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. Optionally, the input shaft is connected to a first element of the first planetary gearset for conjoint rotation, the first output shaft is connected to a second element of the first planetary gearset for conjoint rotation, and the second output shaft is connected to a third element of the second planetary gearset for conjoint rotation. A third element of the first planetary gearset may be connected to a first element of the second planetary gearset via a shaft for conjoint rotation, and a second element of the second planetary gearset may be fixed in place on a non-rotating component.

Dependent claims

A transmission comprising

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, wherein the planetary gearsets, wherein
the input shaft is connected to a first element of the first planetary gearset for conjoint rotation,
the first output shaft is connected to a second element of the first planetary gearset for conjoint rotation,
the second output shaft is connected to a third element of the second planetary gearset for conjoint rotation,
a third element of the first planetary gearset is connected to a first element of the second planetary gearset via a shaft for conjoint rotation, and
a second element of the second planetary gearset is fixed in place on a non-rotating component,
wherein a shifting element is disposed and designed to connect the two output shafts to one another in a torque-transferring manner, such that a torque to one of the two output shafts is conducted radially outside the shifting element.
