The Ravigneaux gear set consists of the following components:
- Short planet gears (PL2k)
- Long planet gears (PL2l)
- Small internal-geared wheel (5)
- Dual planet carrier (6)
- Sun gear (7)
- Large internal-geared wheel (8)
The single front planetary gear system consists of the following components:
- Planet gears (PL9)
- Internal-geared wheel (12)
- Planet carrier (13)
- Sun gear (14)
The single rear planetary gear system consists of the following components:
- Planet gears (PL6)
- Internal-geared wheel (9)
- Planet carrier (10)
- Sun gear (11)
Power flow in 3rd gear, function
The following multi-disk brakes and multi-disk clutches are engaged:
- Multi-disk brake B2 (B2)
- Multi-disk clutch K1 (K1)
- Multi-disk clutch K3 (K3)
Ravigneaux gear set
Due to the engaged multi-disk clutch K1 (K1) the components of the Ravigneaux gear set are locked together and pass on the transmission input torque and transmission input speed unchanged to the internal-geared wheel (9).
Single rear planetary gear system
The internal-geared wheel (9) drives the planet gears (PL6) an. These roll over the stalled sun gear (11) and transmit the rotary motion to the planet carrier (10).
Single front planetary gear system
The internal-geared wheel (12) has a mechanical connection to the planet carrier (10) and rotates at the same speed.
The planet gears (PL9) roll on the stalled sun gear (14) and transfer the increased torque and reduced rotational speed as a result to the transmission output shaft via the planet carrier (13).
The transmission output shaft therefore rotates in the direction of rotation of the engine at reduced RPM relative to the transmission input shaft.
