Patent ID: 7318403

Claim:
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 ), 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 ), said friction lining ( 16 ) being integral with a support ( 21 ) coupled elastically, by way of a torsion damper ( 20 a ), to a central hub ( 15 ) intended to be integrated in rotation with a driven shaft, wherein the torsion damper ( 20 a ) penetrates into the central recess ( 39 ) of the reaction plate ( 4 ) and the drive flywheel ( 13 ), between its front and rear extremities, carries a rotor ( 6 ) of a rotating electric machine ( 2 ) comprising a fixed stator ( 5 ), and wherein the torsion damper ( 20 a ) includes, on the one hand, a first guide washer ( 29 ) integral with the support ( 21 ) and with a second guide washer ( 30 ), and, on the other hand, a web ( 34 ) arranged between the two guide washers ( 29 , 30 ), and linked in rotation, possibly after taking up play, with the hub ( 15 ), and wherein the second guide washer ( 30 ) is installed in the central recess ( 39 ) of the reaction plate ( 4 ).
