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).

摘要： A multi-speed transmission (9) for a rail vehicle. The multi-speed transmission (9) has at least one transmission input (AN), at least one transmission output (AB), at least one planetary gearset (PR1, PR2), at least one shifting element (SE1, SE2) and a housing (G). The planetary gearset (PR1, PR2) has a sun gear (S1, S2), at least one planetary carrier (PT1, PT2) with planetary gearwheels, and a ring gear (H1, H2), and rotational movement from a drive element (8) is introduced into the multi-speed transmission (9). By actuating the at least one shifting element (SE1, SE2), at least two different transmission ratios can be obtained between the transmission input (AN) and the transmission output (AB).

摘要： A gear unit for a powertrain of a motor vehicle includes a drive shaft, a driven shaft, first and second planetary gearsets and first and second shifting elements. The first shifting element drivingly connects the drive shaft to an input of the first planetary gearset, and the second shifting element drivingly connects the drive shaft to an input of the second planetary gearset. An output element of the second planetary gearset is connected to the input of the first planetary gearset to be fixed with respect to rotation relative to it, and an output of the first planetary gearset is at least indirectly drivingly connected to the driven shaft. A shared element is fixed with respect to relative rotation and, with an inner toothing, forms a ring gear of the first planetary gearset and, with an outer toothing, forms a sun gear of the second planetary gearset

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 continuously variable power-split transmission having a planetary gear mechanism arrangement. The planetary gear mechanism arrangement has three planetary gear sets, an input shaft and three output shafts. Furthermore, the transmission has a change-speed gearbox connected to the output shafts, a reverse gear mechanism and a variator. Each of the three planetary gear sets is assigned a respective output shaft. The input shaft is operatively connected in each of the three planetary gear sets via a respective gearwheel pairing to a respective output shaft. The transmission can be shifted by the change-speed gearbox and the reverse gear mechanism into at least eight driving ranges. The variator varies a transmission ratio of the transmission within the driving ranges in a continuously variable manner. The variator is continuously operatively connected to a single one of the three planetary gear sets.
