Automatic Continuous Variable Transmission; Continuous Variable Transmission; Shift Motor; Drive Pulley - Eton ATV RXL 50 Service Manual

Shift Motor

Check shift motor whether it's action is normal as follow
data:
Brush
Disassembly mission side cover, parts of shift mechanism
and mission cover.
Get seal and bearing after disassembly shift motor of
mission cover.
Seal Bearing
Check seal and for wear or fatigue.
Replace it if necessary.

7.4 AUTOMATIC CONTINUOUS VARIABLE TRANSMISSION

This transmission is the combination of automatic
centrifugal clutch and V-belt continuous variable
transmission, which can change the transmission
ratio automatically.
When engine speed increase, the drive pulley will
be push to belt by the centrifugal force from six rollers.
Then the pitch circle of belt in drive pulley will
be larger.
The belt at driven pulley is forced to move to
the center of shaft, then the radius of pitch circle
is decreased.
The transmission ratio is therefore altered by the
alteration of pitch circle's radius.
(In the drawing, "H" means high speed, "L" means low speed)

7.5 CONTINUOUS VARIABLE TRANSMISSION

V-Belt
Made of rubber fiber, resistant to head, pressure and
abrasion. The inner side of the Belt is toothed.

Drive Pulley

Due to the increasing engine speed, the rollers push
the movable drive face by centrifugal force. Then the
belt is pressed and enlarges its turning radius.
The aluminum fan is installed on the exterior of fixed
drive face. It can reduce the belt temperature.
