Abstract
An actuating device for exerting a force that causes two components arranged to be rotatable relative to each other about an axis of rotation to be urged axially away from each other comprising a radial support element forming a first hydraulic pressure chamber and a second hydraulic pressure chamber, each of the pressure chambers surrounding the axis of rotation and the first pressure chamber being in fluid connection with the second pressure chamber. The actuating device further comprises a first piston axially supported on the first component for sealing the first pressure chamber in an axially displaceable way and a second piston axially supported on the second component for sealing the second pressure chamber in an axially displaceable way.
