Abstract
The invention relates on the one hand to a progressivity device for a clutch friction disk, comprising a progressivity web (1) having a central rotation axis (X), having on one face of its external rim (1a) a series of blades (2) on which are configured at least two deformable pleats (20a, 20b) delimiting a region (20) intended to support a first friction lining (G1) and equipped with a stiffness element, and on the other face a second friction lining (G2) fastened symmetrically to the first lining (G1), wherein the stiffness element comprises at least one tab projecting below the region (20), one end of which is intended to come into abutment against the web (1) upon deformation of the pleats (20a, 20b), limiting the arching of the region (20); and on the other hand to a friction disk comprising such a device.
