CONTINUOUSLY VARIABLE TRANSMISSION (CVT)
Read all of Section B and this section before attempting any procedure. Pay particular attention to all Notes, Cautions and Warnings
As the driven clutch slows, the belt rides lower in the
drive clutch sheaves. The driven clutch compensates by
closing in response to the torsion spring and cam.
Increased Load
When the vehicle is at governed speed and starts to
climb a grade or is subjected to other increased load con
ditions, the drive belt friction is overcome by the addi
tional load and the belt seeks a point where it can
achieve adequate friction to overcome its slippage. The
belt moves outwards on the driven clutch which closes
due to the torsion spring moving the moveable sheave
against the torque ramps. The movement of the drive belt
overcomes some of the centrifugal force exerted by the
cams in the drive clutch. This forces the belt lower into
the drive clutch which increases the drive ratio. This
'downshifting' applies more torque to the rear axle with
out an appreciable change to the engine speed since the
governor opens the carburetor in direct response to the
reduction in ground speed.
Equilibrium
The CVT functions because the drive and driven clutches
maintain equilibrium. Clutch sets are tuned to the vehicle
that they are designed to operate. Changes in vehicle
weight or desired performance characteristics require
that both clutches be tuned to the needs of the vehicle
and remain compatible with each other.
