Abstract
The invention relates to a torsional-vibration damping hub for a clutch friction plate. The hub comprises two coaxial parts mounted for limited relative angular displacement against the action of circumferential springs disposed between the parts. Axially-acting spring means are also provided for acting on friction means disposed between the parts, and these spring means comprise a clamping disc provided with elastically deformable, radially projecting lugs. These lugs extend from the internal periphery of the clamping disc and are each bent to form a dihedral angle. This arrangement enables an improved distribution of the axial clamping force over known arrangements.
Claims10
A torsion damping device for a motor vehicle clutch, said torsion damping device comprising two coaxial parts mounted for limited relative angular movement within a predetermined sector, a plurality of circumferentially spaced elastic means interposed circumferentially between said coaxial parts, at least one friction washer interposed axially between said coaxial parts, an axially-acting elastic clamping means for exerting an axial force against said friction washer, said elastic clamping means comprising a plurality of elastically deformable lugs projecting radially between circumferentially adjacent ones of said plurality of elastic means, each of said lugs having a radially inner end section separated from a radially outer base section by a chordal bend, said radially inner end section and said radially outer base section defining a dihedral angle with each other, said radially inner end section being cooperable to exert the axial force against said friction washer.
