GF27.10-P-3013G Power Flow In 3rd Gear, Function

GF27.10-P-3013G Power flow in 3rd gear, function
- TRANSMISSION 722.6








Principle of power transmission in 3rd gear:
Torque from the torque converter is increased via the propeller shaft (1) and the center planetary gearset and transferred to the output shaft (5)."

The following are not engaged:
Front multi-disk brake (B1)
Center multi-disk brake (B3)
Freewheel F1
Freewheel F2
Rear multi-disk clutch (K3)

Front planetary gear set
The planet carrier (V3) and sun gear (V1) are rigidly connected to each other via the engaged front multi-disk clutch (K1). The planetary gearset is therefore blocked and turns as a closed unit at the input speed due to the mechanical connection of the ring gear (V4) and propeller shaft.

Rear planetary gear set
The center multi-disk clutch (K2) is engaged and transmits the input speed of the input shaft (1) to the planet carrier (H3) via the hollow gear (M4). The ring gear (H4) turns in the same way as the planet carrier (H3) due to the mechanical connection with the locked front planetary gearset. This planetary gearset is therefore locked and turns as a closed unit.

Center planetary gear set
The hollow gear (M4) rotates at input speed due to the engaged center multi-disk clutch (K2). The sun gear (M1) is supported in the housing via the multi-disk brake (B2). The planet gears (M2) roll over the fixed sun gear (M1) and provide an increase in torque between the internal gear (M4) and the planet carrier (M3). The output shaft (5) connected to the planet carrier (M3) turns at a reduced speed in the running direction of the engine.
