Aufgabe der Erfindung ist es, einen kostengünstigen und hoch belastbaren Planetenträger zu schaffen.task The invention is a cost-effective and highly resilient planet carrier to accomplish.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen von Patentanspruch 1 gelöst.These Task is according to the invention with the Characteristics of claim 1 solved.
Gemäß einem Vorteil der Erfindung sind die beiden Wangen zur Aufnahme der Achse, welche die Planetenräder trägt, einstückig hergestellt. Damit ist dieser Teil des Planetenträgers hoch belastbar. Zwischen der ersten Wange und einer Welle ist hingegen eine Verbindung vorgesehen. Im Bereich dieser Verbindung treten nur relativ geringe Spannungen auf, so dass auch die Verbindung nur gering belastet wird. Aus der geringen Belastung der Verbindung ergibt sich eine hohe Lebensdauer. Die Verbindung kann als Schweißverbindung oder als formschlüssig drehfeste Verbindung ausgeführt sein. Eine solche formschlüssig drehfeste Verbindung ist die Steckverbindung.According to one Advantage of the invention are the two cheeks for receiving the axis, which the planet wheels wearing, one piece produced. So this part of the planet carrier is high resilient. On the other hand, there is one between the first cheek and a wave Connection provided. In the area of this connection occur only relatively low voltages, so that the connection is only slightly loaded becomes. From the low load of the compound results in a long life span. The compound can be used as a welded connection or as a positive non-rotatable Connection performed be. Such a positive fit non-rotatable connection is the connector.
Wird das einstückige Bauteil aus Wangen und Stegen als Gussbauteil ausgeführt, so besteht ein großer geometrischer Gestaltungsspielraum. Damit ist es möglich, eine leichtgewichtige Bauform zu schaffen.Becomes the one-piece Component made of cheeks and webs designed as cast component, see above there is a big one geometric design travel. With that it is possible to have one to create a lightweight design.
Die Verbindungsstelle zwischen der Welle und der ersten Wange ist dabei besonders leicht zugänglich, so dass beim Schweißen Schweißnähte mit einer besonders hohen Güte hergestellt werden können. Damit ist es auch möglich, Planetenträger für besonders hohe Drehmomentschwankungen herzustellen.The Joint between the shaft and the first cheek is included particularly easy to access, so that when welding Welds with a especially high quality can be produced. This is also possible planet carrier for special produce high torque fluctuations.
Weitere Vorteile der Erfindung gehen aus den weiteren Patentansprüchen, der Beschreibung und der Zeichnung vor.Further Advantages of the invention will become apparent from the other claims, the Description and the drawing above.
Die Erfindung ist nachfolgend anhand eines Ausführungsbeispiels erläutert.The The invention is explained below with reference to an embodiment.
Dabei zeigen:there demonstrate:
Ebenso kann das Planetengetriebe einem Längsverteilergetriebe eines Allradfahrzeugs zugehörig sein.As well the planetary gear can be a Längsverteilergetriebe a 4WD vehicle associated be.

This includes in particular friction welding, electron beam welding and the laser welding.
Bei den beschriebenen Ausführungsformen handelt es sich nur um beispielhafte Ausgestaltungen. Eine Kombination der beschriebenen Merkmale für unterschiedliche Ausführungsformen ist ebenfalls möglich. Weitere, insbesondere nicht beschriebene Merkmale der zur Erfindung gehörenden Vorrichtungsteile, sind den in den Zeichnungen dargestellten Geometrien der Vorrichtungsteile zu entnehmen.at the described embodiments is they are only exemplary embodiments. A combination of described features for different embodiments is also possible. Further, in particular not described features of the invention belonging Device parts are the geometries shown in the drawings to remove the device parts.
