  • Publication number: 20240116346
    Abstract: The disclosure relates to a transmission comprising an input shaft, a first output shaft, a second output shaft, a first planetary gear set, and a second planetary gear set which is connected to the first planetary gear set. Each of the planetary gear sets comprises multiple elements. The input shaft, the two output shafts, the planetary gear sets, as well as the elements thereof are arranged and designed such that—a torque introduced via the input shaft is converted and is distributed to the two output shafts in a defined ratio, and the development of a sum torque is prevented. At least one element of the first planetary gear set is rotationally fixed to another element of the second planetary gear set. Another element of the second planetary gear set is secured to a rotationally fixed component.

  • Patent number: 11815169
    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.

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.
