Front Planetary Gear Set
The planetary carrier (13) and sun gear (21) are connected via the engaged driving clutch K1 (7). The planetary
gearset is therefore locked and turns as a closed unit at the input speed due to the mechanical connection of the
annulus gear (8) and driveshaft (25).
Center Planetary Gear Set
The annulus gear (10) turns at the input speed as a result of the engaged driving clutch K2 (9). The sun gear (22)
is held against the housing by the multi-disc holding clutch B2 (6). The planetary pinion gears (18) turn on the fixed
sun gear (22) and increase the torque from the annulus gear (10) to the planetary carrier (14). The output shaft (26)
connected to the planetary carrier (14) turns at a reduced speed in the running direction of the engine.
