Clutch actuation mechanism

A clutch actuation mechanism for actuating a clutch operator of a spring loaded friction clutch, the clutch actuation mechanism comprising:

• at least one rotary disc connectable to the clutch operator, the at least one rotary disc being supported by a radial bearing defining a disc rotary axis of the at least one rotary disc and being coupled to a motor to provide a first torque to the at least one rotary disc;
• a pin attached to the at least one rotary disc with an offset from the disc rotary axis;
• a lever having a contacting surface and being pivotally supported to pivot around a lever pivot axis, wherein the lever pivot axis and the disc rotary axis are substantially parallel;
• and
• a spring that forces the contacting surface of the lever against the pin to thereby provide an additional torque to the at least one rotary disc,
• wherein the pin travels over the contacting surface when the at least one rotary disc rotates to open or close the spring loaded friction clutch via the clutch operator, and
• wherein the contacting surface of the lever has a number of adjacent first protrusions with first recesses in between, wherein the pin has a number of adjacent second protrusions with second recesses in between, and wherein at least one of the first protrusions engages into at least one of the second recesses and at least one of the second protrusions engages into at least one the first recesses.
