CLUTCH PEDAL
l An assistireturn spring is used on BP DO-K Turbo engine-equipped models to reduce the required pedal
effort.
l The assist/return spring is mounted vertical to the pedal for a compact arrangement.
wiNGi B G”3 * RANGE A
RANGE B + + RANGE A
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.
