Abstract
A progressive engagement friction disc, particularly for a clutch, comprises a hub, an annular washer coupled to the hub, and a circular series of blades fixed to the hub carrying friction linings on both surfaces. The blades comprise plane areas extending at two slightly different levels connected by ramps. One of the ramps is divided in the direction of its level lines into at least two parts which are inclined in the same direction and which are offset relative to one another in a transverse direction relative to their extension, thus making it possible to increase the useful surface of the area to which the corresponding lining is riveted.
