Abstract: The invention relates to an ARS (active roll stabilization) assembly (1) for vehicles, as well as to a suspension system equipped with such ARS assembly. The assembly comprises a torsion bar (3) and an actuator (10) for adjusting a torsion angle of said torsion bar. The ARS assembly furthermore comprises an additional torsion bar (5). This additional torsion bar is arranged such that its torsion axis extends substantially parallel to the torsion axis of the first, adjustable torsion bar, or coincides therewith.

Abstract: The invention relates to an active suspension assembly and a vehicle equipped therewith. The assembly comprises a bearing arm, spring and adjusting mechanism. In use, the bearing arm supports the second vehicle mass, for instance a cabin or wheel and is pivotally connected to the first vehicle mass, for instance a chassis, around a pivot axis; the spring mechanism produces a spring force that exerts a counter moment on the bearing arm that can counterbalance any external moment acting on said bearing arm; and the adjustment mechanism is arranged to vary said counter moment by altering the direction of the spring force and/or move its point of application in a first direction. The adjustment mechanism is furthermore arranged to move the point of application of the spring force in a second direction, in which the counter moment is not or hardly affected, but by which the effective spring stiffness of the suspension assembly is affected.
