A full loadshare coilspring bogie suspension comprised of two loadshare beams (3) sitting above four coilsprings (2) atop two axle assemblies (1) of either live axle or independent axle configuration the axles (1) being located to the chassis (6) by 'A' Arms and control rods and suspended by the loadshare beams (3) and coilsprings (2). This loadshare coilspring bogie suspension has improved the level of performance for suspensions of this type as it offers several advances by giving increases in all of the parameters of ride quality, wheel articulation, chassis platform stability and reduced chassis torque input, all resulting from the interaction of the loadshare beams (3) with the coilsprings (2).

L'invention comprend une suspension à bogies avec ressorts à boudin à répartition totale des charges. Cette suspension comprend deux traverses (3) de répartition des charges reposant sur quatre ressorts à boudin (2) au-dessus de deux ensembles d'essieux (1) présentant une configuration d'essieux moteurs ou d'essieux indépendants. Ces essieux (1) sont raccordés au châssis (6) par des bras 'A' et des tiges de commande, et sont suspendus à des traverses (3) de répartition des charges et des ressorts à boudin (2). Le système de suspension selon l'invention présente un niveau de performance amélioré pour les suspensions de ce type. En effet, l'interaction des traverses (3) de répartition des charges avec les ressorts à boudin (2) permet d'augmenter tous les paramètres de confort de roulement, d'articulation des roues, de stabilité du châssis plate-forme et réduit l'entrée de couple de châssis.
