Abstract

Un dispositif de friction d'embrayage (10) comporte un disque de friction (18) présentant deux faces de friction opposées (20) balayant chacune, sur un tour, une surface balayée S annulaire plane perpendiculaire à l’axe de référence (100), et un amortisseur de torsion (24) comportant au moins un premier organe tournant (28) solidaire du disque de friction (18), un deuxième organe tournant (30) mobile en rotation autour de l'axe de référence (100) par rapport au premier organe tournant (28), avec une plage de débattement angulaire bornée par un débattement maximal, et un ensemble d’un ou plusieurs ressorts (32, 33) générant un couple amorti avec une raideur angulaire moyenne K dans la plage de débattement, le débattement maximal correspondant à un couple maximal amorti C m. Les valeurs de S, exprimée en m2, K, exprimée en Nm/° et C m, exprimée en Nm, sont telles que : avec : (Figure d’abrégé: 4)A clutch friction device (10) comprises a friction disk (18) having two opposite friction faces (20) each sweeping, over one revolution, a planar annular swept surface S perpendicular to the reference axis (100) , and a torsion damper (24) comprising at least a first rotating member (28) secured to the friction disk (18), a second rotating member (30) movable in rotation around the reference axis (100) relative to to the first rotating member (28), with an angular travel range limited by a maximum travel, and a set of one or more springs (32, 33) generating a damped torque with an average angular stiffness K in the travel range, the maximum travel corresponding to a maximum damped torque C m. The values of S, expressed in m2, K, expressed in Nm/° and C m, expressed in Nm, are such that: with: (Abstract figure: 4)
