The invention relates to a clutch actuator (100) for transmitting a disengaging force FA to a disengaging device (22) of a clutch (101), comprising an actuating element (13, 14, 24) to which the disengaging force FA can be applied and comprising a piston rod (15, 25) for transmitting the disengaging force FA from the actuating element (13, 14, 24) to the disengaging device (22). The piston rod (15, 25) is mounted against a connection region (14, 24) of the actuating element (13, 14, 24) such that the piston rod (15, 25) can be moved towards the connection region (14, 24) by the clutch reaction force FK of the clutch (101), and the positioning of the connection region (14, 24) and the piston rod (15, 25) relative to each other as a result of said movement can be fixed by applying the disengaging force FA to the actuating element (13, 14, 24). The actuating element (13, 14, 24) is designed to at least partly deflect the disengaging force FA so as to produce a normal force FN and/or a radial force FR which acts between the connection region (14, 24) and the piston rod (15, 25), and the normal force FN and/or the radial force FR fixes the position of the connection region (14, 24) and the piston rod (15, 25) relative to each other. |
