Operation
If the piston (B1a) on multiple-disc brake B1 is subjected to oil pressure, it presses the internal and external discs of the disc set together. The front sun gear (V1) on the housing is locked via the internal multiple-disc carrier (B1c). The front planetary gears (V2) roll on the front sun gear (V1).

If the rear multiple-disc brake (B2) is engaged via the piston (B2a), then this presses the disc set together. The center sun gear (M1) is locked against the housing via the internal multiple-disc carrier (B2c). The center planetary gears (M2) roll on the center sun gear (M1).

If the center multiple disc brake (B3) is engaged via the piston (B3a), then the rear planetary gear carrier (H3) and the center hollow gear (M4) are locked. When the center multiple-disc brake (B3) is engaged the direction of rotation reverses.
