GF27.10-P-3025SK Power flow in reverse gear, program selection "C", function
- Transmission 722.6








Principle of power flow in reverse gear:

Program selection "C"
Torque from the torque converter is increased via the drive shaft (1) and the center planetary gearset and rear planetary gearset and transferred with reversed direction of rotation to the output shaft (5). The following components are not engaged:
^ Front multi-disk brake (B1)
^ Rear multi-disk brake (B2)
^ Freewheel (F1)
^ Freewheel (F2)
^ Center multi-disk clutch (K2)

Rear planetary gearset
The engaged center multi-disk brake (B3) holds the planet carrier (B3) against the housing. The internal geared wheel (H4) turns at the input speed because of its mechanical connection with the locked planet carrier (V3). The planet gears (H2) turn between the ring gear (H4) and the sun gear (H1). The direction is reversed due to the securely held planet carrier (H3) so that the sun gear (H1) rotates in the opposite direction to the engine.

Center planetary gearset
The hollow gear (M4) is held securely in the housing by the center

Front planetary gearset
The planet carrier (V3) and sun gear (V1) are rigidly connected with each other via the engaged multi-disk clutch at the front (K1). The front planetary gearset is thus blocked and rotates due to the mechanical connection of the hollow gear (V4) and drive shaft (1) with input rpm as a closed unit. multi-disk brake (B3) via the mechanical connection to the planet carrier (H3). The sun gear (M1) turns backwards due to the engaged rear multi-disk clutch K3. The planet gears (M2) turn on the fixed ring gear (M4) and increase the torque from the sun gear (M1) to the planet carrier (M3). The output shaft (5) connected to the planet carrier (M3) turns at a reduced speed in the opposite direction to the running direction of the engine.
