Abstract
A clutch device has a friction transmission element which has a base with at least one friction surface, at least one control element for acting on a damping device, and at least one radial support which cooperates with a stop and has a plurality of lugs which extend at least substantially radially in direction toward the stop and which are at least substantially brought closer to the stop up to a gap before the stop when the friction transmission element is stationary, while, at speed, at least a portion of the lugs comes in contact with the stop. The lugs are connected to the base via a bend which causes an axial offset with respect to the base, the bend allows a displacement of the lugs in direction toward the energy accumulators, and the lugs are completely covered by the stop in an axial extension direction.
