Abstract: The invention relates to a friction device for a clutch, particularly of a motor vehicle. The inventive friction device comprises first and second axially-spaced coaxial friction lining members which are defined by opposing friction faces. The device also comprises means for linking the two friction lining members which are solidly connected to one another. The first friction lining member is essentially ring shaped. The aforementioned linking means comprise linking tongue elements which are each equipped with a first end for solidly connecting to an inner edge of the first friction lining member and a second end for solidly connecting to the second friction lining member. Moreover, a deviation angle is provided between said first and second connecting ends, which can vary according to the axial spacing of the two friction lining member.

Abstract: This device (10) comprises first (24A) and second (24B) friction lining members, substantially annular and coaxial, separated axially and delimited by opposing friction faces. The first friction lining member (24A) comprises a radially external part (32A) comprising a friction lining (26A), a radially internal part (30A) intended to be fixed to the second friction lining member (24B), and elastic connecting tongues (35A) each provided with a first end (36A) for connection to the radially external part (32A) and a second end (38A) for connection to the radially internal part (30A), the first (36A) and second (38A) connecting ends having an angular offset between them that is variable according to the axial separation of the two friction lining members (24A, 24B).
