Bearing arrangement for a stepped planetary gear, and epicyclic gearing equipped therewith for a motor vehicle drive unit

An epicyclic gearing arrangement for a motor vehicle drive unit, comprising:

• a first sun gear;
• a second sun gear;
• a planet carrier;
• a planet arrangement, comprising a first planet and a second planet which engage the first and second sun gears, respectively, and engage each other such that the first and second sun gears are coupled with each other;
• a stepped planetary gear comprising a first toothing section and a second toothing section;
• a ring gear engaging the first toothing section of the stepped planetary gear;
• a third gear engaging the second toothing section of the stepped planetary gear;
• a bearing arrangement that supports the stepped planetary gear in the planetary gear carrier, comprising:
• a planetary gear journal on which the first toothing segment and the second toothing segment are located, having a first bearing section and a second bearing section, the first bearing section is located in an intermediate area between the first and the second toothing sections, and the second bearing section extends from a side of the first toothing section facing away from the second toothing section;
• and
• a first roller bearing provided as a cylindrical roller bearing arranged in an area of the first bearing section, the cylindrical roller bearing including cylindrical rollers that roll on a running surface of the planetary gear journal, and a first outer ring which rests in a first side part of the planet carrier.
