Abstract
A torsion damper, in particular for a motor vehicle clutch, comprises two coaxial parts, namely a primary coaxial part and a secondary coaxial part which are mounted for relative rotation against the action of springs, with friction member also being arranged to act between the two coaxial parts. The friction member comprise a radially acting friction ring in the form of a sleeve, meshing, with a clearance, with one of the coaxial parts, together with a radially acting spacing ring, which is coaxial with the friction ring and which engages either the outer or the inner periphery of the latter, the spacing ring being mounted on the other one of the coaxial parts for rotation with that part.
Claims10
A torsion damper comprising:
- a primary part;
- a secondary part;
- means mounting the said primary and secondary parts coaxially with each other for relative rotation of said coaxial parts;
- resilient means disposed between the coaxial parts for resisting said relative rotation;
- and friction means operatively arranged between the said coaxial parts, wherein the said friction means comprises a radially acting friction ring in the form of a sleeve, meshing with a first one of the coaxial parts and defining a clearance between itself and the first one of the coaxial parts, and a spacing ring coaxial with the said friction ring and mounted on the other of said coaxial parts, the spacing ring being in engagement with one of the outer and inner peripheries of the friction ring, wherein the spacing ring is a profiled leaf element and comprises a small local portion in local engagement around a peg carried by and anchored in the other one of said coaxial parts whereby the spacing ring is mounted on the other one of said coaxial parts for rotation therewith, said spacing ring being gripped between said peg and the other one of coaxial parts.
