Underdrive clutch applied

Low-reverse clutch applied

In first gear range, torque input is through the under-

drive clutch to the underdrive hub assembly. The
annulus gear. ‘The pinions are pinned to the rear ’
underdrive hub is splined to the rear sun gear. When
carrier and cause the rear carrier assembly to rotate
the underdrive clutch is applied, it rotates the under-
as they “walk around” the annulus gear. This pro-
drive hub and rear sun gear. The UR clutch is applied
vides the torque output for first gear. The other plane-

gear ratio is 2.84:1.

The rear sun gear drives the rear planetary pinion
gears. The rear planetary pinion gears are forced
Second Gear
Underdrive clutch applied
(turns rear sun)
2-4 clutch applied

id
Second gear is achieved by having both planetary
rear pinions rotate the rear annulus/front carrier as-
gear sets contribute to torque multiplication. As in
sembly. The pinions of the front carrier will “walk
first gear, torque input is through the underdrive
around” the stationary front sun gear. This transmits
clutch to the rear sun gear. The 2-4 clutch is applied
torque to the front annulus/rear carrier assembly
to hold the front sun gear stationary. The rotating
which provides output torque and a gear ratio of
rear sun gear turns the rear planetary pinions. The
1.57:1.
