Abstract
A speed-changing and differential transmission includes a speed-changing section and a differential section. The speed-changing section has an input stage and a load stage. The sun wheel of the load stage can be operatively connected to at least one planet wheel of the input stage via a planet carrier. At least one planet wheel of the load stage can be operatively connected to the annulus of the input stage via a planet carrier. One of these operative connections is configured as a selectable connection and the other is configured as a fixed connection such that through use of a coupling device, the annulus of the input stage can be operatively coupled to the planet carrier of the load stage, or the sun wheel of the load stage can be operatively coupled to the planet carrier of the input stage.
