Function of Power Flow In 1ST Gear

PRINCIPLE OF POWER TRANSMISSION IN 1ST GEAR
- Via the input shaft (1) and using all three planetary gear sets, the torque from the torque converter is increased and transmitted to the output shaft (5).

FRONT PLANETARY GEAR SET
- The internally-geared wheel (V4) Is driven via the input shaft (1). in drive mode the sun gear (V1) is supported via the locked freewheel F1 and in overrun mode on the housing via the engaged multiple-disc brake B1. The planet gears (V2) roll on the fixed sun gear tV1) and make for an increase in torque from the internally-geared wheel (V4) to the planet carrier (V3). The planet carrier (V3) moves at a reduced speed in the direction of rotation of the engine.

REAR PLANETARY GEAR SET
- The internally-geared wheel (H4) rotates at reduced speed due to the mechanical connection to the front planet carrier (H3). The sun gear (H1) is supported via the engaged multiple-disc brake B2 and in drive mode via the locked freewheel F2, in overrun mode it is supported on the housing via the engaged multiple-disc clutch K3. The planet gears tH2) roll on the fixed sun gear (H1) and make for an increase in torque from the internally-geared wheel (H4) to the planet carrier (H3). The planet carrier (V3) moves at a reduced speed in the direction of rotation of the engine

CENTER PLANETARY GEAR SET
- The internally-geared wheel (M4) is driven at the same speed as the rear planet carrier (H31 due to a mechanical connection. The sun gear (M1) is supported the housing via the multiple-disc brake B2. The planet gears (M2) roll on the fixed sun gear (M 1) and make for an increase in torque from the internally-geared wheel (M4) to the planet carrier (M3). The output shaft connected to planet carrier (M3) rotates at a reduced speed in the direction of rotation of the engine
