摘要

Friction device for a clutch, notably for automotive vehicle hired and clutch for automotive vehicle hired this friction device comprises two friction linings and a support (28) comprising a hub (34) extended radially in at least one vane (36) perifu00e9ri CA is bounded by two edges angular (38a, 38b).The vane (36) includes a side support (44) connected to the first Garrison and at least one face of the support (46a, 46b, free 55) in contact with the second garrison. The faces of the support bound (44) and free (46a, 46b) are separated from one another by a step of straw (S0A, s0b), bounded by two Lines (52A, 54a; 52b, 54B) of folding.Each edge angle (38a, 38b) covers a part cu00f3ncava (60a, 60b) that delimits the step of straw (S0A, s0b) and parts of the sides of the support bound (44) and free (46a, 46b) adjacent to that step vane (S0A, s0b).The part cu00f3ncava (60a, 60b) form a curve cu00f3ncava that in any point that delimits the step of straw (S0A, s0b), presents a tangent to an angle comprised between 70 and 110 with the folding line (52A, 54a; 52b, 54B) closest to the point at which it is considered to be the the tangent.
