Function of Power Flow In 5TH Gear

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

FRONT PLANETARY GEAR SET
- The internally-geared wheel (V1) 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 is supported on the housing via the engaged multiple-disc brake B1. The planet gears (V2) roll on the fixed sun gear (V1) 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 multiple-disc clutch K2 is engaged and transmits the input speed of the input shaft (1) to the planet carrier (H3) via the internally-geared wheel (M4). The internally-geared wheel (H4) rotates at reduced speed due to the mechanical connection to the front planet carrier (V3). The planet gears (H2) roll between the internally-geared wheel (H4) and sun gear tH1). The sun gear (H1) moves at an increased speed in the direction of rotation of the engine.

CENTER PLANETARY GEAR SET
- The internally-geared wheel (M4) rotates at the input speed due to the engaged multiple-disc clutch K2. the multiple-disc clutch K3 transmits an increased speed to the sun gear (M1) due to the connection to the sun gear (H1). The planet gears (M2) roll between the internally-geared wheel (M4) and sun gear (M1). The speed of the planet carrier (M3) and the output shaft (5) connected to it is between the speed of the internally-geared wheel (M4) and sun gear (M1). This produces a high-speed ratio
