Abstract
Description
Die Erfindung betrifft eine Ausgleichswelle mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The invention relates to a balance shaft with the features of the preamble of claim 1.
Sie geht von der deutschen Patentschrift
Nachteilig an einer derartigen, gattungsgemäßen Ausgleichswelle sind ihr relativ hohes Gewicht und die damit verbundenen relativ hohen Herstellkosten.A disadvantage of such a generic balance shaft are their relatively high weight and the associated relatively high production costs.
Aus diesem Grund liegt der vorliegenden Erfindung die Aufgabe zugrunde, bei weniger Materialeinsatz und praktisch gleicher Unwucht ein besseres Unwucht/Gewichtsverhältnis darzustellen.For this reason, the present invention has the object, with less material use and virtually the same imbalance to represent a better imbalance / weight ratio.
Diese Aufgabe wird durch das Merkmal im kennzeichnenden Teil des Patentanspruchs 1 gelöst.This object is achieved by the feature in the characterizing part of patent claim 1.
Durch die erfindungsgemäße Ausgestaltung ist in vorteilhafter Weise eine Gewichts- und Kosteneinsparung von bis zu 15% möglich. Weiter wird das Massenträgheitsmoment um die Rotationsachse reduziert, woraus eine verbesserte Antriebsakustik resultiert.The embodiment of the invention is advantageously a weight and cost savings of up to 15% possible. Furthermore, the mass moment of inertia about the axis of rotation is reduced, resulting in improved drive acoustics.
Mit den Ausgestaltungen gemäß der Patentansprüche 2 und 3 verbessert sich der erfindungsgemäße Effekt nochmals um bis zu 15%.With the embodiments according to
Mit der Ausgestaltung gemäß Patentanspruch 4 werden die Biegemomente innerhalb der Lagerstellen deutlich reduziert.With the embodiment according to
Die Ausführung gemäß Patentanspruch 5 ist eine besonders bevorzugte Ausführungsform.The embodiment according to
Aufgrund der geringen Biegemomente kann die Ausgleichswelle gemäß Patentanspruch 6 wälzgelagert, wie z. B. nadelgelagert werden.Due to the low bending moments, the balance shaft according to claim 6 roller bearings, such. B. needle bearing.
Im Folgenden ist die Erfindung anhand eines besonders bevorzugten Ausführungsbeispiels in drei Figuren näher erläutert.In the following, the invention is explained in more detail with reference to a particularly preferred embodiment in three figures.
