Clutch is stated after pressure is reduced, actual speed is poor between master and slave moving plate, the output to the clutch
Moment of torsion is controlled, until the speed discrepancy between the clutch driving disk and driven disc is equal to rotating speed of target
Difference.
As seen from Figure 2, using the control method of clutch described in the embodiment of the present invention, to described
After the torque value of clutch output is controlled, the increasing degree of the master and slave moving plate rotating speed of the clutch by
Gradually close (referring to change procedure of the curve 3 and 4 within the t4 time periods), corresponding actual speed difference also by
Gradually close rotating speed of target poor (referring to change procedure of the curve 6 within the t4 time periods), the moment of torsion of output with send out
Difference between the moment of torsion of motivation output is also gradually stable (referring to change of the curve 1 and 2 within the t4 time periods
Change process).At the end of the t4 times, the clutch rubs state into stable micro- cunning.
