ABSTRACT:
An actuating device for transferring a control force of an engaging/disengaging device to a double clutch for coupling a drive shaft to two transmission input shafts is described. The actuating device includes at least two first pistons corresponding to the first clutch, each having a first pressure surface, at least two second pistons corresponding to the second clutch, each having a second pressure surface. The first and second pistons are disposed parallel to an axis of the engaging disengaging device and within a graduated circle concentric to the axis. The actuating device also includes a plurality of elongatable piston guideways, each receiving one of the first and second pistons. The first pressure surfaces are couplable to each other and the second pressure surfaces couplable to each other.
