Patent ID: 8191695

Claim:
An actuating mechanism for engaging and disengaging a separating clutch of a single-clutch or multiple-clutch transmission, which has a housing, for a motor vehicle, comprising: an actuating drive; a cam segment having a curved slot with a radially inward facing contact flank and being rotatable about a first bearing, said first bearing being fixed with respect to the housing, and being rotatable by the actuating drive in an engagement rotational direction or a disengagement rotational direction; an engagement fork which is rotatable about a second bearing, said second bearing being fixed with respect to the housing, and which is coupled at one side of the fork to the cam segment by means of a cam follower and which can be coupled on an opposite side of the fork to the separating clutch in such a way that the separating clutch is closed in the event of a rotation of the cam segment in the engagement rotational direction and the separating clutch is opened in the event of a rotation of the cam segment in the disengagement rotational direction; with the cam follower engaging into the curved slot and being guided by a contour of the contact flank in the event of a rotation of the cam segment; and with the contour being shaped such that the cam follower is offset in a radial direction of the cam segment in the event of an actuation of the actuating drive.
