Abstract:
1. An anti-roll bar for a vehicle comprising a first half-bar having a first end connected to a coupling mechanism and a second end adapted to be connected to a first vehicle wheel, and a second half-bar having a first end connected to the coupling mechanism and a second end adapted to be connected to a second vehicle wheel, said coupling mechanism comprising a first piece able to be fixed to the first half-bar, a second piece able to be fixed to the second half-bar, the second piece being so arranged as to be moveable in rotation about an axis of rotation A relative to the first piece, characterized by the fact that it includes at least one elastically deformable elongate element coupled to the first and second pieces so that relative rotation of the first and second pieces about the axis of rotation A causes elastic flexion deformation of the at least one elongate element, the mechanism including an actuator able to rotate the at least one elongate element relative to the first and second pieces from a first state in which the at least one elongate element presents a first flexion stiffness for the elastic flexion deformation to a second state in which the at least one elongate element presents a second flexion stiffness for the elastic flexion deformation.
