ABSTRACT:
A torsional damper device, for use in friction disks in automobile vehicle clutches, for example, comprises at least two coaxial parts rotatable relative to one another within defined limits and damper means adapted to oppose such relative rotation. The damper means comprise at least one friction ring, two annular members and an elastic prestressing member disposed axially between the annular members. The prestressing member is adapted to urge the friction ring axially against one of the coaxial parts. It and one of the annular members constitute a pair of members of which one has at least one primary transverse land which is circumferentially subdivided and of which the other has at least two secondary transverse lands which are axially offset and circumferentially subdivided and each of which is adapted to contact selectively the primary transverse land.
