Operation
Front multiple-disc clutch (K1)
If the piston (K1a) on the front multiple-disc clutch (k1) is subjected to oil pressure, it presses the internal and external discs of the disc set together.
The front sun gear (V1) is connected to the front planetary gear carrier (V3) via the external multiple-disc carrier (K1b) and the internal multiple-disc carrier (K1c). The front planetary gear set is thus locked and turns as a closed unit.
Center multiple-disc clutch (K2)
If the center multiple-disc clutch (K2) is engaged via the piston (K2a), the piston compresses the disc set Via the internal multiple-disc carrier (K2b) and the center planetary gear carrier (M3) on which the internal discs are seated, the front hollow gear (V4) of the front planetary gear set is connected to the center hollow gear (M4) of the center planetary gear set. The front hollow gear (V4) and the center hollow gear (M4) move at the same speed as the drive shaft (1).
Rear multiple-disc clutch (K3)
If the rear multiple-disc clutch (K3) is engaged via the piston (K3a), then this compresses the disc set. The center sun gear (M1) of the center planetary gear set is connected to the rear sun gear (H1) of the rear planetary gear carrier via the external multiple-disc carrier (K3b) and internal multiple-disc carrier (K3c). The center sun gear (M1) and the rear sun gear (H1) move at the same speed.
