    摘要： A transmission having input and output shafts and planetary gear sets. Each planetary gear set has multiple elements. The input and output shafts and planetary gear sets are designed so torque introduced via the input shaft is distributed to the output shafts in a defined ratio and a sum torque is prevented. An element of a first planetary gear set is rotationally fixed to another element of a second planetary gear set and another element of the second planetary gear set is secured to a rotationally fixed component. A torque vectoring superposition unit has an epicyclic gearing and two switching elements. The epicyclic gearing has four connection shafts. A first connection shaft is rotationally fixed to the linking shaft. A second connection shaft is rotationally fixed to an output shaft of the first planetary gear set. The switching elements secure a third and fourth connection shaft to a fixed component.

    摘要： A transmission, preferably for driving a motor vehicle, includes a multi-gear main transmission and a range group, that is connected downstream from the main transmission and comprises an input shaft and an epicyclic gear system. The epicyclic gear system comprises elements in the form at least of a central gearwheel and a planetary carrier. Furthermore, the transmission comprises a first connection for driving one of the elements of the epicyclic gear system by way of the input shaft of the range group and a variator, as well as a second connection that can be engaged with the first connection for driving a further element of the elements of the epicyclic gear system. When the second connection is engaged, the input shaft of the range group drives the variator and a drive output of the variator drives the further element of the epicyclic gear system.

    摘要： A transmission with a differential locking unit which comprises an input shaft (10), first and second output shafts (11, 12), and first and second planetary gear sets (P1, P2). Torque introduced, via the input shaft (10), is converted and distributed to the two output shafts (11, 12) in a defined ratio, and development of a sum torque is prevented. The differential locking unit comprises an epicyclic gearing (P3) as well as a switching element (B 1). The epicyclic gearing (P3) has at least three connection shafts (3), a first connection shaft (WI) is rotationally fixed to a linking shaft (3), a second connection shaft (W2) is rotationally fixed to the second element (E21) of the first planetary gear set (PI), which is rotationally fixed to the first output shaft (11). A third connection shaft (W3) can be secured to a rotationally fixed component (GG) by the switching element (B 1).

    摘要： A transmission having an input and first and second output shafts and first and second planetary gear sets. Torque introduced via the input shaft is distributed to the two output shafts in a defined ratio. An element of the first planetary gear set is connected to another element of the second planetary gear set and an element of the second planetary gear set is secured to a rotationally fixed component. A torque vectoring superposition unit has a third planetary gear set. A first element of the third planetary gear set is rotationally fixed to a linking shaft. A second element of the third planetary gear set is connected to a machine rotor. A third element of the third planetary gear set is rotationally fixed to an element of the second planetary gear set, which is fixed to the first output shaft.
