Abstract

A transmission and differential gearing includes a transmission section and a differential section. The transmission section has an input stage and a load stage. The sun gear of the input stage is connected or coupleable to an input shaft. The ring gear of the bad stage is fixed relative to the housing. The sun gear of the bad stage is connected to the carrier of the input stage. The carrier of the load stage is connected to the ring gear of the input stage. The differential section is a spur gear differential configured as a planetary gear set. The ring gear of the planetary gear set is connected to the carrier of the load stage. The carrier of the planetary gear set and the sun gear of the planetary gear set are connected to a respective one of two output shafts. A motor and gearing unit is also provided.
