Operation
With the clutch pedal fully
released, the
assist/return spring is compressed, causing force
F to
act upon ful-
crum 0,
As a result, force Fy is created, and acts upon fulcrum @ to hold the pedal outward.
1 1 When clutch pedal depressed.
(1) Fukrum @ within range A
When the pedal is depressed, it moves inward, centered upon fulcrum @.
Fy, which is the force opposing pedal movement, acts upon futcrum @ until fulcrum @ crosses the
imaginary line connecting fulcrums @ and @
As a
result,
there
is a slight feeling of resistance when the clutch pedal is first depressed.
(2) With fulcrum @ within range 8
When fulcrum @ crosses the imaginary line between fulcrums @ and @, Fy now acts in the same
direction as pedal
movement, thus
reducing the force required to depress the pedat.
