Abstract

The connecting rod bearing unit is for at least two connecting rods (6,8) on the crank journal (2) of a crankshaft (1), with a bearing shell (5) on the crank journal fixed to one of the connecting rods (6). The bearing shell is made as a separate component, and the second connecting rod (8) can rotate on it. The fixed connecting rod is a located fit on the bearing shell. There may be a lock (7) preventing rotation between the bearing shell and the first connecting rod.

Description

Die Erfindung betrifft eine Lagerung von mindestens zwei auf dem Hubzapfen einer Kurbelwelle parallel angeordneten Pleueln, insbesondere für Brennkraftmaschinen, mit den im Oberbegriff des Patentanspruches genannten Merkmalen.The invention relates to a storage of at least two on the crank pin Crankshaft connecting rods arranged in parallel, especially for internal combustion engines, with the features mentioned in the preamble of the claim.

Bei Verbrennungsmotoren, insbesondere bei V-Motoren, sind Pleuellagerungen mit zwei Pleueln auf einem Hubzapfen der Kurbelwelle allgemein vorbekannt. Vorbekannt sind durch die Schriften DRP 129 082 und 321 357 Pleuellagerungen, bei denen ein Pleuel mit einer breiten Lagerbuchse als ein Teil ausgeführt ist, wobei das daneben befindliche oder übergreifende Pleuel schwenkbar auf einem über­ stehenden Teil der gemeinsamen Lagerbuchse gelagert ist.In internal combustion engines, especially in V engines, connecting rod bearings are included two connecting rods on a crank pin of the crankshaft generally known. The DRP 129 082 and 321 357 connecting rod bearings are previously known, in which a connecting rod with a wide bearing bush is designed as one part, wherein the connecting rod located next to or overlapping can be swiveled on an over standing part of the common bearing bush is stored.

Nachteilig bei diesen bekannten Pleuellagerungen ist die aufwendige Herstellung des mit der überstehenden Lagerbuchse versehenen Pleueln.A disadvantage of these known connecting rod bearings is the complex production the connecting rod with the protruding bearing bush.

Vorbekannt ist durch die Schrift DE-OS 37 44 197 eine Pleuellagerung, bei der auf den geteilten Hubzapfen einer gebauten Kurbelwelle jeweils ein einziger ungeteilter Lagerring vorgesehen ist, der sich über die gesamte Breite des Hubzapfens erstreckt und auf dem mehrere Pleueln gelagert sind. Der Lagerring ist relativ zum Hubzapfen und zu den Pleueln schwimmend verdrehbar angeordnet.A connecting rod bearing is known from DE-OS 37 44 197 the split crank pin of a built crankshaft is a single undivided one Bearing ring is provided, which extends over the entire width of the crank pin and on which several connecting rods are stored. The bearing ring is relative to the crank pin and arranged to be rotatable in relation to the connecting rods.

Die hohe relative Gleitgeschwindigkeit tritt zwischen Hubzapfen und Lagerring auf, während die einzelnen Pleueln nur in unterschiedlichen Umfangsbereichen des La­ gerringes schwenken.The high relative sliding speed occurs between the crank pin and the bearing ring, while the individual connecting rods only in different circumferential areas of the La small swivel.

Die beschriebene Anordnung erfordert nur wenig axialen Bauraum und sichert auf­ grund der zwangsläufigen Relativverdrehung zwischen Lagerring und den Pleueln eine gleichmäßige, gesamtflächige Belastung des Hubzapfens.The arrangement described requires little axial space and secures due to the inevitable relative rotation between the bearing ring and the connecting rods uniform, total load on the crank pin.

Es ist Aufgabe der Erfindung, die gattungsgemäße Pleuellagerung hinsichtlich des vorhandenen Bauraumes und der Standfestigkeit so zu gestalten, daß eine höhere Lagertragfähigkeit bei einfacher Herstellung und Montage erreicht wird.It is an object of the invention, the generic connecting rod bearing in terms of existing space and stability so that a higher Bearing capacity is achieved with simple manufacture and assembly.

Die Lösung dieser Aufgabe gelingt mit den Merkmalen des Patentanspruchs 1. Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus dem nachfolgenden Ausführungsbeispiel und den abhängigen Ansprüchen.This object is achieved with the features of patent claim 1. Advantageous embodiments of the invention result from the following Embodiment and the dependent claims.

Die Zeichnung zeigt einen Abschnitt einer Kurbelwelle 1 mit einem Hubzapfen 2 und Lagerzapfen 3, 4, über welche die Kurbelwelle 1 in einem nicht dargestellten Kurbel­ gehäuse drehbar aufgenommen ist.The drawing shows a section of a crankshaft 1 with a crank pin 2 and bearing pin 3 , 4 , via which the crankshaft 1 is rotatably received in a crankcase, not shown.

Auf dem Hubzapfen 2 sitzt drehbar eine Lagerbuchse 5, auf der ein Pleuel 6 über einen entsprechenden Paßsitz mit Verdrehsicherung 7 zur Lagerbuchse 5 fest ge­ lagert ist. Ein weiteres Pleuel 8 ist schwenkbar mittels Spielsitz auf der gemeinsamen neben dem Pleuel 6 überstehenden Lagerbuchse 5 gelagert.On the crank pin 2 , a bearing bush 5 is rotatably seated, on which a connecting rod 6 is mounted via a corresponding fit with anti-rotation 7 to the bearing bush 5 . Another connecting rod 8 is pivotally mounted by means of a play seat on the common bearing bush 5 which projects beyond the connecting rod 6 .

Die Schmierung der schwenkbaren Pleuellagerung erfolgt mittels Spritzöl oder durch Drucköl über den Hubzapfen 2 und Ölbohrungen 9, 10. Je nach Erfordernis kann die Lagerbuchse 5 mit besonderen Lagerwerkstoffen oder Flächenbehandlungen an den gleitenden Oberflächen der Lagerbuchse 5 oder des Pleuelauges ausgeführt wer­ den.The swiveling connecting rod bearing is lubricated by means of spray oil or pressure oil via the crank pin 2 and oil holes 9 , 10. Depending on the requirements, the bearing bush 5 can be carried out with special bearing materials or surface treatments on the sliding surfaces of the bearing bush 5 or the connecting rod eye.

Die Lagerbuchse 5 ist bevorzugt als Stahllagerbuchse ausgeführt und ist zumindest unter dem schwenkbaren Pleuel 8 mit einem gesonderten Lagerwerkstoff beschich­ tet. Dieser weist insbesondere Aluminium und/oder Zinn und/oder Zink auf. Für eine vereinfachte Fertigung während der Beschichtung kann die gesamte, den Pleueln 6 und 8 zugeordnete Oberfläche derartig beschichtet sein.The bearing bush 5 is preferably designed as a steel bearing bush and is coated at least under the pivotable connecting rod 8 with a separate bearing material. This has in particular aluminum and / or tin and / or zinc. The entire surface associated with the connecting rods 6 and 8 can be coated in this way for simplified production during the coating.

Die Lagerbuchse 5 kann innen, auf der gesamten, dem Hubzapfen 2 zugewandten Oberfläche mit einem identischen Lagerwerkstoff beschichtet sein.The bearing bush 5 can be coated on the inside with an identical bearing material over the entire surface facing the crank pin 2 .

Die Lagerbuchse 5 und die unteren Lager der Pleueln 6 und 8 können bei gebau­ ten Kurbelwellen ungeteilt und bei einstückigen Kurbelwellen in bekannter Weise in deren Längsrichtung geteilt ausgeführt sein. The bearing bush 5 and the lower bearing of the connecting rods 6 and 8 can be undivided in the case of crankshafts and can be made in one piece in the longitudinal direction in a known manner in the case of integral crankshafts.

Die Vorzüge der Erfindung bestehen darin, daß zwei schmale Pleueln auf einem Hubzapfen arbeiten und nur eine gemeinsame, separate Lagerbuchse mit entspre­ chend hoher Tragfähigkeit auf dem Hubzapfen eingesetzt wird, die einzeln bearbeitet werden kann.The advantages of the invention are that two narrow connecting rods on one Crank pins work and only one common, separate bearing bush with high load capacity is used on the crank pin, which is machined individually can be.
