Abstract
A clutch friction wheel, especially for a motor vehicle clutch, comprises two coaxial parts which are mounted for rotation of one with respect to the other about a common axis, with an annular damper between them. The damper comprises two rings one of which is in contact with a surface of the first coaxial part, while the other is in contact with a surface of the other part. The two rings of the damper are joined together by elastic members. The rings of the damper are disposed in a groove formed in one of the two coaxial parts, and they are divided into at least two ring segments, each of which includes an equivalent element of each of the two rings.
