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

GF27.10-P-3013SXA Power flow in 3rd gear, function
- Transmission 722.6









Principle of power transmission in 3rd gear:
Via the drive shaft (1) and involving the center planetary gear set the torque coming from the torque converter is increased and transmitted to the output shaft (5).

The following are not engaged:
^ Multi-disk brake B1 (21)
^ Multi-disk brake B3 (23)
^ Freewheel F1 (27)
^ Freewheel F2 (28)
^ Multi-disk clutch K3 (26)

Front planetary gear set
The planet carrier (29/3) and sun gear (29/1) are permanently connected to each other via the engaged multi-disk clutch K1 (24). The planetary gear set is thus blocked and due to the mechanical connection between the ring gear (29/4) and drive shaft (1) rotates with input speed as a closed assembly.

Rear planetary gear set
The multi-disk clutch K2 (25) is engaged and transmits the input speed of the drive shaft (1) via the ring gear (31/4) to the planet carrier (31/3). Via the mechanical connection to the locked front planetary gear set the ring gear (31/4) rotates at the same speed as the planet carrier (31/3). The planetary gear set is therefore locked and turns as a closed assembly.

Center planetary gear set
Due to the engaged multi-disk clutch K2 (25) the ring gear rotates at input speed. The sun gear is supported at the housing via the multi-disk brake B2 (22) (30/1). The planetary gears (30/2) revolve around the stationary sun gear (30/1) and ensure that torque is increased when power is transmitted from the ring gear (30/4) to the planet carrier (30/3). The output shaft (5) connected to the planet carrier (30/3) turns at a reduced speed in the direction of rotation of the engine.
