Description

Die bekannten Pleuellagerschalen bestehen im allgemeinen aus einem Lagerschalenkörper aus Stahl, welcher innen und außen mit gleitfähigem Werkstoff ausgekleidet ist.The known connecting rod bearing shells generally consist of one Bearing shell body made of steel, which inside and outside with sliding material is lined.

Die Herstellung solcher Pleuellagerschalen bereitet jedoch häufig Schwierigkeiten, «eil das Auskleiden beider Laufflächen des im allgemeinen dünnwandigen Lagerschalenkörpers mit Lagermetall zu gleicher Zeit erfolgen muß, wobei bei der Verwendung eines Lagermetalls mit hoher Gießtemperatur außerdem die Gefahr besteht, daß sich im Lagerschalenkörper Haarrisse bilden, «-elche sich der Prüfung entziehen, beim Dauerbetrieb der Schale jedoch zum Bruch führen können.The production of such connecting rod bearing shells, however, often prepares Difficulties in lining both treads of the generally thin-walled Bearing shell body with bearing metal must be done at the same time, with the Use of a bearing metal with a high casting temperature also runs the risk of that hairline cracks form in the bearing shell body, "-which evade the test, However, if the shell is used continuously, it can break.

Außerdem ist das Einpassen einer Pleuellagerschale mit doppelter Lautfläche auf die innen lagernde Welle und auf die außen gleitenden Pleuel schwierig und zeitraubend.In addition, the fitting of a connecting rod bearing shell with double the sound surface difficult and time-consuming on the shaft on the inside and on the connecting rods sliding on the outside.

Diese Nachteile vermeidet die Erfindung dadurch, daß von den beiden Laufflächen der Pleuellagerschale eine, vorzugsweise die äußere, durch eine gehärtete Schicht des Lagerschalenkörpers gebildet wird, während die andere Lauffläche in bekannter Weise einem Lagermetallausguß angehört.The invention avoids these disadvantages in that of the two Running surfaces of the connecting rod bearing shell one, preferably the outer one, through a hardened one Layer of the bearing shell body is formed, while the other tread in is known to belong to a bearing metal spout.

Die beiden Laufflächen der Pleuellagerschale können in zeitlich vollständig getrennter Aufeinanderfolge hergestellt werden. Besonders zweckmäßig ist die Einsatzhärtung der äußeren Lauffläche und der Ausguß der inneren Lauffläche mit einem Lagermetall. In der Zeichnung ist ein Ausführungsbeispiel der Pleuellagerschale gemäß der Erfindung dargestellt.The two running surfaces of the connecting rod bearing shell can be completely timed be made in separate succession. Case hardening is particularly useful the outer running surface and the spout of the inner running surface with a bearing metal. In the drawing is an embodiment of the connecting rod bearing shell according to the invention shown.

Die Lagerschale 2 ist in die Gabel eines Hauptpleuels r fest eingesetzt und auf der inneren Gleitfläche für die Kurbelwelle d. mit einem Ausguß 3 eines Lagermetalls versehen. Das Nebenpleuel 5 gleitet außen auf der dort gehärteten Lagerschale 2, deren Härtung es auch ermöglicht, das Nebenpleuel5 mittels :Tadeln 6 zu lagern.The bearing shell 2 is firmly inserted into the fork of a main connecting rod r and on the inner sliding surface for the crankshaft d. with a spout 3 one Bearing metal provided. The secondary connecting rod 5 slides outside on the bearing shell hardened there 2, the hardening of which also makes it possible to store the secondary connecting rod 5 by means of: censures 6.

PATENTANSPRUCH: Pleuellagerschale mit äußerer und innerer Lauffläche, insbesondere für die Rollenlagerung der Pleuel einer Brennkraftmaschine mit V-förmig angeordneten Zylindern, dadurch gekennzeichnet, daß von den beiden Laufflächen der Pleuellagerschale (2) eine, vorzugsweise die äußere, durch eine gehärtete Schicht des Lagerschalenkörpers gebildet wird, während die andere Lauffläche in bekannter Weise einem Lagermetallguß (3) angehört. Zur Abgrenzung des Erfindungsgegenstands vom Stand der Technik sind im Erteilungsverfahren folgende Druckschriften in Betracht gezogen worden: Französische Patentschrift Nr. 495 -139 britische Patentschriften Nr. 129 248. 229 336, 355 .150, 470 539.Claim: connecting rod bearing shell with outer and inner running surface, in particular for the roller bearing of the connecting rod of an internal combustion engine with V-shaped cylinders, characterized in that one of the two running surfaces of the connecting rod bearing shell (2), preferably the outer one, is formed by a hardened layer of the bearing shell body is, while the other running surface belongs in a known manner to a cast metal bearing (3). To distinguish the subject matter of the invention from the state of the art, the following documents were considered in the grant procedure: French patent specification No. 495-139 British patent specification No. 129 248, 229 336, 355 .150, 4 70 539.
