Abstract
Nockenwelle, insbesondere gebaute Nockenwelle für eine Brennkraftmaschine, mit einer Außenwelle und einer innerhalb der Außenwelle angeordneten Innenwelle, auf welchen jeweils Einlass- und Auslassnocken angeordnet sind, wobei die auf der Innenwelle angeordneten Nocken durch ein Mitnahmeglied mit der Innenwelle verbunden sind, und wobei die Einlassnocken über eine Phasenverstelleinrichtung gegenüber den Auslassnocken verstellbar sind, wobei die mit der Innenwelle über das Mitnahmeglied verbundenen Nocken jeweils einen in Axialrichtung der Nocken nach außen stehenden zylindrischen Bereich aufweisen, wobei in dem zylindrischen Bereich eine Ausnehmung vorgesehen ist, in welcher das Mitnahmeglied angeordnet ist, und wobei die Innenwelle hohl mit einer zentralen Bohrung ausgebildet ist, dadurch gekennzeichnet, dass die zentrale Bohrung (10) der Innenwelle (3) zur Ölversorgung von Nockenwellenlagern (4), in welchen die Außenwelle (2) aufgenommen ist, und der Phasenverstelleinrichtung (11) dient, wobei die Außenwelle (2) und die Innenwelle (3) jeweils mit einer Öffnung (12) für die Ölzufuhr versehen sind, und wobei im Bereich der...Camshaft, in particular built camshaft for an internal combustion engine, with an outside wave and one inside the outer shaft arranged inner shaft, on each of which intake and exhaust cam are arranged, wherein arranged on the inner shaft cam are connected by a driving member with the inner shaft, and wherein the intake cams over one Phase adjustment opposite the exhaust cams are adjustable, with the inner shaft via the driving member connected cams each one in the axial direction of the cam Outside standing cylindrical portion, wherein in the cylindrical Area a recess is provided, in which the driving member is arranged, and wherein the inner shaft hollow with a central Bore is formed, characterized in that the central Bore (10) of the inner shaft (3) for oil supply of camshaft bearings (4), in which the outer shaft (2) is received, and the phase adjuster (11) is used, being the outer shaft (2) and the inner shaft (3) each with an opening (12) for the oil supply are provided, and being in the range of ...
Description
Die Erfindung betrifft eine Nockenwelle, insbesondere eine gebaute Nockenwelle für eine Brennkraftmaschine, nach der im Oberbegriff des Anspruchs 1 näher definierten Art.The The invention relates to a camshaft, in particular a built camshaft for one Internal combustion engine, according to which further defined in the preamble of claim 1 Art.

Es ist Aufgabe der Erfindung, dafür zu sorgen, dass bei einer Nockenwelle für eine Brennkraftmaschine, bei der die Einlassnocken gegenüber den Auslassnocken verstellt werden können, die Nockenwellenlager und die Verstelleinrichtung in einfacher und zuverlässiger Weise mit Öl versorgt werden können, und zwar ohne dass dabei die Tribologie zwischen den Nocken und den Reibpartnern der Nocken gestört wird.It is the object of the invention, therefore to ensure that in a camshaft for an internal combustion engine, at the inlet cam opposite the exhaust cam can be adjusted, the camshaft bearing and the adjustment in a simple and reliable manner with oil can be supplied and without doing the tribology between the cams and Disturbed the friction partners of the cam becomes.
Erfindungsgemäß wird diese Aufgabe durch die im kennzeichnenden Teil des Anspruches 1 genannten Merkmale gelöst.According to the invention this Task by the mentioned in the characterizing part of claim 1 Characteristics solved.
Mit der erfindungsgemäßen Nockenwelle ist es möglich Einlassnocken und Auslassnocken zueinander zu verstellen und das zur Schmierung der Nockenwellenlager und der zur Verstellung der Nocken erforderlichen Phasenverstelleinrichtung benötigte Öl in einfacher Weise sehr gezielt zuzuführen.With the camshaft according to the invention Is it possible Adjacent intake cam and exhaust cam to each other and the for lubrication of the camshaft bearing and for adjusting the Cam required Phasenverstelleinrichtung required oil in a simple To supply very targeted way.
Die Innenwelle ist im Bereich der Ausnehmung mit Dichtungseinrichtungen versehen, die vorteilhafterweise einen Ölaustritt zwischen der Innenwelle und der Außenwelle sowie dem Zylinderstift verhindern.The Inner shaft is in the area of the recess with sealing devices provided, which advantageously an oil outlet between the inner shaft and the outside wave and prevent the cylinder pin.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und dem nachfolgend der Zeichnung prinzipmäßig beschriebenen Ausführungsbeispiel.Advantageous embodiments and developments of the invention will become apparent from the Unteran spells and the embodiment of the drawing described in principle below.
