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 4th 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 K2 (K2)
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 RPM of the ring gear (9) and ring gear (12) is the same due to the engaged multi-disk clutch K2 (K2). As a result the single rear planetary gear system is locked and not actively involved in the gear ratio.
Single front planetary gear system
Due to the engaged multi-disk clutch K2 (K2) the internal-geared wheel (12) is driven at transmission input 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.
