1. A transmission comprising:
an input shaft,
a first output shaft,
a second output shaft,
a first planetary gearset, the first planetary gearset comprising a first element, a second element and a third element, and
a second planetary gearset connected to the first planetary gearset, the second planetary gearset comprising a first element, a second element and a third element,
wherein the input shaft, the first and second output shafts, and the planetary gearsets are 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,
wherein at least one element of the first planetary gearset is connected to at least one element of the second planetary gearset with a shaft for conjoint rotation, and
wherein at least one element of the second planetary gearset is fixed in place on a non-rotating component, and
wherein a connector is arranged and configured to passively connect the first output shaft and second output shaft such that a torque can be transferred between the first output shaft and the second output shaft, wherein the first planetary gearset and the second planetary gearset each have a helical gearing,
wherein a force flow circuit of axial forces through the helical gearing is closed via the connector in at least one of a forward traction mode or a reverse pushing mode of the transmission.
