General power flow in 6th gear
The following multidisk brakes and multidisk clutches are engaged:
- Multidisk brake B1 (42)
- Multidisk clutch K2 (47)
- Multidisk clutch K3 (48)
The power flow in 6th gear takes place via the following gear sets:
- Ravigneaux gear set
- Rear single planetary gear set
- Front single planetary gear set
Ravigneaux gear set
The small ring gear (5) is driven via the transmission input shaft. The long planetary gears (50) roll over the stalled sun gear (7) and transmit the increased torque and reduced rotational speed as a result to the dual planet carrier (6).
Rear single planetary gear set
The ring gear (9) rotates at the same speed due to the mechanical connection to the dual planet carrier (6). The planetary gears (51) transmit the rotary motion to the sun gear (11). Sun gear (11) passes on the rotational speed to sun gear (14) via the closed multidisk clutch K3 (48).
Front single planetary gear set
The transmission input torque and input speed are transmitted to the ring gear (12) by the closed multidisk clutch K2 (47). The speed difference between the sun gear (14) and ring gear (12) results in a speed increase and torque reduction. These are passed on via the planet carrier (13) to the main shaft. The main shaft therefore rotates with an increased input speed in the direction of engine rotation.
