Title (EN) VEHICLE SUSPENSION SYSTEM
(FR) SYSTÈME DE SUSPENSION DE VÉHICULE
Abstract:
(EN) A vehicle suspension or damping system (100) includes a coupling component (2), a torsion bar (130), a plurality of lever arms (150), a fluid based damping device (110), a coil spring (120), and an electronically controlled valve-based damping device (160). The torsion bar converts an external load that is transferred to the torsion bar via the coupling component into a rotational displacement of the torsion bar. Each of the lever arms is adapted to physically move with the torsion bar when said torsion bar experiences a rotational displacement, and each of the fluid based damping device, coil spring and electronically controlled valve-based damping device damps physical movement of its respective lever arm. One or more damping devices can be coupled to each such lever arm. Alternative applications for the disclosed suspension and shock damping system can include load transferring manufacturing machinery and earthquake damping for buildings and other structures.
(FR) L'invention porte sur un système de suspension ou d'amortissement de véhicule (100) qui comprend un composant de couplage (2), une barre de tension (130), une pluralité de bras de levier (150), un dispositif d'amortissement à base de fluide (110), un ressort hélicoïdal (120) et un dispositif d'amortissement basé sur une soupape commandée électroniquement (160). La barre de torsion convertit une charge externe qui est transférée à la barre de torsion par l'intermédiaire du composant de couplage en un déplacement de rotation de la barre de torsion. Chacun des bras de levier est apte à se déplacer physiquement avec la barre de torsion lorsque ladite barre de torsion subit un déplacement de rotation, et chacun du dispositif d'amortissement à base de fluide, du ressort hélicoïdal et du dispositif d'amortissement à base de soupape commandé électroniquement amortit un déplacement physique de son bras de levier respectif. Un ou plusieurs dispositifs d'amortissement peuvent être couplés à chacun de ces bras de levier. Des applications alternatives pour le système de suspension et d'amortissement des chocs divulgué peuvent comprendre des machines de fabrication à transfert de charge et l'amortissement sismique pour des bâtiments et d'autres structures.
