Power Flow In 3RD Gear

Component Illustration:

Principle Of Power Flow 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).

Front Planetary Gearset:
The planet carrier (V3) and sun gear (V1) are connected via the engaged multiple-disc clutch K1. The planetary gearset is therefore locked and turns as a closed unit at the input speed due to the mechanical connection of the ring gear (V4) and propeller shaft (1).

Rear Planetary Gearset:
The multiple-disc dutch K2 Is engaged and transfers the input speed of the propeller shaft (1) to the planet carrier (H3) via the ring 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 Gearset:
The ring gear (M4) turns at the input speed as a result of the engaged multiple-disc dutch K2. The sun gear (M1) is held against the housing by the multiple-disc brake B2. The planet gears (M2) turn on the fixed sun gear (M1) and increase the torque from the ring gear (M4) to 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.
