Abstract
A shiftable planetary transmission having a housing, a non-rotatable or rotatable transmission component, a sun gear, a carrier and at least one planet gear mounted on the carrier. A rotatable ring gear is connected to the non-rotatable or rotatable transmission component. The ring gear has an annular surface facing the interior surface of the transmission component and a coupling arrangement is non-rotatably connected to the ring gear and a spring-loaded hydraulic activation mechanism is located within the ring gear to axially move the coupling arrangement.
