Function of Power Flow In 3RD Gear

PRINCIPLE OF POWER TRANSMISSION IN 3RD. GEAR
- Via the input shaft (1) and using the center planetary gear set the torque from the torque converter is increased and transmitted to the output shaft (5).

FRONT PLANETARY GEAR SET
- The planet carrier (V3) and sun gear (V1) are rigidly connected to each other via the engaged multiple-disc clutch K1. The planetary gear set is therefore locked and rotates as a closed unit at the input speed due to the mechanical connection between the internally-geared wheel (V4) and the input shaft (1).

REAR PLANETARY GEAR SET
- The multiple-disc clutch K2 is engaged and transmits the input speed of input shaft (1) to the planetary carrier IH3) via the internally geared wheel (M4). The internally-geared wheel (H4) rotates in the same way as the planet carrier (H3) via the mechanical connection to the locked front planetary gear set. The planetary gear set is therefore locked and rotates as a closed unit.

CENTER PLANETARY GEAR SET
- The internally-geared wheel (M4) rotates at the input speed due to the engaged multiple-disc clutch K2. The sun gear (M1) is supported on the housing via the multiple-disc brake B2. The planet gears (M2) roll on the fixed sun gear (M1) and make for an increase in torque from the internally-geared wheel (M4) to the planet carrier (M3). The output shaft (5) connected to the planet carrier (M3) rotates at reduced speed in the direction of rotation of the engine.
