Self-adjusting clutch actuator

A self-adjusting clutch actuator, comprising:

• a transmission element configured for displacement in a displacement direction;
• a compensation mechanism having a piston configured for displacement in the displacement direction, the compensation mechanism being configured to enable a first relative displacement of the transmission element in the displacement direction relative to the piston if no actuating force is introduced into the clutch actuator, and to block the first relative displacement in the displacement direction if an actuating force is introduced into the clutch actuator by a first friction element brought into contact in a frictionally locking manner with a mating element, the first friction element being configured to carry out a second relative movement with respect to the mating element if the first relative displacement is not blocked by the compensation mechanism;
• and
• a transmission mechanism arranged between the transmission element and the piston, the transmission mechanism being configured to cause the second relative movement by way of the first relative displacement in the displacement direction of the transmission element relative to the mating element,
• wherein
• the first friction element has a fixed connection to the transmission element in the direction of the second relative movement, and
• the compensation mechanism is configured to bring at least two faces of the first friction element into contact with the mating element directly, via at least one intermediate element, or both directly and via the at least one intermediate element.
