  • Publication number: 20220364634
    Abstract: A transmission may include an input shaft, a first output shaft, a second output shaft, a first planetary gearset, and a second planetary gearset connected to the first planetary gearset. The input shaft, the first and second output shafts, and the planetary gearsets may be arranged such that a torque input via the input shaft is converted and distributed in a defined ratio to the two output shafts, and the formation of a combined torque is prevented. At least one element of the first planetary gearset may be connected to at least one element of the second planetary gearset with a shaft for conjoint rotation, and at least one element of the second planetary gearset may be fixed in place on a non-rotating component. A connector may be arranged and configured to passively, and therefore without a control unit and without an actuator, connect the first output shaft and second output shaft.

  • Publication number: 20220356936
    Abstract: 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.
