Transmission, in particular an automated power-branched multi-speed gearing

An automated power-split multi-speed transmission (1), comprising at least a first, a second and a third power branch (P1, P2, P3), the first power branch (P1) is connected to a first shaft (2), the second power branch (P2) is connected to a second shaft (3) and the third power branch (P3) is connected to a third shaft (4), the first, the second and the third shafts (2, 3, 4) communicate with a downstream planetary gearset (5), the first shaft (2) is configured with at least a first partial transmission ratio (i1), the second shaft (3) is configured with at least a second partial transmission ratio (i2) and the third shaft (4) is configured with at least a third partial transmission ratio (i3), the first power branch (P1) has a first control element (S6) for connecting the first power branch (P1) to a power flow at the first partial transmission ratio (i1), the second power branch (P2) has a second control element (S5) for connecting the second power branch (P2) to a power flow at the second partial transmission ratio (i2), and the third power branch (P3) has a third control element (S1) for connecting the third power branch (P1) to a power flow at the first partial transmission ratio (i3), and at least one of the second and third shafts (3, 4) of the planetary gearset (5) interacting with an additional control element (S2, S4), via which the at least one of the second and third shafts (3, 4) can be supported in relation to a housing (6) and a third additional control element (S3), the third additional control element (S3), in a closed state, blocks the planetary gearset (5), being arranged between the second and third shafts (3, 4) of the planetary gearset (5), the transmission (1) having eight forward gears.
