Clutch control apparatus

摘要

A clutch control apparatus includes a clutch disk (23), which is engaged with a flywheel (21), by means of a diaphragm spring (25); a release mechanism (including a rod and an electric motor (32)) for pressing a central portion of the diaphragm spring; and a clutch control circuit (40). The flywheel (21) and an outer circumferential portion of the diaphragm spring (25) abut each other via taper portions of a pressure plate (24) and an adjust wedge member (29). The clutch control circuit calculates an ideal clutch load and an output torque of the electric motor for a detected stroke of the rod. On the basis of these values, the clutch control circuit obtains the acceleration of the rod. The clutch control circuit (40) estimates a stroke of the rod from the obtained acceleration and causes the adjust wedge member (29) to rotate such that a detected actual stroke and the estimated stroke become equal, thereby modifying the attitude of the diaphragm spring accordingly.
