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).
