When holding the effect departed from diaphragm spring off axis, platen presses to clutch drived disk assy under the effect of diaphragm spring, it is achieved clutch
" joint action "；When release bearing advances to clutch drived disk assy side, compress the center-side of diaphragm spring, then diaphragm bullet
Spring drives platen to separate with clutch drived disk assy, it is achieved " separating action " of clutch.During This move, if release bearing
Promote the distance that moves of the diaphragm spring release travel less than clutch, then occur platen and clutch drived disk assy and flywheel with
Separate between clutch drived disk assy not thoroughly, there are relative sliding wear, be the quasi integration state of clutch.
When the separation of clutch or when combining slow movement, extend the clutch working time under quasi integration state,
Make between clutch driven plate and platen, between clutch driven plate and flywheel, produce sliding wear.The frictional heat that sliding wear causes is short
Sharply increase in time, cause clutch driven plate, platen and flywheel temperature to rise rapidly, clutch time serious, can be made to burn.
After clutch is completely combined, sliding wear disappears, and clutch quickly cools down.Substantial amounts of heat exchange this within a short period of time, cause from
Clutch produces impact thermal stress.When stress exceedes the strength of materials, produce heat fatigue cracking and then cause the damage of clutch component
Bad.
Up to now, the testing machine of the thermal-shock resistance for studying clutch and engine flywheel there is not yet open report
Lead.
