Abstract
A torsion filtering mechanism (22) has a first rotating member (24), a second rotating member (26) movable with respect to the first rotating member (24), a cam track (60) rotating with one (24) of the rotating members, and at least one associated cam follower (36) carried by the other (26) rotating member. The cam track (60) has, in a section plane perpendicular to the axis of revolution, a profile constituted by a plurality of circular arcs (A0, A1, A2, A3, A4) adjacent pairwise and having an intersection point pairwise. Any two adjacent circular arcs from among the circular arcs have different finite or infinite radii of curvature, and indistinguishable tangents at the intersection point.
