Location

Three multiple-disc clutches, the front, middle and rear multiple-disc clutches K1, K2 and K3, are located in the plan-
etary gear sets in the transmission housing.

Funtion and description

A multiple-disc clutch consists of a number of internally toothed discs (10) on an internally toothed disc carrier and
externally toothed discs (9) on an externally toothed disc carrier.
If the piston (C1a) on multiple-disc clutch K1 is subjected to oil pressure, it presses the internal and external discs of the
disc set together. The sun gear (V1) is locked with the planet carrier (V3) via the externally toothed disc carrier (C1b) and
the internally toothed disc carrier (C1c). The front planetary gear set is thus locked and turns as a closed unit. If the
multiple-disc clutch C2 is actuated via the piston (C2a), the piston compresses the disc set. The ring gear (V4) of the
front planetary gear set is locked with the ring gear (M4) of the middle planetary gear set via the externally toothed disc
carrier (K2b) and the middle planet carrier (M3) on which the internally toothed discs are seated. Ring gear (V4) and ring
gear (M4) turn at the same speed as the input shaft (1). If the multiple-disc clutch C3 is actuated via the piston (C3a), the
piston compresses the disc set. The sun gear (M1) of the middle planetary gear set is locked with the sun gear (H1) of
the rear planetary gear set via the externally toothed disc carrier (C3b) and the internally toothed disc carrier (C3c). Sun
gear (M1) and sun gear (H1) turn at the same speed.
