OPERATION
The multi-disc holding clutches (1, 4 and 5) connect the annulus gear, sun gear, or planetary carrier of a planetary
gear set against the transmission housing in order to transmit the drive torque.
If the piston (16) on multi-disc holding clutch B1 (1) is subjected to oil pressure, it presses the internal (3) and
external discs (2) of the disc set together. The internally toothed disc carrier (15) locks the sun gear (14) against the
housing. The planetary pinion gears (13) turn on the sun gear (14).
If the multi-disc holding clutch B2 (5) is actuated via the piston (7), the piston compresses the disc set. The inter-
nally toothed disc carrier (8) locks the sun gear (12) against the housing. The planetary pinion gears (11) turn on the
sun gear (12).
If the multi-disc holding clutch B3 (4) is actuated via the piston (6), the planetary carrier (9) and the annulus gear
(10) are locked. When the multi-disc clutch B3 (4) is actuated, the direction of rotation is reversed.
