2.3 PRINCIPLE OF COOLING SYSTEM FOR CVT

Air fl ow
The drive pulley is equipped with the cooling fan which
rotates in the CVT case to draw ambient air in with the
same principle of the centrifugal pump in order to dis-
charge heat generated by friction between the belt and
pulley.
As the centrifugal fan rotates and draws air, this air
moves toward the end of the fan blades, i.e. toward the
circumference of the fan.

Then, the negative pressure is generated on the center
of the fan. As the air suction hose of the CVT case is
located near the center of the fan as shown in the fi g-
ure, this negative pressure makes the hose draw am-
bient air easier. This air cools the CVT pulley and belt
and moves toward the driven pulley and outlet hole to
be discharged.
