A transmission device is proposed for distributing a drive torque to at least two output shafts (Ab, Ab), comprising a differential () that is permanently connected to the output shafts (Ab, Ab), wherein a double planetary gearset () is provided co-axially to the output (Ab) between the differential cage () of the differential () and the output (Ab) of one side, said planetary gearset comprising a first sun gear () and a second sun gear (), a first planetary range (), an intermediate planetary range (), and an internal gear (), herein the internal gear () is connected to the differential cage () and the planet carrier () of the planetary gearset () is connected to the output (Ab), wherein the first sun gear () meshes with the first planetary range () and can be coupled to the housing (G) by means of a brake () in order to shift the torque in one direction, and wherein the second sun gear () meshes with the intermediate planetary range () and can be coupled to the housing (G) by means of an additional brake () in order to shift the torque in the opposite direction.
