Abstract

An integrated planetary gearing system includes a reduction gear and a spur gear differential. First planets are arranged in a first planet plane. Second planets are arranged in a second planet plane. A planetary carrier includes a first carrier wall section, a second carrier wall section, and a third carrier wall section. The first and the second carrier wall section are spaced apart from one another axially and are formed by a base part. The third carrier wall section is formed by a cover element which is attached to the base part. The second carrier wall section carries a plurality of pockets, each receiving a planet of the second toothing plane. The cover element is attached to cover seat faces of the pocket bottoms, which cover seat faces in each case face away from the pocket interior.
