In the case of the connecting rod (1) designed in accordance with the invention, which is, in particular, a trapezoidal connecting rod, the sliding-bearing bush (3) is bonded into the small end (2). This results in a considerable simplification as regards the manufacturing outlay. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Pleuel gemäß dem Ober­ begriff des Patentanspruchs 1.The invention relates to a connecting rod according to the upper Concept of claim 1.

Es ist im Motorenbau allgemein üblich, bei in dem kleinen Pleuelauge gleitgelagerten Kolbenbolzen in das aus einem Gußwerkstoff hergestellte Pleuel eine Gleitlagerbuchse einzupressen. Dafür müssen sowohl der Außenumfang der Gleitlagerbuchse als auch der Innenumfang des Pleuelauges fein bearbeitet sein. Weiterhin muß ein entsprechendes Preßwerkzeug vorhanden sein. Dieses bekannte Vorgehen ist aufwendig und kostenintensiv.It is common in engine building, in the small one Connecting rod eye sliding piston pin in the from one Connecting rod made of casting material a plain bearing bush press in. For this, both the outer circumference of the Plain bearing bush as well as the inner circumference of the connecting rod eye be finely processed. Furthermore, a corresponding Press tool to be available. This is known procedure complex and cost-intensive.

Der Erfindung liegt die Aufgabe zugrunde, ein Pleuel be­ reitzustellen, bei dem die Befestigung einer Gleitlager­ buchse im kleinen Pleuelauge bei verschiedenen Pleuelaus­ führungen einfach und kostengünstig ausführbar ist.The invention has for its object to be a connecting rod to sit in which the mounting of a plain bearing bush in the small connecting rod eye at different connecting rod housings is easy and inexpensive to perform.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnen­ den Merkmale des Patentanspruchs 1 gelöst. Dadurch, daß die Gleitlagerbuchse mit einer Spielpassung in das kleine Pleuelauge einsetzbar ist und mit der Innenwandung des Pleuelauges verklebbar ist, ist eine sehr einfache und kostengünstige Befestigung der Gleitlagerbuchse möglich. Es brauchen sowohl der Außenumfang der Gleitlagerbuchse als auch der Innenumfang des Pleuelauges nicht fein bear­ beitet zu werden. Weiterhin entfallen aufwendige und teure Einpreßwerkzeuge zum Einpressen der Gleitlagerbuchse. Durch die mit Spielpassung eingesetzte Gleitlagerbuchse ist darüber hinaus sichergestellt, daß die Lagerfläche der Gleitlagerbuchse beim Einschiebvorgang nicht verformt wird. Dadurch entfällt der bei einer eingepreßten Gleit­ lagerbuchse notwendige Schleifvorgang zur entgültigen La­ gersitzbestimmung. Der Kleber übernimmt sowohl die Fixie­ rung der Gleitlagerbuchse als auch die Gewährleistung ei­ ner gleichmäßigen Kraftübertragung der beim Betrieb des Pleuels auftretenden bzw. zu übertragenden Kräfte.According to the invention, this object is characterized by the solved the features of claim 1. As a result of that the plain bearing bush with a clearance fit in the small one Connecting rod eye can be used and with the inner wall of the Connecting rod eye is a very simple and  Cost-effective fastening of the plain bearing bush possible. It needs both the outer circumference of the plain bearing bush as well as the inner circumference of the connecting rod eye to be prepared. Furthermore, there is no need for complex and expensive Press-in tools for pressing in the plain bearing bush. Thanks to the plain bearing bush used with clearance adjustment it is also ensured that the storage area of the Plain bearing bush not deformed during insertion becomes. This eliminates the need for a pressed-in slide bearing bush necessary grinding process to final La seat determination. The glue takes over both the fixie tion of the plain bearing bush as well as the guarantee ner even power transmission when operating the Connecting rod forces occurring or to be transmitted.

Insbesondere eignet sich die erfindungsgemäße Befesti­ gungsart der Gleitlagerbuchse bei im Bereich des kleinen Pleuelauges trapezförmig ausgebildeten Pleuel. Bei diesen mußte bisher entweder eine zylinderförmige Gleitlager­ buchse eingepreßt werden und nachträglich auf die Trapez­ form des Pleuels abgeschliffen werden oder eine entspre­ chend vorgefertigte trapezförmige Gleitlagerbuchse wurde mit aufwendigen Einpreßwerkzeugen in das kleine Pleuelauge eingepreßt. Dabei war es unbedingt notwendig, das Gleitla­ ger genau zu dem Pleuelauge auszurichten, da im eingepreß­ ten Zustand ein Verdrehen der Gleitlagerbuchse gegenüber dem Pleuelauge nicht mehr möglich war. Diese Nachteile sind durch die erfindungsgemäße Befestigungsart bei einem Trapezpleuel nicht mehr gegeben, so daß die erfindungsge­ mäße Befestigung für ein Trapezpleuel besonders geeignet ist.The fastener according to the invention is particularly suitable type of bearing bushing in the area of the small one Conrod eyes with trapezoidal conrods. With these So far, either had a cylindrical slide bearing be pressed in and subsequently on the trapezoid be ground off the shape of the connecting rod or a corresponding prefabricated trapezoidal plain bearing bush with elaborate press-in tools into the small connecting rod eye pressed in. It was absolutely necessary to use the Gleitla ger align exactly to the connecting rod eye, because in the pressed condition of the slide bearing bush rotating the connecting rod eye was no longer possible. These disadvantages are by the type of attachment according to the invention in a Trapezoidal connecting rods no longer exist, so that the fiction moderate fastening particularly suitable for a trapezoidal connecting rod is.

Weitere vorteilhafte Weiterbildungen der Erfindung sind der Zeichnungsbeschreibung zu entnehmen, in der ein in der Figur dargestelltes Ausführungsbeispiel der Erfindung be­ schrieben ist.Further advantageous developments of the invention are can be found in the description of the drawing, in which one in the Figure shown embodiment of the invention be is written.

Es zeigt die einzige Figur:It shows the only figure:

einen Schnitt durch ein Trapezpleuel mit einer erfindungsgemäß befestigten Gleit­ lagerbuchse.a section through a trapezoidal connecting rod a slide fastened according to the invention bearing bush.

Das in der einzigen Figur in einem Teilschnitt dargestell­ te Pleuel 1 wird insbesondere bei einer Hubkolben-Brenn­ kraftmaschine - beispielsweise bei einer Dieselbrennkraft­ maschine - zur Anlenkung von Kolben an die Kurbelwelle verwendet. Dabei ist das Pleuel 1 an dem kleinen Pleuel­ auge trapezförmig in der Form ausgebildet, daß die Seiten­ flächen des Pleuelauges zum kolbenseitigen Ende des Pleuels hin abgeschrägt sind. Dies hat den Vorteil, daß die Druck aufnehmende Lagerfläche des kleinen Pleuelauges 2 im wesentlichen unverändert, dagegen die Zugkraft auf­ nehmende Lagerfläche deutlich verkleinert wird. Dadurch ergeben sich sowohl hinsichtlich des Gewichts der bewegten Massen Vorteile, als auch eine Verbesserung der Kraftüber­ tragung der von dem Kolben auf das Pleuel 1 wirkenden Kräfte.The connecting rod 1 shown in the single figure in a partial section is used in particular in a reciprocating piston internal combustion engine - for example in a diesel internal combustion engine - for articulating pistons to the crankshaft. The connecting rod 1 is trapezoidal on the small connecting rod eye in the form that the side surfaces of the connecting rod eye are chamfered towards the piston-side end of the connecting rod. This has the advantage that the pressure-absorbing bearing surface of the small connecting rod eye 2 is essentially unchanged, whereas the tensile force on the bearing surface taking it is significantly reduced. This results in both in terms of the weight of the moving masses advantages, as well as an improvement in the power transmission of the forces acting on the connecting rod 1 from the piston.

In das kleine Pleuelauge 2 ist eine Gleitlagerbuchse 3 eingesetzt und durch Verkleben des Außenumfangs der Gleit­ lagerbuchse mit dem Innenumfang des Pleuelauges 2 verbun­ den. Dabei übernimmt der Kleber sowohl die Fixierung der Gleitlagerbuchse 3 in dem Pleuelauge 2 als auch die Über­ nahme des Traganteils der zu übertragenden Kräfte. Zu be­ merken ist, daß bei dem erfindungsgemäß ausgestalteten Pleuel, dessen Außenkonturen im Bereich des kleinen Pleuelauges 2 sämtlich als Rohkontur dargestellt sein können, und der Innenumfang des kleinen Pleuelauges 2 nicht fein bearbeitet werden muß, so daß sich insgesamt ein erheblich geringerer Arbeitsaufwand gegenüber einem Pleuel mit einer herkömmlich eingepreßten Gleitlagerbuchse 3 ergibt.In the small connecting rod eye 2 , a plain bearing bush 3 is inserted and by gluing the outer circumference of the plain bearing bush to the inner circumference of the connecting rod eye 2 . The adhesive takes over both the fixation of the plain bearing bush 3 in the connecting rod eye 2 and the takeover of the load share of the forces to be transmitted. It should be noted that in the connecting rod designed according to the invention, the outer contours of which in the area of the small connecting rod eye 2 can all be shown as a raw contour, and the inner circumference of the small connecting rod eye 2 does not have to be finely machined, so that overall a considerably lower workload compared to one Connecting rod with a conventionally pressed-in plain bearing bush 3 results.
