Abstract
A structure for radially positioning a friction member in a damper disc comprises an output hub including a radial flange; a pair of side plates rotatably disposed at opposite sides of the flange; a torsion spring mechanism operable to circumferentially connect the side plates to the flange; and a friction mechanism rotatable fitted around the hub and associated to the side plate for generating a friction force in accordance with relative torsion between the side plates and the flange; the friction mechanism including an annular friction member, of which outer periphery is radially held and guided concentrically to a center of the disc by circumferentially spaced projections formed on the adjacent side plate.
Claims2
A structure for radially positioning a friction member in a damper disc comprising an output hub including a radial flange;
- a pair of side plates rotatably disposed at opposite sides of the flange;
- a torsion spring mechanism operable to circumferentially connect the side plates to the flange;
- and a friction mechanism rotatably fitted around the hub and associated to one of said side plates for generating a friction force in accordance with relative torsion between said one of said side plates and said flange;
- said friction member including an annular friction member, said one of said side plates having a plurality of circumferentially spaced projections each cut along three sides of said projection from said one of said side plates and bent inwardly at the fourth side and engaging the outer peripheral end of said annular friction member and radially holding and concentrically guiding said annular friction member concentrically to said hub.
