ABSTRACT:
This invention relates to a torsion damping device, in particular for automotive vehicles, comprising two coaxial parts with a hub and a damper plate, and also having an intervention member for modifying the operating characteristics of the torsion damping device. The intervention member is able to occupy two working positions, and comprises at least one weight, moveable radially under the influence of centrifugal force and comprising a trapezoidal tenon which is engaged in a mortice of complementary trapezoidal shape formed in the hub, the weight being biassed against the action of centrifugal force by a resilient spring bearing at one end on the damper plate so as to urge the weight towards the base of the mortice.
