A stabilising assembly for a vehicle comprising: - a chassis forming a sprung portion of the vehicle, - a stabiliser system comprising two arms consisting of a first arm and a second arm, and wherein the first arm has a proximal end articulated to the chassis, and a distal end at which a first unsprung portion of the vehicle is secured, said distal end being configured to move while being contained in a first plane relative to the chassis and wherein the second arm has a proximal end articulated to the chassis, and a distal end at which a second unsprung portion of the vehicle is secured, configured to move while being contained in a second plane relative to the chassis and wherein the first arm and the second arm release an interspace between the two planes (P1, P2), consisting of the first plane and the second plane, characterised in that said stabiliser system comprises - at least one flexible link linking the first arm to the second arm, configured to work in traction, tending to bring the two arms (3, 4) close to each other, - a load-carrying device, articulated to said chassis, extending in the inter-space between the two planes (P1, P2), bearing on the at least one flexible link, - a bracing system opposing the approach of the two arms (3, 4), and wherein the load-carrying device and the at least one flexible link are configured to cooperate together with a transfer of the load of said load-carrying device on said at least one flexible link so that said at least one flexible link provides a tensile force between the first arm and the second arm correlated to the load of said load-carrying device, the tensile force tending to bring the two arms (3, 4) close to each other being balanced by a contrary force due to the bracing of the two arms (3, 4) by the bracing system. - a chassis forming a sprung portion of the vehicle, - a stabiliser system comprising two arms consisting of a first arm and a second arm, and wherein the first arm has a proximal end articulated to the chassis, and a distal end at which a first unsprung portion of the vehicle is secured, said distal end being configured to move while being contained in a first plane relative to the chassis and wherein the second arm has a proximal end articulated to the chassis, and a distal end at which a second unsprung portion of the vehicle is secured, configured to move while being contained in a second plane relative to the chassis and wherein the first arm and the second arm release an interspace between the two planes (P1, P2), consisting of the first plane and the second plane, characterised in that said stabiliser system comprises and wherein the first arm has a proximal end articulated to the chassis, and a distal end at which a first unsprung portion of the vehicle is secured, said distal end being configured to move while being contained in a first plane relative to the chassis and wherein the second arm has a proximal end articulated to the chassis, and a distal end at which a second unsprung portion of the vehicle is secured, configured to move while being contained in a second plane relative to the chassis and wherein the first arm and the second arm release an interspace between the two planes (P1, P2), consisting of the first plane and the second plane, characterised in that said stabiliser system comprises - at least one flexible link linking the first arm to the second arm, configured to work in traction, tending to bring the two arms (3, 4) close to each other, - a load-carrying device, articulated to said chassis, extending in the inter-space between the two planes (P1, P2), bearing on the at least one flexible link, - a bracing system opposing the approach of the two arms (3, 4), and wherein the load-carrying device and the at least one flexible link are configured to cooperate together with a transfer of the load of said load-carrying device on said at least one flexible link so that said at least one flexible link provides a tensile force between the first arm and the second arm correlated to the load of said load-carrying device, the tensile force tending to bring the two arms (3, 4) close to each other being balanced by a contrary force due to the bracing of the two arms (3, 4) by the bracing system.
