollers 20 are arranged within the annular receptacle 18, each of which is mounted on a pin 24 via a bushing 22. Each bolt 24 extends with respect to a central axis of the roller ring 12 in the radial direction and is with its radially inner lying end received in the inner ring 14, while its radially outer end is received in the outer ring 16. A thrust washer 26 is also arranged between the outer ring 16 and each roller 20.
Mit den Rollen 20 wirkt eine Nockenscheibe 28 zusammen, die von einer Druckfeder 30 gegen die Rollen 20 beaufschlagt wird. Mit der Nockenscheibe 28 ist ein Fortsatz 32 verbunden, der wiederum mit einem (nicht dargestellten) Pumpeπkolben verbunden ist.A cam disk 28 interacts with the rollers 20 and is acted upon by a compression spring 30 against the rollers 20. An extension 32 is connected to the cam disk 28, which in turn is connected to a pump piston (not shown).
Es ist eine Antriebswelle 36 vorgesehen, die über eine Kupplung 38 die Nockenscheibe 28 in Drehung versetzen kann. Die Nockenscheibe 28 läuft dann mit ihrer den Rollen 20 zugewandten, mit Nocken versehenen Fläche auf den Rollen 20 ab, wodurch sich eine periodische Hubbewegung der Nockenscheibe 28 ergibt, die zum Pumpenkolben übertragen wird, der schließlich den einzuspritzenden Kraftstoff fördert.A drive shaft 36 is provided which can set the cam disk 28 in rotation via a clutch 38. The cam disc 28 then runs with its cam-facing surface on the rollers 20, which results in a periodic lifting movement of the cam disc 28, which is transmitted to the pump piston, which finally conveys the fuel to be injected.
Zur Einstellung des Einspritzzeitpunktes relativ zum Kurbelwellenwinkel der versorgten Verbrennungskraftmaschine ist noch ein (nicht dargestellter) Spritzversteller vorgesehen, mittels dem der Rollenring 12 im Gehäuse um einen be- stimmten Winkel verdreht werden kann. Der Aufbau und die Funktionsweise eines solchen Spritzverstellers sind allgemein bekannt, so daß sie hier nicht wiedergegeben werden.To adjust the injection timing relative to the crankshaft angle of the supplied internal combustion engine, a spray adjuster (not shown) is also provided, by means of which the roller ring 12 can be rotated in the housing by a certain angle. The structure and mode of operation of such a spray adjuster are generally known, so that they are not reproduced here.
Am Rollenring 12 ist ein Abstützelement 40 (siehe auch die Figuren 2 und 3) angebracht, das mit zwei abgebogenen Enden 42 versehen ist, die als Federlaschen dienen. Jedes abgebogene Ende greift in eine Öffnung 44 ein, die am Außenring 16 des Rollenrings 12 ausgebildet ist. Das Abstützelement 40 erstreckt sich über einen Winkelbereich, der sehr viel größer als der Winkelbereich ist, über den sich das radial außenliegende Ende des entsprechenden Bolzens 24 erstreckt, und deckt das radial außeπiiegende Ende des entsprechenden Bolzens im wesentlichen ab. Um zu verhindern, daß - o -A support element 40 (see also FIGS. 2 and 3) is attached to the roller ring 12 and is provided with two bent ends 42, which serve as spring tabs. Each bent end engages in an opening 44 which is formed on the outer ring 16 of the roller ring 12. The support element 40 extends over an angular range which is very much larger than the angular range over which the radially outer end of the corresponding bolt 24 extends, and essentially covers the radially outer end of the corresponding bolt. To prevent that - o -
das Abstutzelement 40 über den Außenumfang des Außenringes 16 hiπaussteht, ist jedes Abstutzelement in einer Aussparung 46 angeordnet, die sich zwischen zwei demselben Abstutzelement 40 zugeordneten Offnungen 44 erstrecktthe support element 40 protrudes beyond the outer circumference of the outer ring 16, each support element is arranged in a recess 46 which extends between two openings 44 assigned to the same support element 40
Wenn beim Betrieb der Verteilereinspritzpumpe auf die Rollen 20 eine große Kraft ausgeübt wird, ergibt sich daraus eine in der Richtung des Pfeils F von Fig 3 wirkende Axialkraft Bei einer daraus resultierenden Verschiebung des Bolzens 24 druckt dieser das Abstutzelemeπt 40 nach außen, so daß dieses sich am Gehäuse 10 der Verteilereinspritzpumpe abstutzt Auf diese Weise ergibt sich eine große Beruhrflache, über die die wirkende Axialkraft in das Gehäuse eingeleitet werden kannIf a large force is exerted on the rollers 20 during operation of the distributor injection pump, this results in an axial force acting in the direction of the arrow F in FIG. 3. When the bolt 24 is displaced as a result, the bolt 24 presses the support member 40 outward, so that it becomes self-supporting supported on the housing 10 of the distributor injection pump. This results in a large contact surface, via which the acting axial force can be introduced into the housing
Als Material für das Abstutzeiemeπt 40 kann insbesondere Stahl verwendet werden Alternativ ist auch die Verwendung eines geeigneten Kunststoffes denkbar Abweichend zur gezeigten Ausfuhrungsform, bei der ein separates Abstutzelement für jeden Bolzen verwendet wird, ist auch die Verwendung eines einzigen Abstutzelementes für alle Bolzen denkbar Auch kann anstelle des gezeigten Abstutzelementes aus Flachmateπal beispielsweise eine Draht- klammer verwendet werden, die entweder den gesamten Außenring 16 umschließt und im Bereich der axial außen egenden Enden der Bolzen 24 angeordnet ist oder jeweils separat in die Öffnungen 44 eingeclipst wird Steel in particular can be used as the material for the support member 40. Alternatively, the use of a suitable plastic is also conceivable. In contrast to the embodiment shown, in which a separate support element is used for each bolt, the use of a single support element for all bolts is also conceivable of the support element shown made of flat material, for example, a wire clip can be used, which either surrounds the entire outer ring 16 and is arranged in the region of the axially outer ends of the bolts 24 or is clipped separately into the openings 44
