CONTINUOUSLY VARIABLE TRANSMISSION (CVT)
Repair and Service Manual
Read all of Section B and this section before attempting any procedure. Pay particular attention to all Notes, Cautions and Warnings.
B
conditions, the drive belt friction is overcome by the
additional 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.
