well friction point is just that... a point, where the clutch starts to slip. im looking for the name of a range (of which that point consists of one end of the range)
that said, i did not describe it accurately in the original post. 1. pedal fully pressed, clutch disengaged -> 2. pedal partly pressed, clutch still fully disengaged -> 3. friction point -> 3. clutch slipping (partially engaged) -> 4. clutch fully engaged, pedal fully depressed
if you are teaching someone to use the car, you have vocab u can use to describe points and ranges: disengaged, friction point (point), slipping (range), engaged (point)
the problem is that "disengaged" is usually thought of as a point (push the pedal all the way in) since the clutch itself is in a static state as opposed to the pedal which can be moving through a "disengagement range." i was just wondering if there was a term for that range on the clutch pedal though, since all the other terms really refer to the clutch itself and not the clutch pedal (i.e. the range between 1. and 3.)
so far we have:
clutch engagement length (clutch disengagement length?) - which sounds way too long
clutch play
clutch free play
clutch pedal play - i believe these three might be right from some limited googling
clutch take up length - possibly
clutch adjustment - sounds like something you do to set the range, not to describe it...
