Friction clutch bearing an electric machine rotor, in particular for a motor vehicle

Friction clutch device including, on the one hand, a rotational drive flywheel (13) featuring a front extremity intended to be fixed to a drive shaft (11), consisting of the output shaft of an internal-combustion engine of a motor vehicle including an engine-block (62), and a rear extremity in the form of a hollow-shaped reaction plate (4) with a central recess (39) delimited externally by a friction face (37), and, on the other hand, a friction disc (20) comprising, at its outer periphery, at least one friction lining (16) for contact with the friction face (37) of the reaction plate (4), the said friction lining (16) being integral with a support (21) coupled to a central hub (15) tended to be fastened in rotation with a driven shaft consisting of the input shaft of a motion gearbox including a clutch bell housing (14) at least partly surrounding the reaction plate (4), wherein the drive flywheel (13), between its front and rear extremities, carries the rotor (6) of a rotating electrical machine (2) comprising a fixed stator (5) and in that a spacer (61) internally carries the stator;

• wherein the spacer (61) is interposed between the engine block (62) and the clutch bell housing (14) and is provided with features means for fixing to the engine block (62) and to the clutch bell housing (14);
• wherein the spacer (61) is of a single piece with the stator (5);
• in that the single-piece spacer (61) and stator are comprised of a first (180) and of a second (181) series of metal plates of different outer diameters, and wherein the second series of metal plates (181), forming the spacer (61), is of larger diameter than the first series of metal plates (180).
