Abstract

A shiftable planetary transmission (1) includes a planet carrier (2), a plurality of planet gears (3) rotatably arranged at the planet carrier (2), a sun gear (4), and a ring gear (5). The sun gear (4) and the ring gear (5) mesh with the planet gears (3). The planet carrier (2) includes at least one connecting element (6), which is axially displaceable therein. The at least one connecting element (6), on a first side of the planet carrier (2), is at least indirectly connected to an actuator (7) and, on a second side of the planet carrier (2), is at least indirectly connected to a first dog element (8). The first dog element (8) is displaceable, by an actuator actuation, between a first shift position and at least a second shift position due to an axial displacement of the at least one connecting element (6) in the planet carrier (2).
