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.
Claims14
A shiftable planetary transmission having a housing, a non-rotatable transmission component and a rotatable transmission component, a sun gear, a carrier, at least one planet gear mounted on said carrier, and a rotatable ring gear for connection to said non-rotatable transmission component and to said rotatable transmission component, said ring gear having a surface facing each of said transmission components, a first coupling means non-rotatably connected to said ring gear, and activation means located within said ring gear for moving said first coupling means axially relative to said ring gear into contact with a transmission component.
