Abstract
A driver plate for a torsion-suspended clutch plate of a motor vehicle friction clutch includes an annular disk-shaped lining support (1) composed of a plurality of segments (17), in the form of stamped sheet metal parts, and a reinforcement part (5), provided with windows (13) for receiving springs (15) of a torsion spring system of the clutch disk. The outer circumference of the reinforcement part forms a centering edge (21) to which the segments (17) are welded, resting against it with inner arc-shaped concave contact edges (19). The segments (17) can be produced with a comparatively small amount of stamping waste. The contact edge (19) of the segments (17) can have comparatively rough tolerances, if the openings (11) required for fastening of the friction linings are cut into the lining support (1) after the welding process.
