Abstract

The invention relates to a power-shift multi-speed transmission (10) provided in the power train of a vehicle, comprising at least one sun gear (14, 80), at least one stepped planetary gear (16, 22), at least one ring gear (34, 36), and an input shaft (12) and an output shaft (40). The power-shift multi-speed transmission (10) can be shifted into a shift mode of a first speed or into a shift mode of a second speed and vice versa by means of the at least one stepped planetary gear (16, 22). A first brake (30) is associated with a first ring gear (34) and a second brake (32) is associated with a second ring gear (36). Depending on the actuation of these brakes, in the shift modes there is at least one torque flow under acceleration, or at least one torque flow on overrun, through the power-shift multi-speed transmission (10).
