Active anti-roll device

Abstract

Active anti-roll device to be fitted to a wheel set (4) of a motor vehicle (1), the said wheel set including two wheel supports (8b, 9b) coupled, with mobility in a so-called vertical direction (Z), to a frame (2) of the said vehicle, the said anti-roll device including a torsion bar (10) linked to the frame and the free ends of which are intended to be coupled respectively to the said wheel supports, characterised by the fact that it includes at least one actuator (13, 16) presenting a first zone connected to an eccentric point, relative to the median axis of the said vehicle, of the said torsion bar, by an actuator-bar linkage (14), and a second zone connected to the said frame by an actuator-frame linkage (15), the said at least one actuator presenting actuation means to create a relative displacement between the said first and second zones, the said at least one actuator being so arranged as to adjust a substantially vertical distance between the said eccentric point and the said frame as a function of a control signal, the said active anti-roll device including control means to transmit a control signal to the said at least one actuator.
