Abstract
Description
Die Erfindung betrifft einen Lagerdeckel zur Festlegung einer Welle in einem Gehäuse, insbesondere einer Welle einer Kraftfahrzeug-Brennkraftmaschine, wie Nocken-, Kurbel- oder Ausgleichswelle in einem Kurbelgehäuse oder Zylinderkopf, wobei der Lagerdeckel in Wellenachsrichtung eine vorbestimmte Mindest-Breite und senkrecht dazu eine vorbestimmte Mindest-Dicke aufweist.The The invention relates to a bearing cap for fixing a shaft in a housing, in particular a shaft of a motor vehicle internal combustion engine, as cam, crankshaft or balance shaft in a crankcase or Cylinder head, wherein the bearing cap in Wellenachsrichtung a predetermined Minimum width and perpendicular to a predetermined minimum thickness having.
Bei Drehung der Welle nimmt der Lagerdeckel Kräfte auf. Zur Aufnahme dieser Kräfte weist der Lagerdeckel eine vorbestimmte Mindest-Breite und senkrecht dazu eine vorbestimmte Mindest-Dicke auf. Üblicherweise beträgt die Dicke des Lagerdeckels ca. 70–100% seiner Breite. Dabei ist die Breite derartiger Lagerdeckel gleich oder zumindest nur unwesentlich größer, als die Breite eines tragenden Bereichs des Lagerdeckels, der mit der Welle in korrespondiert.at Rotation of the shaft absorbs the bearing cap forces. To record this personnel the bearing cap has a predetermined minimum width and perpendicular to a predetermined minimum thickness. Usually the thickness is of the bearing cap approx. 70-100% its width. The width of such bearing cap is the same or at least only slightly larger than the width of a bearing Area of the bearing cap, which corresponds with the shaft in.
Die Dicke des Lagerdeckels ist gerade bei Kraftfahrzeug-Brennkraftmaschinen für die Bauhöhe oder Baubreite mitbestimmend. Zudem ist, insbesondere bei Brennkraftmaschinen mit einer Einrichtung zum Variieren der Ventilhubhöhe und Direkteinspritzung mit zentraler Injektorlage, der Bauraum oft stark begrenzt.The Thickness of the bearing cap is just in automotive internal combustion engines for the Height or Co-ordinate width. In addition, especially in internal combustion engines with a device for varying the valve lift height and direct injection with central injector, the space often limited.
Aufgabe der Erfindung ist es daher, einen eingangs genannten Lagerdeckel mit verringerter Dicke bereit zu stellen, sodass Bauraumprobleme vermieden werden. Dabei soll jedoch der Lagerdeckel auftretende Kräfte dennoch zuverlässig aufnehmen.task The invention is therefore an initially mentioned bearing cap to provide with reduced thickness, so space problems be avoided. However, the bearing cap should occur personnel nevertheless reliable take up.
Die Lösung der Aufgabe erfolgt mit einem Lagerdeckel mit den Merkmalen des Anspruchs 1, indem der Lagerdeckel eine reduzierte Mindest-Dicke und eine entsprechend erhöhte Mindest-Breite aufweist. Auf diese Weise kann der Lagerdeckel mit einer geringen Dicke ausgeführt werden, um Bauraumprobleme zu vermeiden und es können dennoch auftretende Kräfte zuverlässig aufgenommen werden.The solution The task is done with a bearing cap with the characteristics of Claim 1, by the bearing cap a reduced minimum thickness and a correspondingly increased Minimum width. In this way, the bearing cap with made of a small thickness be used to avoid space problems and it can still reliably occurring forces absorbed become.
Besonders zu bevorzugende Ausführungen und Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Especially to be preferred embodiments and Further developments of the invention are the subject of the dependent claims.
Vorzugsweise ist bei einem Lagerdeckel, der einen tragenden Bereich aufweist, die vorbestimmte Mindest-Breite größer, als die Breite des tragenden Bereichs. Der Lagerdeckel weist demnach in Wellenachsrichtung eine größere Breite auf, als sein tragender Bereich. Damit wird die Belastbarkeit des Lagerdeckels wesentlich erhöht, ohne den tragende Bereich und/oder die Dicke des Lagerdeckels zu vergrößern.Preferably is at a bearing cap, which has a bearing area, the predetermined minimum width greater than the width of the supporting area. The bearing cap accordingly has a larger width in the shaft axis direction on, as its carrying area. Thus the load capacity of the Bearing cap substantially increased, without the load-bearing area and / or the thickness of the bearing cap enlarge.
Als sehr zweckmäßig hat es sich erwiesen, wenn die vorbestimmte Mindest-Breite des Lagerdeckels wenigstens das 1,5-fache der Breite des tragende Bereichs beträgt.When very useful it turned out, if the predetermined minimum width of the bearing cap at least the 1.5 times the width of the load-bearing area.
Alternativ kann mit der erhöhten Mindest-Breite jedoch auch die Breite des tragenden Bereichs des Lagerdeckels erhöht werden.alternative can with the increased Minimum width but also the width of the supporting area of the Bearing cap increased become.
