Abstract
A clutch disk comprises an annular plane support member at the periphery of which are elastically deformable parts adapted to deform when the disk is subjected to axial compression. Two friction facing members are disposed one on each side of the support member and locally attached to the deformable parts. Thus the portion of the disk comprising the friction facing members is elastically compressible between an expanded inoperative configuration and a flattened operative configuration. The deformable parts are substantially plane in the inoperative configuration. The friction facing members have inside surfaces on which are bosses alternating with recesses and the friction facing members are attached to the deformable parts by means of these bosses. The bosses on each friction facing member are aligned with the recesses on the other member. Thus compressing the disk from its inoperative configuration to its operative configuration causes elastic deformation of the deformable parts by virtue of interpenetration of the bosses and the recesses in the axial direction. Each boss is stepped and the recesses are wider than the bosses, so that voids are provided between the edges of the re…
