Abstract
Torsion-damping device, particularly in an inertia flywheel forms the reaction plate of a clutch. The damping device comprises two coaxial parts capable of limited rotation relative to each other against the action of springs mounted between pivoted pedestals. Elements of damping material are disposed near engagement zones between the pedestals and each of the coaxial parts.
Claims22
A torsion-damping device, particularly for a clutch said torsion damping device comprising two coaxial parts mounted for limited rotation relative to each other, a first of said coaxial parts comprising two substantially parallel annular flanges and a second of said coaxial parts comprising at least one web arranged axially between said flanges, and parts of pedestals mounted on one of the parts, springs arranged substantially circumferentially between said pedestals, each of said pedestals having first engagement means cooperable with matching engagement means on one of said coaxial parts to define therebetween at least one first rotary bearing zone, and second engagement means cooperable with matching engagement means on the other of said coaxial parts to define therebetween at least one second rotary bearing zone, at least one of said coaxial parts and pedestals having damping means of elastic material disposed proximate to said engagement means for damping impacts between said pedestals and said coaxial parts.
