GF27.10-P-3013GZ Power flow in 3rd gear, function
- Transmission 722.9






The Ravigneaux gear set consists of the following components:
^ Short planet gears
^ Long planet gears
^ Small internal-geared wheel
^ Dual planet carrier
^ Sun gear (7)
^ Large internal-geared wheel

The front single planetary gear set consists of the following components:
^ Planetary gears (52)
^ Internal-geared wheel (12)
^ Planet carrier (13)
^ Sun gear (14)

The rear single planetary gear set consists of the following components:
^ Planetary gears (51)
^ 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:
^ Multidisk brake B2
^ Multidisk clutch K1
^ Multidisk clutch K3

Ravigneaux gear set
Due to the engaged multidisk clutch 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 ring gear (9).

Single rear planetary gear system
The ring gear (9) drives the planetary gears (51). 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 planetary gears (52) roll on the stalled sun gear (14) and transfer the increased torque and reduced rotational speed to the transmission output shaft via the planet carrier (13). The transmission output shaft thus rotates with reduced transmission input speed in the direction of rotation of the engine.
