Clutch device

A clutch device comprising:

• at least one counter-pressure plate;
• a contact plate movable relative to the counter-pressure plate to a limited extent in an axial direction of the clutch device to frictionally clamp a clutch plate between the counter-pressure plate and the contact plate;
• and
• a wear adjuster to compensate for wearing of the clutch plate, where the wear adjuster has at least one drive ring rotatable and clampable in the axial direction and at least one ramp ring rotatable and clampable in the axial direction, the ramp ring connected to the drive ring via a plurality of circumferentially spaced torque-transferring links permitting limited relative travel in two circumferential directions of the clutch device, where a rigidity of each of the links is different when moved in a first of the two circumferential directions than when moved in a second of the two circumferential directions, wherein each link has a buckling spring extending in the circumferential directions from the ramp the drive ring.

• wherein the link has a buckling spring extending in the circumferential directions,
• wherein the buckling spring is attached at one end to one of the drive ring and the ramp ring,
• wherein the buckling spring is attached at an other end to a pushing element attached to the other of the drive ring and the ramp ring,
• wherein the pushing element is slidable in the circumferential directions and is supported tiltably in both the axial direction and a radial direction of the clutch device on one of the drive and ramp rings.
