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.

Abstract: A transmission and differential gearing with a housing, with an input shaft and two output shafts arranged coaxially with respect to the input shaft, wherein a transmission section and a differential section are provided, wherein the transmission section has two planet stages, namely an input stage and a load stage, wherein the sun wheel of the input stage is actively connected to the input shaft, wherein the load stage has a ring gear fixed to the housing, and the sun wheel of the load stage can be or is actively connected via a web to at least one planet wheel of the input stage, and wherein at least one planet wheel of the load stage is actively connected via a web to an input shaft of the differential section.

Abstract: A friction roller planetary gearing includes a first and a second sun which are axially displaceable with respect to one another and at least one of the suns is connected for conjoint rotation to a sun shaft. Stepped planets roll on the suns, on a first annulus and on a second annulus. The suns, the annuluses and the stepped planets are configured as friction rings. The second annulus is axially displaceable relative to the first annulus. A first torque-dependent axial displacement device controls a contact pressure between the suns and contact surfaces of the planets by using a torque-dependent axial displacement of at least one of the suns. A second torque-dependent axial displacement device controls a contact pressure between the annuluses and contact surfaces of the planets by using a torque-dependent axial displacement of at least one of the annuluses.
