Function of Power Flow In Reverse Gear Program Selection "W"

PRINCIPLE OF POWER TRANSMISSION IN REVERSE GEAR, PROGRAM SELECTOR SWITCH POSITION "W"
- Via the input shaft (1) and using the center and rear planetary gear set, the torque from the torque converter is increased and transmitted in the opposite direction of rotation 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 (Y4) and the input shaft (l).

REAR PLANETARY GEAR SET
- The planet carrier (H3) is fixed to the housing due to the engaged multiple-disc brake 83. The internally-geared wheel (H4) rotates at input speed due to the mechanical connection to the locked front planet carrier (V3). The planet gears (H2) roll between the internally-geared wheel (H4) and sun gear (H1). The direction reverses due to the fixed planet carrier (I) so that the sun gear (H1) rotates in the opposite direction to the engine.

CENTER PLANETARY GEAR SET
- The internally-geared wheel (M4) is fixed to the housing by multiple-disc brake B3 via the mechanical connection to the planet carrier (H3). The sun gear (M1) rotates backwards due to the engaged multiple-disc clutch K3. The planet gears (M2) roll on the fixed internally-geared wheel (M4) and make for an increase in torque from the sun gear (M1) to the planet carrier (M3). The output shaft (5) connected to the planet carrier (M3) rotates at reduced speed in the opposite direction so she engine
