Automatic Transmission - Honda NHSO aeroBO 1983 Shop Manual

AUTOMATIC TRANSMISSION

The automatic transmission provides various drive ratios between the engine and rear wheel according to the engine speed and
load. It accomplishes this by two sets of pulleys; drive and driven, and by the use of a drive belt between the pulleys. The drive
pulley is attached to the engine crankshaft. The driven pulley is attached to a shaft and also incorporates a centrifugal clutch.
There is a final gear reduction between the driven pulley and rear wheel, providing an additional increase in torque.
MOVABLE DRIVE FACE
DRIVEN PULLEY
When the engine is running at lovy speed, the unit
can increase or multiply torque so that more torque
is delivered than at high engine speed through a
greater drive ratio.
REDUCTION RATIO:

DRIVE PULLEY
As the speed of the engine increases, or load on the
rear wheel decreases, centrifugal force on the weight
rollers throws the rollers radially outward. When the
rollers are forced outward, they press·in the mov­
able face of the drive pulley closer to the drive face
which will result in a reduced drive ratio between
the driven and drive pulleys.
