The friction coupling device (15) comprises clutch coupling means (125,127) acting in order to establish a coupling, when in an engaged position, or to suppress a coupling, when in a disengaged position, between the first and second mass of inertia (3,13) and the second mass of inertia (13) is mounted in such a way that it turns with the driving means (7) when the clutch coupling means are in an engaged means and mounted in such a way that it is essentially free from rotation in relation to the driving means in a disengaged state, thereby making it possible to move between a high inertia state in the engaged position and a reduced inertia state in the disengaged position. |
