ABSTRACT:
A clutch mechanism of the type constituted by a toothed wheel (3) driven by an endless screw (12), this wheel (3) being securable to a driven shaft (15) via two friction cones (5) disposed coaxially to the axial bore of the toothed wheel (3), and coacting, under the action of a control device (7, 13), with conical contact areas on the wheel (3). The toothed wheel (3) is made of a synthetic material, the bore of this toothed wheel (3) having an annular partition (16) delimiting on each side a shouldered recess for the reception of a metallic ring (4) secured in rotation to the wheel (3), this ring (4) comprising internally a conical contact area (4A) adapted to coact with the metallic friction cone (5).
