Abstract
A planetary transmission for a vehicle, comprising a planet carrier, on which at least one planet wheel is mounted, a hub arranged for a vehicle wheel and connected to the planet carrier, and a static housing which is connected to the vehicle and in which the hub is mounted. A friction brake is arranged at an outer periphery of the planet carrier and is intended to brake the rotation of the planet carrier in relation to the static housing. The hub and the planet carrier are interconnected by a splined connection. According to an embodiment, an outer gear ring is arranged so as to interact with the at least one planet wheel, which outer gear ring is connected to the static housing by a second splined connection.
