MERCEDES-BENZ SPRINTER 2006 Service Manual Speed and torque are not converted by the direct

Speed and torque are not converted by the direct
gear ratio of the 4th gear. Power is transferred from
the input shaft (25) to the output shaft (26) via three
locked planetary gearsets. (Fig. 8) (Fig. 9)
Front Planetary Gear Set
The planetary carrier (13) and sun gear (21) are
connected via the engaged multiple-disc clutch K1
(7). The planetary gearset is therefore locked and
turns as a closed unit at the input speed due to the
mechanical connection of the annulus gear (8) and
the input shaft (25).
Rear Planetary Gear Set
The multiple-disc clutch K2 (9) is engaged and
transfers the input speed of the input shaft (25) to
the planetary carrier (15) via the annulus gear (10).
The annulus gear (11) turns in the same way as theplanetary carrier (15) due to the mechanical connec-
tion with the locked front planetary gearset. The
planetary gearset is therefore locked and turns as a
closed unit.
Center Planetary Gear Set
The annulus gear (10) turns at the input speed as
a result of the engaged multiple-disc clutch K2 (9).
The multiple-disc clutch K3 (12) connects the sun
gears (22) and (23) of the rear and center planetary
gearset. The planetary gearset is locked by the same
speeds of the annulus gear (10) and the sun gear (22)
and it turns as a closed unit.

Front Planetary Gear Set
The annulus gear (8) is driven by the input shaft
(25). The sun gear (21) is held against the housing by
the locked freewheel F1 (20) during acceleration and
via the engaged multiple-disc holding clutch B1 (4)
during deceleration. The planetary pinion gears (17)
turn on the fixed sun gear (21) and increase the
torque from the annulus gear (8) to the planetary
carrier (13). The planetary carrier (13) moves at a
reduced speed in the running direction of the engine.Rear Planetary Gear Set
The multiple-disc clutch K2 (9) is engaged and
transfers the input speed of the input shaft (25) to
the planetary carrier (15) via the annulus gear (10).
The annulus gear (11) turns at a reduced speed due
to the mechanical connection with the front plane-
tary carrier (13). The planetary pinion gears (19)
turn between the annulus gear (11) and the sun gear
(23). The sun gear (23) moves at an increased speed
in the running direction of the engine.

The planetary carrier (15) is held against the hous-
ing by the engaged multiple-disc holding clutch B3
(5). The annulus gear (11) turns at a reduced speed
due to the mechanical connection to the front plane-
tary carrier (13). The planetary gears (19) turn
between the annulus gear (11) and the sun gear (23).
The direction is reversed by the held planetary car-
rier (15) so that the sun gear (23) turns in the oppo-
site direction to the running direction of the engine.
