Patent ID: 7568569

Claim:
Friction clutch, comprising at least one damper ( 22 ) having: rotating input ( 24 ) and output ( 26 ) elements, elastic elements with a circumferential effect carried by first ( 28 ) and second ( 30 ) guide washers which are connected in a rotationally fixed manner to a first of the input ( 24 ) and output ( 26 ) elements and by a web ( 36 ) connected in a rotationally fixed manner to a second of the input ( 24 ) and output ( 26 ) elements, friction assemblies ( 44 ), which are activated by relative angular displacement of the guide washers ( 28 , 30 ) and of the web ( 36 ) and which comprise a friction element ( 46 ) capable of being coupled to the web ( 36 ) via complementary circumferential stops, referred to as coupling stops ( 48 A, 48 B), which interact only when this web ( 36 ) is displaced angularly in a predetermined direction with respect to the guide washers ( 28 , 30 ), wherein the complementary coupling stops ( 48 A, 48 B) are provided on the friction element ( 46 ) and an attached element ( 50 ) that is distinct from the web ( 36 ) and from this friction element ( 46 ) and is connected in a rotationally fixed manner to the web ( 36 ).
