Spielausgleich in den Gelenken Backlash compensation in the joints
einer Koppelstange Die Erfindung betrifft eine Koppelstange zwischen mindestens zwei Anlenkhebeln, insbesondere als Verbindung der Stellhebel zweier Einspritzpumpen, wobei die Anlenkhebel mit der Koppelstange über Gelenke verbunden sind. a coupling rod The invention relates to a coupling rod between at least two pivot levers, in particular as a connection between the two adjusting levers Injection pumps, the linkage lever being connected to the coupling rod via joints are.
Die Koppelstange bestimmt die Lage der Anlenkhebel. Auftretender Verschleiß in den Gelenken verändert die Lage der Anlenkhebel sowie der Regelstangen und damit den Füllungsgrad der Einspritzpumpe.The coupling rod determines the position of the link lever. Occurring wear in the joints changed the position of the linkage lever and the control rods and thus the filling level of the injection pump.
Heute verwendete Verbindungsgestänge, die offenliegen und exakt geführt werden müssen, haben vielfach ausgebuchste Gelenke. Diese Gelenkgestaltung erfordert eine genaue Fertigung und Einhaltung der Toleranzen für die Lagerbuchsen.Connecting rods used today that are exposed and precisely guided often have bulging joints. This joint design requires accurate manufacture and compliance with the tolerances for the bearing bushes.
Diese Gelenke müssen zur Vermeidung von Verschleiß abgedichtet und geschmiert werden.These joints must be sealed and sealed to prevent wear be lubricated.
Der Erfindung liegt die Aufgabe zugrunde, die über eine Koppelstange bestimmte Lage von Anlenkhebeln zueinander auch bei Verschleiß in den Anlenkpunkten der Koppelstange durch einfache Maßnahmen weitgehend unverändert aufrechtzuerhalten.The invention is based on the object of a coupling rod certain position of the linkage levers to each other even with wear in the linkage points to maintain the coupling rod largely unchanged by simple measures.
Diese Aufgabe wird mit dem im Kennzeichen des Anspruchs 1 genannten Merkmal gelöst. Auftretender Verschleiß wird stets in eine Richtung hin verlagert. Diese Anordnung ermöglicht bei offenliegenden, wartungsfreien Koppelstangen für genaue Steuerbewegungen auch bei Verschleiß in den Gelenken nahezu gleiche Lagen der Anlenkhebel zueinander.This task is cited in the characterizing part of claim 1 Feature solved. Any wear that occurs is always shifted in one direction. This arrangement allows for exposed, maintenance-free coupling rods for exact control movements even with wear in the joints almost identical positions the linkage lever to each other.
In Ausgestaltung der Erfindung ist vorgesehen, daß die Kraft größer oder gleich der Stellkraft ist. Dadurch wird sichergestellt, daß die Stellkraft kein Spiel in den Gelenken verursachen kann.In an embodiment of the invention it is provided that the force is greater or is equal to the actuating force. This ensures that the actuating force cannot cause any play in the joints.
Die Kraftbeaufschlagung erfolgt vorteilhaft durch eine Schraubenfeder, die wartungsfrei, kostengünstig, leicht austauschbar sowie bei entsprechender Führung der Feder auch auslenkbar ist, z. B. durch die Ansenkung in der Auflage und dem Anlenkhebel.The application of force is advantageously carried out by a helical spring, The maintenance-free, inexpensive, easily exchangeable and with appropriate guidance the spring is also deflectable, e.g. B. by the countersink in the edition and the Linkage lever.
Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und der Zeichnung, in der ein Ausführungsbeispiel vereinfacht dargestellt ist, das im folgenden näher beschrieben wird. Es zeigt: Fig. 1 eine Seitenansicht auf zwei über eine Koppelstange verbundene Stellhebel von Einspritzpumpen; Fig. 2 eine Draufsicht auf die Koppelstange in Fig. 1 mit teilgeschnittenen Gelenken.Further features of the invention emerge from the further claims, the description and the drawing, in which an exemplary embodiment is shown in simplified form which is described in more detail below. It shows: FIG. 1 a side view on two control levers of injection pumps connected by a coupling rod; Fig. 2 shows a plan view of the coupling rod in FIG. 1 with partially sectioned joints.
Das in Fig. 1 dargestellte verbindungsgestänge einer Drehzahlverstellung für einen Dieselmotor besteht unter anderem aus den Anlenkhebel 5, 6, die an einem Ende an der Einspritzpumpe 1, 2 drehbar befestigt sind. An jedem Anlenkhebel 5, 6 ist auf ca. der halben Hebellänge die Regelstange 3, 4 der Einspritzpumpe 1, 2 angelenkt. Am anderen, freien Ende der Anlenkhebel 5, 6, das von der Einspritzpumpe 1, 2 entfernt liegt, ist der Hebel mit einem Ansatz versehen, der als Gelenklager 7, 8 dient. Das Gelenklager 7, 8 ist mit einer Bohrung versehen für den eingreifenden Gelenkbolzen 14, 15, der in der Koppelstange 9 befestigt, z. B. eingeschrumpft ist. Der Spielausgleich im Gelenk erfolgt durch je eine Schraubenfeder 10, 11, die parallel zur Koppelstange 9 angebracht ist. Beide Schraubenfedern 10, 11 liegen auf der gleichen Seite der Anlenkhebel 5, 6, derart, daß ihre Druckkräfte in die gleiche Richtung weisen und die Gelenke 16, 17 kraftbeaufschlagen.The linkage shown in Fig. 1 of a speed adjustment for a diesel engine consists, among other things, of the articulation lever 5, 6, which is attached to a End at the Injection pump 1, 2 are rotatably mounted. On everyone The articulation lever 5, 6 is the control rod 3, 4 of the injection pump at about half the lever length 1, 2 hinged. At the other, free end of the articulation lever 5, 6, that of the injection pump 1, 2 is removed, the lever is provided with an approach that acts as a pivot bearing 7, 8 is used. The pivot bearing 7, 8 is provided with a bore for the engaging Hinge pin 14, 15, which is fastened in the coupling rod 9, for. B. is shrunk. The play compensation in the joint is done by a helical spring 10, 11, which are parallel to the coupling rod 9 is attached. Both coil springs 10, 11 are on the same Side of the pivot lever 5, 6, such that their compressive forces in the same direction point and apply force to the joints 16, 17.
Es kann auch vorteilhaft sein, auf der anderen Seite der Anlenkhebel gleichartig wirkende Zugfedern anzuordnen.It can also be advantageous to have the link lever on the other side similarly acting tension springs to be arranged.
Ebenso kann es zweckmäßig sein, anstatt von Federn andere kräfteausübende Vorrichtungen anzuordnen, so z. B. Kolben/Zylindereinheiten.It can also be useful to use other forces instead of springs To arrange devices, such. B. Piston / cylinder units.
An jedem Anlenkhebel 5, 6 ist in seiner Längsseite im Bereich des Gelenklagers 7, 8 eine Ansenkung vorgesehen, deren Mittelachse sich um 90 ° versetzt zur Achse der Lagerbohrung befindet. Beide Ansenkungen weisen in dieselbe Richtung. In diesen Ansekungen sind die Enden der Schraubenfedern 10, 11 geführt. Eine Ansenkung gleicher Größe ist in die Auflage 12, 13 eingebracht, die als Federabstützung dient und auf der Koppelstange 9 angeschweißt ist. Die Verbindung der Koppelstange 9 mit dem Anlenkhebel 5, 6 erfolgt im Gelenklager 7, 8 durch den Gelenkbolzen 14, 15.On each articulation lever 5, 6 is in its longitudinal side in the area of Joint bearing 7, 8 provided a countersink, the central axis of which is offset by 90 ° to the axis of the bearing bore. Both countersinks point in the same direction. The ends of the coil springs 10, 11 are guided in these countersinks. A countersink the same size is introduced into the support 12, 13, which serves as a spring support and is welded to the coupling rod 9. The connection of the coupling rod 9 with the articulation lever 5, 6 takes place in the pivot bearing 7, 8 through the pivot pin 14, 15.
Fig. 2 zeigt die Draufsicht auf des Verbindungsgestänge.Fig. 2 shows the top view of the connecting rod.
Das übertrieben dargestellte Gelenkspiel 18, 19 wird durch die Federkraft der Schraubenfeder 10, 11, ausgeglichen.The joint play 18, 19, shown exaggerated, is caused by the spring force the coil spring 10, 11, balanced.
Die Schraubenfedern stellen eine spielfreie, kraftschlüssige Anlage des Anlenkhebels 5, 6 an den Gelenkbolzen 14, 15 sicher. Die Federkraft muß so ausgelegt werden, daß bei normalen Regelvorgängen kein Anlagewechsel stattfindet, d. h. die Federkraft wird gleich oder größer als die Stellkraft ausgelegt. Das Einsetzen einer zu starken Feder sollte dagegen vermieden werden, da dies einen unnötig hohen Gelenkverschleiß zur Folge hätte. Vorteilhaft sind gleich große Federkräfte, die auf die Gelenke einwirken, so daß ein zwangsweise vorliegender Verschleiß in beiden Gelenken etwa gleich ist. So wird gewährleistet, daß die Stellung der Anlenkhebel zueinander durch den Spielausgleich unverändert bleibt. Im gezeiyten Ausführungsbeispiel haben die Schraubenfedern zweckmäßig gleiche Federkonstanten; die Schraubenfedern können vorteilhaft auch gleich ausgebildet sein.The coil springs provide a backlash-free, force-fit system of the linkage lever 5, 6 on the hinge pin 14, 15 securely. The spring force must be designed in this way that no change of system takes place during normal control processes, d. H. the The spring force is designed to be equal to or greater than the actuating force. The insertion of a On the other hand, too strong a spring should be avoided, as this causes unnecessarily high joint wear would result. Equally large spring forces acting on the joints are advantageous act so that an inevitable wear in both joints about is equal to. This ensures that the position of the linkage levers to one another the backlash compensation remains unchanged. In the illustrated embodiment, the Helical springs expediently have the same spring constants; the coil springs can be beneficial also be designed the same.
