Location
Three multiple-disc clutches, the front, middle and rear multiple-disc clutches K1, K2 and K3, are located in the
planetary gear sets in the transmission housing.
Function 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 C1 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 (C2b) 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.
